Some of you may have noticed that it is the Islamic holy month of Ramadan. My stomach has. I can hear it groaning as I type this post. I won't be eating anything till 8.38pm.
I've been fasting since I was about 12 or 13, and every year I'm asked the same bunch of questions about Ramadan by well-meaning non-Muslim friends and colleagues. So I thought I'd use this blog post to answer some of these common queries.
Here we go:
What is Ramadan ?
It's the ninth month of the Islamic calendar, when Muslims all over the world spend 30 days observing the fast. Muslims believe it is a blessed month; it is the month in which we believe the Quran was first revealed to the Prophet Muhammad.
So you don't eat for 30 days? Is that physically possible?
Sorry, what? There seems to be some confusion about the timing of the fast. The fast takes place from sunrise to sunset each day, for 30 days, that is to say, during daylight hours only. We don't actually fast for 30 whole days in a row -- that would be impossible, if not worthy of a permanent place in the Guinness Book of Records.
You can drink water, right?
Nope. No water, no juice, no milk, no liquids whatsoever. In fact, the list of "prohibited" items and activities in Ramadan is fairly comprehensive: no food, no drink, no smoking, no drugs, no sex, no bad language or bad behaviour whatsoever, from sunrise to sunset each day. That's the challenge.
But doesn't that damange your health?
Hmm. I haven't noticed my fellow Muslims dropping like flies around me, as we fast together each year. Millions upon millions of Muslims, in fact, have been fasting for centuries without falling sick, toppling over or suffering from premature death. Fasting, contrary to popular opinion, doesn't damage your health. Vulnerable individuals – the sick, the elderly, children, pregnant women – are exempt from the requirement to fast. And then there is the range of academic studies  which show several health benefits arising from Ramadan-type fasting, "such as lower LDL cholesterol, loss of excessive fatty tissue or reduced anxiety in the fasting subjects".
So do you end up losing weight at the end of it?
I can't speak for others, but I always end up putting on weight because I eat so much every night, at iftar  time, to compensate for not having eaten all day! From my own experience, few Muslims treat Ramadan as a period of dieting, or use the fast to lose weight.
Why is Ramadan in the summer this year? Didn't it used to be in winter?
Since 622AD, and the time of the Prophet Muhammad, Islam has operated on a lunar calendar , with months beginning when the first crescent of a new moon is sighted. As the Islamic lunar calendar year is 11 to 12 days shorter than the solar year and contains no leap days, etc, the date of Ramadan moves back through our calendar each year. (For example, a few years ago, Ramadan coincided with our winter; the days were shorter and the fasts were easier!)
What is the point of starving yourself for 30 days?
Ramadan is a deeply spiritual time for Muslims. By fasting, we cut ourselves off from the distractions and temptations of our busy, hectic, materialistic lives and try to gain closeness to God. The Quran describes the main purpose of the fast as being to "attain taqwa", or "God-consciousness". We use the fast to try to purify and cleanse our souls, and to ask forgivness for our sins. We also learn self-restraint and we become much more aware of those less fortunate people around us for whom "fasting" is not a choice, for whom hunger is part of daily life. The fast is an act of worship and a spiritual act; it is also an act of social solidarity.
