Water generated by internal metabolic processes of the body.
Water produced endogenously during catabolic reactions, particularly during the oxidation of macronutrients (carbohydrates, lipids, proteins).
Metabolic water is a byproduct of cellular oxidation reactions. The oxidation of one gram of carbohydrates produces approximately 0.6 ml of water, that of lipids approximately 1.1 ml, and that of proteins approximately 0.4 ml. Although the daily volume is low (approximately 200-300 ml), metabolic water contributes to the overall water balance. It is particularly important in situations where water intake is limited, such as during prolonged fasting or in arid environments. Production increases with energetic metabolism.
Contributes to overall water balance by providing an internal source of water.
Recognize that metabolic water alone is insufficient to meet hydration needs. Maintain regular intake of exogenous water for adequate hydration.
Metabolic water provides a minor but non-negligible contribution to the overall water balance.
