green tea promotes weight loss
The rise in green tea's popularity in recent years could be because of its potential role in weight loss. (Although black tea is the most popular - it accounts for about 84% of all tea consumed - green tea is reported to be growing at a much higher volume than black.) Several studies have suggested that the flavonoids and caffeine in green tea can help elevate metabolic rate, increase fat oxidation and even improve insulin activity.
One study showed that people who consumed green tea and caffeine lost an average of 2.9 pounds during a 12-week period, while sticking to their regular diet. Another study suggested the increase in calorie output was equal to about 100 calories over a 24-hour period.
You don’t need to drink a lot of green tea to help you lose weight. While weight loss benefits vary based on different dynamics, they have been found by drinking as little as 2.5 cups of green tea per day.
