"This is where it's called visceral fat, which is in and around our organs -- whereas the fat present all over our body under our skin is subcutaneous fat. When there's high amounts of visceral fat, it increases the risk of developing those diseases like metabolic syndrome and heart disease. Being aware of, and managing, this is incredibly important."
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.
By now you know to swap out regular yogurt for the Greek stuff and white bread for whole-wheat. But if you don't look closely, a product labeled "Greek" or "whole-wheat" may not be what it seems. A typical one-cup serving of plain Greek yogurt (like Fage 0%) provides 23 grams of protein and 9 grams of sugar, making it a smart choice. But another version of what looks like the same product can have over 18 grams of sugar. Not good, as the American Heart Association suggests women only eat 30 grams in an entire day. The same trickery goes for whole-wheat bread packages — some companies are loading it with high-fructose corn syrup, an unnatural additive that's 20 times sweeter than sugar and not recognized by the brain. Studies show that eating the stuff confuses your body's hormones so you don't realize when you're full, essentially forcing you to overeat when you thought you were making a healthy choice.
