The Muslims have a similar fast and during Ramadan just before dinner, everyone rushes to the grocery stores hoarding every food on the shelves! They don't seem to lose weight on the 30-day fast so I suppose they make it all up from 6pm to 12am. Although Ramadan gives you 6 hours to eat, allowing some workout sessions within that time as well. However, I doubt hard workout sessions would be possible.
