10 Reasons Your Belly Fat Isn't Going Away

How to trim your tummy.

— -- intro:

To shed belly fat, it's good to eat fat—specifically monounsaturated fatty acids (MUFAs). When researchers in one study asked women to switch to a 1,600-calorie, high-MUFA diet, they lost a third of their belly fat in a month. "MUFAs are satiating, so they help you eat fewer poor-quality foods," says David Katz, MD, director of the Yale Prevention Research Center.

Belly blaster: Have a serving of MUFAs—like a handful of nuts, a tablespoon of olive oil, or a quarter of an avocado—with every meal and snack.

Simple carbs (like chips) and added sugar (in items like sweetened drinks) cause your blood sugar to spike, which triggers a flood of insulin—a hormone that encourages your liver to store fat in your middle.

Belly blaster: Instead of focusing on cutting out junk, center your efforts on adding in healthy fare (think extra servings of vegetables at each meal). As Dr. Katz says, "Filling your tank with high-quality fuel thwarts hunger."

Belly blaster: Dine on fatty fish like salmon or trout once a week to get a good dose of PUFAs. The rest of the time, reduce your intake of red meat and opt instead for protein low in saturated fat, such as legumes and chicken.

Research has shown that high-intensity interval training, or HIIT—bursts of vigorous activity followed by short periods of gentle activity or rest—boasts belly-shrinking benefits. "High-intensity exercise seems to be more effective at reducing insulin, triglycerides, and cortisol, and it burns more calories in less time, too," notes Shawn Talbot, PhD, a fellow of the American College of Sports Medicine.

Belly blaster: If you enjoy biking or running, for example, accelerate to a pace that makes it hard to talk for two minutes; then slow down for a minute, and repeat until you're done. Like resistance training? Try a series of moves like squats or push-ups for two minutes each with a 60-second break between them.
