Efficacy of Organic Ayurvedic Products and green tea extract rich in Catechin Polyphenols and Caffeine lies in increasing 24-h energy expenditure and fat oxidation in humans.. Green tea extract is purported to enhance thermogenesis and enhance satiety. A study recently conducted, measured energy expenditure and fat oxidation in humans over a 24 hr period.
Subjects were given either 270 mg of green tea extract (90 mg, 3 times/day), 150 mg of caffeine (50 mg, 3 times/day) or a placebo. Subjects in the group supplemented with green tea extract had a significant 4 % increase in resting metabolic rate and a significant decrease in something called respiratory quotient (which means they were using more fat as fuel). Moreover, another recent study showed that those who drank more tea had a lower body weight and lower body fat than those who did not.
