Turtle wont eat

Question
I have an Asian box turtle. I know they don't normally eat in the Winter ,but he doesn't
like to eat during the Summer either. He used to enjoy dried meal worms, mandarin oranges,
live worms, and grapes. Now all he does is drink a lot of water. Thank you for your help.

Answer
Not really sure how to answer the question.  How old is the turtle?  How long has it been since it stopped eating or stopping eating as much?  Has there been any change in environment?  Without knowing any of those answers I would say try other foods as juveniles and babies they eat more meat as they mature they tend to eat more plant material.  Try feeding in the early morning.  Also maybe just raise the temp a bit to stimulate the metabolism.  Depending on where you live if it's warm outside you could also put the turtle outside for a bit in the sun that will often stimulate them to eat more as well.
