TLC's hit show My 600-lb Life returned for Season 6 on Wednesday, and fans were introduced to Lee Sutton and Rena Kiser — a couple who met at a weight loss clinic and bonded over their love of food. "I remember meeting Rena for the first time. Her brother was my roommate at the bariatric clinic," Lee said in promotional footage. "And I kind of felt jealous how she would make sure what he needed."

Unfortunately for the pair, the clinic didn't allow relationships, so they left. After dating for 11 years and struggling with food, they essentially became immobile. Rena used to take care of Lee, but now his sister, Cassie, looks after both of them.

On last night's episode, Lee battled with bariatric surgeon Dr. Younan Nowzaradan. He originally ballooned to 714 pounds but successfully lost 168 pounds after the gastric bypass procedure, which shrinks the size of a patient’s stomach. After leaving the hospital, he only dropped 9 pounds on his own — but the doc was unimpressed, to say the least.

"What in the world is going on with you? You’re choosing to overeat and you think it’s okay?" Dr. Now asked. Lee argued that he's been vomiting, which is why he’s having problems with his weight. "That’s how it works," he said. "You throw up constantly because the surgery forces you to when you overeat now."

Lee quickly tried to defend himself, adding that he's afraid of being malnourished. "Do you look like you’re malnourished?" Dr. Nowzaradan clapped back. "You’re overeating, and whatever you’re overeating you’re throwing up. It means the surgery is working to hold you back when you make bad choices, and it’s the only reason that you didn’t gain 100 pounds these last two months." Yikes.

Back in November, Lee shared an update with family and friends via Facebook in November, saying he wasn’t allowed to post real photos of himself yet. Instead, he shared a drawing of himself with Rena saying, "We’re doing it!! 400 lb together." Amazing!
