Expert Insight
Drinking Cho Yung Tea is not a scientifically proven way to lose weight. However, regularly consuming beverages that contain green tea may help contribute to weight loss because of the action of the compound epigallocatechin gallate, a natural chemical in green tea that may increase the number of calories burned during normal activities. Still, professional health organizations strongly advise that the most effective weight loss strategy is to burn more calories than you consume by either decreasing the amount you eat or increasing your level of physical activity."
