Green Tea?!!?

Caffeine doesn’t stunt your growh. I drink tons of caffeine, and I’m 5’9…

I’ve never heard of green tea burning fat, though…

There is no caffeine in green tea. I can HELP you to burn fat, and you can drink up to 8 cups a day … but do not drink 8 cups of water, too … use the ‘green tea’ in place of the water when you are trying to drink 8 eight ounce cups of water in one day. It’s more ‘effective’ if you drink it before (RIGHT before) you eat, because your stomach will be ‘fuller’ from the water, so you won’t eat as much. You’ll still need to watch your caloric intake, and get good exercise … green tea is a good ‘antioxidant’ that can help you ‘get healthy’ but it is NOT going to ‘burn your fat off’ unless you ‘help it’ with some hard work of your own.

I’m not sure if it burns fat, but I know for sure that you can drink green tea at any time of day. If you’re afraid that the caffeine will stunt your growth, then minimize the amount of green tea you drink every day/week/year.

Studies relating to green tea and weight loss

I went looking for studies that would either support or disprove green tea weight loss. Contrary to some critics, I found both studies in the animal AND human model that are very promising.

Animal studies are currently used by mainstream science for leads as to whether something is worth proceeding to human studies on. There are a lot of drawbacks to animal studies, one of the main ones (aside from the pain caused to the animal) is that for different species of animals, you get different results. And that can lead to false conclusions as to whether what is being studied, like green tea weight loss, is effective.

There were a number of studies done with humans in relation to green tea weight loss, however.

Firstly, the green tea and weight loss studies in animals (mice)

The University of Chicago’s Tang Center for Herbal Medical Research on epigallocatechins (EGCG) (which are part of green tea) – shows blood levels of glucose (sugars), lipids (fats), and cholesterol are reduced. And fat deposits under the skin and in the abdomin are also reduced.

another green tea weight loss study described in the health section of the msn site also found that green tea extract improved the metabolism of glucose and lipids, which is beneficial for weight loss

there have been a number of green tea weight loss studies done on the ability of green tea extract to lower blood sugar. This relates to our metabolism, energy levels, insulin production and hence could be useful to the dieter in terms of cravings, and maintaining their energy levels.

But what about studies that support weight loss with green tea in humans?

In this particular green tea weight loss study, oolong tea or green tea extract (an extract is more concentrated than just drinking it on its own) resulted in an increase in energy used by the body of 3-4% (on average). The Linus Pauling Institute say this effect of green tea weight loss is “apparently due to increased fat oxidation and thermogenesis”. Thermogenisis refers to energy used in heat production that is not related to resting metabolism or physical activity. (our bodies use energy even when we’re doing nothing. It’s less than energy used in other activities, of course).

In another study, different groups of people were given caffeine, to see how that compared to green tea in thermogenesis. And people taking the green tea had higher thermogenesis than those taking the equivalent amount of caffeine without green tea catchetins.

Green tea does contain caffeine, but you can get herbal preparations without the caffeine. The good news for people who don’t like caffeine, is that it is the catchetins that produce green tea’s thermogenesis effects, not the caffeine.

So green tea weight loss can help dieters (not just mice 🙂 ).

There have been no studies done on long term green tea weight loss. And like any product that has a beneficial effect, there’s no use using it and then living on junk food. That would counteract some of the green tea weight loss benefits. The more odds you give your body by following a healthy slimming diet (like the Zone diet), the more successful you’ll be.

Other elements to ensure your long term weight loss success might be to start a high repetition, low intensity weights program, or exercise like walking (not aerobics – its good for your circulatory system and your heart, but not weight loss.)

Personally, I think the effects of green tea weight loss combined with its superb health benefits for blood sugar, cholesterol, bad breath, dental cavities, antioxidant effects, and potentially anticarcinogenic (promising studies in mice), make it a good adjunct to any weight loss program.
