three and a half years ago, i made one of the best decisions of my life. as my new yearamp。39。s resolution, i gave up dieting, stopped worrying about my weight, and learned to eat mindfully. now i eat whenever iamp。39。m hungry, and iamp。39。ve lost 10 pounds.
this was me at age 13, when i started my first diet. i look at that picture now, and i think, you did not need a diet, you needed a fashion consult.

your brain also has its own sense of what you should weigh, no matter what you consciously believe. this is called your set point, but thatamp。39。s a misleading term, because itamp。39。s actually a range of about 10 or 15 pounds. you can use lifestyle choices to move your weight up and down within that range, but itamp。39。s much, much harder to stay outside of it. the hypothalamus, the part of the brain that regulates body weight, there are more than a dozen chemical signals in the brain that tell your body to gain weight, more than another dozen that tell your body to los
