I remember Muslim students in my high school getting a special pass to go to the library instead of the cafeteria during Ramadan- being around all of that food would be torture. I'm sure it's much harder in a western country!
I'm Jewish, and we observe a 24 hour fast on Yom Kippur, and it is definitely not fun- I can't imagine a month of fasts (albeit shorter ones)! Judaism also has an important clause called Pikuach Nefesh, where preservation of human life is paramount to any religious consideration- so if you are diabetic, elderly, etc. you are not supposed to fast. Of course, there are those that do so anyway- I've seen ambulances come to more than one break-fast and temple service. Even if you are perfectly healthy and fasting for any reason, please take care of yourself!!
And a happy and healthy Ramadan to all who observe it
