As of 2015, research has not proven that green tea promotes immediate weight loss. Studies do demonstrate that the properties of green tea may assist with weight loss by increasing fat oxidation and energy expenditure, states Everyday Health
Researchers believe that the active ingredient in green tea, epigallocatechin gallate, may help promote weight loss, states WebMD. However, some research demonstrates that drinking green tea reduces body weight and body mass index in overweight people, whereas other research studies suggest it does not.
Green tea is a good choice while on a weight loss diet as it is a healthy beverage to choose over high-sugar drinks and is considered to be a superfood, states WebMD. To gain the maximum benefits from green tea, it is recommended to use brands that use all natural ingredients and are free from artificial preservatives, explains Woman’s Health.
