Drinking water before a meal reduces calorie intake in older men, but not younger people

Older, healthy, non-obese people -- mostly older men -- who drank water before a meal, ate 15 percent fewer calories than drinking no water according to a new study from researchers at the Virginia Polytechnic Institute and State University. Drinking water did not reduce calorie intake in younger people. Calorie intake
Older people drinking water before a meal ate 624 calories compared to 682 calories for those not drinking water.
Younger people consumed a similar amount of calories with or without water—913 calories versus 892 calories.
Men and women were told to drink 17 ounces and 12 ounces of water, respectively, thirty minutes before eating.
The age of the subjects were 21- to 35-years-old (younger) and 60- to 80-years-old (older).
Comment: Other research suggests to me that drinking water before meals does not have much effect on long-term body weight.
