I find what you say about energy levels interesting though because, for me, it is the exact opposite. HFLC makes me feel like I am running on rocket fuel. Also, it is not just for losing weight. I am at my goal weight and continue to do it anyway. And I would still do so even if I didn't have epilepsy. (Other silly thing that bugs me is people saying that ketosis is only advisable for those with medical conditions.) It is the food I like and the energy I wouldn't want to give up. Unless I undergo some great biochemical shift, I will probably always eat this way.
