There have been some studies, but I dont have the references at hand. Fasting can regenerate the entire immune system for one, it can also assist in accelerated tissue repair. Anecdotally I can tell you I've been far more productive today than most days because I'm being more conservative with how I expend my energy therefore didnt waste time on things like reddit and FB, and because my body isnt busy both worrying about my next meal or digesting it, I've had much greater clarity of thought which has been great for focus.

Edit: sp and grammar

I imagine that these impacts are varied. For people of poor health with a diet of meager nutrition, or for diabetics with irregular blood sugar levels, Ramadan fasting may lead to worse health outcomes. For people who are not diabetic but at risk of becoming so, Ramadan fasting may lead to better health outcomes. Just a guess.

Those with severe health issues are not obligated to fast. Those that do have health issues but are still able to fast notice an improvement in health if they fast in the recommended way. If they continue with their poor diet at the prescribed eating times then nothing changes.

There's nothing but muslims' so called studies on health benefits of islamic fasting. Islamic fasting may be anything but healthy. It goes like this: wake up in the middle of the night. Eat yourself full and maybe more. Sleep. Wake up. Don't eat or drink anything until the sun goes down. Eat yourself full and maybe more. Sleep until the next cycle begins. Putting on more unhealthy weight during and after ramadan is not rare.

Drinking water is forbidden until the sun comes down and the fasting is over for the day, and in summer, excessive dehydration is fatal.
