> And the very act of gaining weight causes your body's set point to move up, because of how weight gain affects your hormones. Unfortunately the set point is pretty sticky, and once it moves up, it does not like to move back down, in part because for most of animal history, weight loss is a sign of starvation. Kind of, but increasing doesn't go indefinitely either. People have multiple "set points", not one moveable one, long known among people intentionally increasing their weight as "plateaus".
