Visceral fat is where the story gets less obvious.
It sits around the internal organs. And a new analysis of 4,948 U.S. men found it was strongly linked to lower total testosterone.
Men with high visceral fat had 33% to 36% lower total T, on average, than men in the same BMI category with low visceral fat.
That’s why BMI alone doesn’t tell the whole story. It’s one piece of the picture.
