Green tea plus exercise speeds the loss of tummy fat

January 20, 2009 | 11:02 am

Gtea1If reducing that abdominal paunch is part of your goals for the year, consider adding green tea to your diet. Several studies have hinted that green tea provides a boost to exercise-induced weight loss. Another study, published in the February issue of the Journal of Nutrition, supports that link and shows that tummy fat may be the first to go.

The study evaluated 132 obese adults. All consumed a diet that was consistent in daily calories and participated in 180 minutes a week of moderate-intensity exercise. They also drank a daily beverage containing 39 milligrams of caffeine, but one group consumed green tea with 625 milligrams of catechins, an antioxidant that is the main component of green tea. After 12 weeks, the participants drinking the green tea had greater loss, 4.4 pounds compared with just over 2 pounds in the control group. The green-tea group also had larger declines in total abdominal fat, subcutaneous abdominal fat and triglycerides.

How green tea works its magic is not completely understood, but scientists believe it speeds the rate at which fat is broken down in the body. It may also help the body's sensitivity to insulin, lowering the risk of diabetes. The study was conducted by researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University as well as research centers in Florida and Japan.

Another study on green tea, also featured in this issue of the Journal of Nutrition, shows that drinking plentiful amounts of the beverage over many years may have a subtle influence in decreasing the risk of breast cancer. The study examined almost 7,000 women, ages 20 to 74, in China. The women were evaluated for breast cancer incidence and consumption of green tea. Compared with nondrinkers, women who drank green tea had a slightly decreased risk of breast cancer. The benefit was strongest for women who drank the most green tea over longer periods of time.

Green tea is delicious...just remember that it should NOT be prepared with boiling water, which will scorch the tea and make it bitter. The heartier, darker green teas such as bancha, gemaicha, or hojicha can be prepared with water at about 180F, while the more delicate senchas should be prepared between 170-185F. Get your tea from a good supplier and pay attention to their instructions.

This really is a good news for me. I am searching for the ways to
shed some pounds. I like the idea of consuming green tea. How about using oats as breakfast for weight loss?

This is great, I love green tea!

What about drinking white tea? And does black tea and rooibos have any similar effect?

I associated the anemia I had last year to green tea, since the doctor haven't found any other reason for my disease. I also had insomnia. I stoped it and my health came back, but I've never lost weight drinking it. Why is it so?

What about gum with green tea like Nutra Trim? Do you need to drink greentea can you chew it also?

Interesting post! I drink a lot of Chinese and Japanese green teas. I was unaware of the fat loss benefits, but I usually make a large batch of green tea and drink it cold (iced green tea) while working out in the morning. I also like Yerba Mate!

I have mild acidity and in my case green tea increased irritation in stomach and intestine, need to be researched. In my case I even can not tolerate aspirin (which is also good blood thinner) In my opinion in general, things which are not sweet are good for obesity, diabetics, triglycerides, for example bitter guard is good for above mentioned things but I even can not tolerate high dose of it. Green tea is also kind of bitter thing it must be good for obesity, DB,TG so good luck to those who can tolerate it .

I wonder how you tell the catechin contents of Green Tea? And how many cups of green tea you need to drink per day? I know the article says they drank 625 mg. of catechins but is this in one sitting or can you spread out throughout the day

Okay i've been readin a lot about these green tea benefits of weight loss, but the only thingi can't figure out is what type of green tea should i drink to help me lose weight? I mean there are so many different types of them and brands. So which is the best one and most convenient to find it at a local store or a walmart?

It is very nice that this post shows the data of weight loss of green tea with exercise. I was looking for this kind of data. Thanks.

great site! I'm so glad I came across it. so many wonderful pieces of advice! exactly what a new person in this stuff like I need:) have used to find great blogs with useful pieces of information by http://torrents.rapid4me.com search engine, but always search for smth more. I really liked what your tutoial has to offer. Hopefully one day I will be in the possition to do stuff with drupal without looking up tutorials every step of teh way. thanks!

Green tea high blood pressure research, 17 studies show reduced blood pressure. Complete information on benefits and controversies.The caffeine content of green tea is low compared to other beverages and over the counter pills. Plus three things you need to know about caffeine in your daily green tea.

There are tons of ways to loose weight and knowing that tea is one of that. You may drink tea in its raw form but I prefer to mix a bit of lemon juice and honey to it so as to make the tea taste great. Also keep in mind that there is no restriction that you should drink tea only once per day; you can drink it as often as you want, and remember that the more you drink green tea, the faster you would lose weight.
