Glycemic index/load is more important when you're eating a high-fat diet, since if your blood is too fatty, it will interfere with the uptake of sugar by your cells. This can cause blood sugar problems and exacerbate diabetes symtoms. That's why I don't recommend adding fruit to a high-fat diet (which is what the average American eats by default -- about 42% of calories from fat). If you get 30%+ of calories from fat, your bloodstream will constantly be filled with excess fat.
But when your diet is low-fat, your body shouldn't have a problem with lots of fresh fruit. Most fruits are low-GI foods, including bananas, and they come packaged with plenty of water and fiber to help your body process the sugar at just the right rate.
Be careful not to confuse the initial adaptation period with the long-term effect of this diet. It's normal to feel lousy for the first week or two as your body adjusts.
