Clinical trial confirms effectiveness of simple appetite control method

Scientists have shown that if any one who wants to win the "battle of the bulge" will win if they drink just two 8-ounce glass of ordinary water before meals. It requires no prescription, very cheap and is an appetite control agent. It has no common side effects. The entire affair looks too good to be true
Scientists today reported results of a new clinical trial of the weight-loss elixir at the 240th National Meeting of the American Chemical Society (ACS).
"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 pounds 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.
The study included 48 adults aged 55-75 years, divided into two groups. One group drank 2 cups of water prior to 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.
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.
Diet soda pop and other beverages with artificial sweeteners may also help people reduce their calorie intake and lose weight, Davy said. However, she advised against using beverages sweetened with sugar and high-fructose corn syrup because they are high in calories. A 12-ounce can of regular soda pop, for instance, contains about 10 teaspoons of sugar.
Davy noted that that nobody knows exactly how much water people should drink daily. The Institute of Medicine, an agency of The National Academies, which advises the Federal Government on science, says that most healthy people can simply let thirst be their guide. It does not specify exact requirements for water, but set general recommendations for women at about 9 cups of fluids — from all beverages including water — each day, and men at about 13 cups of fluids.
And it is possible to drink too much water, a situation that can lead to a rare, but serious, condition known as water intoxication, Davy pointed out.
The Institute for Public Health and Water Research, a non -profit, independent science and education organization whose mission is to improve public health through the consumption of quality drinking water, funded the study.
