I thought about not replying to your post, but I decided it needs a reply.
I have a degree in Physiology and Pharmacology and fly five long days a week in a Muslim country.
I think that kind of qualifies me to make a comment on the subject!
My own opinion is that fasting, as far as food is concerned, is not a problem - it is the abstinence from everything 'by mouth' that can be a problem - and in particular, abstinence from drinking between sunrise and sunset. Feeling hungry is not a danger!
