Lots of people running on beaches like a sanitary towel commercial, meandering, chatting about random medical health numbers, personal ancedotes and 2nd hand anecdotes, drone shots, random yoga 'how this worked for me - miracle' 'my hob-o-diba-doblin is down from 300 to 25'. (I made that last bit up).

This film really does little to push forward the science of fasting - all that is being said is a similar thing some of the recent vegan documentaries are saying. Like the makers just watched 'What the Health' and decided to put out a fasting version.

There is a lot to fasting, as there is to plant based diets. Essentially you are eating less and eating better quality foods- cutting out the terrible junk processed food. What is the difference in effect to a plant based diet? What different types of fasting are there? Fast Mimicking? Water fasting? Fruit fasting? Intermittent fasting? How long for? Hours? Days? Weeks? What are the dangers of each one? Do you need medical supervision? Which could be done safely on your own? And for whom? That could have been covered in much more detail, they have an interview Dr Valter Longo, an expert who could shed real insight but he needed more screen time. Like the makers left out the hard bits that might confuse the intellectually weak in the audience or not get sued - fasting is great, but don't do it as it couldbe dangerous for some people.

I think this documentary could be re-edited, and actually be much better. An opportunity missed.

An interesting topic with a lousy execution. There were too many head cases and weirdos in this for me to take it seriously, from pukey-anorexic girl, to muscle-OCD-put a shirt on-boy, to the Jesus freaks. Just the facts, ma'am.

The woman with the headaches had a good story.

I was expecting to see Dr. Nick Riviera from The Simpsons give his take on the subject. They tried to cover too much territory in this to be clear and accurate.

You don't need a stupid movie to show you how to fast its free, i do amazing fasting around 16-18h per day sometimes go 24h and back to normal, i do terrible pass the 30h mark you just don't need to go there.

Fasting does great for the sweet tooth, sugar craving, shrink the stomach eat less, etc, combined with exercise and cardio.
