"Nuts are surprisingly an excellent food to support weight loss. Although they're rich in calories, they've been associated with weight loss and weight loss maintenance," says Hever. "Researchers suggest this is due the fact that nuts promote satiety, thereby leading to compensation of calories elsewhere in the diet. Also, nuts have been shown to increase resting metabolism." A faster metabolism can help flush out any bloating, so this is definitely a plus for slipping into your skinny jeans or favorite cocktail dress.
"Refined grains like white bread, crackers, and chips, as well as refined sugars in sweetened drinks and desserts increase inflammation in our bodies," says Patton. "Belly fat is associated with inflammation, so eating too many processed foods will hinder your ability to lose belly fat." Natural foods like fruits, vegetables, and whole grains are full of antioxidants, which have anti-inflammatory properties and may therefore actually prevent belly fat, Patton says.
Everybody loves their quinoa, but it's time to elevate this less-popular grain to superfood status. "While processed grains and sugar are the main culprits for promoting abdominal fat, whole grains are in another category altogether," says St.John. "Intact grains [i.e., ones that haven't been stripped of their nutrients, as is frequently the case with 'white' options] contain fiber which slows digestion and absorption of the grains, which in turn reduces the amount of insulin released by the body." What does this mean for you? The less insulin your body releases equals less abdominal fat tacking itself onto your tummy.
Belly fat also responds to a lower-calorie diet that's full of healthy, unprocessed foods. Go for lean protein, fresh produce and whole grains at meals. When you have just a week to lose as much as possible, ban all sweetened drinks -- including soda and juice -- bakery treats and ice cream. Also avoid refined grains, such as pizza and white bread, as well as alcohol. Keep your portion sizes to just 2 to 4 ounces for meats and other proteins and about 1/2 cup for grains. Over the long term, these dietary revisions help you drop belly fat.
To get the most of this natural source of probiotics, seek out yogurts like those by Fage, Dannon, and Oikos, which contain lactobacillus. In a 24-week study published in the British Journal of Nutrition, women who consumed this type of probiotic lost twice as much weight as those who didn't regularly include it in their diets. Besides eating yogurt at breakfast, try using plain or Greek yogurt in chicken or salads in lieu of mayo or sour cream.
Those trans fats on your menu are hiding out in plain sight and sabotaging your lean belly plans every time you eat them. If a food product says it contains partially hydrogenated oils, you’re eating trans fat, which can increase your risk of heart disease, high cholesterol, and obesity with every bite. In fact, research conducted at Wake Forest University reveals that monkeys whose diets contained eight percent trans fat upped their body fat by 7.2 percent over a six-year study, while those who ate monounsaturated fat gained just a fraction of that amount. Instead of letting harmful trans fat take up space on your menu, fill up with the 20 Healthy Fats to Make You Thin.
If you have a big-time sweet tooth, grabbing a grapefruit could help cut back on calories from late-night treats. "The interesting thing about grapefruit, and citrus fruits in general, is that they provide an intense, satisfying flavor that rarely gets chanced by sweets," Taub-Dix says. "A grapefruit or citrus fruit after dinner could keep you from reaching for a sweet dessert." Yeah, that's right: a 52-calorie grapefruit can satisfy just as much as a 400-calorie piece of chocolate cake. Sorry, brain, but you just got played.
But you’ll likely experience some benefit before then. Fiber helps slow down your digestion and requires more chewing, which helps signal to your body that it’s full, keeping your hunger in check throughout the day. One small study published in Food & Nutrition Research actually found that men who ate meals rich in high-fiber foods, like beans and peas, felt more satisfied than those who focused only on protein-rich foods, like pork and veal. Adult women should aim to eat 25 to 28 grams of fiber per day.
“Include lots of nutrient-rich vegetables, a source of protein and some healthy, unprocessed carbs,” says Belalij. “Start with leafy greens such as spinach, kale and collard greens, then add carrots, broccoli and peas. Lean meats, including turkey and chicken, are ideal as they are lower in fat and therefore calories, or, if you are vegetarian/vegan, add in tofu or a handful of nuts such as pine, cashew or almonds and a sprinkling of seeds (sunflower, sesame, pumpkin). When it comes to carbohydrates, rice, quinoa and potatoes are perfect.”
