Do you know that fat burner like Hydroxycut containes caffeine? Hydroxycut contains Garcinia cambogia which is a mixture of hydroxycitric acid and caffeine. Like that arh, by drinking coffee and drinking lime/orange juice (citric acid) every day can slim down already right? No need to worry about the side effects of hydroxycut. Actually, when I was dieting, I drank lime juice almost every day but not drinking coffee coz my body can't take the side effects of caffeine.
