I used to be a pretty big kid in grade school and middle school (34" waist in 7th grade) and I had to deal with a lot of the same crap that this story talks about, though probably to a lesser degree. And in 9th grade I had enough and dropped from nearly 180 lbs to 115, which was too small in retrospect.
This story really struck a cord with me as it's a similar story, but his is so much more triumphant and I just wanted to give this man a hand shake because he deserves it. From descending into a personal hell and being able to find a way out, to me it's a story that says "it's never too late." Thought some others here might appreciate reading it.
