I've been talking about dropping 20 pounds for a decade and it hadn't happened. I run. I run marathons. I can't work out more and so I know it's diet and behavior change. Retrofit was the first time that I felt like there was something that fit within the way I lived.

The combination of the measurement, the real-time communication in terms of the portal, the structure, the feedback, the Skype calls that was with real people, rather than just something I had to follow, but in a way where I didn't have to be in a place. I could schedule it in my normal schedule. It was just another meeting that I had for 30 minutes sort of in the midst of everything else. The whole package really fit well and, of course, there were direct results.

The number of things I changed were very basic, relatively a small number. It was mostly applying some very discreet rules to certain eating patterns that I felt like were long-term sustainables. Pretty much everybody sees the physical difference right away. I mean, I'm a pants size down. You see it in my face. So, I get a lot of that very quick response, "You look good. You look like you've lost some weight."

I'm not getting the "Really, you run marathons?" anymore. The identification of me as somebody who's trying to run a marathon in every state and has run a bunch of marathons even though I'm still - I'm not this 150-pound, six-foot-two rail. People don't say, "Gosh that seems funny. How do you do that?"

Having a coach to help us, for me as an individual, figure this out has been super, super helpful and I never had had a coach. I didn't have somebody like Don helping me think about how to eat properly. I didn't have somebody like Brad who was able to talk me through what was going on in my brain that might be different than others that was a reaction to whatever happened when I was seven years old.

It's been very satisfying, emotionally rewarding, empowering, I mean all very positive sorts of feelings around that. Because I feel like it's too early to say I have mastery over this. I mean it's been less than a year. Check back in two or three years because at that point I'll feel like I really have mastery of it. But I have confidence I'm going to have mastery over it this time around. Whereas, every other time I ever thought about it, it was always like something in the future that maybe I would get my act together on someday.

It is kind of life-changing because you've been in this place where you really haven't known what to do and all of a sudden you do something that has a really positive and powerful feedback loop of success and you're like, "Wow." It's not that that wasn't that hard. It's just that it worked.
