Many of us are not huge fans of the GI scale and feel that a combo of GI plus GL plus lifestyle is how food choices should be made.
Given that, for a cut, I suggest: Apples, Peaches, Pears, Berries, Lemons, Limes and Grapefruit. Of course that's how strict you are cutting. If you just want to lose a few pounds then don't limit yourself to a select few because in the grand scheme of things, fruit is very healthy. If you are on a really strict cut, then just eat those that I suggested.
For bulking, eat any fruit you want.
