A sugar gliders diet consists of a staple food and fresh fruits and vegies. It's about 30% of their staple diet and about 70% of fresh foods. There are different staple diets you can choose but the two most popular are the BML and the HPW.'you can google them and find the recipes and make them exactly. I feed mine every night around 9ish. I feed the exotic nutrition instant HPW. It works well for me. I feed strawberries, blueberries, grapes, spinach, bell pepper, boiled chicken, boiled turkey, raspberries, blackberries, mangos and a few others. You can also leave sugar glider pellets in their cage during the day incase they wake up and want a snack. I use the vita smart sugar glider pellets because that is what my breeder used, but I'm planning on switching to the exotic nutrition glider complete.
I hope this helped clear some thigns up. Gliders diet is the hardest part of having them.
