Green tea, unlike black and oolong tea is not fermented, so the active ingredients remain stable in the herb. It helps regulate blood sugar and insulin levels. A study with overweight and obese people found that drinking a beverage containing 625 mg. of green tea catechins helped increase exercise-induced weight loss especially in the abdominal area.
