A diet that’s low in fat and carbohydrates can improve artery function, according to a 2012 study by Johns Hopkins researchers. After six months, those on the low-carb diet had lost more weight, and at a faster pace. But in both groups, when weight was lost—and especially when belly fat shrank—the arteries were able to expand better, allowing blood to travel more freely. The study shows that you don’t have to cut out all dietary fat to shrink belly fat. For heart health, simply losing weight and exercising seems to be key.
Not much of a coffee drinker? Tea is also a natural diuretic, and types of herbal tea such as dandelion or fennel root can also lend a hand. In fact: When a recent study compared the metabolic effect of green tea (in extract) with that of a placebo, researchers found that the green-tea drinkers burned about 70 additional calories in a 24-hour period.
5. Stand up. Researchers at the Mayo Clinic found that lean people spend two more hours per day on their feet than overweight people. Participants in the study who stood, paced, and fidgeted burned as many as 350 extra calories a day and were much leaner than those who didn’t move as much. Get up from your desk at work, talk on the phone while standing, and stay on your feet in waiting rooms—the simplest effort will yield an extra calorie burn that may help you shed those remaining pounds.
