Why does it only happen to my stomach? Why doesn't it affect other body parts?
Belly fat is visceral fat, and it is heavily influenced by the hormone estrogen. Yeah, guys, that's right: estrogen. Drinking a lot of beer will jack up your estrogen levels giving you "bitch tits" and a fat beer gut. As for the females, you have enough estrogen in your body, no need to give it any more.
How can I prevent it?
The obvious way would be to cut back on your crazy drinking. But, if you’re going out for a round of beers with friends, have a healthy meal beforehand. The toxic impact of alcohol is increased if there's no food in your belly. Plus, it will fight off the late-night temptations for junk food. If you are a legit boozehound, and there’s no stopping you, then switch to vodka or tequila.
How can I get rid of it once it’s happened?
Getting rid of a beer belly is as simple as changing up your diet to meat and vegetables, cutting all preservatives, and incorporating high-intensity exercise to your life.
