After somewhere between three and five hours, your body stops processing its last meal. There's nothing left to absorb, so insulin levels naturally decrease. Then, somewhere between eight and 12 hours after that last meal, your body starts burning stored fat. (Why don't you start burning fat sooner? Biology is sometimes a pain in the ass; it's like our bodies will do anything to hang on to fat.)
In our eat-and-run, massive-portion-sized culture, maintaining a healthy weight can be tough—and losing weight, even tougher. If you’ve tried and failed to lose weight before, you may believe that diets don’t work for you. You’re probably right: some diets don’t work at all and none of them work for everyone—our bodies often respond differently to different foods. But while there’s no easy fix to losing weight, there are plenty of steps you can take to develop a healthier relationship with food, curb emotional triggers to overeating, and achieve lasting weight-loss success.
