The story of Nathan for You is fictional. It's designed to be humorous and engaging, not based on real events or people. The characters and situations are made up to entertain the audience.
I don't really know who Nathan Bartlett is in this context. He could be an ordinary person whose story is being told, or perhaps he's someone with a unique or remarkable story.
The 'Funeral Home' segment was quite something. Nathan Fielder proposed to a funeral home that they offer a new service, a 'reverse - mortuary' where people could come and practice being dead. It was a completely absurd idea. He set up a fake marketing campaign for it, with brochures and testimonials. He even had people come in to test out the experience. It was all a big joke, but he played it so straight - faced that the funeral home owners and the public were both caught up in this strange fake story. He used the shock value of the idea to draw attention to the funeral home in a very different way.

In Nathan's story, there were multiple challenges. Physically, his weight put a massive strain on his body, leading to potential organ problems and limited mobility. Emotionally, he may have faced self - esteem issues and perhaps depression due to his weight. Socially, he might have been isolated as his size made it difficult to participate in normal social activities. And when it came to his weight loss journey, following the strict diet and exercise regime prescribed by the doctor would have been extremely difficult. There could have been moments of self - doubt and the temptation to go back to his old eating habits, all of which were significant challenges he had to overcome.
In the story, one special thing could be its taste. The combination of the juicy hot dog, the soft bun, and the classic toppings like mustard and onions makes it unique.
