Really! I did NOT know that! I do remember a Biggest Loser season where ... I think his name was Eric but might have been Neil (it's been awhile) but he gained like 17 pounds before a weigh in. It was obviously water weight just over done... and he kept denying it. The denial instead of the admittance of game play turned me off the season, but still.... WOW! 1 pound! ok.. and good to know! thank you!
