Okay, so imagine one pound of your own fatty flesh. So if you burn that amount of flesh that sounds kind of you know weird, but if you were to convert that into energy, you would get about 3500 calories, which is quite a lot of energy. That'S me talking with dr. Carson, Chow and MIT trained physicist and mathematician, and he's explaining to me why we should care how much energy fat has in order for you to live and function. You need to burn energy to like keep your heart, beating all your your organs going and also to move around, but energy doesn't come for free. So if you're not consuming enough calories, you're gon na burn that energy with your own fat and so a lot of diet books like to teach people this rule. But the problem is it's wrong and here's. Why so, let's say I eat 500 calories less a day. So after one week it would be 3500 calories and I would lose a pound right because I'd have to burn yeah. If I stayed on this diet for a year, I would burn through 52 pounds be great. If you keep taking this thing, while after two years, I'd lose 104 and after 10 years, I'd lose 500 pounds. You know so obviously at some point, this rule is gon na break down. It will actually break down before you get to a year so to understand the real math behind losing weight. Dr
Chow wanted me to imagine a leaky bucket. You have some water in the bucket and that's the amount of body, fat or tissue in your body and the leak represents the rate at which you're burning energy. What, in reality, what you're doing is you're adding water at the top? That'S like eating food and when you're in steady-state the amount of water you add at the top, exactly balances the amount of water you lose at the bottom. If you're pouring in more water than it's leaking, then you're gon na gain weight. Now, if you think about the physics of a leaky bucket, the more water that you pour into the bucket the faster it's gon na leak, so your leak rate scales with how big you are - and this is a well-known fact - that the larger you are the more Energy, you burn you're going to burn more energy because it takes more energy just to move a larger mass. You have more tissue and just to keep that tissue going. It takes more energy. Congratulations. You have a new, steady state, but let's say you don't want to stay this large person that you've become well. The opposite is true as well. You could pour in a lot less water than you're leaking, but, as you start to lose weight, you start to get smaller and you burn less energy. You start to metabolically, adapt to your new diet and so you're never going to lose weight at one constant rate. It'S always going to curve from one steady-state down to another, which means when you go on a diet. The 3500 calorie rule is the wrong rule. There'S a new rule, wait for it. The new rule is for every 10 calories. You eat less. You will lose a pound, but it will take you about 3 years or more to see that the full effect of your diet, which is still pretty good you just see all you have to do - is eat 100 calories less. You lose 10 pounds, it's like a can of coke, so you should expect the diet to be extremely slow right, but nobody wants a slow diet. We all want to lose 20 pounds for this summer. What'S wrong with just focusing on losing weight rapidly. The problem is once they're down at that new weight. They have to be vigilant for the rest of their life, because losing weight is slow, gaining weight is also slow, but it slowly creep up and then two three years later bang and hit something they're back to where they were so. The mathematically approved rule for weight loss for every 10 calories. I don't eat a day, I'll eventually lose one full pound, which means changing your steady-state is a marathon and not a sprint, hey guys. This is Todd thanks so much for watching.
