In short
Dr. Mary Pardee argues that midlife weight gain is not mainly due to “slowed metabolism” (metabolism is said to stay largely stable from ages 20–60). Instead, she emphasizes under-exercising (especially resistance training), increased appetite/cravings from hormonal shifts, and the role of ultra-processed foods. She also criticizes longevity “quick fixes” like supplement stacks and NAD IV drips as overhyped, and says supplements are a minor “last bit,” not the core of longevity.
Key claims
low muscle mass (sarcopenia) is linked to 60–100% higher mortality risk and triples osteoporosis risk; sedentary lifestyle, hearing loss, and high blood pressure are major dementia risk factors. She frames heart disease prevention as reducing ApoB and pairing that with exercise.
Notable examples
a statin nocebo study on myalgia; LDL/ApoB targets (around ApoB 55) and PISA trial plaque data at LDL ~50; hip-fracture mortality percentages by age.

Is there any truth to that? No, and I view supplements as the last little bit in longevity, not the majority of the pie. Muscle is one of the cornerstones for longevity and health span. And so we look at sarcopenia, people with low muscle mass. They have 60 to 100 % higher risk of mortality. And your risk for osteoporosis triples. What's your take on why people gain weight as they age? When women come in in their 40s, 50s, or men, and they say, oh, I'm just getting old and my metabolism slows.
0:40I go, I'm sorry, it's not because of that. What if the way you're aging is optional and you could start slowing it down today? Dr. Mary Pardee is one of the leading experts in longevity and preventive medicine. A former performance researcher for the U.S. government. She's here to break down the science of extending your years. Strengthening your body and upgrading the quality of your years. What do you say if someone's worried about dementia? Top four risk factors for dementia that accounts for 30 % of global dementia cases is going to be number one, a sedentary lifestyle. So exercise, hearing loss, high blood pressure.
1:13And then what's one thing about longevity that you wish people would stop obsessing over? There's so many things. So good, so good, so good. New summer arrivals are at Nordstrom Rack stores now.

That's O-L-L-Y dot com. Welcome to the Dr. Brighton Show, where we burn the BS in women's health to the ground. I'm your host, Dr. Jolene Brighton, and if you've ever been dismissed, told your symptoms are normal or just in your head, or been told just to deal with it, this show is for you. And if while listening to this, you decide you like this kind of content, I invite you to head over to drbrighton.com, where you'll find free guides, twice-weekly podcast releases, and a ton of resources to support you on your journey.
2:42Let's dive in. This is the way to longevity and wellness. Is there any truth to that? No. And I think this is a piece that people are really missing the boat on where people come in their own 10, 20, 30 supplements, hoping that it's going to help them live longer or improve their quality of life. And I really view supplements as the last little bit in longevity, not the majority of the pie. Except that all of the leaders that you see online, not necessarily in the lab, in longevity are saying, this is the new supplement. This is the thing that's going to extend our life. The clickbait is real.
3:21I agree with that. It's all over social media. People want to sell things. People want to make money and people buy supplements. The global nutraceutical industry itself is gigantic. We're talking trillions of dollars. And so it's an easy way to make money. And I don't think a lot of it is warranted. And so there's some interesting things that are coming out to keep your eye on. But right now, in terms of should you take a supplement or should you do all of these other things that we know 100 % will extend your lifespan, improve your health span, my money is not on the supplement. Well, I think it's interesting too, because you raise what a big industry this is.
4:00And there are people who gravitate towards supplements because they feel like, okay, well, pharma, bad, I'm anti pharma, not realizing that pharma actually owns the most profitable supplements that you can buy in the United States. And so clever on pharma, we'll give them that. But I think sometimes people think like, well, if it's natural, then it's just better. I would love to hear your take, you know, medications, nutraceuticals, natural is more better. Is that what people say? But they say natural must be better. What are your thoughts on that? Yeah, this appeal to nature fallacy. And I didn't know about this all the time.
4:40So I became a naturopathic doctor. And it was one of the things that I was interested in is should we stay more natural. And at this point in my career, after reviewing everything, like natural does not mean better. And we know that intuitively, right? We have poison ivy. Do we want to eat that because it's natural? Absolutely not. And then we have things that are synthetic, like you can even look at some prescription medications that are potentially going to improve your health span and lifespan. And so, and then people that are anti pharma, you don't have to think of medications as the opposite one, but would you say that whey protein is good for you?
5:15There's no whey protein tree out there. It is processed. We have to do a lot of things to get it. And yet most people would say, yeah, that might be beneficial for your health. And so we have to really start to question things beyond this natural is better because I think that one has already gone by the wayside and it's just not what's going to be helpful in terms of evidence-based medicine. And I think people also need to realize that there are some things that are natural that pharmaceuticals have then standardized. So, you know, there's a lot of times where people will talk about willow bark, you know, versus aspirin, or you're talking about some cardiovascular medications.
5:54And it's like, sure, you could get a tincture of these things, but it's not standardized. And when you need a therapeutic dose and you have to know that somebody's in a therapeutic window and actually understand the peaks and the troughs of that medication, it's really important to have something standardized. So sometimes we iterate on what is natural and improve it for the use of medicine. And I think, you know, as somebody who likes to live every day and takes a thyroid medication so that I can do that, you know, there's times that people say to me like, oh, well, you must be anti-pharma because you studied naturopathic medicine.
6:28And I'm like, I studied naturopathic medicine because I wanted a foundation in nutrition, lifestyle, the things that don't require me for you to be healthy and also the training in pharmacology and having prescriptive rights and being able to support people in those ways. So I'm like, you know, back when, cause I'm older than you, back when I was in school, there was no functional medicine. There was not like these, um, nobody was a, you know, this integrative doctor that was actually practicing lifestyle medicine. There was no board certification. This was the only path. If you wanted to be that holistic practitioner who was like, I understand the utility of a dietician and I will definitely leverage them.
