Green tea contains caffeine and catechins that are thought to boost our metabolism for several hours after drinking. Studies have found that one cup of green tea may not be enough to boost your metabolism though and it is thought that drinking between two to four cups of green tea may help you to get the boost you require.
Alternative: other tea that contains catechins and caffeine is oolong tea, which is a partially fermented tea (green tea is unfermented) that has a sweet taste."
