“My 600-lb Life” averaged 1.4 million total viewers over the course of its third season, which can currently be seen via encores airing weekdays at 11 a.m. ET on TLC.

Each hour-long episode tracks a year in the life of one morbidly obese individual looking to overcome life-long emotional and physical struggles. To help get there, the subjects undergo gastric bypass surgery. Still, they must deal with the highs and lows of struggling with addiction in hopes to reclaim their independence, mend relationships with friends and family and renew their sense of self-worth.
