Has the long-sought magic potion in society’s “battle with the bulge” finally arrived? An appetite-control agent that requires no prescription, has no common side effects, and costs almost nothing? Scientists report results of a new clinical trial confirming that just two 8-oz glasses of the stuff, taken before meals, enables people to shed pounds. The weight-loss elixir, they told the 240th National Meeting of the American Chemical Society (ACS), is ordinary water.
“We are presenting results of the first randomized controlled intervention trial demonstrating that increased water consumption is an effective weight loss strategy,” said Brenda Davy, Ph.D., senior author on the study. “We found in earlier studies that middle aged and older people who drank two cups of water right before eating a meal ate between 75 and 90 fewer calories during that meal. In this recent study, we found that over the course of 12 weeks, dieters who drank water before meals, three times per day, lost about 5 lbs more than dieters who did not increase their water intake.
“People should drink more water and less sugary, high-calorie drinks. It’s a simple way to facilitate weight management.”
Davy pointed out that folklore and everyday experience long have suggested that water can help promote weight loss. But there has been surprisingly little scientific information on the topic. Previous studies hinted that drinking water before meals reduces intake of calories. Lacking until now, however, has been the “gold-standard” evidence from a randomized, controlled clinical trial that compares weight loss among dieters who drink water before meals with those who do not.
