While bananas may be a wonderful source of potassium, they have a GI of 77 which is bad for Low carb dieters. The insulin spike after eating these would send most of us into an eating binge.

Megan,

I normally stick to the berry groups and some mellons (canteloupe). After my lifts I will have an apple with natural peanut butter to help the muscles recover faster. I usually pick food sources that are around 55 or lower on the GI index.
