Personal trainer Chris Powell and his wife Heidi Powell are back for their fourth season of Extreme Weight Loss, and this time they are joined by Doctor Holly Wyatt, a nutritional expert.
Extreme Weight Loss is a documentary reality series that follows the lives of 13 dangerously obese men and women who train with Chris and Heidi in an attempt to lose a lot of weight over the course of a year in order to have healthier, happier lives. “We’ve totally changed the premise of the show,” Chris reveals. “I mean, before, I used to go out to actually live with out people. Now we bring them to us.”
