This man didn't deliberately take his 'before' picture - someone else did. When he saw it, it became the spark that ignited his desire to change his life. He always knew that he was badly overweight, but had no idea he looked quite as bad as he did. When he got on the scales, he was amazed to find that he'd ballooned to 330 pounds. His eating and drinking had got out of control, but now he was determined to take that control back.
The day after he saw the picture, he cut out all of the bread and sugar from his diet, and bought himself a gym membership. He still allows himself the occasional beer, but taken in moderation alongside a healthy diet there's no reason why he shouldn't. When he got down to 220 pounds, he asked the person who took the first picture to photograph him again in the same chair. This time, he was much happier with what he saw.
