Certainly, a change in the diet and more water consumption is always a surefire way to rid the body of odors but if that is not an option, shave your pits.

The crystal rock/stick is good but the best funk killer on the market is Certain Dry (formerly known as Certi-Dri). http://www.certaindri.com/Pages/CD_Home
