Sipping on some "high-quality H2O" (as Adam Sandler would call it in The Waterboy) may help you lose weight, especially if you combine it with other weight-loss-friendly habits like exercise and a balanced diet.
No calories, carbohydrates, sugar, salt, or fat in water, unlike sugary sodas or sophisticated coffee drinks. Drinking it won't count toward your daily nutrient intake, which is great for weight loss.
Water is more than a calorie-free drink. Some studies suggest that drinking water increases metabolism, so your body burns more calories at rest.
One study in Nutrition & Diabetes found that drinking 16 ounces of water increases resting energy expenditure, indicating the body utilizes more calories.
In addition to burning calories during rest, water may help you lose weight. A Frontiers in Nutrition study found that fat breakdown requires enough liquids. Without adequate hydration, your body may have trouble using fat as fuel.
