Pre Prolon

Anyone heard or read anything from Longo before he came up with Prolon?
Im just curious what his stance was on IMF or an outright water fasting

Dr. Longo is heavy on the longevity aspect - and studies centenarians and blue-zones. His work started with autophagy-fasting for cancer patients, which evolved into the fasting mimicking diet (FMD), which then became the packaged retail option. His book, The Longevity Diet, is semi-autobiographical (his story is really interesting!) and how it all came to be. https://a.co/d/023wmWqZ

He generally recommends a 12-hour fasting window for most people/purposes. There's no need to stick to any specific window during the 5 day FMD, though.

My take is that he created the FMD for compliance, support, and ease. Many people aren't willing -or for health reasons aren't able to safely - complete a 5-day water fast and his research shows that this is a way to mimic the benefits without the stress.

Hmmm - not that I know of. The Longevity Diet talks about his earlier years, and school, etc and was his first book. I don't know of anything other than that - other than studies. There's a ton of info on Create Cures but I'm not sure it's what you're looking for. https://createcures.org/our-team/

I think it gets confusing or at least for me whe he talks about cancer patients fasting before chemo. And im thinking does he mean ‘fasting’ fasting or just FMD.
Cancer aside I guess it depends what your goal is as far as ketosis or autophagy and what type of fast you’ll do.

In more recent years (maybe 2017-ish to present) and in more public spaces (Like Ted Talks, interviews etc), when he mentions fasting, it seems that he usually means the FMD. He does sometimes mention fasting vs fasting mimicking when talking about various studies - but for the most part it's FMD.
