James "L.B." Bonner spent most of his life overweight, but it didn't hold him back-until he wasn't able to play football and then lost his leg in an accident in 2013 when he was 25 years old. That's when his health started to spiral out of control. He sought comfort in food and alcohol, which led to his weight ballooning to nearly 650 pounds. At that point, L.B. contacted renowned bariatric surgeon Dr. Younan Nowzaradan, which led to his appearance on an episode of My 600-Lb. Life. On the show, viewers saw LB struggle with obesity following a tragic accident that claimed his right leg. Even though he once weighed 650 pounds, LB's hard work and dedication helped get him in the 200-pound range. His spirit and determination as displayed through his story, quickly made LB a fan-favorite. Show less «
