We residents of Beer City, USA know that IPAs are more popular ever. And let's be honest, there are a lot of great things about them: they have more complex tastes, higher alcohol content, and you just look cooler drinking them.

But here's a pretty big downside: they're giving you man boobs.

IPAs usually use more hops than other beers (we know this). But what you probably didn't know is that herbalists use hops to help women increase their estrogen production.

What does that mean? Well, it means that when a man starts drinking IPAs instead of less hoppy beers, his estrogen levels can increase, and that can lead to man boobs.

Craft beers also generally have more calories than beers like Coors Light or Bud Light. So you could end up gaining more weight when drinking them, which could also contribute to your man boobs.
