The game automatically feeds your entire village from the bin periodically - you would have to prevent the entire village from collecting food while the food in the bin runs out.

With 118,000 food, it would be much easier to simply change the game to 2x speed and wait a day -- if you don't have any villagers with breeding as their preferred, you shouldn't gain any population while you are away (if they breed while you aren't looking, you might miss the babies and be stuck in the same position again).
