With a growing number of overweight people, you're likely to see at least one pot belly on your morning commute.

A pot belly, or beer belly, is excessive fat in the center of the abdomen which makes the belly round and protruding. While women can get a pot belly, they tend to be more prevalent in men. The biggest causes are overeating and a sedentary lifestyle.

The only way to lose a pot belly is to lose weight. You cannot spot train body parts, but crunches may help tone the stomach muscles. Additionally, you must burn more calories than you consume each day, which is easier if you follow a low-fat, reduced-calorie diet and include at least 30 to 60 minutes of vigorous exercise in your daily routine.

Even if you don't have an excessive amount of fat hanging over your jeans, but still want to slim your stomach, avoiding foods that contribute to bloating can help. Cut back on salt and eliminate gassy foods like broccoli, onions and cauliflower. Carbonated drinks (like soda), alcohol, fried foods and spicy meals can also lead to bloating.
