How long can a Leopard Gecko go without food?

A leopard gecko can go two weeks without food, but it is best to feed him/her ten crickets (or more) a week. I find it handy to put about twenty crickets or less in the cage with my leopard gecko at a time, as long as you keep an apple (or potato) slice for the crickets in the container and let him eat at his own pace. My gecko actually eats twenty crickets a week, but I don't think this amount is necessary because he has gotten a very fat tail (that is where they store extra fat). I've never tried pinkies or mealworms before, but I'm sure this method would work the same, but put the food they eat in the container and you don't need to feed quite as much to your leopard gecko.
