In order for me to lose weight, I have to eat less than 1,000 calories a day. And that's with exercise, which I already do. I have been to countless doctors over at least ten years, and the official cause it, "That's just the way your body is." I had an eating disorder for years, and that may have contributed. I eat ridiculously clean and healthy, basically Paleo, and have for years. If I ate like the average person, I'd be 100 pounds overweight. I currently eat about 1,200 calories a day just to maintain being 20 pounds overweight. I have to weigh and measure everything, just to stay where I am. If someone has never had food issues before, it is really easy to sit and judge. Do you tell people with anorexia to just eat a burger? Because it's kind of the same thing.
