One of the main ones is that it can aid in weight loss as there are components that helps the body to burn off fats and calories.

EGCG or Epigallocatechin Gallate is one of those antioxidants and it has properties to stimulate your metabolism and speed-up your weight loss efforts.

Based on a small study that was carried out, it seems as if green tea helps to speed up the oxidation of fat and raises metabolic rates, thanks to the thermogenic properties. This study involved healthy young males with lean to slightly overweight body. Each was assigned three random meals with one of three cures, the green tea extract with 50 mg of caffeine; caffeine in 50 mg capsule or a placebo capsule.

All the candidates were placed in a respiratory chamber that was designed especially for the study on three different occasions for twenty-four hours for the researchers to measure thermogenesis and energy expenditure. The ones who drank the green tea extract showed a 4% increase in the thermogenesis and an overall increase of 4.5% for energy expenditure.

Other research studies also show that diets with a lot of flavonoids are connected to a lower risk of severe disease, heart disease, stroke and cancer.
