The "research" is politically motivated, it is thus garbage. Especially considering that it would be dangerous to publish the result if it were to show the other way, not that they would want to publish it.

Besides, not having even a drop of water for longer than 12 hours during summer is dangerous, not only to fasting people themselves but to the society as a whole since they drive cars and they have higher rate of fainting during that. But doing those for the name of religion is somehow acceptable in our society..
