Taking them away may make a person feel awful. If Justin's friend is in ketosis, the fatigue could be a common symptom of electrolyte depletion from the diuretic effect of the diet. In short, taking away the Forbidden Fruits can increase one's need for salt and potassium. This is precisely the problem that results from thinking of the paleo diet in terms of what it excludes. There is good clinical evidence that the fatigue that commonly results from a ketogenic diet is avoided by extra salt. According to Phinney (who conducted studies of the response of endurance athletes to ketosis), 4 or 5 grams/day of supplemental salt is needed to avoid the fatigue. I realize that added salt is itself considered a Forbidden Fruit, but this injunction does not take into consideration the peculiarities of ketosis (How typical is ketosis among primates?). The details matter. Incidentally, I have recently tried the procedure of soaking bacon in water overnight. I find that the soaked bacon is still fairly salty (which I like). Todd Moody
