in the army, if you are too fat, they tape measure you to make sure you are in the army standards and a know alot of those dudes would put hemroid cream all over their abs and sides and wrap in saran wrap the ngiht before and they claimed it pulled all the excess water out. i dont know. its easier for me to maintain than to suddenly need to lose all that fat.
also, same applies to those sauna warriors who sit in there for 2 hours thinking they are losing weight that they wont gain back as soon as they drink water.
