Is Water The Cure-All It's Reported To Be?
A new report says drinking water before meals will help you lose weight. But are there limitations in water consumption studies we should examine?By Ryan Biek | August 27, 2015
Water seems to get a lot of credit as a sort of cure-all, with a recent study promoting its use to lose weight. But should we be looking at water consumption studies a little more closely?
A study from researchers at the University of Birmingham in the U.K. found participants who drank 16 oz. of water before meals lost an average of nine pounds over 12 weeks, while the control group lost less than 2 pounds, on average.
The control group didn't drink water before meals, but its members were told to imagine feeling full. Though it's a small difference, it might be a confounding variable — a factor that could damage the validity of the experiment.
