It might not be as simple as that. Some of us keep eating and remain cold while turning lethargic, constipated and overweight. it’s no fun to keep stuffing one’s face while the stomach is overloaded and the body is breaking out in hives/inflammation from the inability to handle the food. And we still need to be fit to live our lives. Not everyone can take time off to do this. I had to moderate my eating in order to stay within the upper normal weight range and keep my energy up to get the things done, I need to do. But I am breaking out in hives from having introduced so much sugar, dairy etc. and it’s not fun. Eat more isn’t the answer I can apply, sadly.
