“There is very little evidence that drinking water promotes weight loss; it is one of those self-perpetuating myths,” said Beth Kitchin, Ph.D., R.D., assistant professor of nutrition sciences. “I’m not saying drinking water isn’t good; but only one study showed people who drank more water burned a few extra calories, and it was only a couple of extra calories a day.”
Kitchin says another water myth is the consumption rule: eight 8-ounce glasses of water per day.
“Yes, people do need to get fluids; but it does not have to be water,” Kitchin said. “There’s no evidence that it melts away fat or makes you feel fuller, so if you don’t like water it’s OK.”