7:08Yeah. And that's such a great point in terms of a lot of the medications we use today are derived from natural products. And we have just isolated the thing that we know works and we've gotten rid of all of the things that could potentially cause side effects and made it so it's standardized in terms of dosing. If you look at, for instance, statin medications, people will come to me and they're on red rice yeast. And then I want to switch them to something like Crestor and they'll say, well, why? This is natural. It's better. And I'll tell them, well, there's a bunch of reasons, but the Crestor is going to work better to lower your apolipoprotein B.
7:43It's a synthetic. We see less side effects with Crestor versus some of the non-synthetic versions of statins. And so that ability to have and know the exact dose and purity of what you're taking over time just almost guarantees you're going to have better effects. And we have so much more research around these things as well. People get afraid of statins because of the side effects, but there are ways to help mitigate that. What do you talk to your patients about? Yeah, well, the first thing I say is that statins are one of the most demonized medications that we have out there for some reason.
8:18So social media took hold of them. Podcasts have taken hold of them. And I think a lot of the side effects that they talk about are unwarranted. If you exercise a lot, you have potential side effects of tearing a muscle, right? Getting injured. But we would never tell people don't exercise because those side effects exist. Everything that we do and enter into our life is going to have potential side effects. It's all about the risk-benefit ratio. And when it comes to heart disease, heart disease is the number one cause of death. And ASCVD, atherosclerosis, plaque formation on the arteries, is completely preventable with what we know right now.
8:55And so because it's such an important thing, those benefits start outweighing potential risks pretty heavily, especially when we have so many different therapeutics now to lower APOB levels that we're not reliant just on statin medications. If somebody doesn't tolerate statins, first of all, they're idiosyncratic, meaning that somebody may not tolerate Libitor, but they do great on Crestor. And so you just need to know how to move around them, change dosing. You can even do every other day dosing. And then you can go to other classes of medications if that's not working for somebody. So we've got benpatoic acid, we have Zetia, we have PSK9 inhibitors.
9:30We can talk about lifestyle as a piece of that as well. We now have these RNA medications. so there's just so many different options that it doesn't have to stop at statins and I think we need to be more open-minded about it there was a research study that was really interesting that took people who said that they have um statin-induced myalgia muscle pains from statins and they did a placebo control with them where at one phase they gave them the statin at the other phase they gave them placebo they didn't tell them and then they swapped within the same group and what they found is that the people that actually had myalgia from the statin they would only get the myalgia when they were taking the statin but they should not get it when they took the placebo and what they saw is that it was a fraction of the people who complained that they had this statin-induced myalgia actually had it so a lot of this is like the nocebo effect that's going on as well and there's and there's a real thing yeah i want to talk more about you know heart disease.
10:28And because when we talk about longevity, it's not just like, how do you live longer and look healthier? It's also how do you prevent these number one killers, which especially in women, we know not only is heart disease, why are we not talking about heart disease more in women? Like we get a whole month to breast cancer, important. However, it's heart heart disease that's going to get us and it's often medicine who's going to miss us because we present differently. So I definitely want to talk to you about that. But I did want to ask you, because we started talking about supplements. Are there supplements that you think are truly worth it for longevity, especially when you're layering it on the framework of great nutrition lifestyle, like you're doing the right things already?
11:13Yeah, there's some that are interesting to me that I'm keeping an eye on. For me, I think creatine is kind of a no brainer. It has good results in terms of strength, power outputs, also some cognitive things like potentially increasing memory and just like overall cognitive function. So that's one that I think is an easy one. It's cheap, creatine monohydrate. It tastes like garbage most of the time. I don't mind it. You don't mind it. I don't like to, I mix it with electrolytes to like get it down, but I always get messages from people that are like, you should just take creatine gummies. I'm like, oh, with like 10 to 15 grams of added sugar to my day.
11:53Like, no, thank you. Like, why take the creatine then? For some reason, the gummies for creatine taste garbage to me. That's why they have so much sugar, though. They have to probably have the good ones probably are low. All my friends who are dentists would seriously slap me if they knew I was eating gummies with that much sugar. It's sticking to my teeth. Oh, what we do. The other one, whey protein has great research to maintain and build muscle. We're going to talk about muscle today, I'm sure, but muscle is one of the cornerstones for longevity and health span. I think of whey protein as a food.
12:28So if you would rather eat chicken than eat chicken kind of thing, I think a lot of people are trying to get in a little bit more protein between meals, especially if you're in more of an anabolic kind of growth phase. So that can be a helpful one as well. Vitamin D I use just to get people to a good level. So if they come in and their vitamin D is already at a 50 on their own and maybe it's even winter time. So we're not even thinking it's due to being outside for the summer, then I'm not going to supplement them at all. We'll just keep monitoring. Um, but if somebody comes in low, then I think supplementing with vitamin D makes what do you consider low below 40.
13:01So I want people between like the 40 and 70 ish range, ideally. And, um, so vitamin D trying to think if there's any others, there's some interesting ones, which is like alpha-ketoglutarate, I've got my eye on right now. It's mostly animal data. It's kind of interesting, but that's where I leave it. So I'm personally not taking it. I just think that it has a potential to maybe show something. People always want to know about NAD or NM, the precursors to NAD. And that's one of the ones that I think is potentially interesting. Right now, there's no way I would ever go to a clinic and get an IV NAD drip.
13:38There's not even close to the research that I think that warrants that price tag. And then why not just do a precursor like NR, nicotinic riboside, which actually may get into the cells better and increase NAD intracellularly more efficiently than actually doing an IV drip on it. But still, the whole NAD, NR, kind of for longevity and health span, specific groups and populations, I think it's very likely to have some benefits. But for the vast majority of us who are healthy and just want to live a better, longer life. Like, I'm not sure yet. So you can see, like, I'm really skeptical and there's ones I'm interested on, but like nothing that's like a home run for me other than the ones that I mentioned in the beginning.
