My 600-lb Life Season 13, Episode 1 was the first time that people saw Jonathan Matthew Colp’s amazing transformation story. Many people could relate to his story because of how emotional and determined it was. Jonathan often didn’t have enough food because he grew up in a family where money was tight. His mother always made sure he ate well when food was around, which made him start to eat too much at a young age. Jonathan had to deal with bullying and emotional problems as he grew up, especially when his brother moved in with their grandmother. During those difficult times, he felt the urge to eat in order to feel better.
Jonathan tried to lose weight as an adult, but he had a big setback when he lost both of his parents in a short amount of time. The stress made him go back to bad habits. But when he got a harsh wake-up call about his health, he decided to see famous bariatric surgeon Dr. Nowzaradan. That was the start of his amazing journey to get better.
We at Spiky TV closely monitored Jonathan’s journey, and now we aim to provide you with comprehensive information about his current status.
Jonathan Colp’s Weight Loss Journey: A Story of Persistence
Jonathan weighed an incredible 641.5 pounds when he started his weight loss journey. Dr. Now made it very clear: to be eligible for weight loss surgery, you need to lose 80 pounds in two months. The doctor put him on a strict daily diet of 1,200 calories and told him to exercise regularly. Jonathan’s weight had dropped to 554.1 pounds in three months, which was enough to get him approved for surgery, but only if he met certain conditions. He needed to relocate to Houston, Texas, so that Dr. Now and his team could closely monitor his progress.
Jonathan took the requirement seriously. By the seventh month of his program, he had settled in Houston and continued to make steady progress. At that time, his weight was 516.5 pounds. Dr. Nowzaradan scheduled the surgery, instructing him to shed another 30 pounds beforehand. By the time surgery day arrived, Jonathan weighed in at 489 pounds—just a few pounds shy of the goal. Yet, thanks to his visible dedication and commitment, the doctor decided to move forward with the operation.
After the procedure, Jonathan was expected to lose another 25 pounds in the first month, with more progress anticipated in the months that followed. And he didn’t disappoint. By the end of the one-year journey, Jonathan had slimmed down to an impressive 425 pounds—losing over 216 pounds in total. He also regained much of his mobility, which allowed him to live more independently and leave the house more often.
Jonathan’s Return to Work as an EMT: Giving Back Through Service
Long before his health deteriorated, Jonathan was passionate about helping others. He had played baseball during school and even joined the football team despite struggling with weight in his early teen years. Sadly, the bullying got too much for him, and his mother decided to homeschool him.
Jonathan eventually went to college and attended both John A. Logan College and Rend Lake College. He worked part-time to pay for his education. He eventually became a certified Emergency Medical Technician (EMT) and worked for the Williamson County Ambulance Service. Later, he joined Continental EMS. But as he gained weight, it became harder for him to do the physical tasks that emergency services needed him to do.
As a result, he started doing jobs that weren’t as hard on his body. He started out working at a petrol station and worked his way up to store manager. Later, when his weight made it hard for him to move around, he got a job at a call centre. At this time, his wife was the only one who made money for the family.
Because of the progress made during and after the show, Jonathan was finally able to go back to the pitch he loved. He went back to work as an EMT at Franklin Hospital in February 2024, showing that his hard work had paid off and that he was ready to get his career back on track.
Social Media Presence: Inspiring Others Online
Jonathan has made a name for himself online in addition to his personal and professional achievements. He has more than 4,000 followers on Facebook, and his timeline is full of motivation, jokes, and updates on his life. He often posts pictures of his progress, motivational quotes, and health tips about diet and exercise. His social media posts show that he is a fun-loving person who cares about his long-term health.
He also talks about important events in his life with his wife, Tzena, who has been a big part of his change. He wrote about going to the gym with her in July 2025 and how discipline and support from each other can help couples reach their goals together.
Many of his followers see him as an inspiration and leave encouraging and praising comments on his posts. Jonathan’s online updates remind many people that change is possible if you work hard, stay committed, and have a strong support system.
A Supportive Love Story: Jonathan and His Wife, Tzena
Jonathan often says that one of his biggest blessings is his wife, Tzena. The couple met when he was working as an EMT and she was a nurse. Their bond grew stronger over time, and they eventually married after two years of dating. From day one, she stood by him—not just emotionally, but physically too. She ate the same foods, worked out with him, and followed his daily schedule to make sure they both stayed on track.
Jonathan often discussed how much her support meant to him during the show and even after it. They always wanted to have a healthy, active life together, and now they are living it. They walk, go to the gym and even go to the beach—things that seemed impossible when Jonathan couldn’t move around much.
Many people admire how well they work together as part of Jonathan’s transformation story.
A Heartfelt Loss and Moving Forward
People also know that Jonathan and Tzena love animals. They loved their two dogs—Bullet and Jackie O—like they were their own kids. Sadly, in late July 2025, they lost one of their beloved dogs, which had a big impact on them. Jonathan used social media to tell people about the news and remember the pet. He wrote about how the dog had a full life full of love and care, and he said that her personality was “almost human“.
He said he was sad but also thankful for the time they had with her. Many of his followers connected with his message, which showed how deep his feelings were and how well he could handle difficult times.
At Spiky TV, we keep celebrating success stories like Jonathan’s because they show that change is possible no matter where you start.
