Excellent post by Amy. She's a beauty. I was lucky enough to be at that presentation she mentioned in the post, and it was a real a-ha moment for me. The PFT concept makes such good sense. It helps dispel the "if you're fat, you're unhealthy (and immoral) /if you're thin, everything's fine" myth. It has always driven me bonkers when body fat is blamed for metabolic problems, instead of being seen as a symptom that not everyone with the same metabolic problems will necessarily have.

I just now found Dr Naiman's site, and I'll probably be geeking out there all weekend.