14:19Yeah, it's very interesting to me to see how NAD has shifted. So four to seven years ago, NAD IV was really affordable. And when I went through IVF, NAD was something that I did, IV, but I also was supplementing with it. I have seen it explode and now seeing the price tag of like$500 for an IV. And I'm like, what happened? Why does it suddenly cost so much more? Because the demand is there and welcome to capitalism. The demand increased and now we see it's, you know, a very, very hot one. What do you think about Urolithin? Urolithin's one of the ones that I'm interested in, totally interested in.
14:59Again, I don't think that there's anything out that's like, yes, home run, everybody should be on it. It's gonna extend your lifespan. But I think it's an interesting one for like mitochondrial health and things like that. I just need more data to make it warranted because otherwise you're taking that. Then you get into the group, you're taking 20 things that are maybes and then you don't know what actually is benefiting you. So I would rather, and if you really look at all the data around this, you are looking at like the last 2 % of, you know, improvements that you're going to get. If you really want to move the needle, it's none of this.
15:32It's all of the other stuff that we're going to talk about, which is going to give you the most bang for your buck. And I'm really happy to get the most bang for my buck and like wait on the few kind of question marks and maybe add them in at some point. Before we get to that, I want to ask you about rapamycin. Yeah. Rapamycin, Matt Kaeberlein is a colleague and friend. I had him on my podcast. Um, he's one of the leading experts in rapamycin and that one I'm really excited about. And that is one that I potentially will take in my lifetime. Um, I'm in my 30, late thirties now. And I think I'm going to wait closer to like four mid forties.
16:04Um, but rapamycin I'm really interested on for, because I'm an APOE4 carrier. So APOE4 carriers, we think that there may be a potential increase in benefit with rapamycin in terms of risk for Alzheimer's dementia. Um, and, but yeah, the RAPA trials are ongoing. Like we're going to learn stuff in the next five years about what it's doing in humans in terms of lifespan. But I think it's really interesting, really fascinating. When I had him on my podcast, I'm like, what do you think right now in terms of longevity? He goes, we know nothing. And this is the guy that's like the lead researcher, one of them in rapamycin.
16:38So I think it's got great potential, going to keep a close eye on it. And yeah, I think I potentially, when you think about Alzheimer's disease, the risk benefit ratio changes versus other things, right? Because you, I really don't want to get Alzheimer's. So if there's something that I can do that has relatively low risk, even if it's potentially not going to help, I'm more likely to take it versus doing that for like, you know, preventing a muscle tear. I'm like, I don't really care about that. Why would I do that? One thing I hear from women all the time is that they're struggling with symptoms like hot flashes, sleep disruptions, and brain fog, but aren't sure where to turn to for help.
17:17Menopause is inevitable, but suffering through it isn't. That's why I want to tell you about Alloy. Alloy is a digital health platform that connects you with a menopause-specialized doctor who can create a personalized treatment plan tailored to your needs, all from the comfort of your home.

18:06Plus, you'll get$20 off your first order today. That's M-Y-A-L-L-O-Y.com, code Dr. Brighton. Mm-hmm. I feel the same, like with creatine, cognizant, like some of these supplements that have potential with preserving brain health. I'm like, you know, well, see, I'm older than you. So I'm like, I don't really have time to wait for the research, which is where a lot of my colleagues are at. So I'll be turning 45 next year. Rapamycin is coming down the pipeline for me because I can't wait on this study, right? If it's saying it can extend your reproductive years by three to five years. So delaying menopause so that you get more of the brain, the heart, the bone benefit.
18:47I have to start this now. I can't wait for the trial. And I do that with informed consent. I have friends who are older than me and they're like, I'm already on it. And let's see what happens. I'll be my own N of one. These things are not without side effects. So I say this with the caveat of informed consent, my own informed consent, and you need the same thing. You brought up APOE. Not a lot of people are going to know what that is. Can you explain that? Yeah, ApoE is a genetic marker for Alzheimer's disease. And so you get one copy of your ApoE from mom, one copy from dad. And from each of them, you either get a two allele, a three allele, a four allele.
19:25And each of those confers either less risk, neutral risk, more risk. And so the ApoE four allele is the allele that has an increased risk for Alzheimer's dementia. And if you have one copy, it increases your risk a little bit. If you have two copies, meaning both mom and dad gave you the APOE4, your risk is much higher. Now, if you have two copies, it does not mean you get Alzheimer's disease. There's many people with two copies who won't get Alzheimer's disease. So it's not a deterministic gene. And we want to say, even if you have one, but especially if you have two, we're doing all of the other things that we know to reduce your risk from lifestyle, because lifestyle is going to be a huge component of risk for dementia.
20:09So speaking of lifestyle, let's get into how does muscle actually affect how long we live? Muscle, I think is, we're not talking, we're talking way too much about supplements, not enough about muscle. And that's what I was. But seriously, we had to start there because like, that's where all the hype is, right? Totally. It's one thing. And to be fair, as one of two countries in the world where pharma is allowed to advertise to us, we have been conditioned by watching TV, at least, you know, when I was younger, the ads were always running. We didn't have streaming channels to negate that of saying here, like this pill, this pill, like, you know, she's running through the field with balloons and she's so happy because this pill.
20:50And so I think it's really shaped our mindset. And what we have to do is start reminding people that so much of what will actually move the needle is what you do every single day. Yeah. And that's why I I love our profession too. Lifestyle is like the cornerstone. So muscle plays a really important role in the body. And people think of it as a structural kind of tissue, which it is, but it's much, much, much more than that. It's very active metabolically. And so the amount of muscle you have on your body increases. If you have more muscle, it increases your basal metabolic rate. How many calories you're actually burning at rest also increases fat oxidation.
21:28Muscle secretes different things from it as well. So it's very active. It puts out things called myokines and we have anti-inflammatory myokines that are cardioprotective for our heart. We have things that are secreted that reduce tumor necrosis factor alpha, which is an inflammatory cytokine. And we have things that will actually like, there's one called irisin that's released from the muscle that is anti-neoplastic, can reduce certain types of cancers. And so we have all of these things coming from muscle that are much more than just structure, but actually improving our insulin sensitivity.
