Editor’s note: Two months ago, six CNN viewers began their quest to train for and compete in the Nautica New York City Triathlon alongside Dr. Gupta. The following is an email exchange between one of the participants – Rickey Williams – and our Fit Nation Athletic Director Laura Cozik.

I used to think I was addicted to food. That doesn't make sense though. We need food. I think I've discovered what my addiction was...COMFORT. I was addicted to comfort. It is what made me eat when I wasn't hungry. I was looking for comfort. It is what made me stay still when I needed to move. I'm realizing that is the main obstacle when I experience a lack in motivation for working out or eating healthy. These are the kinds of things I want to address during this challenge.

Last night I did a 75-minute run. There were countless times leading up to the workout that I was  uncomfortable with the thought of a 75-minute run. There were countless times during the run that I felt uncomfortable and wanted to stop. I finished. I was exhausted, but felt like a champion. I woke up this morning sore and "uncomfortable".

Stronger today than yesterday! Pulling for you guys today.

“Rickey, A 75-minute run??!! In early March??!! You're in good shape, I love it. So, so proud of you and thank you for wishing us all well today.
And thank you for sharing the "comfort" story. It's brave to admit such personal feelings. And truth be told, I've eaten for comfort many times.
The changes taking place are wonderful and inspiring. (Hope I don't sound too corny!) But keep in mind that with all the help CNN is providing you, you guys are still the ones out there gettin' it done! You should feel like a champion ”
