Extended periods of water-only fasting (e.g., 7 days per quarter, 3 days per month) may not provide longevity benefits and can lead to profound misery and potential muscle mass loss.

“even if you went with something longer like what I used to do right I used to do seven days of water only per quarter three days per month so I was but I was basically always like it would be three day fast three day fast seven day fast just imagine doing that all year rotating rotating routing for many years I did that now I certainly believed and to this day I have no idea if that provided a benefit but my thesis was the downside of this is relatively circumscribed which is profound misery for a few days and what I didn't appreciate the time which I obviously now look back at and realize is muscle mass”
