Other studies suggest that levels of testosterone may be linked to cholesterol and body fat in men. In an earlier Vera Slim study conducted in 2008 in Ghent University Hospital, Belgium, researchers concluded that testosterone and body fat may be related to one another because both are partially controlled by the same set of genes. Evidence of this was shown by the simultaneous occurrence of low testosterone levels and high body fat percentage in their subjects. Other research also suggests that decreasing testosterone levels are correlated with elevating cholesterol levels.
