It's also important to note that the nutritional values of your feeders can vary quite a bit with gutload content. Unfortunately a lot of extensive research has not been done, either in feeder nutrition or gecko nutrition, and all studies must be taken with a grain of salt.
I also would highly recommend variety in however you choose to feed. My cresties get fruit as an occasional treat, not a staple, so absolute values from one study are less important.
Staple diet, in my collection, is well-gutloaded bugs (crickets and roaches; larvae are typically high in fat), with at least two MRP style diets mixed, on the idea that no one diet is likely to be correct.
Occasional treats such as phoenix worms, horn worms, silk worms, and raw minced fruit are appreciated by the geckos, but remember that these are only treats, and should be used sparingly.
