Hydration and Weight Management

Drinking enough water can support weight loss in several ways: it may boost your metabolism slightly, help you feel fuller before meals, and prevent mistaking thirst for hunger. Replacing sugary drinks with water is one of the simplest and most effective changes you can make for weight management.

Adequate hydration influences weight management through multiple mechanisms: water-induced thermogenesis (acute increase in energy expenditure of approximately 24% over 60 minutes after 500 mL intake), pre-meal water consumption reducing ad libitum energy intake by approximately 75–90 kcal per meal, and substitution of sugar-sweetened beverages reducing daily caloric intake. Hypohydration may also impair lipolysis via increased cortisol.

Hydration is a zero-cost, zero-side-effect strategy that complements any weight management plan. At Accord Medical, Dr. Joseph Wang includes hydration guidance as part of a comprehensive, sustainable approach to healthy weight loss.
