No, being middle aged doesn't lead to a high body fat percentage. Being a father doesn't lead to a high body fat percentage. Being a MOTHER and growing a human doesn't lead to high body fat percentages, so how do you figure that it's to "be expected" that someone who is a father and middle aged has high body fat? No excuses.  It's bad enough when women blame fat on babies but it's a million times more infuriating when a man claims he looks pregnant or has a gut because his wife once had a child. Just stop.
