This tea is a weight-loss ninja. The stem, fruit and root bark of the barberry shrub contains berberine–a powerful, naturally occurring, fat-frying chemical. A study conducted by Chinese researchers revealed that berberine can prevent weight gain and the development of insulin resistance in rats consuming a high-fat diet. Previous studies have also found that consuming the plant can boost energy expenditure and help decrease the number of receptors on the surface of fat cells, making them less apt to absorb incoming sources of flubber.

Another weight-loss tea bursting with ECGC? Green tea. The combo of caffeine and ECGC found in the tea has been found to help you lose weight and keep it off, per a meta-analysis on 11 studies in the International Journal of Obesity. It does have less caffeine than black tea, making it easier to sip any time of day without having an effect on your sleep later that night. (Check out these other astounding benefits of green tea.)
