co worker hygiene

Sheila

I work with a guy who comes to work so smelly (to put it nicely). recently the general manager has made a post about work hygiene (he has diabetes and is over weight, everyone atvwork keeps making excuses that he smells the way he does because he diabetes.)I'm the kinda of person who takes a shower daily, sometimes twice a day. how do I kindly say something to him without him getting oftened?? I'm not sure were to post
