Getting rid of your belly bulge is important for more than just vanity's sake. Excess abdominal fat—particularly visceral fat, the kind that surrounds your organs and puffs your stomach into a "beer gut"—is a predictor of heart disease, type 2 diabetes, insulin resistance, and some cancers. If diet and exercise haven't done much to reduce your pooch, then your hormones, your age, and other genetic factors may be the reason why. Read on for 11 possible reasons why your belly fat won't budge.
Belly fat may be dangerous, but it's also responsive to traditional weight-loss strategies of diet and exercise. One pound of fat equals 3,500 calories; thus, to lose a pound, you must consume 3,500 calories fewer than you burn. In a week, you can't afford much more than a 3,500- or 7,000-calorie deficit without severely depriving yourself of nutrients and solid food. This deficit means you'll lose 1 or 2 pounds per week.
