A 2012 study in the Journal of Functional Foods found that people who drank one and a half cups of green tea enriched with a total of 609 milligrams of catechins (a group of antioxidants that have been shown to help burn fat cells) every day for 12 weeks lost almost 16 times as much visceral fat as those who consumed green tea without the added antioxidants. To achieve similar results with store-bought green tea, you’ll need to brew two to four cups daily (many varieties can contain 160 to 470 milligrams of catechins per cup).

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.
Hate having to pass on the potatoes for the sake of your pants size? Well, you may not have to. Just eat them cold—as in vinegar potato salad. If you chill potatoes overnight, they form something called resistant starch crystals—a constituent of fiber that triggers the production of two hunger-halting hormones, according to research. And resistant starch helps the body incinerate more fat for fuel while making less fat available to stash away in fat cells. (Related: Find out how vinegar potato salads help your blood sugar, too.)
Try this interval-training trick on the elliptical trainer: Ride for 30 seconds as fast as you can, then immediately reverse your direction and ride for 30 additional seconds just as fast in the opposite direction. Rest 60 seconds, and repeat. The force of stopping your momentum, as well as going from a dead stop to full speed twice in the same interval, will give your fat-burning efforts a massive boost, says Alwyn Cosgrove, C.S.C.S.
Your physician may use magnetic resonance imaging (MRI) to record detailed pictures of your fat tissue. They may also use CAT or CT scans to produce cross-sectional images of your body or other bioelectrical impedance machines to differentiate between fat tissues. Calipers are sometimes used to measure fat under muscle but are not considered to be an accurate tool.
