It is recommended to drink about 1.5 liters of water a day* (2) to maintain the water balance. Moreover, it would seem that drinking water is positively linked to healthy eating habits. Thus a study on 4755 adults (3) has shown that those who drank about 1.5 liters of water a day ate more fruits and vegetables and consumed 194Kcal less than those who drank less. A recent major analysis (4) concentrated on the impact of water intake during or before meals. It would appear that compared to other drinks, drinking water goes hand in hand with a lower intake of calories during meals. The authors stress the potentially important role of water intake in reducing energy intake, and consequently in preventing obesity.
