Some studies have shown that an ingredient in green tea may aid weight loss, but there is no official evidence proving green tea burns fat as of 2014. However, there are many other health benefits that green tea is known to promote.
Green tea is rich with antioxidants, so the general consensus across the medical field is that the tea is highly beneficial to a person's health. Some experts have even called it the healthiest drink available. One of its antioxidants, epigallocatechin gallate, has been shown by some studies to boost metabolism, though others have shown no effect. Polyphenols found in the tea may also help break down triglycerides that decrease the amount of excess fat the body absorbs.
