"The former leader of the "Nation Of Islam", Elijah Muhammad recommended a very similar diet approach to the "Warrior Diet." Each member was required to do a water fast during the day and then they would have a feast in the evenings with their families. They did this for many reasons including mental and physical discipline and to have mental clarity during the day.
I believe that a Malcolm X stated that the most difficult instinct for man to control is not sexual desire, but desire for food. Furthermore, Malcolm X stated that if you can control hunger, then everything else will be a breeze. If you look at most members of the N.O.I, very few of them are overweight. Most are lean and in great shape."
Seems reasonable to me. I think that (probably unconsciously) we are taught to eat throughout the day in order to keep us docile. Lean hungry warriors (like in the Nation) who are pissed off would be disruptive to the little cockroaches who run Wall Street and the Banks.
