Donald Shelton
It was quite heartbreaking to hear Donald Shelton admit that he would be totally helpless if it had not been for his parents. At a weight of 678 pounds, he could barely walk. He lost 300 pounds after getting gastric bypass surgery, but this was not the end of his worries just yet. After a bad fall, he was taken to the hospital and went into a coma. Doctors learned that he was suffering from Guillain-Barre syndrome! It led to the fluctuation of his weight, but he has since kept his eyes on the prize and stayed fit.
Chuck Turner
We learned that Chuck Turner weighed almost 700 pounds when he joined the show for its second season. His wife looked after not only their son but also him. She later admitted that it sometimes felt like she was his servant, which motivated him to change his lifestyle. He shared that the murder of his first wife had been the reason for his weight gain. He received physical and emotional help, which pushed him to drop almost two-thirds of his weight! He now weighs around 260 pounds. Nice.
