I've also been thinking about the concept of a "cheat day" or "cheat meals." The longer I've been at the iron game, the more I've come to realize that extreme, rigid adherence builds extreme behaviors, which in the long-run, can be detrimental. I think the Anabolic Diet is a perfect example of this.
I'm sorry, but I think gaining six or seven pounds in a day and gorging yourself on food is not a healthy way to live. Granted, the science may contradict this point, but for me personally, I was very unhappy "waiting" for my day to cheat when I was on a low-carb diet similar to it.
In just the past few weeks, I've really adapted, and thrown out the idea of cheating. Rather than saying "okay, I need to hit X&Y&Z macro and I can only have these foods in these combinations in these quantities at these days," and sticking to this rigid schedule almost obsessively, I've begun to approach eating in a much healthier fashion. If I want a bowl of whole grain cereal with skim milk in the evening, I have it when the craving hits. Obviously I make sure I really want it, by downing 40g or so of Grow! powder and then brushing my teeth. If the craving is still there, I indulge.
I find that indulging at the time, rather than building up this immense amount of stress over a single MACRONUTRIENT over the course of a week has led to positive psychological and health benefits. I find the need to gorge or binge disappears. I'm satiated and my brain shuts off and feels happy and life goes on.
Most of my cravings are for good foods anyways, and they happen fairly infrequently (once every 3 to 4 days). I think JB is spot on with his 90% rule (10% transgression isn't going to unduly effect your progress). Good thread guys. I think there's a distinct lack of discussion concerning the psychological and mental effects of our lifestyle choices, which demand far more discipline (we're literally fighting against our natural instincts at every turn) than 97+% of the population will ever experience.
