I personally DONT think that a KID would make weight all day long... Have u ever been to a kids tournament. If 16 onces of water equal one pound then how much water could you drink. The concession stand make a killing off of gaterade, pizza, and prob the only think the kids could buy to NOT make them gain much weight during a tournament is CANDY.

I know one think we do after weigh ins at every tournament is drink a mix of water / gaterade eat a bagel and some fruit then chill for about 30 minutes and repeat.

It will take a lot to convince me that someone isnt gonna gain weight by drinking water etc. on a tournament day... Keep in mind that tournaments can be an all day event.
