Women who wake up and go to bed at the same time each day have lower levels of body fat, according to a study of more than 300 women from Brigham Young University in Utah. Chaotic sleep habits cause your internal clock to go haywire, which in turn causes your body to secrete fat-storing hormones like cortisol. The sweet spot? Try not to stray an hour from your usual sleep pattern, the study authors say. More than a 90-minute difference in sleep and wake times were linked to more body fat. (Tossing and turning?

In that age range, girls are just hitting puberty. It is a period of faster growth than any other time in their lives since infancy. Limiting calories is therefore not a good idea for girls in that age group, since their bodies need extra energy in order to grow, unless they are having health problems due to weight. Making healthy dietary choices and getting plenty of exercise are good ideas. Just keep in mind - the belly fat that many girls accumulate early in puberty tends to move elsewhere in their later teens.
Avoid over stuffing yourself at meals; eat small meals throughout the day. Chewing gum and drinking with a straw can cause excess air to gather in the digestive tract. Carbonated beverages, spicy foods, large servings of beans or cruciferous vegetables, dried fruits and fruit juice often induce gas and bloating. If you're lactose intolerant, avoid dairy products to help reduce belly swelling; make sure you obtain important nutrients, such as calcium and vitamin D, from milk alternatives or other fortified foods.
The study authors believe that sleep deprivation can cause your body to produce extra hunger hormones (like ghrelin) and fewer satiety hormones (like leptin). This means you’ll feel hungrier and have a harder time controlling your cravings once they hit. Most adults should aim for at least 7 to 9 hours of shuteye per night, per the National Sleep Foundation’s recommendations.
Stubborn belly fat is something most of us deal with, and a fast solution to getting rid of it would be ideal. Unfortunately, there's no safe, quick fix to losing weight just in our bellies. That's because our bodies aren't able to simply spot reduce, which means doing a ton of crunches every day won't necessarily yield the results you're looking for in your midsection.
Luckily, exercise can help spur things along when it comes to that pesky stomach fat. “Visceral fat responds well when… [you] start exercising and watching your calories and what you eat,” Harris-Pincus says. And while endless crunches aren’t your ticket to a flat stomach, it is still important to train your ab muscles. “Everything radiates from the center of your body – your balance, your posture, your functional movement,” says Joe Ardito, founder of Fit Crush NYC. “You can perform better when you have a strong core.”
Belly fat may be dangerous, but it's also responsive to traditional weight-loss strategies of diet and exercise. One pound of fat equals 3,500 calories; thus, to lose a pound, you must consume 3,500 calories fewer than you burn. In a week, you can't afford much more than a 3,500- or 7,000-calorie deficit without severely depriving yourself of nutrients and solid food. This deficit means you'll lose 1 or 2 pounds per week.
The good news is that studies show that moderate- to high-intensity aerobic exercise such as running can help reduce visceral fat, even without changing your diet. Combining aerobic exercise with a healthy, low-calorie diet is even better for both overall weight loss and visceral fat loss, though exercise seems to be more effective than diet when it comes to targeting visceral fat.
Science backs these ideas up when it comes shedding belly fat: In one study published in The Journal of Nutrition, researchers had overweight men and women follow a high-protein diet (30 percent protein, 40 percent carbs, and 30 percent fat) or a high-carb diet (15 percent protein, 55 percent carbs, and 30 percent fat). After one year of weight loss and maintenance, they found that the high-protein group experienced a 21 percent greater weight loss and 27 percent greater body fat loss on average than the high-carb group.
Walking puts all of the abdominal muscles to work. Make sure you swing your arms and contract your midsection while you walk, and maintain a brisk pace. Once you get your body accustomed to a daily walk, you'll hate to go a day without it. Walk for at least thirty minutes each time to achieve the aerobic effect, and be sure to drink plenty of water.
Instead of subjecting yourself to another endless workout, crank up the intensity and you’ll see results faster than you ever thought possible. The results of a study conducted at McMaster University in Ontario reveal that adult male study subjects who exercised intensely for a single minute had equivalent respiratory and metabolic changes to those who worked out at a slower pace for close to an hour, so if you want to burn through that belly fat, say so long to slow and steady.
Losing belly fat shouldn’t mean strict dieting or deprivation. “People often think that you have to eat certain foods or avoid certain foods [to lose weight] and in reality, it comes down to eating more of a balanced diet that is portion- and calorie-controlled,” says Zeratsky. “This allows your body to have enough energy to do what it wants to do while managing weight.”
