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.
Stress skyrockets your levels of cortisol, often called "the belly fat" hormone because it signals to the body to store fat around your waist. Add the daily stressors of living our modern lifestyle and you can see how cortisol can be constantly coursing through your veins. This perma-stress mode isn't good for a lot of healthy reasons, your tummy being just one of them, so it's important to take time every day to de-stress. Yoga, meditation, walking, journaling, doing a hands-on hobby, or playing a musical instrument are all great time-tested methods. (Hint: Know what isn't? Watching television. The boob tube actually increases your levels of cortisol!)
If you can do more than five reps of an exercise, pick up a heavier weight. As you build muscles and your body gets stronger, you can increase your load to challenge your body. It’s particularly important to work larger muscle groups, like your glutes, with a heavier weight. “This will burn fat, in the belly and other areas, quicker than any ab exercise.”
“Soda, both diet and regular, have absolutely no nutritional benefits and may even have serious health implications,” says Gina Consalvo, MA, RD, LDN, a Pennsylvania-based registered dietitian. “Not only are they loaded with empty calories, harmful preservatives, sugar or artificial sweeteners, they also have dangerous artificial coloring derived from coal sources,” explains Consalvo. But that’s not even the worst part. “To prevent mold growth in the cans and bottles, makers add the preservative potassium benzoate (a known carcinogen linked to thyroid damage, leukemia and other cancers) into the cans.” Consalvo suggests eliminating soda and drinking water, seltzer or detox tea instead.
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.

Reading the nutrition label of packaged foods is important, but you also want to carefully review the ingredients list. While the nutrition label will tell you how many calories and grams of fat and sugar are in the food, the ingredients list will tell you what’s exactly in it. Ask yourself: Does it have processed oils? What is the source of the sugar content? Are there food additives?
