Q: do you think a person who has a body composition of 16% and who has very little visceral fatis healthier than a person who has a BC of 11% but who has a significant amount of visceral fat.Visceral fat is a major factor in getting certain diseases.

A: This is probably a question better answered by a doctor, but from my point of view I see no reason why the 11% BF person would have more visceral fat than the 16% BF person all other things being equal. If you had 16% BF at one point and after some time, through healthy diet and exercise, dropped to 11% BF, I think it's very very unlikely that at the same time your visceral fat would have increased.

If we're talking about an 11% BF person who is, for whatever reasons, more predisposed to having health problems and that is evidenced by high visceral fat, then no, I would not call him healthier than an average problem-free 16% BF person. But I think that's comparing apples to oranges. All other things being equal, I don't see how lower overall body fat can result in higher visceral fat concentrations. However I am not a doctor either :)
