TLC Sets ‘My 600-Lb Life’ Premiere, New Series ‘Skin Tight’ (Exclusive Videos)

TLC has set a January 6 return for the fourth season of its reality series “My 600-lb Life,” which will be accompanied by the debut of new series “Skin Tight,” TheWrap has learned.

Each hour-long episode of “My 600-lb Life” tells the story of one morbidly obese individual — many who are home bound, relying on care just to live day-to-day — as they make the decision to undergo gastric bypass surgery.

The popular series documents the life-saving, but traumatic experience of surgery, the ups and downs of struggling with addiction and dependence, and the inevitable impact that change has on personal relationships.

“My 600-lb Life” Season 4 will premiere at 9 p.m. ET on TLC, followed by “Skin Tight” at 10 p.m.
