Why fasting during ramadan

But if you're careful, you can avoid putting on weight, and you may actually lose a few pounds. One meta-analysis of scientific studies on the effects of Ramadan fasting on body weight found that "[w]eight changes during Ramadan were relatively small and mostly reversed after Ramadan, gradually returning to pre-Ramadan status. Ramadan provides an opportunity to lose weight, but structured and consistent lifestyle modifications are necessary to achieve lasting weight loss.

So just like with any other extreme diet plan, you may lose a few pounds, but unless you actually make "structured and consistent lifestyle modifications," you're probably not going to see major, lasting results. For religious matters, Muslims follow a lunar calendar — that is, one based on the phases of the moon — whose 12 months add up to approximately days.

That's 11 days shorter than the days of the standard Gregorian calendar. Therefore, the Islamic lunar calendar moves backward approximately 11 days each year in relation to the regular Gregorian calendar. So that means that the first day of the month of Ramadan, which is the ninth month of the Islamic lunar calendar, moves backward by about 11 days each year.

This has a large impact on how people experience Ramadan from year to year. When Ramadan falls in the winter, it's much easier to fast: the days are shorter, which means you don't have to fast as long, and it's colder out, so not being able to drink water all day isn't as big of a deal because you're not sweating as much.

Conversely, when Ramadan falls in the summer, fasting can be brutal. In many Muslim countries in the Middle East and Africa, summer temperatures can reach levels usually reserved for the deepest bowels of hell.

And in some Northern European countries such as Iceland, Norway, and Sweden where, yes, there are Muslims , fasting can last an average of 20 hours or more in the summer. And in a few places above the Arctic Circle, the sun never actually sets in the summer. In these cases, Muslim religious authorities have decreed that Muslims can either fast along with the closest Muslim country or fast along with Mecca, Saudi Arabia. There's a reason "Ramadan start date" is one of the most-searched phrases every single year.

That's because Muslims around the world do not know when exactly Ramadan is actually supposed to start.

If you Google it, you'll see there's a little disclaimer under Google's answer that says "Dates may vary":. That also has to do with the moon — as well as disagreements about science, history, and tradition, plus a bit of geopolitical rivalry.

The beginning of each new month in the Islamic calendar starts on the new moon. Which means the month of Ramadan starts on the new moon. Simple enough, right? If it's been a while since your high school astronomy class, here's a reminder of what the phases of the moon look like:.

Back in Mohammed's day, in sixth-century Arabia, astronomical calculations weren't as precise as they are today, so people went by what they could see with the naked eye. Since the new moon isn't actually super visible in the night sky as you can see above , Muslims traditionally waited to start fasting until the small sliver of crescent moon became visible.

There's even a saying attributed to the Prophet Mohammed about waiting to start the fast until you see the crescent. Some people think this is why the star and crescent is the symbol of Islam, but the crescent was used as a symbol long before Islam.

This method was a bit messy, though, since things like clouds or just the difficulty of spotting the moon in some locations often led to different groups starting their fast on separate days, even within the same country. Each community, village, or even mosque within the village might send its own guy out to look for the crescent, with rival groups arguing over whether the other guy really saw it.

Today, however, we have precise scientific calculations that tell us exactly when the new moon begins, and we don't need to wait until someone spots a tiny crescent in the sky. In fact, according to the Oxford Dictionary of Islam , "The need to determine the precise appearance of the hilal [crescent moon] was one of the inducements for Muslim scholars to study astronomy. So, problem solved! Except that some Muslim scholars believe we should still wait until the slight crescent moon is visible in the night sky because that's what Mohammed said to do and that's the way we've always done it.

Others argue that Islam has a strong tradition of reason, knowledge, and science, and that if Mohammed were around today, he'd choose the more precise scientific calculations over sending the guy at the mosque with the best eyesight outside to squint at the night sky.

To make things even more fun, some argue that the whole world should just follow the official moon-sighting decrees of Saudi Arabia, the birthplace of Islam and the location of its holiest sites. But not everyone thinks that's such a swell idea — especially rival countries like Pakistan and Iran, which balk at the idea of treating Saudi Arabia as the ultimate authority on anything having to do with Islam.

All this means that each year, Muslims around the world get to experience the delightful lunacy of "moon-sighting fighting. For the most part, no. Both Sunni and Shia Muslims fast during Ramadan. But there are some minor differences — for instance, Sunnis break their daily fast at sunset , when the sun is no longer visible on the horizon but there's still light in the sky , whereas Shia wait until the redness of the setting sun has completely vanished and the sky is totally dark.

Shia also celebrate an additional holiday within the month of Ramadan that Sunnis do not. For three days — the 19th, 20th, and 21st days of Ramadan — Shia commemorate the martyrdom of Ali ibn Abi Talib, the cousin and son-in-law of the Prophet Mohammed who was both the revered fourth caliph of Sunni Islam and the first "legitimate" imam leader of Shia Islam.

Ali was assassinated in the fierce civil wars that erupted following the death of Mohammed over who should lead the Muslim community in his stead.

On the 19th day of the month of Ramadan, while Ali was worshipping at a mosque in Kufa, Iraq, an assassin from a group of rebels who opposed his leadership fatally struck him with a poisoned sword.

Ali died two days later. Through this section, we provide research-based health information, and all that is happening in Aster Hospital. Blogs Health and fitness tips by expert doctors.
