According to a study, overweight individuals who drank 2 glasses of water before breakfast, lunch and dinner lost 5 pounds more than those dieters who did not increase their water intake before meals. This test group of dieters was able to sustain the weight loss even after a year. The dieters were allowed to have a balanced diet as per the calorific requirements for that age group. After 3 months, those dieters who had 16 ounces of water before every meal lost 15 pounds whereas those who did not drink water before meals lost 11 pounds. The reason for this could be simple- water fills the stomach, dilutes the stomach acids, and leaves one feeling less hungry. With less hunger, we tend to eat less, and hence there is weight loss. The dieters who drank water actually consumed 75 calories less than the nondrinkers. When calculated over the course of one year, this is a significantly lower calorific intake.
