I'm sorry if this thread seems silly, but I just have to get this off my chest. One liter of water weighs 2.2 lbs, so therefore if you have recently drank a whole bunch of water and then find you weigh more than you did yesturday, it could be why. I can easily drink 1 liter in a single sitting so my scale goes a tad up and down. I hope that helps anybody who worries about a couple of pounds difference from time to time. I know I've seen a few threads were people think they've put on weight when they may have not at all.
Peace Out,
Greg