22:07And muscle acts as this pump when we're walking or when we're lifting something. And the actual contraction of the muscle can help with something called insulin independent glucose uptake. So that is when you get sugars in your blood and it goes into the muscle cell, takes up and doesn't need insulin to unlock that cell to let it in. So typically insulin has to be around to let sugars into the cells, but exercise alone acts as a different way to get those sugars in. So reducing your risk for insulin resistance, prediabetes, diabetes. And then we also know that muscle helps with nitric oxide signaling to improve our endothelial function of the inside of our arteries to reduce the risk for heart disease and things like that.
22:55And then if we just start to look at the stats behind how much muscle somebody has on their body and what it actually does long-term. So if we look at one end of the spectrum, we've got sarcopenia, people with low muscle mass and people with low muscle mass have a 60 to a hundred percent higher risk of mortality with sarcopenia, 60 to 100 % higher risk of mortality. It's not a little bit. These are huge numbers. They have longer hospital stays. If something happens, they stay sick longer. If somebody is diagnosed with cancer and they had sarcopenia prior to being diagnosed, they have a 49 % higher risk of mortality from that cancer compared to if they had normal muscle mass beforehand.
23:43And so muscle matters. It is making sure that we don't fall. It's making sure that we actually can shower ourselves by the time we're 80, 90 into our hundreds as well. And then this all plays a role when we talk about osteoporosis, because if you have low muscle mass, your risk for osteoporosis is 3x what it was. So it triples. And it's about one in two postmenopausal women will have an osteoporotic fracture at some point in their lives. That's one in two, that's 50 % of women. Huge, huge, huge. And we don't want to break a hip. So if you look at the stats around hip fractures, and we'll just look at women, but if you're 70 years old and you break a hip, 5 % of those women who break a hip at the age of 70 will be dead within two years.
24:34If you're 80 years old, you break a hip and you're a woman, it's about 11%. That's one in 10 of those women will be dead within two years. And if you are 80 plus years old and you break a hip, it's about 26 % of those women will be dead in two years. That's one in four women. So really high mortality rates with hip fractures because of the things that follow it, but really emphasizes why it's so important to be strong as we age. So that's one of my main things is like, how do we age stronger? How do we get people to avoid frailty in a really graceful way? Yeah. You know, as you're talking about this, because I just recently had a knee surgery, which was a freak accident of a piece of cartilage just coming off my knee.
25:19Like I did nothing fun to do this. I probably did something in my 20s that like set me up for this. But I was as soon as I woke up from surgery, I like opened my eyes. And the first thing is that I'm lifting my legs. I'm doing all these exercises. I'm pulling, I'm moving my knee. And the nurses are like, no, no, no, no, no, no, no. We don't want you moving at all. And I'm like, you don't understand. You do not understand. And when I saw my physical therapist and my surgeon following up, they were like, I was telling him like how the nurses were telling me now. And they're like, so good that you did that.
25:52Like, we're so, and I'm like, yeah. And, and, you know, they're, they're trying to be encouraging to me. Cause I'm like, I have to keep working out. and they're like, no, you could take three weeks off. And I'm like, I'm 44. That's a lie. I can't, I can't take those three weeks off. But I think, um, you know, when you start to understand this stuff and you are start to understand like what the risk is, you can be empowered to take action. So if somebody is listening to this right now, often when we talk about how important muscle is, they think, oh, you have to be a bodybuilder. Like I, like I have to be like that extreme, right?
Read the full transcript
26:28Because that is what the algorithm on social media often serves up. Or you're in the age group where like Arnold Schwarzenegger was a thing in your life. What can women do that's an actual step daily to start preserving and building muscle mass? Okay, I love this question. Can I reverse a little bit though? I want to like set the stage in terms of, I think people don't understand women with exercise, I think is a really important topic. Do you know who exercises more men or women? I would assume it's women and doing cardio. I said the same exact thing. And the answer is that women exercise less than men at every single stage of life.
27:06Dang. I know. I don't know. See, I was a group fitness instructor. That's how I earned money through college. So all my classes are women. So I would just assume that like, of course, women are always at the gym, but wow. I thought the same thing. Women exercise less than men in every single stage of life. So if you look at women in their fifties to sixties, about 18 % of women meet the American Heart Association's recommendations for aerobic and resistance training. 18%. Which is also a very low bar. That's so low. Like it's a, it's a low bar of what the thing is. Yeah. What the requirement is, isn't like something extreme.
27:47It's 150 minutes of aerobic activity with two days of strength training and only 18 % of women, 50 to 60 meet that requirement. As we age, less and less people meet that requirement. So as we age every single decade after our teens, fewer and fewer percentage of people, both men and women will meet that requirement. And so when people are talking about, I don't want to overexercise, I'm like, don't worry about it. Like there's a group of people that are doing it, but it is such a small percentage of the population is over-exercising, the vast majority of people are under-exercising. And I'm like, come on, ladies, we got to at least meet these men.
28:25And so resistance training is so important for women. I think that it's gotten marketed to men and it's gotten marketed that you're going to get bulky and you're going to have these big muscles and women should more do Pilates or they should be on the treadmill or the elliptical. And it's done women such a disservice because women need resistance training in order to maintain health. I think people think that health is given to you. Health is earned. And this is one of the things that you have to do to earn that piece of health. Women have much higher rates of osteoporosis than men do. And the resistance training is one of the number one things to do to both prevent and treat osteoporosis.
29:06We also see that women who exercise regularly have a 22 % reduced risk for breast cancer. We see people that have higher grip strengths have a reduced risk for almost every single type of cancer, cardiovascular disease, dementia, you name it, it's on the list. But it's so, so important. And so when people come in and they come to me and they're doing one day at Orange Theory and then they're doing one day at Pilates and maybe they're doing a run kind of thing, I'm like, okay, that's great. Any movement is better than no movement at all. But we want to separate this into aerobic versus resistance training because you get totally different benefits from both of them.
