Very good post, I am all for experimenting with different diets. I have found a good diet that works very well for me and I'm always trying little experiments with small changes in diet, lifestyle, herbs to see if I can make more improvements. I think that instead of people following specific diet recommendations, they should try to experiment like you are and see if they can find something that will help.
Chronic fatigue is very, very bad and it seems the main cause of many diseases. In my view energy is basically our life source our vitality. The lower the energy, the less the body is able to function properly, digestion is impaired, candida and other harmful bacteria grow and multiply, organs cannot be properly maintained and repaired.
