Cutting out alcohol is one of the most effective ways to your gut. Why? Because alcohol is high in calories, containing about 7 per gram, which isn't far from the 9 calories in a gram of fat. But there's another reason to eliminate booze for a month. With beer comes pub grub. It's a fact that when you drink, you want to snack on fatty, salty stuff, from buffalo wings to Goldfish crackers.
