Target your deepest ab muscles with The Boat: Lie face up on a mat with arms by your sides. Lift your upper body off the ground by rolling through the spine and reaching arms forward. At the same time, raise your legs so that you're balancing on your butt, knees bent and shins parallel to the ground. Slowly roll back down onto the mat, lowering legs and arms. That’s 1 rep. Do 5 reps per set, resting 30 to 60 seconds between sets.
There are healthy belly bacteria, and then there are bad belly bacteria, the later of which studies indicate overweight people have more of in their gut. To keep the fat-causing bugs at bay, you need to eat a variety of foods that support their healthy counterparts—the kind found in the bellies of slim people. Examples of probiotic-rich foods that help you lose weight by aiding digestion include kefir, kombucha, and yogurt.
Choose whole fruits over juices, fresh over canned, water over soft drinks. Avoid bakery staples like cakes and cookies. Canned and packaged foods contain a lot of sodium and very less fiber and nutrients. Excess sodium retains more water, puffing up your belly. Stay away from sugar substitutes as well; they are only partially digested by your body.
But regardless of how tight your ab muscles are, they can't erase belly fat that lies above (subcutaneous) or below them (visceral fat). Those you'll have to burn off—and according to Olson's research, the best belly fat-melting method is Tabata intervals. Maximum-effort cardio intervals raise your level of adrenaline, the fight-or-flight hormone that's the secret sauce to burning fat.
"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.”
When doing an abs circuit, think about all three planes of motion, says celebrity trainer Gunnar Peterson, who works with Sofia Vergara, Kim Kardashian, and Vanessa Lachey: Try crunches and reverse crunches to hit your sagittal (front to back and up and down) plane, standing side bends for frontal (side-to-side) movement, and chops or twists for transverse (rotational) action. This will help challenge and therefore define your abs.

A study by Eat This, Not That! magazine advisor Brian Wansink, director of the Cornell Food and Brand Lab, found that you can estimate how much someone weighs by taking a photo of their kitchen counter. After analyzing photos of 200 kitchens, he found that women who have soda sitting on their countertops weigh an average 26 pounds more while those who have cookies weigh about eight pounds more. The biggest surprise: Keeping cereal on your counter leads to an additional 20 pounds of body weight. The lesson here is to clean empty calories off your countertops to start losing weight.

Make dessert an occasional treat rather than an everyday event so it doesn’t become a habit, says Rumsey. If you’re already feeling bloated, eating sweets full of simple carbs could just make it worse, says Armul. “But if it’s been a healthy day and you’ve stayed active, a small portion of dessert should be fine and won’t cause major bloating,” she says. The key to making it fit into your flat-belly day is sticking with one small portion—a serving of ice cream is probably smaller than your usual scoop (or two)—or picking a healthier choice, like frozen fruit, to satisfy your sweet tooth.


I have a question on doing the Double Leg Lifts. I’m about to start Day 7. Ever since day one whenever I try to do the DLLs, moving my legs down, I get this arch in my back. When I get this arch unless I’m holding onto something as a kind of counterweight I can’t lift my legs back up.

Even calorie-free sodas can make your belly bigger because the carbonation will bloat you up. “With carbonated beverages, there’s nowhere else for gas to go but out, so either belch or gas,” says Crandall. Plus, the artificial sweeteners in diet drinks can cause bloating and gas in some people, says Armul. Try water infused with lemon or cucumbers instead for a flavorful, refreshing drink. Here’s how stomach doctors deal with belly bloat.
When people hear the term hormonal imbalance, most immediately think about the change of life, menopause. Although it's true that women going through menopause have significant hormonal changes, the issues associated with hormonal imbalance, such as abdominal weight gain, typically begin in a woman's early to mid-thirties and a man's early forties.

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."

• Too much estrogen circulating in the body increases body fat, and fatty tissue within the body produces and stores more estrogen. Body fat contains an enzyme that converts adrenal steroids to estrogen. At a cellular level, body fat continues to produce more estrogen, and a high estrogen level, in turn, causes the body to increase its store of fatty tissue. In other words, your belly becomes a 'fat magnet.'
"Researchers are now discovering that gut bacteria also seem to play a role in the complex process of weight loss and weight gain," he writes. "We don't know exactly how much impact our Little Buddies have on our weight, but we're learning enough to believe that understanding the connection more fully may help us as we confront the obesity epidemic in the United States — and in our own bodies."
