Help! I can't get back to my body's set point! I grew up fat. I was almost 17, 200+lbs and super weak. My body should be desperately trying to hold on to every calorie it takes in to return to its set point of 200ish, since the set point is always your highest weight. What am I doing wrong?! I'm 30, 165lbs, and muscular. Why won't my body do what it's naturally supposed to and return to its set point?
