I don't question that the show host has good intentions but she comes off as insincere.
What's not being told here is the emotional pain (combined with bad dietary habits) that got Nick (the teenager) to where he was. The show is celebrating his 60 lb. weight loss, but ignoring the underlying cause. The darker feelings that arose post-operation weren't caused by the operation. It was the quiet time spent healing that allowed long buried feelings to surface.
I'm saying this is being told through a (relatively) skinny person's eyes because it doesn't focus on what smaller size people have in common with larger size people. Instead, it chooses to focus on his extreme body statistics, the foreignness of fresh vegetables in the family's home and the hackneyed "I can fit into one pant leg of my old pants" ... more the aspects of a freak show.
If this story were told with true compassion it would skip over all of the above and we would see the world through NIck's eyes. We would see the primitive instinct of humanity to diminish the momentum of those perceived as different and how that feeds into a negative cycle for Nick. Being the class clown may gain him friends but it comes at the cost of people understanding that he has a full range of human emotion and human wants just like everybody else. And it comes at the cost to Nick of realizing his value to other people arises from something more than being funny.
Nick, my heart goes out to you on your journey.
