For middle age and older adults weight loss is increased by drinking two glasses of water before eating.
Recent research has found that one can lose 30 percent more weight than those who did not drink before eating. Scientists at Virginia Tech in Blacksburg assigned 48 overweight or obese men and women ages 55 to 75 to one of two groups. Both groups consumed low-fat, low-calorie diets for 12 weeks, but one group was told to drink two 8-ounce glasses of water before breakfast, lunch and dinner.
After 12 weeks, the water drinkers shed about 15.5 pounds, while the other group dropped about 11 pounds. The two groups were followed for one year and those who continued to drink water before meals lost even more weight, on average about 1.5 pounds.
Water fills the stomach with a zero-calorie fluid, so people eat less. However this seems to work only for this age group , because the stomach releases the water much slower from the stomach.
The study was funded by the Institute for Public Health and Water Research, a nonprofit, independent science organization that was launched by an unrestricted grant from the Brita Products Company.