29:44When we talk about resistance training, the plan should be really simple. And that's just start lifting weights and then write everything down. And then every week, make sure that you're increasing the weights you're lifting or the repetition so your volume is increasing. And just do it really methodically. But start slow, go low, but push yourself to a place that is getting harder and harder and harder. So I sit with all my concierge patients. I just did this yesterday. I take out my training log and I'm like, this is what it's going to look like. And we get into the weeds of it because it can be so simple and effective if you're doing it the right way.
30:18But most people, like I said, are just kind of throwing stuff at the wall, hoping something fits, doing all this random stuff versus having a progressive overload plan. Mm hmm. I am so glad we're having this conversation because I have shared with my audience multiple times that I call it how not to die protocol. And anytime I'm like, oh, I don't feel like working out. Do you feel like dying? No. Oh, I don't feel like going in my sauna. Like it's uncomfortable. It's sweaty. It's going to take time. Do you feel like dying? No. Okay. Like, and that's something that I check it out. But people have been like, that's morbid.
30:51That's not a good way to think about it. And I'm like, if you know the research, the research you just laid out, you can't unknow it. You can't unknow it. And when you look at what is coming down the pipeline, it's how I've always practiced medicine is I look at my patient and look at what their goals are right now. And I try to be predictive of what's going to try to take them out in the future. And that's where we have to focus. And for women, we know it's going to be osteoporosis, but cardiovascular disease. So we've got dementia. We're like 60 plus percent of that population, but we've got cardiovascular disease.
31:23So I want to talk to you about this concept because people often think like, I'll just take statins when I get there. What is more powerful in your clinical opinion when it comes to preventing heart disease, waiting for the statin or coming in with the lifestyle? Both. I don't choose between these two things because they're very different in my mind. These are two different things. So we know that ASCVD is preventable and is caused by elevated levels of apolipoprotein B containing particles like LDL is what we talk about the most. And if we take away that as a potential cause, so if we lower your apolipoprotein B, if you look at the PISA trial, they looked at LDL cholesterol levels at 50.
32:080 % of people in that trial had plaque formation in their arteries when their LDL was 50 or below. Study and play. Come together on a Windows 11 PC.

32:46And so I get all of my patients to have an LDL of around 50 to 60. I measure APOB. So again, I keep it around like the 55 for apoliboprotein B. And then that's that. And that may be using diet. So if somebody comes in and maybe their LDL is like 65 or 70, then we may be able to just reduce saturated fat in that person's diet. Reducing saturated fat in the diet gives you up to a 20 % reduction in LDL cholesterol levels. If you're eating virtually no saturated fat, you're not going to get a 20 % reduction. So this is people that have it in the diet and are able to take it out. Some people, if you come in and you're eating super high saturated fat, maybe you're on carnivore or keto, then you might be get a little bit bigger of a reduction there.
33:32But LDL and apolipoprotein B are so genetically linked that there's not a huge lifestyle component to them. And I think we really need to sit with that because people think they have control over everything. You can't change your ApoE for Alzheimer's. You don't have control over that. And you don't have total control of your LDL and apolipoprotein B. You have some, but not as much as you may hope and think. And so that's where medications come in is just to get people to that goal unless they're already really low to begin with. Now, the lifestyle things I said are separate because you get additional risk reductions with starting to exercise.
34:07So if you start to exercise, say you're exercising like 300 minutes a week, you get a 22 % reduction in your risk for coronary artery disease. That's incredible. I want to compare that to, though, the person that comes in with an LDL of 140 that we lowered their LDL to like 60, that person has an 85 plus percent reduction in their risk for heart disease. But it's not that they don't do the exercise because they should get another 20 % reduction, different mechanisms. So heart disease in terms of exercise, exercise on a regular basis reduces your blood pressure. We want that regardless of what your apolipoprotein B is.
34:44It helps with endothelial function and nitric oxide synthesis. We want that in terms of heart disease. And so I really push people. This isn't an either or kind of thing. It's a yes and. And sometimes we don't need meds. Like I said, I've got those people that come in and naturally their ApoB is 55 and they've got great genetics and then they don't need a medication. You just monitor. Yeah. And I think the other thing that people need to understand the context of this conversation is that your cholesterol, your blood pressure, everything may have been fine your whole life and you go into menopause.
35:17And now that's a different story. And I don't think women are being monitored enough and closely enough. I also had the experience of, um, so my second child was born at 40 and I, three months postpartum, I was like, I want to get a full workup. I want to check my thyroid. I want to check all this stuff. And in the first time in my life, I had elevated cholesterol. And my doctor was like, hold up, like, this is very concerning. She's like, what is going on here? And I was like, I'm postpartum and 40. I have no estrogen right now. And I'm breastfeeding. And she's like, wait, say more. And we got to have a whole conversation because she was like, I don't tip it.
35:54I'm not treating like I'm not doing any kind of menopause care with hormones. And I'm like, and it was a big aha moment for me of like, okay, wow, like this is foreshadowing. This is the things to come. And I think if any woman's listening to this, she's ever had high cholesterol in her life. She's had high blood pressure. She's had any cardiovascular risks. Pay attention to this information closely because once you're in menopause, all of this better be monitored and checked. And you can always go on estrogen therapy. That significantly helps, but it's certainly, I think there's a huge disservice being done to women right now with the whole menopause conversation always being about hormone therapy and I'm like, I've been prescribing for over 12 years.
36:33I'm a big fan. Okay. Love, love hormones when they're indicated. It is not enough. It is not enough. Yeah. Yeah. Yeah. If you, if you come in with an, uh, an LDL of like one 35, estrogen is not going to get you to optimal ranges. It may improve things, but it's not going to get you to optimal ranges from what I've seen in practice. Um, and then for the women who are younger than the perimenopausal menopausal age group. I have women come in in their twenties and thirties. If you come in in your twenties and thirties and you do all of this stuff, you can improve your health span and lifespan substantially because you're at a such young age.
