I’m finding that I have low levels of energy in the evenings only. Could this be because my body is still adapting to primal living and adjusting to less carbohydrate intake? How long does this usually last? I’m also finding that after my sessions of intense Muay Thai training, I don’t have the energy the next day to do much of anything regarding exercise. (My Muay Thai routine includes two hours of jumping rope, calisthenics, ab work, sparring, focus mitt work and pad work in 92-93 degree heat three days a week.) Any suggestions?
