Total body water represents approximately what percent of body weight in typical adults?

Explanation:
Total body water in a typical adult is about 60% of body weight. This figure comes from the balance of water in lean tissues: roughly two-thirds of TBW is intracellular (about 40% of body weight) and one-third is extracellular (about 20% of body weight). This 60% benchmark is a standard reference used in fluid and nutrition calculations for average adults. In practice, TBW varies with sex, age, and body composition—men generally have more TBW than women, TBW declines with age, and infants have a much higher percentage.