37:11But what I've noticed is that these people come in, they have, I had one woman, 20 something years old, LDL of 135. And I'm like, has anyone else told you to go on medication? And she goes, no, I'm too young, they say. And that is something that you hear all of the time from other doctors, primary care is that, oh, their 10-year risk for cardiovascular disease is so low because they're so young, so we're not going to treat them now. That makes no sense to me at all because we know plaque formation in the arteries is all about how much time LDL has been exposed to those arteries to create damage.
37:48So why would you give it 10, 20 years to do damage when you can just stop it in its tracks at the age of 20 and never have exposure to those arteries. And so I treat women as soon as they come in in their 20s and men and get them to optimal ranges. So you don't have any plaque formation that's going to happen. I don't care if you're not going to die in 10 years. I'm like, yeah, I don't think she's going to die by the age of 35. I also don't want her to die by the age of 85 by a heart attack. And that's how you prevent it. So people will often present the argument that cholesterol does not matter if there is no inflammation in the body.
38:24What do you say to that? Yeah, that's a common one that goes around social media and it's just completely false. So you can have zero, like you can have completely normal CRP, completely normal sed rate levels, and you can still put plaque down in your arteries. It's not an essential component. Now, if you also have inflammation, could it speed things up? Absolutely. You know, that's why one of the reasons potentially that obesity can accelerate ASCVD, plaque formation. Um, but if you have a really low ApoB, you can't put plaque down. And so someone just commented on Instagram the other day, they're like, you're so reductionistic.
39:02It's not just about ApoB. I'm like, I'm not saying it is. I'm the person that's talking all about lifestyle, all about nutrition, all about exercise. And let's not forget about this piece that's causing a good chunk of this ASCVD and just treat it. I'm going to be honest. I think people who say that, it's because they don't actually have a deeper understanding of the research and the clinical experience that you do, that they think you can just out-eat it. You can just out-exercise it. And what I'm hearing from you, yes, nutrition, lifestyle, absolutely essential, absolutely important. But there are certain situations and definitely genetic carriers that it's not going to be enough for them.
39:39And I think it's really important for people to understand this is very individualized and nuanced. And unfortunately, no clickbait for the algorithm to want to share this with everyone. So we're going to need you guys to help us share it because if it's not sensational, if it's not like, oh, this one thing fixes everything, right? The algorithm doesn't serve it up. And it's such a disservice. I think we're going to have a study in the next 20 years of how social media training people, right? Because even doctors have to say things sensational. And then you try to get into the nuance. but how what the impact of social media was on people's health by not serving them the actual information that would have helped them totally agree totally agree yeah yeah it's something that we need to and it just starts with each one of us right but i get it too because i also have an instagram following yeah i mean i think everybody gets it these days who creates content and you're like this is so good and so educational and the algorithm's like we will show this to no one and And then you're just like, you say something like off the cuff.
40:41And then it's like, oh God, I didn't get to say all the nuance because it was a seven second clip. And that brings everybody. Everybody wants to see it. Let me ask you, what's your take on why people gain weight as they age? Some people say it's metabolism slowing. Some people say it's just your hormones changing. What's the big picture of what's happening? I did this in a talk and didn't go over well with the crowd. But so from the ages of 20 to 60, our metabolism does not slow. We know that now. So ages of 20 to 60, your metabolism stays the same. So when women come in in their 40s, 50s, or men, and they say, oh, I'm just getting older.
41:18My metabolism slows. I'm 45. I go, I'm so sorry. It's not because of that. Let's take that off the table and actually empower you with the things that are going to help because you can get great results for weight loss. um after the age of 60 we see we see minor declines in metabolism but you're looking at 0.7 percent per year little little bits not these huge drastic shifts that we think now what we do 100 percent know that changes as we age is what i talked about before which is exercise so every decade of life after your teens people both men and women are exercising less and less and less.
41:57By the age of 50, about 18 % of women are meeting those minimum requirements from the American Heart Association for exercise. And so I think that it's two-part. I think that it is, we are not exercising enough. And I think that we are eating more and there's hormonal shifts that can contribute to increase cravings and appetite. And there's medications that can increase your appetite. And the fact that we live in a world that has so much ultra-processed food at every single corner, the accessibility, I think plays a role in it as well. But I think that it's, those are the things that we should be focused on versus, you know, trying to find like this, like hidden kind of thing.
42:40Yeah. I would also add that, you know, we know as estrogen goes down, we can accumulate visceral adiposity that can lead to increased inflammation, insulin resistance, and that can shift our metabolic health in a negative way. And for people listening, yes, estrogen therapy is an option, but we also know what moves the needle there. Higher fiber diet, less added sugar, which is what you were talking about with the ultra processed food. Ultra processed food is like, it's like eating styrofoam sometimes, right? But it tastes better where you're just like, you're getting no fiber, no nutrients, nothing from it.
43:18And I'm not here to be like, never eat ultra processed food because it's just not the society that we live in, but it is to reflect on that as well. Because I think that you're right as well, that hormones shift cravings, also shifts satiety. So your sense of feeling full. So there's a lot of factors going on here. But it's also, I think, why women feel frustrated when people are like, just eat less and move more. And it's like, that's so easy to say. You're acting like I, it's a willpower issue when it's like, I've got a whole physiological shifts happening here that's working against me. Totally.
43:55And maybe you're a mom of three and you're running to soccer practice and juggling your own career. So I'm not saying any of these things are easy, but I wouldn't put my time towards like some of the kooky things out there for weight loss. I would put my time towards how can I make sure that I can have a better diet. And maybe I do need to go on hormone replacement therapy to help with my mood or, you know, whatever it is kind of thing and get all the foundations in place. But absolutely, estrogen dropping reshifts fat distribution, right? So hormone replacement therapy doesn't cause weight loss, but it can change fat distribution in the body away from the midsection down towards the hips, butt, and thighs where it doesn't increase the cardiovascular disease risk as much.
