1030 How To Prevent Cancer With Your Food & Fasting w/Jason Fung

If you think about the number of diseases that you can make better—heart attack; stroke; cancer; diabetes, which is the leading cause of blindness, of kidney disease, [and] of amputations—the secret to managing all of these things is not more medicine and surgery; it's less. It's actually within our grasp because fasting is free to every single person on Earth.

When you actually look at the science of what happens during fasting, it's actually one of the best things you can do for yourself from both the mental standpoint and a physiologic standpoint, assuming, of course, you're not malnourished.

In the fed state, insulin goes up, you're storing calories or body fat. In the fasted state, you're not eating, your insulin is dropping, and you're using calories. So you're one or the other—you can't do both at the same time.

High insulin, for example, blocks fat-burning. You can't burn your fat stores because your body's like 'The instruction that I'm getting is to store energy, not use energy. I want to keep my stored energy for when there's a time that there's no food.'

The biggest one, of course, is tobacco smoke. So, that's sort of, by far and away, the biggest contributor to cancer.
