i have one of those fat percentage body machines, the one where you hold it and gives u a close measuremnt of your fat percentage, it send s down a small electrical shock in your body. I sit true if the more amount of water you have in your body the higher your fat percentage goes up, becasue i hear that the water conducts the electricty making your fat percentage go up. I'm 11% fat and then one day i had a big fruit salad, i measured it and went up to 15%!!!!!
