My friend told me that a while back, and I was wondering if it actually had some truth, or if it was complete bs. We were talking about the best ways to gain weight and I said that he should just gain a bunch of water weight(as a joke), and he replied by telling me that water helps your system drain quicker and therefor makes you lose more (non-water) weight. I never drank all that much water, just when I was in the gym. Outside of the gym I ussually drink milk or gatorade.
Any truth at all?
