The reason we’re suggesting 45 minutes instead of the typical 30 as one of the ways to lose weight is that a Duke University study found that while 30 minutes of daily walking is enough to prevent weight gain in most relatively sedentary people, exercise beyond 30 minutes results in weight and fat loss. Burning an additional 300 calories a day with three miles of brisk walking (45 minutes should do it) could help you lose 30 pounds in a year without even changing how much you’re eating. Here are 20 hidden reasons your diet isn’t working.
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.
When Tufts University researchers studied the waistlines and diets of 459 people, they found that even in men of similar age and activity level, those who ate white bread frequently weighed more than those who didn’t. “The calories from white bread and refined grains just seem to settle at the waistline more than calories from other foods,” says Katherine Tucker, Ph.D., the study author.
Sometimes, to whip your body into shape, you have to get a little nutty. While nuts are high in fat, it’s that very fat that makes them such powerful weapons in the war against a ballooning belly. In fact, research from Reina Sofia University Hospital reveals that study participants who consumed a diet rich in monounsaturated fats, like those in nuts, over a 28-day period gained less belly fat than their saturated fat-consuming counterparts while improving their insulin sensitivity.
You already know that a perfect diet doesn't exist, but many of us still can't resist the urge to kick ourselves when we indulge, eat too much, or get thrown off course from restrictive diets. The problem: This only makes it more difficult, stressful, and downright impossible to lose weight. So rather than beating yourself up for eating foods you think you shouldn't, let it go. Treating yourself to about 200 calories worth of deliciousness each day — something that feels indulgent to you — can help you stay on track for the long-haul, so allow yourself to eat, breathe, and indulge. Food should be joyful, not agonizing!
One easy way to find out if you’re carrying too much abdominal fat is to wrap a measuring tape around your body at the top of your hipbones. If your number is more than 35 inches, it may be time to take action. The good news: Getting rid of belly fat is simpler than you might think. With the right plan, it’s actually easier to lose than stubborn lower-body fat or the seemingly impossible to tone back-of-the-arm flab. Stick to these diet and exercise guidelines, and you’ll be slimmer — and healthier — by summer.
Still try to consume as many veggies and fruits as possible. Even if you don't enjoy carrots or salads, do what it takes to get yourself to eat them (e.g. plug your nose and chase bites of veggies with water like you did when you took medicine as a kid). You really have to try everything. Also, stick with the lean meats like fish or poultry. If you don't eat a healthy diet, you'll have to exercise more.
Women’s challenge with weight loss also comes down to nature. Nature wants to preserve a woman’s ability to bear children. When you’re in a calorie deficit, it can interfere with your fertility, so your body fights weight loss to prevent jeopardizing your reproductive capacity. So don’t cut more than 1,000 calories a day or eat fewer than 1,200 calories daily.
There’s one thing to like about visceral fat: It yields fairly easily to aerobic exercise. Vaporizing calories via running, biking, swimming—anything that gets your heart rate up—is an effective way to whittle your middle. In fact, one 2011 study from Duke University Medical Center, published in the American Journal of Physiology, found the sweet spot: Jogging the equivalent of 12 miles a week was even more effective in reducing visceral fat than resistance training three times per week. However, both types of exercise were beneficial when it came to belly fat, the researchers say. (Don’t have time to hit the gym? Try these fun at-home cardio workouts if you’re in a pinch.)
"Inadequate intake of calories, especially protein, causes the body to breakdown muscle tissue to meet the needs for amino acids," says Cederquist. "I have my patients focus on obtaining adequate lean protein and spreading it throughout the day." Her recommendation: focus on 100 grams per day, which breaks down into three to four ounces of protein at breakfast, lunch, and dinner, and a few ounces for snacks.
