Tjones covered most of it so I won't repeat all that
Diet, us telling you what we feed isn't the best way to chose a diet for YOU. I have my own reasons for feeding the diet I chose as does everyone else. I actually prefer to not tell people what I feed so it doesn't sway their decision one way or the other.
Personally, there are 2 diets I suggest and endorse out of the many widely used diets. Bml and Critter Love, because they have both been used for 10 yrs or longer and have undergone testing.
So what should you consider? ...
1 Are you ok with powdered ingredients and buying things online?
IF yes, Critter love, which has powdered ingredients and you have to order through Critter Love.

IF NO, Bml. This applies to all well known diets and bml, bml is the only diet widely used that you can find all the ingredients locally and not have to order online. Everything in the recipe can be found at grocery stores and pet stores. The only powdered ingredients are the calcium and vitamins.

Those 2 question can narrow it down for a lot of diets not just Bml and Critter love.
The other bonus to these two diets are both of the creators are active in the online community and make themselves available to answer questions, and help people struggling with their diet. Peggy created Critter Love

2, what can you afford to feed consistently ? Doesn't seem like a big issue especially when you only have 1 or 2 gliders but it can be. I have 9, so cost is part of why I chose the diet I did. I now order supplies in bulk online to make it even more cost effective, but in a pinch I can still buy everything locally.
3, Prep and freezer space... Some diets require a lot of chopping and take up a lot of room in the freezer. I physically can't stand n chop food for hours and my freezer space is about the size of a cooler that holds 6 packs
ok it's a little bigger than that but not by much. I don't have space for a gallon of salad and a gallon of staple.
Ultimately, the gliders also have to eat it...which may trump all of our personal reasons for choosing a diet.
So in the end I did pretty much tell you which diet I chose and why without actually saying it
Can you figure it out??
