Well, there are lots of types of fasting. Juice or water or nothing. Skipping a meal, or not eating solid foods for 3 months. IMO not eating during the day but then eating a lot at night might not be the best type of fast.

But even so, it would be interesting to see numbers anyway.

Ramadan is not really fasting these days. Most people do feasts every day (or something close to every day) on Ramadan when the sun goes down.
