@londonmum People really don't understand this basic concept. I guarantee you his wife eats a normal average of calories for someone her size over the course of a week. Unless she's insanely active or something.
@cfitz Other than some water weight these things mostly effect your appetite, not your metabolism. I have a very hard time believing this person was eating the same amount of calories unless they had significant changes in activity levels.
@veroch So many skinny people try to say they just have a fast metabolism, meanwhile they're never finishing a meal lol. I don't think they realize how much some people eat. It's just like how fat people say they don't even eat that much.
