I know fruit is healthy, but if I snack on just fruit I do not get any energy. Fruit is still sugar even though it is natural sugar. I need to have some protein and fat with all of my meals and snacks in order to feel energized. Potatoes also wipe me out, when I am having trouble sleeping I will actually eat a baked potato before going to bed and I sleep much better. This is just me and I don't know if it would work for you. One easy way to get some protein and fat is try adding almond butter to your fruit. I love it on apples.
