Anyone who has watched TLC’s “My 600-lb Life” has probably noticed that every patient goes to the same surgeon: Dr. Younan Nowzaradan, who is called “Dr. Now” for short. One of those reasons is because he’s an executive producer on the show, but the other is because he was the first doctor in the Houston area to take on super-morbidly obese candidates who were previously considered inoperable.

Dr. Nowzaradan graduated from University of Tehran, Iran in 1970. He has nearly 20 years of experience in Laparoscopic surgery and six years of experience in Laparoscopic Bariatric surgery.

The doctor describes his program in the following way on his website: “Our comprehensive weight loss program is directed by Younan Nowzaradan, M.D., F.A.C.S., one of the most experienced and knowledgeable weight loss physicians. Dr. Nowzaradan is a general and vascular surgeon, that has been in practice in Houston, Texas for many years.”

Like in past seasons, he will be featured on Season 5 of “My 600-Lb Life.” He gets stern with one of the participant’s family members. “It doesn’t look like he lost any weight,” he says in the trailer from the new season. “You’re killing him!”

This season, one episode will show the weight-loss journey of twin sisters. The trailer shows that one of them suffers a medical emergency. “What’s wrong with my sister?” one of the twins yells as her sister is wheeled away on a hospital bed. “I love you, Kandi.” When Brandi, the other twin, is informed about her sister, she is told Kandi’s heart stopped and she might have brain damage.

Viewers of “My 600-Lb Life” can expect to see the subjects struggle with daily routines, like showering, overeating and ultimately their journey to hopefully losing hundreds of pounds.

Will all 15 participants get healthy in the end? Find out when Season 5 of “My 600-lb Life” premieres Wednesday, Jan. 4 at 8 p.m. EST on TLC.
