The show attracted dozens of reality TV hopefuls at the Boys and Girls Club in Venice on Saturday for the first run of auditions.
Casting directors conducted group interviews across the country to find the next set of individuals needing drastic changes.
"We even had a gentleman today who's almost 700 pounds here today, so unlike any other weight loss show in the reality world, this is definitely in a league of its own," said supervising casting director Brandon Nickens. "So it's an interesting day and people are excited about the opportunity to be on the show and work with Chris and get the weight off them."
It's not too late to audition, you can submit yourself online.
