Little worried

My leopard gecko hasn't eaten for about five days,he hasn't lost any weight or body mass, and he pooped about two days into this fast of his.I have had for about two months now and he has been eating really well and he just shed yesterday.He is a 5 year old male, could this be because of the breeding season? Just want to make sure he is okay.

If he just shed that is probably your answer. Did he eat the shed? Mine usually don't eat right before a shed and don't eat right after either.
Give it a day or so, I'm sure he'll be fine.
What is his set up though? Temps and substrate, hides etc. You probably posted it somewhere... :)
