Researchers don’t know if increasing water consumption beyond two glasses would increase weight loss even more. That's something they’d like to study in the future. But the researchers caution against taking this strategy to extremes. While rare, it is possible to drink too much water, leading to a condition called water intoxication, which can make you quite sick.

Lawrence Cheskin, MD, director of the Johns Hopkins Weight Management Center and associate professor in the Department of Health, Behavior & Society at Johns Hopkins School of Public Health in Baltimore says this study adds to the body of evidence on this weight-loss strategy, which is helpful.

“I recommend that people fill up their stomachs with something that is zero calories and not just right before a meal but during the day as well,” Dr. Cheskin says. “Sometimes people just need something in their stomach to feel more satisfied. So this is in line with what I recommend. I’m not sure it needs to be water. In fact, that’s not many people’s favorite beverage. I don’t see any problem with it being diet soda or Crystal Light or something with very few calories because you can be filled up just as much or more with other things, too.”
