Previous research has shown that green tea has thermogenic or metabolism-boosting and anti-obesity properties. Therefore, Gabrielle Aparecida Cardoso and colleagues decided to study the effects of 8 weeks of green tea consumption with and without a weight lifting program on body composition (i.e., lean body mass versus body fat mass) and resting metabolic rate (RMR) in women who were overweight or obese.
This study showed that, compared to lifting weights alone, when combined with green tea consumption weight lifting leads to significantly greater increases in RMR, lean body mass, and muscle strength, in addition to significantly greater decreases in body fat, triglycerides and waist circumference. Consider adding a green tea supplement into your daily routine, but make sure you maximize its health-improving, fat-melting, muscle-building, and muscle performance-enhancing effects by hitting total body weight lifting workouts at least 2-3 times/week.
