Depending on what Ramadan really means to you, you could still eat normally while following the rules (if youre crazy enough, just reverse your sleep pattern, or wake up during the night for a middle of the night meal). If you are really intent on observing it for its real purpose, it really won't hurt you much to only eat two meals a day, as long as you can keep your hunger in check and not blow your calorie balance. One month of two meals a day (one right before you sleep and another as soon as you wake up) really shouldn't set you back as long as you try to split the calories up between the meals and make sure you aren't over (or under) doing it calorie wise. Now, should you decide to do it for three months straight... no guarentees on that one that's for sure.
If I remember right, part of the point of Ramadan is the fasting as a form of self-sacrifice or something? Pardon my ignorance if I am incorrect, but it seems like in order to properly observe this event, you are required to put your own health at risk. As if that is specifically the point... so i guess trying to find ways around it is quite contradictory to the reason for doing it in the first place...?
well, to each their own as the saying goes. We do what we do because it is what we "know", and as such, I wish you the best of luck in getting through this period in a manner that most meets your physical and spiritual beliefs.
