A TRIPLE PLATINUM COUNTRY SONGWRITER WANTS TO PERFORM ON STAGE, BUT KNOWS THAT CAN'T HAPPEN AT 417 POUNDS, ON ABC'S "EXTREME WEIGHT LOSS"

Country Music Stars Casey James and Gretchen Wilson + Olympic Gold Medalist Ryan Lochte Guest Star

"Jayce" (Nashville, TN) - Jayce grew up dreaming of becoming a famous musician. His father was a songwriter, but Jayce always dreamed of performing on stage. As a child, Jayce was dyslexic and struggled in school. Shy and introverted, he started overeating, weighing 175 pounds by the end of sixth grade and 320 pounds by the time he finished high school. By the time he ballooned to 417 pounds as an adult, Jayce knew it was time to ask for help, so he called upon the hit series "Extreme Weight Loss," in the episode airing TUESDAY, JUNE 17 (8:00-10:00 p.m., ET/PT) on the ABC Television Network.

Jayce got married very young. Though the marriage was good for the first couple of years, after having a son things took a turn for the worse. Jayce attributes his largest weight gain to his eventual divorce and the ensuing custody battles he continues to fight against his ex-wife to this day.

After his divorce, Jayce moved to Nashville to actively pursue his dream of becoming a musician. In his first year there, he wrote a song, "Country Boy's World," which was featured on country star Jason Aldean's album, "My Kinda Party." Aldean's album went on to become the top-selling country album of 2012. Jayce is currently one of the most in-demand songwriters in Nashville, but now he also wants to be the guy on the stage. However, he knows his current weight makes that dream physically impossible.

Determined to finally make his dreams come true and become a man his son can be proud of, Jayce reached out to Chris Powell to help change his life. Jayce will chase his dreams of finally being on stage, with help from surprise visits by country music stars Casey James and Gretchen Wilson.

Additionally, Chris will force Jayce to face his childhood fear of being in the water (he almost drowned at six years old) in an unbelievable swimming challenge with Olympic Gold Medalist Ryan Lochte.

New in Season 4, in addition to working with Chris and Heidi Powell, each participant spends the first 90 days of his or her weight loss journey at the renowned University of Colorado's Anschutz Health and Wellness Center (AHWC) in Aurora, CO.

Chris and Heidi, along with AHWC's medical director Holly Wyatt, MD, associate professor of medicine at the University of Colorado, guide participants on their journeys to safely lose up to half their body weight, ultimately revealing an amazing metamorphosis. The Anschutz Health and Wellness Center offers some of the country's most advanced research and science-based expertise, focusing on a comprehensive weight loss and weight loss management approach, including fitness, nutrition and wellness services.

"Extreme Weight Loss" is produced by Eyeworks USA. JD Roth, Todd A. Nelson, Matt Assmus and Brant Pinvidic are the executive producers.
