Dr. Jason Fung Breaks the "Counting Calories" Weight Loss Myth and What You Should Be Doing Instead

Your body could simply decide to burn 500 less, and you will not lose body fat. So, it's simply false to say 'If you cut 500 calories a day down, you will lose a pound of body fat a week.' It's actually not true in any way, shape, or form.

It's not the number of calories; it's what your body does with those calories.

[Obesity] leads to type 2 diabetes, which is a huge risk factor, not only for kidney disease but for heart attacks and strokes and cancer, and it's a leading cause of blindness and amputations and diabetic infections and all kinds of bad things.

You can't eat all the time because, again, it's a cycle between feeding and fasting. That's what we're supposed to do. If you don't give your body time to burn off all those calories that it's taking in, which means the fasting period, you're going to, overall, gain weight.

Insulin, what it does is it tells your body to store fat, but it also turns off fat burning.
