Make sure you're following and stay tuned to this episode of The Daily Motivation Show.

0:38Hi, my name is Lewis Howes and welcome to The Daily Motivation Show.

0:49I love to eat too, but I don't want to beat myself up just so I can eat more. So that was the thought experiment. And then if you reverse it, you go, well, if that's the case, what's the least amount of food I can eat and maintain my body mass, maintain my energy, not get sick, and most importantly, not be hungry? And it turns out it's about 30 % fewer calories than I used to eat. Wow. Yeah. So I learned within the last 10 years, I've learned, you know, to sort of halfway through a meal, ask myself just sort of subconsciously, am I really hungry for the next bite? Not am I full, not am I whatever, but am I truly hungry for the next bite?

1:29And if I'm not, I'm okay pushing the plate away, wrapping it up, throwing it away, giving away, whatever. Because I know there's food wherever I want, whenever I want. So it's not like I'm trying to pack on the… Trying to stuff it, yeah. Yeah. What if you just enjoy it? Well, if you enjoy it, keep going. Yeah. But a lot of times you get into that space where you go, you know, am I eating this because… It's still there. Because it's still there. Yeah. Am I truly eating it because I enjoy it or am I, you know, like I used to, I had a habit of one half gallon of ice cream a night for five years. That sounds amazing.

2:06It was amazing. And it was in my training days. So I burned it all off, never gained any weight. I actually weighed probably 20 pounds less than I weigh now. Wow. Yeah. But it was a half gallon of ice cream every night. And it was like, I couldn't only eat a pint. It was like a pint of ice cream. Don't even, like, why am I going to get started on that? I'm just going to, you know, rip your throat off and want more, you know, it's whatever. Rip your head off. So I would, and if it was 10 o 'clock at night and I didn't have any ice cream in the house, I'd get in the car and drive and get some. It was like a real addiction, a real sugar addiction.

2:38Clearly, I got rid of that. But it was, you know, I wonder at times whether I had described this, it's a half gallon is my dose of ice cream. And even though I could have satisfied myself with a pint or a half a pint, because it was there, because I could eat it and I could get away with it, that became my dose. It's like people have a bag of potato chips. You have a little individual serving size of potato chips. The whole bag. And you have one this big. There's still, to some people, each one is an individual serving size. It is. It's tough to just have a few chips in the big bags. So what are these, you know, for athletes listening or for people that want to get back in their athletic ways?

3:20You know, I used to be a professional athlete and I'm still, I consider myself an athlete. You've got nine pieces of primal advice for athletes. But I think a lot of entrepreneurs could live this way too. And still like be better entrepreneurs, be more productive, have better relationships, be sharper, all these different things. I think everything you do to be a better athlete makes you a better entrepreneur. Absolutely. Absolutely. Absolutely. But you talk about adequate sleep. And this is something I've been talking about a lot lately on my podcast and bringing out different sleep experts. But why just emphasize is sleep important for you?

3:50I mean, sleep is when the body renews and regenerates, repairs itself. It's when a lot of the neural networking happens to overlook sleep and to think, well, you know, I can sleep when I'm dead. Well, you know, that just is so such faulty logic. Yeah. It's so critical and so important. I try to get eight hours a night myself. If I get less than six for some reason, I feel it. I know it. I try to make up for it. I try not to let that happen. I try not to schedule late nights because I wake up at the same time pretty much every morning. So if I... 6 a.m. wake up or... Yeah, 6.30, 6 a.m., 6.30. But if I were to go to bed at one, I'd still wake up at my normal time.

4:28So I have to really force myself to – not force myself because I'm tired at the end of the day. And I have this whole wind-down process. What is that? So my wife and I, we'll watch some – we'll do some television after dinner. We'll catch up on – we'll do some binge-watching, catching up of whatever the latest series was. But around 10, we'll break – I have a pool in my backyard and a jacuzzi. So I go in. The pool's unheated. So in the wintertime, it might be in the 50s. I'll walk into the pool and hang out there for a couple of minutes and get really, really cold. But not to the point of shivering.

5:06It's kind of a process in and of itself. Then I'll get in the jacuzzi. So my wife and I will hang out in the jacuzzi. We'll just recap what the day's events were. We turn off all the lights in the house. We have a fire pit out there. So there's a real sort of a primal caveman kind of thing to that. then I'll just finish off with another minute in the cold and towel off and go up to bed and I sleep like a baby as a result of that wow, the hot cold therapy yeah, the hot cold therapy and that's kind of how I wind my day down and that prepares me to sleep brings my body temperature down which is, you know, they say that you should have your lower body temperature to sleep better we keep the room around 67 we have blackout curtains so it's a real cool sleeping environment it.

5:52Yes. I always like to keep it cold. Yeah. Yeah. Okay. And so if you do like a cold shower before bed, you think that's a good thing? I think it's a good thing. Yeah. It'll help you sleep better. I think so. Try it. I mean, you can't hurt.

"Am I really hungry for the next bite? Not am I full, not am I whatever, but am I truly hungry for the next bite?" - Mark Sisson

Mark Sisson used to demolish a half gallon of ice cream every single night for five years straight. Not a pint, not a few scoops - the entire half gallon, like clockwork. If it was 10 PM and his freezer was empty, he'd drive to the store to get his fix. This wasn't just a sweet tooth; this was a full-blown sugar addiction that controlled his evenings. The breakthrough came when he flipped his entire approach to food: instead of asking "how much can I eat and get away with it," he started asking "what's the least amount I can eat while maintaining my energy and never feeling hungry?" That simple shift led him to discover he could thrive on 30% fewer calories than before, all by asking himself one question halfway through every meal.

But Mark's optimization didn't stop at food - he completely transformed his sleep game too. Every night, he follows the same ritual: after dinner and some TV with his wife, he walks into his unheated pool (even when it's in the 50s), gets really cold without shivering, then jumps into the hot jacuzzi to recap the day. He finishes with another minute in the cold, towels off, and sleeps like a baby in a 67-degree room with blackout curtains. This isn't just about sleep hygiene - it's about recognizing that your body has signals for everything, from hunger to rest, and learning to actually listen to them instead of fighting against them.
