To appreciate how your body works to maintain your weight, it helps to understand a little bit about the internal controls that govern this complex process. These controls include a tiny structure deep within the brain, nerves that run between the brain and the stomach, and a host of hormones. Central to this entire system is your metabolic rate, which automatically adjusts in an effort to maintain your set point. (But, as you’ll learn later, external forces can override these internal controls.)
