Fat isn’t necessarily just about CICO. Someone might have a disorder causing them to store more fat than, for example, build muscle. You might have a thyroid disorder causing you to feel lethargic despite the fact that you ate a BMR level of calories, so you end up storing the remaining energy as fat. Not even getting into the variety of ways human behavior is illogical and can’t reasonably be answered with “just eat less.” Treatment for eating disorders is not like that.
Do you have a way that a person can gain weight at a calorie deficit? I acknowledged already that people can have a lot of physical changes that cause them to overeat but at the end of the day overeating is the problem
