Green tea may aid in weight loss due to its caffeine and antioxidant content. Caffeine can boost metabolism and fat burning, while antioxidants like EGCG (epigallocatechin gallate) may help inhibit fat absorption and increase fat oxidation. However, green tea alone is not a magic solution for weight loss; it should be combined with a balanced diet and regular exercise for best results. Drinking 2-3 cups of green tea per day may provide a modest boost in weight loss efforts.
