Marla McCants became one of the most unforgettable faces to appear on My 600-lb Life. At her heaviest, she weighed over 800 pounds and was unable to walk, with her life hanging in the balance. Desperate for change, she joined the show—and years later, her journey stands as one of the most dramatic transformations ever seen. Today, she has lost more than 500 pounds, and her progress is nothing short of extraordinary.
Maintaining a healthy lifestyle isn’t always simple. Between family responsibilities, busy schedules, and the rising cost of nutritious food, sticking to a balanced diet can feel overwhelming. Fast food, while convenient, often becomes an easy trap—something that might feel harmless in the moment but can take a serious toll over time. That’s why experts constantly emphasize the importance of exercise, proper nutrition, and mental well-being.
While fitness influencers often dominate the conversation around health, stories like Marla’s carry a different kind of power—one rooted in resilience, struggle, and real-life change.
Years ago, Marla appeared on My 600-lb Life weighing over 800 pounds, facing a critical health crisis. Her condition had deteriorated to the point where survival was uncertain. But with determination—and the guidance of Dr. Younan Nowzaradan, widely known as “Dr. Now”—she began turning her life around. Today, her transformation is nothing short of remarkable.

Even after joining the show, the road ahead was far from easy. When Marla first met Dr. Now, he had doubts about whether he could truly help her.
Over the years, he has stepped away from patients when progress seemed impossible.
“There have been a few patients I felt I could no longer help,” he told People.
“I will always be available if they need me. If they won’t stick to the program, at some point, I can longer help them and they are taking resources from someone else who needs it.”
At her lowest point, Marla was bedridden, unable to stand, and relied entirely on others. She even cooked and ate in bed, using a fryer kept within reach. Her relationship with food had become a serious addiction—one of the hardest battles to overcome.
Determined to change, Marla relocated to Houston, Texas, with her daughter Sierra to work closely with Dr. Now. She underwent gastric bypass surgery, a major step in her weight-loss journey—but recovery proved complicated.
Didn’t want to cooperate
During her hospital stay, tensions rose. According to Dr. Now, Marla struggled to follow instructions and refused to stand as part of her recovery process. Eventually, she was discharged.
In an interview with Houstonia Magazine, Dr. Now emphasized that his work is driven by purpose rather than profit.
“Looking at the moral obligation that we’ve got, you see somebody who has no life who could have a life,” he said.
“We don’t need to be rich. We do make a living, but we don’t need to worry about making a living out of every patient we see.”
He also made it clear that cameras never influence his approach to patients.
“I never let the camera change my behavior toward any patient,” Dr Nowzaradan explained. “I do exactly the same thing if the camera is there or not.”
Speaking to People, Dr. Now admitted that long-term success isn’t guaranteed—even after surgery.
Dr. Now: ‘Necessary with tough love’
“It’s a daily challenge to work with some patients that can be self-destructive,” he said.
“My job is not to get aggravated, but to find a way to motivate them to work hard to get to their goals. There are times where I think it’s necessary for some tough love and I have to be stern with them, so I show some of my concern and frustration.”
He added, “Even during those times, my job is to find a way to work with them to get their weight to a healthy place. They are the patient because they need help and it’s my job to help them no matter what.”
Marla’s journey nearly ended after her discharge—but her daughter Sierra refused to give up. She reached out again to Dr. Now, asking for another chance.
Stood up for the first time in years
In a follow-up episode, Marla was still largely confined to her bed, depending heavily on her daughter. However, she had already made significant progress, dropping to 534 pounds.
Her next goal was skin removal surgery, but she still needed to lose more weight to qualify.
Setbacks remained. Marla struggled with cravings and occasionally strayed from her diet. Standing and walking—basic movements for most—were still major hurdles.
“A couple of months ago, I was kind of depressed because things weren’t going as I thought they would go, but it is getting better,” she said. “I’m getting stronger.”
Her ultimate goals were simple yet powerful: stand up, walk independently, and reclaim her life.

“I came to Texas so I can get my life back and be here for my grandkids, but I still don’t feel like I am able to be in their lives like I should. So I can’t wait to get that surgery done,” she said in the follow-up episode.
“I still have cravings, miss fried chicken,” she added. “I was trying to find a way that I can eat that. I tried using olive oil, but it doesn’t taste the same, and just eating meat is a little frustrating.
‘”All I can say is that I am human. You don’t have to starve yourself; you just have to make better choices.”
Meanwhile, Sierra began thinking about her own future after years of caring for her mother.
“I feel frustrated because if she can just get up and walk, that would be a major step for me,” Sierra said.
“I know right then and there—boom—I could just take off with my life.”
“A couple of months ago, I would have said it was frustrating sitting in this bed watching people come and go, but use that as fuel now because soon I will be out there,” Marla explained.
“I am going to the doctor’s soon, and I am hoping he will give me the go-ahead to get skin surgery.”
Claims of faking the production
Despite her progress, Marla later made surprising claims about the show’s production. In a YouTube interview with Rickey Smiley, she alleged that certain scenes were manipulated to heighten drama.
“Like, the scene where I was in the hospital. And I wouldn’t get up. You all don’t know why I didn’t get it up. First of all, they put it out there a year ahead, when actually it was only one month after I had the gastric bypass,” Marla explained.
“I had lost seventy pounds the first month. I had my surgery February 13th of 2015; that episode aired March of 2015. So I had just lost seventy pounds. I was malnourished, I was in the hospital, and he wanted me to get up? Seriously? I’m bleeding on the bed and you want me to get up?”
This is Marla McCants today
So where is she now? Marla has completely transformed her life.
In 2019, she appeared on Sister Circle and revealed that she had lost an astonishing 580 pounds.
“I never want to go back to that place,” McCants said on the show. “The way I was treated. I never want to go back there. It’s lonely.”
Even after her success, she continues to speak openly about food addiction and the stigma surrounding it.
”I firstly want to get out there that food is an addiction. I’m always going to have that mindset. I struggled with it,” she said.
”The way I was treated…you never want to go back there. You should never judge a book by it’s cover. Everybody has a story, everybody has roots that they have to get to.
“For those people [who think it’s gross with people on the show], they are just ignorant,” she added. ”You can overcome your struggles and fears, you can do what I did.”
Today, through her Facebook page, Marla shares snapshots of her new life with her family—something that once felt out of reach.
Her journey remains one of the most powerful transformations ever seen on My 600-lb Life, proving that even in the darkest circumstances, change is possible.
