So people pay a whack of money that could be spent on bicycle bits to have an electrical charge run all round their body to tell them they may or may not have too much fat in their system?????
Isn't it cheaper to go touch an electric fence and then burn off the instant energy (and thus some of that maybe-maybe-not fat) that such an impulse would inspire?????
Call me a cynic, but sorry, I'm not convinced...
