According to this study, green tea could increase energy expenditure and fat oxidation in humans by 4%. The participants consumed green tea extract three times during the course of the day (with each meal), with each dosage containing 50mg caffeine and 90mg EGCG, for a daily total of 150mg caffeine and 270mg EGCG. This would be the equivalent of about 4 cups of green tea. An increase in energy expenditure was measured at 4%.
While this may initially sound promising, let's look at the bigger picture. First, the study was very limited because it included just 10 participants who were healthy males, were not obese, and the study lasted a short 24 hours. It is not known if the effects would be consistent if the study had last longer than 24 hours, or if the effect would taper off. It is not known what the results might be for overweight or obese women. Any long term weight loss benefit is based on theory, not results.
How much weight can you theoretically lose? Let's say your body needs 2,000 calories to maintain your weight. If drinking 4 cups of green tea can cause a 4% increase in calories burned, then you could burn 80 extra calories per day. This amounts to around 2,400 calories per month. Since you must burn 3,500 calories to lose one pound of fat, it would take almost a year to lose 8 pounds! This is a far cry from Dr. Perricone's promise of 10 pounds every 6 weeks. What if you drink 8 cups daily? Unfortunately, we don't know. The study was too limited to give us much information. It is probably not likely that you would benefit much from additional dosages, and consuming too much may not be good for you.
