Yes, in several ways. Drinking 500 ml of water before meals reduces calorie intake by 75-90 calories per meal. Water temporarily boosts metabolism by 24-30% for about an hour. Replacing sugary drinks with water eliminates hundreds of daily calories. Aim for your calculated daily target.

Cold water provides a very small metabolic boost as your body expends energy warming it to body temperature, but the effect is minimal (about 8 calories per glass). Drink water at whatever temperature you prefer — consistency matters far more than temperature.

Studies show drinking 500 ml (about 16 ounces or 2 cups) of water 30 minutes before meals can reduce hunger and calorie intake at that meal. This simple habit, combined with proper daily hydration, supports weight loss without any additional cost or effort.
