what you do is you make a huge batch of a recipe for a "glider nectar"that contains all their needed supplements and calcium. you freeze the batch in icecube trays and then pop them out and put them into a huge freezer bag then at night, you can just take the needed amount of cubes out and offer fruits and veggies on the side.
each diet will have different requirements for what you feed along side the nectar. for an example, LGRS Suggie soup has you feed which ever combination of fruits and veggies on the side, but has you also feed an additional source of protein like boiled chicken, eggs or turkey. BML however has you feed a limited list of fruits and veggies to balance out the high calcium ratio of the overall finished nectar. but, it calls for all the protein gliders need in the recipe so you don't have to feed protein on the side like LGRS. other diets like GOHPW, Gliderkids and OHPW allows you to feed whatever combination of fruits and veggies nightly with no additional protein because it calls for all the needed protein in the recipe for the nectar, and the overall ratio of the nectar is 2:1 or very close.
I hope this has helped clear some things up:)
