Ramadan is a month of fasting, where no food or water is consumed whilst the sun is up. Children, elderly, pregnant women and the ill are all exempt. Plus there's some interesting rules if you're in an unusual geographical position (in the ISS or North pole, so the sun never goes down). Dietary wise it's closest to intermittent fasting, as you normally wont eat for 8-14 hours of the day, then have a big dinner. I had a bodybuilder friend who used it as an enforced time to cut weight.
