Want a flatter stomach? Look in your glass—milk and soda are two major causes of tummy inflation. Approximately 65 percent of the human population has a reduced ability to digest lactose after infancy, which means that your glass of warm milk before bed may be the reason you wake up with too-tight pajamas. These are signs you might be lactose intolerant. And when it comes to soda, both regular and diet are belly busters both from the sweeteners used and the carbonation. Try eliminating these from your diet and see if it helps flatten your tummy.
But you need to exercise, too. In Slentz's study, walking or jogging miles a week kept visceral and subcutaneous fat at bay, and jogging miles melted them off. At 11 miles a week, it made no difference whether people in the study walked or jogged, and it's fairly safe to say that it wouldn't at miles either. "It's not the intensity of the exercise that matters," Slentz says. "It's the amount."
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.
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.
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."
What causes it? Your genes, for one thing. "Some families just carry most of their weight in their bellies, no matter how thin they are," says Caroline Cederquist, M.D., author of The MD Factor Diet. But visceral fat gets worse for all of us as we get older, especially if we're under a lot of stress or not sleeping well, says nutritionist Sara Vance, author of The Perfect Metabolism Plan. That's thanks to hormones that make us hungrier even as our bodies are practically hoarding fat.
"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."
