Replacing caloric drinks with water leads to eating less calories throughout the day. In some groups drinking water has also been shown to cause higher energy use (energy expenditure) and fat burning (fat oxidation). This doesn’t mean water will lead to fat loss though, as high quality studies measuring WEIGHT are lacking (1). Although results aren’t consistent (3, 4), one study showed that drinking 500 ml water before meals and during meals doubled weight loss in the tested group! (5).
