Unfortunately this video really misses the point of why and how people fast. There's absolutely no information leading up to the fast about what they ate to prepare and how they exercised, no details about there genetic make up and basically a travel show with a bit of chit chat.
As this is the sort of film that people will search out rather than stumble across due to the niche subject matter, you really need to provide more scientific evidence and show supporting historic facts about fasting, such as the history of it and where it originated. As I'm interested in fasting I expected a lot more fasting back story.
At times these just feels like a couple of bro's who are interested in themselves and that's it. Which is a shame. Seems like there's still a gap in the market to fill if someone wants to make a real film about fasting, unfortunately this isn't it.
