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.
We all have an Achilles heel: the one food or meal that we can't seem to help digging into. But Mark Mincolla, Ph.D., nutrition expert and author of The Whole Health Diet, recommends taking the time to visualize that food multiple times throughout the day, as research shows doing so makes you actually want it less. When that theory was put to the test, scientists found that those who repeatedly imagined their guilty-pleasure foods reduced their calorie consumption of that food by as much as 50 percent. And it wasn't because they found it to be less desirable — if you love pizza, you love pizza — but rather because they just didn't feel like eating it when given the option because they had already thought about it so much. Reverse psychology, much?

The traditional hot-dog topping can do serious wonders for your waistline. "Fermented foods like sauerkraut, pickled veggies, and kimchi are some of the best sources of probiotics — a form of good bacteria that support healthy digestion and decrease bloat," says Frank Lipman, M.D., founder of Eleven Eleven Wellness Center in New York City. "That's important, since diets low in probiotics can cause bad bacteria to overtake the good ones, leading to health problems ranging from autoimmune diseases to weight gain."

Craving something sweet? This fruit — along with colorful radishes, tomatoes, and carrots — contains arabinogalactans, a plant-based fiber and prebiotic that feeds the friendly bacteria that help your metabolism function optimally. The fiber also kills E. coli and klebsiella — two types of bad bacteria associated with carrying excess weight, Kellman says. Chop kiwi into grilled chicken salads or purée into smoothies for a colorful and sweet kick.

Add a cup of low-fat milk, a part-skim mozzarella stick, or a half cup of low-sodium cottage cheese to breakfast, and you may have a belly-busting win. While lots of research links calcium with lower body weights, results from a 2014 study suggest that calcium-containing foods may reduce waist circumference in those genetically predisposed to carrying weight in their midsection.

You know you're supposed to eat more protein to lose weight, but you might not know exactly why. Well, it actually has to do with how your body handles insulin. "Your body starts to produce more insulin as you age, since your muscle and fat cells aren't responding to it properly," explains Louis Aronne, M.D., director of the obesity clinic at Cornell University.
