Green tea influences metabolism due to its high content of catechins, specifically epigallocatechin gallate (EGCG), which can enhance fat oxidation. This means it may aid in weight management by increasing the number of calories burned during and after exercise. Regular consumption of green tea may also lower blood lipids and improve overall metabolic health. While it may not be a miracle solution for weight loss, it can complement a healthy lifestyle when combined with proper diet and regular physical activity.
