Instead, build up to at least 150 minutes per week of moderate-intensity cardio, such as swimming, jogging or hiking. A duration of 250 minutes per week will lead to more significant weight loss, explains the American College of Sports Medicine. This means 250 minutes a week for several weeks or months, though; you're unlikely to see dramatic results after one week.
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.
Lipman suggests sipping it as soon as you wake up and after each meal. "Bitter foods like lemon help stimulate your body's GI juices and aid the start of the digestion process. When digestion is robust, your body breaks down food better and absorbs more of its nutrients, both of which help you maintain a healthy weight and flat belly." Arugula, dandelion root, and apple cider vinegar will also do the trick, so munch on a salad with these greens before your main course — bonus if it's dressed with cider vinaigrette.
Limit foods high in refined carbohydrates and refined sugar (white bread, white pasta, white rice), and replace them with high fibre ‘complex carbs’ – think: whole grains, brown rice, sweet potato, oats, beans and pulses. Fill your boots with as many vegetables as possible – they’re low calorie, high in micronutrients, and the fibre in them will keep you full.
This is what's known as insulin resistance. Basically, when your body doesn't respond well to insulin, it actually makes more of the stuff, according to the National Institute of Diabetes and Digestive and Kidney Diseases. And that can lead to fat storage, especially around the middle of your body. That's where protein comes into play: A diet high in protein may protect you against insulin resistance, says Aronne.
The most important thing you need to do is to program yourself mentally. Don't use a scale to measure your progress. If you work out with weights, you may gain a few pounds while losing inches around the waist. Instead, use that pair of jeans that you want to fit into again, or a pair that fits you now. You'll see a slight change every few weeks, and that should give you confidence.
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.
In a 2012 study in the journal Obesity, subjects who increased their soluble fiber intake by 10 grams a day—the equivalent of two small apples, one cup of green peas, and one half-cup of pinto beans—reduced visceral fat by 3.7 percent after five years. Even more, participants who also engaged in moderate physical activity (exercising vigorously two to four times a week) experienced a 7.4 decrease in visceral fat over the same period of time.
