TLC's My 600-lb Life documents the journeys individuals undertake to escape obesity and regain control of their lives.
With the support of his fiancee, Kathryn, Robert turns to Dr. Nowzaradan in a desperate attempt to save his life. He tries to reverse a lifelong food addiction that has left him bed-bound, saddled with grotesque lymphedema and nearly 900 pounds.
Tamy's eating addiction has caused her weight to balloon over 500 pounds. She has become a hermit after years of shame, and hopes to restart her life so he can take better care of her son, Zachary.
