"Phat" once meant cool. It didn't mean fat at all.
"Phit" was coined by a client of mine who taught middle school students. I thought it was clever and worth keeping.
Being Phit allows you to think about indulging occassionally and being healthy.
American women will at some point step onto a slippery slope toward endless empty calories and stretchy pants.
Others are genetically pencil thin, or gym-rats who work out two hours per day (I was the latter in my 20's and 30's).
Phit seems to be a good word that describe those of us who want to be healthy, but have full lives.
Phit is about living wellness and living well.
