Never mind, Devorah. I know exactly what you're talking about. However, this guy is 30 and naturally thin, so he knows more than we do. He may be like my son, who lives on stuff like frozen pizza and Mountain Dew and is extremely thin, but more than likely, he'll eventually end up overweight at some point and will have no idea how it happened. He will cut calories and exercise more but will not be able to keep it up, and he will realize, perhaps, that he was full of it. But that will be a decade or two from now.
