Darren Kavinoky says he wants to help people empower themselves to make better choices.

“You know I think everybody goes through life being one of two things, either an example of what’s possible - or a warning of what’s possible,” says Kavinoky on Friday’s Dr. Phil.

The attorney, legal analyst, and host of Investigation Discovery's Deadly Sins says he struggled with weight and addiction issues before finding his success. Today he says he eats healthy, works out, and participates in triathlons. He’ll embark on a journey to run nearly 3,000 miles from Los Angeles to New York City to bring awareness to wellness-related causes.

“I feel blessed ‘cause I’ve been on both sides of that equation. And to be able to run across America and, and carry this empowering message that people can change and, and I believe change does happen in a moment.”

Kavinoky says he's dedicating the run to his good friend (and friend of Dr. Phil) Entertainment Tonight Senior Producer, Bonnie Tiegel, whom he credits with giving him his start in television. Ms. Tiegel passed away in January following a battle with cancer.