44:41Good point. Yeah. I want to ask you, what's one thing about longevity that you wish people would stop obsessing over? There's so many things. It's the quick fixes. It's the people that are, you know, they're doing the greens powders and the colostrum, but they're borderline sarcopenic. It's, you know, going in for the NAD drip when you haven't exercised in two years, or, you know, it's like doing, it's the minors over the majors. It's like the people and the influencers that are focusing on these minor things that may have zero evidence or very little versus the major things that are going to give you 90 plus percent of the actual effects.
45:28I want to ask you about GLP-1s because you said quick fixes. A lot of people see that as a quick fix. However, in the context of the conversation, we've been talking about weight loss, but now we're starting to see really promising trials for cardiovascular disease coming out and starting to look at Alzheimer's and dementia patients as well. So from a longevity perspective, we're starting to see, there's the people who, right, we started with GLV-1s because they needed weight loss support or diabetic, but we're starting to see a lot more people using them at lower doses because of the potential cardiovascular.
46:04And the cardiovascular is actually established. So I won't say potential, potential for the individual, but the cardiovascular outcomes are established. The brain is the one that we're like still waiting for some more robust data to understand that. But what are your thoughts? And kidney function we're seeing as well. Yeah, kidney function. I think GLP-1s have a potential to be a geroprotective, meaning like a longevity drug. I think it's a potential. So we need to start looking at them more in normal weight individuals. And are we seeing health outcomes in those individuals? And can we use them in normal weight individuals that doesn't induce osteoporosis, like too much weight loss, right?
46:40Thank you for saying it. Is there somewhere like a happy medium where we can get some of these potential effects without negative side effects for those normal weight or healthy weight individuals? So it's one of the ones I'm really excited about in terms of potential geroprotectives. Would I go on one right now myself with that in mind? Absolutely not. Like my risk of osteoporosis, sarcopenia, if I lost weight or muscle, way outweighs potential benefits. And so we got to figure out like dosing what that looks like. and if we're getting the same effects with normal weight people as people who are overweight.
47:15But I use GLP-1s in my practice all the time with people where it's indicated and going to be helpful. And in conjunction with resistance training and all the things that we've been talking about, the outcomes are incredible. And you mentioned something before where it's like, well, of course, just eat less, exercise more. Do you hear that? Sounds like breakfast is ready. Because Quaker's coming in hot with morning nutrition, 100 % whole grain oats, and a good source of fiber to fuel the rhythm of your morning and kickstart your day. And that sounds absolutely delicious. Fuel to start whatever's next.
47:58Quaker, official sponsor of FIFA World Cup 26.
48:04There's a lot of people who have been trying that for a long time and they lose 10 pounds and then they gain the 10 pounds. They lose 20 pounds. They regain it. And this is a huge step for obesity medicine because we're seeing people lose the weight, lose more weight, keep it off. And their mental health is changing. So the number of people that come into my practice and they've only lost like the first 10 pounds and they've got 100 plus to lose. But they're like, I've had people crying in tears just being like, I have my life back because they're not thinking about food 90 % of the day. So there's so many aspects to obesity and there's a huge obesity bias in our country.
48:44And we really have to view it as more of a disease state that has many different layers to it. One of them is mental, emotional and appetite regulation and all this other stuff. I appreciate you though, bringing up the muscle loss, the sarcopenia and the osteoporosis risk because I had people asking me to do a GLP-1 episode and talking about the science of cardiovascular disease and potential benefits and pairing it with HRT and how all of that works. Something I said in that episode was, if you lose weight and it is muscle, you are not healthier, you are just smaller. The number of women I had, right, who were like, I've been going to a med spa, getting these GLP-1s, and I am losing muscle.
49:33Like it never occurred to me that smaller doesn't mean healthier because the healthcare practitioner prescribing this didn't actually do a, you know, body analysis, didn't do a Dexomni, didn't do any of these things to make sure that like, this was the best move for me. And so I just really want to underlie what you're saying, because I think, you know, it goes back to what the exercise piece of what you were saying of women being told to do cardio, do Pilates, right? We're constantly told to shrink ourselves and that's been packaged as health. But from this conversation for people to understand, I want you all to go rewind and listen to what you said about sarcopenia and osteoporosis risk because you're absolutely right.
50:15Shrinking your body isn't going to necessarily mean you're healthier and it may put you at risk for the things that we are actually dying of. Yeah. Yeah. And I'll add one more layered to that where if you have somebody who's indicated for these GLP-1s, they're overweight, they're obese, they have weight to lose, it's affecting their metabolic health. The weight loss percentage from lean tissue versus fat mass is no different than if they were to do lifestyle changes. So we see the same amount of muscle mass loss with GLP-1s as we do with lifestyle changes throughout the trials, which is about like 25-ish percent of the weight loss will be from muscle mass.
50:52I measure that in all my patients. And so I just had somebody that come in, oh, your percentage of muscle mass loss versus fat loss is a little higher than I'd like to see it. Like, let's really focus on the resistance training. But you, you will always lose muscle when you lose weight. That's just where my concern comes in with normal weight people that we're not trying to lose weight. We don't want muscle losses in them. Yeah. Yeah. Let me ask you, if you could challenge the audience to like over the next seven days, do this one simple thing to improve your health and longevity, what would you challenge people to do?
51:26Oh, does it have to make them feel different in seven days? No, but it can start changing their life in seven days because habits take time to form. We all think we can just like start doing something the next day and then we'll be with it. I want you to start logging your workouts. This is one of the things that I think has made the biggest shift for my patients is log your workouts in terms of how much weight you're lifting, how many reps and how many sets you're doing and create a program where every week you're just increasing that number. Do the same exact workouts three days a week. But that one change I have seen make the biggest difference in people's body composition, risk for metabolic diseases, all this stuff, because it ensures a progressive overloading of the muscle and you'll get results.
