After morbidly obese people lose hundreds of pounds using methods ranging from gastric bypass surgery to strict dieting and workouts, there is still a constant reminder of their once much heavier selves. "Skin Tight," a companion series to TLC's popular "My 600-Lb. Life," presents profiles of people who go through extensive surgeries to remove up to 50 pounds of excess skin. Hourlong episodes introduce a variety of candidates who can't achieve personal fitness goals or have intimate relationships, and many feel even more uncomfortable than when they were obese. Using modern technology and reconstructive surgical options, massive amounts of skin are removed, creating a full-body transformation. The reveals not only improve each subject's self-image but also change lives forever.
