Removing saturated fat (the kind found most often in animal products like meat) and replacing it with monounsaturated fat in moderation is undoubtedly a good thing. It helps lower LDL “bad” cholesterol and the chance of heart attack and stroke. So it’s a good approach for anyone with diabetes, high blood pressure, high cholesterol, or heart disease.
Just don't wait until you blow the tape-measure test to start defending your belly from this flab. Step one is to toss the trans fats, which are found in prepackaged treats under the alias partially hydrogenated oils and have been shown to pack on body fat, particularly in the abdomen. Replace them with monounsaturated fats — for example, olive oil and those in walnuts and avocados — which help your body metabolize belly fat. And swig some reduced-fat milk, like 1 percent or skim, while you're at it: Calcium increases the activity of enzymes that break down fat cells and reduces the stress hormone cortisol, which triggers your body to hoard belly fat.
