I would agree that maybe you should experiment in cutting back on so much fruit and possibly even the potatoes. Sounds like your fatigue may be tied to not enough fat or protein. I used to think we “needed” some type of carb or starch but am realizing that we really do not. A great book explaining this is “PRIMAL BODY PRIMAL MIND”. I would suggest possibly adding some nuts to your diet in place of the at least some of the fruit….still easy, no fuss, just grab and munch. Just a thought.
