Can someone explain to me how the starvation mode theory works??

Question

ok i got a friend that use to be anorexic and supposely when people are anorexic and they decide to eat again their body will store every calorie as fat and therefore that will make them fat because of the starvation mode theory!! i live with my friend and i see everything she eats, and now she eats healthy foods. She has been eating normal for 2 years and she's not anorexic anymore but she is skinny not like she use to be but now she's got a pretty good slim body. so i don't think the starvation mode thing is real cause than she would have got fat!!! if you think the starvation mode theory is real please tell me how come my friend is not fat!! btw before my friend became anorexic she wasn't fat just a little bit chunky!

Answer 1

You lose weight during starvation, its just the your body burns everything BUT the fat to keep you going. So starve yourself for a week and you loose 10lbs, but none of it would be fat
