Drink 2-3 cups green tea everyday as it helps in weight loss by increasing your metabolism.

According to study published in the American Journal of Clinical Nutrition, researchers found that men who were given a combination of caffeine and green tea extract burned more calories than those given only caffeine or plain water. More specifically, green tea extract resulted in a significant increase in energy expenditure (a measure of metabolism), and also had a significant effect on fat oxidation.

The proposed mechanism for green tea's calorie-burning properties lies in the ability of EGCG (a powerful antioxidant found in green tea) to increase thermogenesis, or heat production, by influencing enzymes in the metabolic process. This doesn't necessarily mean that you will feel hot after drinking green tea, rather it means that EGCG seems to increase the amount of calories burned throughout the day for all activities.
