As anyone who’s gone on a diet knows, once you lose some weight, it gets harder to lose more. The “eat less, move more” mantra, as simple as it sounds, doesn’t help us deal with our bodies’ metabolic reality: As we shed pounds, we get even hungrier and our metabolism slows down.
But findings from a new study I led with my colleague Cara Ebbeling suggests that what we eat — not just how much — has a substantial effect on our metabolism and thus how much weight we gain or lose.
People have a hard time believing that weight control isn’t just a matter of calories eaten and calories burned. But there is an alternate hypothesis about obesity, which is what my group studies. The carbohydrate-insulin model argues that overeating isn’t the underlying cause of long-term weight gain. Instead, it’s the biological process of gaining weight that causes us to overeat.
