Diuretics are substances that make you pee more, they make your body lose water. Beverages containing alcohol and caffeine are sort of accidental diuretics - that is, they're not drunk with the purpose of losing water but it happens anyway. Then there are substance that are taken with the explicit purpose of losing water.
Most studies have found that in moderate amounts, caffeine has only mild diuretic effects â much like water. One report, by a scientist at the University of Connecticut who reviewed 10 previous studies, appeared in June 2002 in The International Journal of Sport Nutrition and Exercise Metabolism.
