This is not because of one single account, but after hearing story after story of a "fast gone bad," I no longer agree with fasting.
Firstly, some conditions WORSEN!! That's right, they don't just not go away, but they get bad.
Secondly I believe that the mindset you have to be in, in order to fast is kind of nuts - what animal would knowingly not eat unless they actually couldn't.
Recently I had a fever and felt nauseated (my immunity is low due to a staph infection and possible flu) and I didn't want to eat for about 24 hours. So I didn't. But when I wanted to eat again...I ate!!
Just because fasting has cured an ailment, doesn't make it safe. Any eliminative practice will "cure" things caused by toxins in the diet because it eliminates them. And fasting definitely eliminates all of 'em.
Lastly, I have now heard of way way way too many deaths related to fasting for it to merit doing, except perhaps in rare cases or in a medical facility with all the equipment available if something did happen.
I agree with Harley when he discourages fasting and fully support his strong views in this regard.