52:13So many people are just like, just exercising randomly, which is great. That's better than nothing. But if you're gonna do one thing, log. That will change it in seven days. You will absolutely start changing in seven days. Let me ask you, what does, knowing what you know about longevity, what does your fitness routine look like through the week? So I do three days of resistance training. I log everything. I've got a spreadsheet and it improves every most weeks. and then I do at least two runs during the week with my little puppy and so we do a slow run for 40 minutes in the last 20 minutes I do a vo2 max workout which is sprint intervals so like all out for 20 minutes on and off a minute ish and then I play tennis twice a week and I usually go for at least one hike and that's kind of like the backbones and I walk my dog twice a day for at least like an hour each time.
53:05So I move a ton. Tennis is one of the big longevity hacks when it comes to exercise. So people playing pickleball as well tends to be so, so good for the brain. I want to do some rapid fire questions like with protocols that are all longevity focused with you. So I'm going to say something and you answer like top of mind. What do you think? Great. What would you recommend to people? So if someone has weak grip strength. Increase total body strength. You don't have to just increase your grip strength. Research is more about your total body strength. So lift weights. If someone has a family history of heart disease.
53:46Optimize your ApoB. Get it to like 50 to 60. Make sure your blood pressure is perfect. exercise eat a Mediterranean diet don't smoke avoid alcohol sleep seven hours you're off to at least seven hours please if someone has gained weight in midlife caloric restriction number one get about 1.8 grams per kilogram of body weight of protein if you're a woman 25 grams of protein or 25 grams of fiber for your man like 35 grams of fiber per day and just start moving your body more and more. There are people who say more is better with fiber. You just said 25 grams of fiber. There are people out there saying, no women, you need to get 35 to 50 grams of fiber.
54:32What are your thoughts on that? I think you need to start low, go slow with fiber, or you'll never eat it again because it'll cause intense gastrointestinal issues. So most people, I do diet logs with all my patients. They're coming in at around 10 grams of fiber, seven grams of fiber. If you went up to 35 from there, you would kill me. so you want to gradually increase just keep adding servings but 25 grams for women is the minimum and then it's um it's based on how much food you consume too so if you're a woman who's 170 pounds you're closer to 35 grams and yeah more may be better i don't think that there's really an upper limit for vegetables unless you know some tiktokers gonna show me that they died because they ate like 2 million pounds because people do it it's like whenever people are like i can't eat broccoli because I have thyroid disease.
55:18And I'm like, you know, your gut would stop you before you could eat the amount of broccoli it would take to affect your thyroid. Like we're talking about pounds of raw, raw broccoli. Your gut will say no before your thyroid even knows what's happening. Someone's going to do it. Someone's going to do it now and they're going to be sad. Don't do it. What do you say to someone who's like, I cannot get quality sleep? uh i've been there cognitive behavioral therapy for insomnia love it google it find a practitioner and you will send me a thank you note and some flowers because that shit works yes i i agree when you're like restriction yeah yeah when you're like i've done all the sleep hygiene things and they don't work oh cbdi like works like a charm if someone's worried about dementia Um, top four risk factors for dementia that accounts for 30 % of global dementia cases is going to be number one, um, a sedentary lifestyle.
56:18So exercise hearing loss, make sure that you are checking your hearing throughout life. And if something happens, you need to get a hearing aid to fix it. Um, sedentary lifestyle, uh, blood pressure. So high blood pressure, maintaining a normal blood pressure is super important. And then education level. So continuing to learn things, learn a new language, um, you know, listen to podcasts that stimulate you mentally, have interesting conversations. Those are the top four, right after that LDL levels that are high in midlife three X the risk for dementia. So get your LDL, your APOB levels lower.
56:55And then it's all the things that we know, avoid smoking, you know, eat good food, Mediterranean diet for sure. Yada, yada, yada. Yeah. Mediterranean diet is always winning. And I love that you bring up the hearing loss and people, yes, it is true that magnesium has been shown to help with hearing loss. However, an audiologist is the person to see because you're absolutely right. If your hearing is going, get a hearing aid. Even if you want to try the magnesium and try other things, no one says you have to do one or the other. You can do both. And I think it's a great way to marry those things.
57:33If you had to make a bold prediction, what do you think we will know five years from now when it comes to longevity? Interesting. I think we'll have a sense of biomarkers for longevity. Like right now, I think some of the better ones are VO2 max, your appendicular lean mass, how much muscle you have on your arms and legs. things like A1C, fasting insulin, just in terms of like risk factors for the big things. But I think that we may know more about like biomarkers for actual longevity. We have these like biological clocks now that people will say, what's your biological age versus your chronological age?
58:11And right now they're trash. Like I wouldn't even touch them, at least the direct to consumer ones. But I think like those may be in a good spot or something like that in a good spot that we have more easy ways to measure longevity. And then I'm guessing like some better like gerotherapeutics where, yeah, maybe we have figured out the GLP-1 thing for extending lifespan or rapamycin has more information around it, or we know about maybe some supplements that are, you know, kind of promising. So I think we'll have more information on those right now because I don't think we have the information right now.

From the publisher
Midlife weight gain is often blamed on a “slowing metabolism.” But the science tells a different story.
Between ages 20 and 60, your metabolism barely changes. What does change? Muscle mass. Exercise habits. Hormonal signaling. Cardiovascular risk. And increasingly, the conversation around GLP-1 medications like Ozempic.
In this episode, we unpack the real drivers of midlife weight gain, the surprising data on muscle loss and mortality, the nuanced role of GLP-1 drugs in long-term health, and what actually improves lifespan and healthspan.
If you’ve wondered:
Is my metabolism broken?
Is Ozempic helping or hurting long term?
Why is muscle suddenly such a big deal?
What actually prevents heart disease and dementia?
This episode connects the dots.
