Briefly:

I've seen Dr Westman in his Durham practice a number of times, mostly during my actual weight loss phase. He was very interested in the IF approach I was trying, which at the time was still pretty new-ish. I'd already lost a lot of weight and he asked me to come speak with his group, but I'm a serious introvert.

Anyway, I won't pretend to know him beyond a doctor/patient relationship, but he seemed like a genuinely good guy who was just trying to figure out the puzzle, like the rest of us.
