Ya know, I was just thinking something like this the other day when I read a threa about planned cheats. I feel the same was as the OP. I plan when I am going to eat something that may throw me out of Ketosis, in fact every few weeks I allow myself to eat things I normally would not on this way of eating. But I am happy with my progress, and if it slows down, I know what to watch out for. But I know personally that I would NEVER make it so long without endulging every now and again. I like not looking at it as a "cheat" we are not taking a test, we are doing something that we feel is good for us, IMO. Whos to tell you your not doing it right, it's all a personal choice.
Great set of "rules"
