IBS, or irritable bowel syndrome, is the most common gastrointestinal disorder. IBS symptoms include nausea, diarrhea, constipation, stomach pain, and bloating—So. Much. Bloating. While the causes aren't all known, it's thought to be linked to lifestyle factors like diet, exercise, hormones, and stress. These natural remedies for IBS can help. Sufferers often find that making changes in these areas eliminates or reduces their IBS (and their stomach circumference!).
Cruciferous veggies are one of the healthiest vegetables you can eat, but unfortunately they're also the ones most likely to cause your tummy to inflate. Thanks to raffinose, a compound that produces extra gas as it breaks down, broccoli, cabbage, cauliflower and the like can seriously increase your waistline. But don't ditch them forever. Just save them for meals where you can wear loose pants. Here are other surprising foods that cause gas.
Protein is kryptonite to belly fat. When you eat protein, your body has to expend a lot of calories in digestion—about 25 calories for every 100 calories you eat (compared with only 10 to 15 calories for fats and carbs). With that said, stock your kitchen with boneless skinless chicken breast, lean ground turkey, lean beef, lamb, wild salmon, shrimp, scallops, cod, tuna, and halibut. Looking for a new tasty way to eat salmon? Check out this Zero Belly Green Tea Poached Salmon Recipe for some inspiration.
Shift your weight into your right foot. Hug your left shin into your chest, then extend it straight back behind you so it’s parallel to the ground. Flex your left foot and point the toes down. Bring your fingertips to the ground to stabilize yourself if you need to. Reach your arms out in front of you so your body is in a straight line from your fingertips all the way down your back and out through your left heel. Stay here for 3 long, deep breaths then slowly return to standing. Repeat on the other side.
Look for a brand of Greek yogurt that contains live and active cultures, which will promote healthy bacteria in your gut to prevent bloating. (These are signs you could have an unhealthy gut.) Plus, the protein in the yogurt will keep you full. Beef it up with fiber-rich oats, berries, and chia seeds for an extra filling morning meal—just don’t go overboard if your body isn’t used to digesting that much fiber, says Jessica Crandall, RDN, CDE, spokesperson for the Academy of Nutrition and Dietetics. “If you’re not used to that amount of fiber it causes gas, but if you work up to it slowly, it promotes a healthy GI system,” she says. Slowly add a little more fiber to your diet every day for a flatter belly, and increase your fluid intake to aid digestion and reduce icky symptoms like diarrhea and bloating—here’s how to get more fiber into your diet without really trying.

• 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.'
Hara hachi bu is a Japanese practice to “Eat until 80% full.” If you follow Hara hachi bu, you could save nearly 300 calories per day. It can take up to 30 minutes for the body to register satiety signals, according to research, so consider using chopsticks to slow your pace and feel your fullness. According to a study in the American Journal of Preventive Medicine, healthy-weight customers were nearly three times more likely to use chopsticks than obese customers.

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.
