eli5: What is actually causing the “beer belly” appearance?

909 viewsBiologyOther

I was wondering how people get beer belly just by frequent drinking. Is it just body fat? Are your organs getting larger or something? Is beer actually making your stomach large and round or are you just gaining weight?

Two main things.

First, men in general add weight in the stomach and midsection, as opposed to anywhere else.

And second, the “mass” we have in other areas tends to be partly muscle. And as many guys get older, they become more sedentary, while at the same time, testosterone drops. So while your sedentary lifestyle causes your gut to grow, that plus testosterone loss is also causing your shoulders, chest, legs to shrink as the muscle fades away.

Those small shoulders and legs make the giant belly look even bigger by comparison.
