This just in: Saturated fat packs on more visceral fat than polyunsaturated ones, according to a recent Swedish study. When subjects ate 750 more calories daily for seven weeks—either in the form of palm oil (saturated) or sunflower oil (polyunsaturated)—the former gained more visceral fat while the latter gained more muscle mass and less body fat. Polyunsaturated fats can be found in nuts, seeds, and fish.
As women age, weight creeps up too, with the average women gaining about one pound per year in their 40s and 50s, resulting in an added 10 to 15 pounds. The drop in estrogen levels during this time of perimenopause (the years leading up to menopause) contributes to weight gain and can change the way you distribute fat. You may gain weight in your belly more readily than you did in younger years.
A little garlic in your meals could mean a lot less weight around your middle. The results of a Korean study found that mice given a high-fat diet supplemented with garlic lost significantly more weight and abdominal fat than those who just ate fatty foods. Even better, they also improved their liver health, making it easier to stay healthy and burn off that excess fat in the long term.

When your body is low on calcium, it produces a hormone that signals the body to store visceral fat. Meeting your recommended daily calcium needs (that’s 1,000 milligrams for adults) can help reduce levels of this hormone. And a recent study published in Obesity Research found that calcium from dairy has a stronger effect than calcium from other sources. I recommend eating low-fat Greek yogurt as a daily snack (just six ounces contain about 20 percent of your recommended dietary allowance for calcium), though any low-fat dairy will do.
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.
