Does green tea really burn fat, and will drinking green tea help you lose more weight? According to some research findings, consuming antioxidants found in green tea, especially catechins and the compound called EGCG, may promote metabolic health and modestly prevent weight gain. When 11 studies and articles were included in one 2009 meta-analysis that was published in the International Journal of Obesity, researchers found that “catechins or an epigallocatechin gallate (EGCG)-caffeine mixture have a small positive effect on weight loss and weight maintenance.” (12)
There are mixed opinions about how much green tea one should consume. The reality is one cup of green tea isn’t enough to affect your health. Some believe 2 cups of green tea will show benefits while others say 5. Some people say up to 10 cups is ideal but if you’re concerned about spending a lot of time in the bathroom you can add a green tea supplement to your diet.
Green tea also seems to boost physical performance, increase exercise endurance, and decrease reaction time, and there are many, many such studies showing these effects from caffeine, although other ingredients in green tea may aid this effect. Caffeine, and green tea’s, ability to mobilize fatty acids in fat tissue to make them more easily available for use as energy also seems to aid physical performance. In one study, caffeine was shown to significantly increase physical performance (exercise endurance and exertion). The antioxidants in green tea may also help prevent tissue damage during physical exertion as well.
Green tea is processed using either artisanal or modern methods. Sun-drying, basket or charcoal firing, or pan-firing are common artisanal methods. Oven-drying, tumbling, or steaming are common modern methods. Processed green teas, known as aracha, are stored under low humidity refrigeration in 30- or 60-kg paper bags at 0–5 °C (32–41 °F). This aracha has yet to be refined at this stage, with a final firing taking place before blending, selection and packaging take place. The leaves in this state will be re-fired throughout the year as they are needed, giving the green teas a longer shelf-life and better flavor. The first flush tea of May will readily store in this fashion until the next year's harvest. After this re-drying process, each crude tea will be sifted and graded according to size. Finally, each lot will be blended according to the blending order by the tasters and packed for sale.
Koicha, or thick tea, requires significantly more matcha (usually about doubling the powder and halving the water): approximately 3.75 grams (amounting to 3 heaping chashaku scoops, or about one teaspoon) of matcha and approximately 40 ml (1.3 oz) of hot water per serving, or as many as six teaspoons to 3/4 cup of water. Because the resulting mixture is significantly thicker (with a similar consistency to liquid honey), blending it requires a slower, stirring motion that does not produce foam. Koicha is normally made with more expensive matcha from older tea trees (exceeding thirty years) and, thus, produces a milder and sweeter tea than usucha; it is served almost exclusively as part of Japanese tea ceremonies.

In 1772, Swedish naturalist Carl Thunberg noted, "the country people made tea" from a plant related to rooibos or redbush. Traditionally, the local people would climb the mountains and cut the fine, needle-like leaves from wild rooibos plants. They then rolled the bunches of leaves into hessian bags and brought them down the steep slopes using donkeys. The leaves were then chopped with axes and bruised with hammers, before being left to dry in the sun.
• In skin cancer studies, lab animals that were given green tea developed 1/10th as many tumors as animals that were given water. The EGCC in green tea inhibits the production of urokinase, an enzyme that cancer cells need in order to grow. It also seems to stimulate the process of programmed cell death, or apoptosis, in cancer cells. Pair your green tea with these 30 foods that help prevent cancer.
If not taken with sugar, the alkaline nature of green tea helps reduce the blood glucose level. Moreover, the antioxidant and astringent qualities of green tea ensure good health and better functioning of the pancreas. Improving the function of the pancreas means a more efficient and regulated secretion of insulin and the subsequent improvement in decomposing and absorbing of sugar. This increase in effective functions can help prevent the onset of diabetes.
Green tea leaves are initially processed by soaking in an alcohol solution, which may be further concentrated to various levels; byproducts of the process are also packaged and used. Extracts may be sold in liquid, powder, capsule, or tablet form. Decaffeinated versions are also available. Green tea extract supplements are accessible over the counter in various forms.
A University of Miami study found that even a mild dose of green tea’s antimicrobial and antioxidant compounds erased almost two-thirds of pimples from people with mild to moderate acne when used twice daily for six weeks. To benefit, make a cup of green tea, let cool, and use as a face wash, or lay the tea bag directly on the skin to act as a compress for particularly bad pimples. For oily skin, mix peppermint tea with the green tea for an oil-blasting wash. Check out more teas that also work as acne home remedies.
Detox teas that combine caffeine with diuretics can trigger the loss of water weight. Just two cups of water weighs one pound on a scale, so shedding fluid can make you look and feel lighter–even if you haven't lost an ounce of body fat. Detox teas can also trigger a laxative effect, which causes your body to eliminate waste from your GI tract, another result that can make your stomach flatter, and allow you to feel lighter, even if your lean-to-fat ratio remains exactly the same. If this quick-fix effect gives you the confidence boost and motivation you need to start eating healthier and working out–the real keys to getting healthy and lean–terrific (assuming the teas are even safe to drink–see below). Just remember: If you go back to your former less-than-stellar eating or exercise habits, or stop drinking the tea, you can gain the weight right back just as quick as you dropped it.
There are three main varieties of tea: green, black, and oolong. All three varieties are made from the leaves of the same species of plant called Camellia sinensis; the difference is in how the tea leaves are processed. Green tea is made from unfermented leaves, while oolong tea is made from partially fermented leaves and black tea is fully fermented.
