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.
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?

High-volume, low-calorie greens will fill you up, without filling you out. Test panelist Kyle Cambridge says regular salads turbocharged his success: “My wife Stacie and I decided to add salad to each meal, and the pounds started melting off.” Kyle lost 25 pounds and four inches in just six weeks on the program. “I even had to buy a new belt!” he said. “But the best was when Stacie came up to me in the kitchen, and gave me a hug. She laughed and smiled and said ‘I can wrap my hands around you again.'”
About 65 percent of the human body is made up of water, so it's important to replenish the water you lose each day. According to a study conducted among 10,000 adults aged 18 to 64 over a three year period, drinking plenty of water and eating water-filled fruits and vegetables significantly improves your ability to lose weight fast, especially if you are overweight or obese.
It’s impossible to target belly fat specifically when you diet. But losing weight overall will help shrink your waistline; more importantly, it will help reduce the dangerous layer of visceral fat, a type of fat within the abdominal cavity that you can’t see but that heightens health risks, says Kerry Stewart, Ed.D., director of Clinical and Research Physiology at Johns Hopkins.
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.
Make sure that everything you're eating is whole — as in nothing processed or packaged. Since salt is a preservative, these are the foods that are highest in sodium — something to keep in mind when planning your meals. Plan on making sure that all items you choose are fresh. That means filling up on fresh fruits and veggies, whole grains, low-fat dairy, and lean protein.
"Your body needs a healthy balance of exercise and rest. Doing too much prevents the body from shifting excess fat. Exercising without rest can impact our levels of the steroid hormone cortisol and cause an increase of stubborn fat stored in the belly. Not allowing your body to recover can increase the risk of injury too, so make sure you factor in rest days to your plan."
Have you been consistent with workouts but haven’t gotten the results you were hoping for? Your low-key resolution is to change up your workout. Commit to the same number of workouts per week, but make these workouts completely different. If you’ve been going to yoga three times a week, go to a cycling class instead. Or if you’re walking on the treadmill every day, move over to the recumbent bike instead. By sparking a change in your routine, your muscles will be forced to work differently and hopefully you’ll begin to see the results you’ve been hoping for!
