These weight-loss tea leaves are partially oxidized (black teas, for instance, are fully oxidized), lending a smooth, but bold taste to the brew. Happily, they also help boost your body’s ability to metabolize fats, reports a 2009 study from Chinese researchers. When obese and overweight participants consumed oolong for six weeks about two-thirds lost more than 2.2 pounds and 12 percent belly fat. Bonus: They ended the study with healthier cholesterol and triglyceride scores, all adding up to a stronger ticker. (Here are 23 tricks to flatten your belly without exercise.)
Instead, explains Dr. Rhonda Low, a Vancouver family physician, "because the regimens are usually very restrictive and very low in calories, weight loss occurs because of initial water loss and the extreme caloric restriction—not from flushing toxins from our bodies."

While many studies focus on green tea, you can gain benefits from any variety. Find a variety you enjoy drinking, and keep in mind that there is a lot of flavor variation within each category.
Italian researchers found that drinking a cup of black tea per day improves cardiovascular function—and the more cups you drink, the more you benefit! Better cardiovascular function means you can breeze through that 5K you signed up for. And a study published in the Proceedings of the National Academy of Sciences revealed that drinking 20 ounces of black tea daily causes the body to secrete five times more interferon, a key element of your body’s infection-protection arsenal. Just make sure to ditch the dairy. A study in the European Heart Journal found that while black tea can improve blood flow and blood vessel dilation, adding milk to the tea counteracts these effects.
And Ian K. Smith, M.D. agrees. Dr. Ian is a Harvard graduate, founder of the SHRED Lifestyle, and the author several best-selling diet books. He explains that the liver, kidney, lungs, skin, and gastrointestinal system remove toxins that accumulate in the body. But following a detox diet full of natural foods can enhance the body's ability to cleanse. He adds, however, that dieters should make no assumptions about health when choosing a detox diet. "Detoxes have gotten very trendy, and many of them are unhealthy and quite dangerous."
