More studies are needed. There have been reports of them being linked to cases of liver failure and even death. Clinical studies show that up to 1. At higher doses, some people may experience headache, dizziness, and nausea. Overall, hepatotoxicity a. liver toxicity from green tea extracts is rare and can take months to occur.

Although one cup of green tea may raise your antioxidant levels, most studies have examined the benefits of green tea extract — which is a concentrated source of catechins. Green tea contains bioactive substances like caffeine and EGCG, which can have powerful effects on metabolism.

To burn fat, your body must first break it down in the fat cell and move it into your bloodstream. Animal studies suggest that the active compounds in green tea can aid this process by boosting the effects of some fat-burning hormones, such as norepinephrine noradrenaline.

The main antioxidant in tea, EGCG, can help inhibit an enzyme that breaks down the hormone norepinephrine 5. When this enzyme is inhibited, the amount of norepinephrine increases, promoting fat breakdown 6. In fact, caffeine and EGCG — both of which are found naturally in green tea — may have a synergistic effect 7.

Ultimately, your fat cell breaks down more fat, which is released into your bloodstream for use as energy by cells like muscle cells. Compounds in green tea increase levels of hormones that tell fat cells to break down fat.

This releases fat into the bloodstream and makes it available as energy. If you look at the label of almost every commercial weight loss and fat-burning supplement , you will likely see green tea listed as an ingredient.

Although most of these studies were very short in duration, some evidence suggests that the metabolism-boosting effect persists in the long term 15 , In one study in 60 obese individuals, those taking green tea extract lost 7.

However, not all studies show that green tea extract boosts metabolism. The effect may depend on the individual This would theoretically make you consume fewer calories automatically — and without any effort. However, studies produced conflicting results on the effects of green tea on appetite Some animal studies suggest that green tea extracts or EGCG supplements can reduce the amount of fat you absorb from foods, but this has not been confirmed in humans 20 , 21 , There is currently no evidence that green tea makes people eat fewer calories.

Some studies in animals suggest that it may reduce the absorption of fat from the diet, but human studies have not confirmed this. Although many studies show that people do in fact lose weight , there are also some studies showing no effect.
