Tea

Tea contains a type of flavonoid called catechins, which could speed up fat breakdown and increase metabolism. In addition, the caffeine in many teas boosts calorie burning by increasing energy use.

The combination of these two substances is probably ideal for any weight loss strategy. Tea can help you maintain your weight loss by reducing the metabolism slowdown that occurs after losing a few pounds. Oolong and matcha green tea in particular may boost fat oxidation and help in calorie burning when used in conjunction with an exercise program. Oolong and green teas may also improve how efficiently your body uses fat that has been stored as energy, which might result in a 17% increase in your ability to burn fat. However, results may differ from person to person, much like with coffee.
