Episode 131 - Interview with Dr. Jason Fung: Calorie Restriction vs. Fasting, Hormonal Benefits of Fasting and Reversing Type II Diabetes

Some foods are more fattening than other foods. And this is just common sense. Like, you ask your grandmother. She's like, 'Yes, cookies are more fattening than eggs.' That's just common sense. Or if cookies are more fattening than broccoli. Who gets fat eating broccoli? Like, nobody ever in the history of mankind.

If we had to make sure that we got up and put a muffin in our mouth within 30 minutes, we wouldn't be here as a species.

Our entire body runs on hormones. That is, if you take two foods—one cookies and one is, say, salmon—the minute you put that in your mouth, your body responds to it completely differently.

Why do you need to constantly put calories into you if you have a huge store of calories?

Fasting is not only a way of eating fewer calories ... But it's also a way to reduce your insulin ... If you don't eat, your insulin is going to go down.

So remember, if insulin is high, you're giving your body instructions to store calories. If your insulin is low, you're giving your body instructions to burn calories.

It's just better to eat natural foods. If you eat natural foods, your body will know how to handle it, including telling you when to stop.

The people who had been talking about calories, calories, calories have been busy denying that it had any relevance to human physiology. It's like, the human physiology runs on hormones. Everything runs on hormones.

If you rely on willpower, you're simply going to fail, because you're going to expend it. And then the minute... you stop expending that willpower, you fall into your bad routines, and you lose all of your progress.
