To be honest I am suspicious of fasting for health purposes, for example during Ramadan this is me : - I can only sleep for a maximum of 4 hours each night - During my waking hours I extremely energetic and focused - I never nap, can't physically do it - I lose my appetite when I break my fast, I have to force myself to eat a reasonable amount, about 1 meal and water - I lose alot of weight real fast, which I suspect includes some muscle mass My father is the same, but not the rest of my family. I would not continue this fast outside of Ramadan for too long for a few reasons : - Sleeping 4hrs a night does not seem healthy, although I feel fine I don't want to play games with my health - I don't recommend fasting with no water, I don't know if this has any real health benefits. Of course this is an anecdote, and not scientific in anyway, but my feeling is that genetics and psychology influence the resulting effects of a fast on a person.
