How Water Aids Weight Loss
She points out that folklore and everyday experience both have suggested that water promotes weight loss, but little scientific information has been offered on the topic.
This doesn't mean that good old H2O is a magic potion, but that drinking water may help people shed pounds for the simple reason that it has no calories and fills up the stomach, making people less hungry.
Davy says water makes people feel fuller, inducing them to eat less food. She also offers good news for those who prefer diet sodas and other drinks with artificial sweeteners, saying such liquid refreshment fills people up, too. But she advises against drinking beverages made tasty with sugar and high fructose corn syrup, which are high in calories.
Davy says no one knows how much water people should drink daily, and that the federal Institute of Medicine says healthy people can let thirst be their guide.
However, she recommends that women drink about nine cups of fluids every day, including water and other beverages, and men about 13 cups.
It is possible, she adds, to drink too much water, which can lead to a rare but serious condition known as water intoxication.
The study was funded by the Institute for Public Health and Water Research, a nonprofit, independent science and education organization.
This study was presented at a medical conference. The findings should be considered preliminary as they have not yet undergone the "peer review" process, in which outside experts scrutinize the data prior to publication in a medical journal.
