There is some research suggesting that adding capsaicin and green tea to your diet could quash your hunger and cut your calorie intake. The reason is because capsaicin in stimulating to taste buds, and may help you from overeating. Adding capsaicin and green tea to your diet may rev up your metabolism without adding too much caffeine.
Oh, and for what it's worth, the research didn't say you had to mix the hot peppers in your tea. Whew!
I'll take my green tea with some passionfruit and apricots, thank you!
