A study based on several years of data, published in the Journal of Human Nutrition and Dietetics, showed that increasing water consumption by one to three cups a day decreased total calorie intake by between 68 and 205 calories. Intake of sugar and cholesterol were also reduced as a result of drinking more water.

Some physicians believe that drinking more water before sitting down for breakfast, lunch or dinner will curb the appetite. With other benefits such as better brain function, improved digestion and the ability to maintain energy levels, the old adage of drinking eight to ten glasses of water a day just may be more appropriate than ever.
