1000-Lb Sisters co-star Chris Combs has become a fan favorite, and he may even steal the spotlight from his famous sisters. The show is supposed to be about the weight-loss journeys of 37-year-old Amy Slaton and 38-year-old Tammy Slaton, but their other siblings participate in the show, including 44-year-old Chris. Like the rest of his siblings, Chris has gone on an incredible weight-loss journey since the show premiered in 2020.
