To cope with his personal pain -- his parent's divorce and the death of his father -- John says he used food as his medicine and this caused him to gain a significant amount of weight. He says his low point was his doctor sent him to a fish market because the doctor did not have a scale that would accommodate John. At this point, he weighed 540 pounds and he was told he could die at young age.

After many unsuccessful attempts to lose weight on a variety of diets, he started a boot camp and began to dramatically lose weight.

After losing over 300 pounds, John joins The Doctors to show off his amazing transformation. He tells us that he has lost 297 pounds in just the last 15 months and he says he did with "eating right and exercising."

"I've learned so much through this journey... for me, the key was finding a community of people who are like-minded, who have goals to lose weight and eat better and be healthier, so that you're not doing it alone... [it was] the most effective form of accountability I can imagine," he says when asked about what he learned during the course of his weight loss journey.

John's wife Caila says of her husband's accomplishments, "He's amazing. He's put in a lot of hard work and discipline. He's endured a lot of challenges and failures but he just kept trying... and he finally found his success story."

Now that John has lost so much weight, he is left with a large amount of excess skin, and plastic surgeon Dr. Michael Zarrabi and plastic surgeon Dr. Daniel Barrett have offered him skin reduction surgery at no cost to him.

After the surprise, John tells The Doctors, "The thing I have always wanted the most is just to be able to function and move and look like a normal person and put on clothes like a normal person... and to be able to maybe experience things like normal person in every sense is a blessing."
