I have been on the primal blueprint eating plan for about a month now.

I have been very tired from the very start. Initially I thought it was because my body needed to learn to burn fat as a source of energy, but after a month, I feel no better. I am so tired that I cannot make it through the day without at least three cups of coffee. I am also totally unable to go to gym, because of the fatigue.

I also feel that my concentration powers have really suffered and I struggle to remember even the basics.

Do you have any advice for me to boost my energy levels and concentration / memory? Am I doing something wrong perhaps? Weight loss is also not really happening.

Thanks
