We might find evidence too of vitamin or other mineral deficiencies being connected to obesity by virtue of the fact that most obese people simply don't make an effort to eat a healthy, well rounded diet. It doesn't necessarily follow that consuming any particular mineral beyond the body's requirements will accelerate fat loss. Maybe there's a link and maybe there's not, but just be aware of the error of placing more stock in a spurious correlation than you should, as well as the potential danger of overconsuming vitamins or minerals through supplementation.
Candi, I see you made a similar point in the egg thread. Good lad.
