The Truth About Green Tea for Weight Loss

It’s hailed as a fat burner and a cure-all for cancer and heart disease Does it work, and is it safe?

Green tea has gained tremendous popularity as an all-around health elixir, touted to burn fat and prevent an array of illnesses, including cancer and heart disease

With enticing names such as “Green Tea Triple Fat Burner” and “Green Tea Slim,” many people are drawn to supplements of green tea for weight loss Consumers spent about $140 million on them in 2015, according to the latest data available from Nutrition Business Journal Meanwhile, tea, including green tea—made by steeping tea leaves or blending green tea powder in hot water—is the second most popular beverage worldwide, surpassed only by water

But is there scientific substance behind the claims that green tea is good for your waistline or your overall health? We reviewed the research and spoke to experts to find out

Will Green Tea Help You Lose Weight?

It’s true that green tea can raise your metabolic rate, so you burn more calories, says David Nieman, DrPH, director of the human performance laboratory at Appalachian State University in Boone, NC Nieman, who has studied green tea extensively, says this effect is probably due to a combination of its caffeine and catechins—antioxidants that are plentiful in green tea and present in smaller amounts in some fruits, dark chocolate, and red wine

But the effect is likely to lead to little, if any, change on the scale “People think if you drink a few cups of green tea, you’ll see the fat melt away,” Nieman says “That’s just not going to happen”

Even at large doses green tea's weight-loss effect is minimal For example, in a study published in the journal Clinical Nutrition in 2016, overweight women took either a daily dose of about 1,350 mg of green tea extract in supplement form (the equivalent of roughly 15 cups of green tea) or a placebo for 12 weeks While the green tea group dropped an average of 24 pounds, the women taking the placebo lost 44 pounds

What’s more, experts warn against taking the large amounts used in studies like this one—and recommended on many supplement labels There have been reports of serious liver damage in people who used green tea supplementsLIVE GREAT.

Still, when it comes to losing weight, working a few cups of brewed green tea into your diet isn’t necessarily a bad idea “Like coffee, green tea may give you a mild boost, and if you don't add sugar, it has no calories," notes Consumer Reports’ chief medical adviser Marvin M Lipman, MD "So drinking it in place of sugary drinks like soda can help you cut calories”

But don’t guzzle gallons of it Studies show that drinking three to five cups per day (up to about 40 ounces) is generally considered safe

Does Green Tea Prevent Cancer?

Catechins are also credited for green tea’s cancer-fighting potential These antioxidants have the ability to block the action of unstable molecules called free radicals, which can cause changes in healthy cells that sometimes lead to cancer But there’s no solid proof yet that the catechins in green tea help to prevent cancer in humans, despite some promising studies in test tubes and animals

In 2009 the Cochrane Library published a review of 51 studies that included a total of more than 16 million participants Each study investigated whether consuming green tea reduced the risk of developing specific types of cancer, including those of the breast, colon, oral cavity, liver, pancreas, and prostate

The results were conflicting, says lead author Katja Boehm, PhD, a health psychologist at Private University Witten/Herdecke in Germany After scrutinizing the data, Boehm says, the evidence of a benefit wasn’t strong enough to recommend using green tea to prevent cancer

Can Green Tea Prevent Heart Disease?

There’s some data to suggest that green tea can reduce the risk of cardiovascular disease—a narrowing of the arteries that can lead to heart attack, chest pains, or stroke Best of all, you don’t need to drink vast quantities to achieve significant benefits

For example, in a study of more than 40,500 adults, researchers in Japan found that those who had five or more cups of green tea per day were 26 percent less likely to die of cardiovascular disease over an 11-year period than those who drank just one cup per day

Similarly, a study of 76,979 people published in the Journal of Epidemiology and Community Health in 2011 found that women who drank one to six cups of green tea per day had a reduced risk of dying of cardiovascular disease (over an average of 13 years) compared with those didn’t drink any

How might green tea protect the heart? Experts say it may reduce high cholesterol levels and high blood pressure, both of which are important factors in causing cardiovascular disease

“These findings are intriguing, and there’s no harm in drinking reasonable amounts of green tea,” Lipman says “But it’s no miracle cure” To reduce your risk of diseases such as cancer and heart disease (as well as keep your weight in check), he says, you need to eat a healthy diet that includes plenty of fruit, vegetables, and whole grains You should also exercise and avoid smoking

"Green tea alone isn’t going to atone for bad habits," Lipman says, "and you certainly shouldn’t rely on it as the key to good health”
