>Hi Sam

>I hope the question is serious.

>Swimmers actually do have a higher body fat level than runner or cyclists.

>It's a know fact that swimmers are generally "big eaters".

>See http://www.sportsci.org/news/compeat/fat.html for additional information about the "body fat mystery" swimmers are experiencing.

>Another theory although not proved is, that the body is protecting himself from loosing body temperature by building up the body fat level (sounds convincing to me).

>BTW: I don't know how old your nephew is, but if he's in his teens and doesn't have problems with his weight (nowadays that's often the case..), I don't recommend dieting unless supervised by a professional. It's better to eat "healthy" food (I consider fast food as not healthy).


Thanks Bruno.
