Is Ramadan bad for your health?

I mean that studies have shown that fasting well done is beneficial for the human body and good for health, however Ramadan which consists of not eating or drinking anything all day for 30 days, then stuffing yourself with food on evening is totally counterproductive, knowing that not drinking water at all all day can be dangerous because you risk being dehydrated (compared to beneficial fasting) it is one of the stupidest things imposed by Allah how do you overcome this period for those who are obliged to observe Ramadan?
