Water Myth: I Should Drink Eight 8-oz. Glasses of Water Per Day
Water Fact: Your ideal amount of water depends on your diet, size, activity level and unique body chemistry, plus the climate where you live. "The standard amount of water is based on 1 ml per calorie burned,"says Julie Upton, MS, RD, CSSD, a sports dietitian with Appetite for Health. "If you burn 2,000 calories you need about two liters. If you burn 3,000 calories a day, you need about three liters."
