New research suggests that drinking water before meals can help you shed pounds.

Drinking waterProfessor Brenda Davy presented the results of a trial on water and weight loss at the American Chemical Society Meeting last month in Boston. She said:

"... we found that over the course of 12 weeks, dieters who drank water before meals, three times per day, lost about five pounds more than dieters who did not increase their water intake."

A previous study had found that middle-aged and older people who drank two glasses of water before eating a meal ate between 75 and 90 fewer calories during that meal. Professor Davy (from Virginia Tech), said it was the first randomised controlled trial looking at water consumption and dieting.

This new trial demonstrates that drinking two glasses of water before meals translates into greater weight-loss for people on a calorie-controlled diet.

The study involved 48 adults aged 55-75 years, divided into two groups. One group drank 2 glasses of water before their meals and the other did not. All of the subjects ate a low-calorie diet during the study. Over the course of 12 weeks, water drinkers lost about 15.5 pounds, while the non-water drinkers lost about 11 pounds.

Importantly, after the end of the low-calorie diet, water drinkers who continued the practice of drinking water before meals for 12 months, while eating well, were better at keeping the weight off.

Davy said water may be so effective simply because it fills up the stomach with a substance that has zero calories. People feel fuller as a result, and eat less calorie-containing food during the meal. Increased water consumption may also help people lose weight if they drink it in place of sweetened calorie-containing beverages, said Davy, who is with Virginia Tech in Blacksburg, Va.
