When there is something good to be had there is always going to be someone, professional or not, that will be working hard to see that others don't benefit from it.
Thanks for doing all that diligent research to find exactly that stuff and presenting it here in the support forum for water fasting.
Based on the fact that you would take all that time to dig up the trash and present it here as if there is some concern, puts you squarely in the category of those who would prefer others do not benefit from something good.
You have carefully prefaced everything, - that you don't want a debate, its not your information, you only want opinions, you don't want to go against the terms of service, all spells the fact that you are working hard like the others.
Just google Master Cleanse and you will find plenty of negative material written on that cleanse. All presented by the people that don't want others to benefit from something good. All nicely documented by professionals from this or that field.
Doesn't matter how many doctors degrees they have behind them when they present this stuff, they're still in the same category as you.
Presenting yourself as a concerned good guy and carefully bringing it here in hope that plenty of people will be duped by your concerns.
Fortunately there are plenty of knowledgeable people here that can easily see through your intentions, its just hard pinning you down with the manner in which you have skillfully set this up, presented it, and are responding to others.
