13 Flat-Belly Tricks

Eat at this magic hour

"You must eat a snack that contains protein between 3 p.m. and 4 p.m. Go for a protein bar, a piece of low-fat cheese, or some almonds with an organic apple.

No matter what, do not miss that snack. It's important because it boosts metabolism and balances blood sugar. The lower you keep your blood sugar, the lower you keep your insulin, and insulin makes you store fat around your middle. Eating every three to four hours will keep your blood sugar even, but many people tend to go five or six hours between lunch and dinner without eating."

—Natasha Turner, naturopathic doctor, author of The Hormone Diet

Have a ball

"My No. 1 tip: Do the ball exchange three times a week. Lay flat on your back with your arms above your head and legs straight out. Start with a stability ball above your head in your hands. Bring the ball up above your chest as you bring your legs up to meet the ball and place it between your ankles. Bring the ball back down to the floor with your legs and straighten your arms back out over your head.

Repeat the ball exchange 10 to 12 times, remembering to keep your lower back pressed into the floor as you do this move."

Beef up on this belly-zapping hormone

"Eat as close to zero grams of sugar as possible. This will keep insulin levels low and also keep levels of glucagon high. Glucagon, a hormone, is the best friend you could ever have in the struggle for a flat belly! Picture Ms. Pac-Man traveling around your waistline, gobbling up fat to be used as energy. That is glucagon.

The closer to zero grams of sugar you consume, the lower your insulin and the higher your glucagon...it's as simple as that."

—Jorge Cruise, author of The Belly Fat Cure

Chew on this

"Chewing is the No. 1 tip I give to prevent bloating. Chew food until it is like applesauce in your mouth. Digestion begins in the mouth, and without proper chewing, food is not well-digested. Better-digested food means less gas and bloating."

—Dawn Jackson Blatner, RD, author of The Flexitarian Diet

Shake on the sea salt

"The culprit making your tummy bloat? It could be the salt in your diet. Use natural sea salt or kosher salt, which is lower in sodium teaspoon for teaspoon than traditional table salts. And stay away from soy sauce: Even low-sodium soy sauce is still high in sodium and will cause practically instant bloating.

Instead, flavor your food with a little fresh tomato salsa or a hint of cayenne pepper, which has an added benefit of boosting metabolism."

—Susan Irby, "The Bikini Chef" and author of Substitute Yourself Skinny

Punch it out and lose 2 inches fast

"Add boxing to your cardio routine. When you throw punches with weights or at a fast pace, you're working your core in a way that helps to flatten your midsection. You must engage your core to throw punches, and twisting your torso works all the ab muscles.

Boxing also gives you a cardio workout that burns extra calories. Add 16 minutes of boxing three times a week to your regular cardio routine (30 minutes at high intensity four to five times a week), and you can lose up to 2 inches from your waist in four weeks. Simply throw punches while holding 1- or 2-pound weights for 8 minutes, alternating arms, then repeat without weights at a faster pace for 8 more minutes."

Try the flat-belly cheat

"Play up a different body part to draw attention from your middle.

If it's your legs, wear skirts or slim pants. Shoulders—bare them even if just a bit with a boatneck or sweetheart neckline. Cleavage? Make sure your bra does its job. If your bra rides up in the back, the bra has likely stretched out. If it accentuates back flab or if the space between the cups doesn't lie flat, go up a size."

—Kim Johnson Gross, style expert and author of What to Wear for the Rest of Your Life

Size matters

"Eating portion-controlled meals that include whole-grain foods and monounsaturated fats (MUFAs) throughout the day is the best way to eat for a flat belly: People who eat whole grains lose more abdominal fat. And making most of the fats you eat MUFAs reduces ab flab, research says."

—Keri Glassman, RD, author of The O2 Diet and The Snack Factor Diet

Plank often

"The plank is a favorite, but we take it to another level opening and closing the legs like scissors while at the same time raising and dropping the hips! So not only are you strengthening the core but also timing the hips, thighs and waist. [We also do] the trunk twist along with a back row using the bands. The benefit of this exercise will give you flat abs and coke bottle obliques while removing those fat handles from the back and arms."

Skip processed foods

"Refined grains like white bread, crackers, and chips, as well as refined sugars in sweetened drinks and desserts increase inflammation in our bodies. Belly fat is associated with inflammation, so eating too many processed foods will hinder your ability to lose belly fat. Natural foods like fruits, vegetables, and whole grains are full of antioxidants, which have anti-inflammatory properties and may therefore actually prevent belly fat."
