Coming up on this mini episode of the doctor's pharmacy.

Such a pervasive myth that weight gain is all about calories and calories out.

Why did we get it so wrong? And how do we not sort of stay stuck in this idea that all calories

Although many scientists and nutrition experts would have us believe that eating and gaining weight

excess carbs and they're not really turned into fat. That's a difficult process for your body to do

with its energy expense and it doesn't do it that much. But what your body does is make sure you burn
