Lean Mass and Longevity

Next article again with a DEXA scan. For every one pound of fat loss there was a half a pound of fat free mass, visceral fat which is the dangerous fat that's inside your guts that went down 27%, total fat down 20% and fat free mass went down 9.7%. When somebody loses weight they're going to have less circulating blood volume. Their bones won't weigh quite as much, their muscle skeletal system won't weigh quite as much because it's not carrying so much weight. But it went down much less than their fat mass so their lean mass percentage improved. And there's a lot of like knowledge now that lean mass is a predictor of longevity and health but it's really lean mass as a percentage of your body weight, not total lean mass. So in other words a person that's relatively small could have just as much longevity as somebody that's taller and bigger but it's based on their lean body mass as a percentage of their total weight.
