I think what a lot of people find confusing about the Optimal Diet is the fact that it
isn't as rigid as it first appears. The sort of leeway that Patrick describes is already built in. It could be presented like this:
According to JK, the "recommended" foods are the best foods, and they're the only ones we need. We can live very well off them alone. The greater the proportion of them you eat, the better. Other foods are not very well-suited for our bodies.
Therefore, eat 80% "recommended" foods.
Of the "not-so-good" foods, some are just mediocre, but others are actually harmful for our bodies. For the best health, we should really avoid the harmful foods entirely.
Therefore, within the 20% "non-recommended" foods, eat 80% "acceptable" foods.
That way, you'd end up with only 4% of your foods being "inedible" by Optimal standards. I think JK would agree that this would be a very reasonable amount, as long as you didn't go by weight and add, say, 4% salt to everything.
Of course, you can't do it so mathematically in real life. And, more to the point, JK doesn't want people to have a slavish mentality. ("Bread is for slaves" is one of his mottoes.) He wants them to keep an open mind, learn the basic principles of Optimal Nutrition, and give it a try out of genuine interest. He's confident that they'll be successful, and wish to continue on this way of eating out of their own free will, not because of an external voice telling them what to do. For people in this situation, there's no question of "cheating." They've fully internalized the rules of the diet -- just like any other set of values -- and they can use their own judgment about whether or not to make an exception in a particular case. (Despite his kooky and apparently heretical views -- e.g., about original sin being caused by the apple itself -- JK still has a very Catholic way of thinking.
)
Anyway, all the talk about grinding your own sausage, etc., is kind of a red herring. If someone chooses to disregard the food lists, believing that they're basically irrelevant (and that JK was only right about the ratios, and wrong about most other things), then it's quite apparent that they aren't following the diet 99.5%, or even 80%. At best, they're doing it 50%, and they might see some minor benefits. At worst, they could actually be doing themselves harm in the long term -- in particular, because the low protein recommendations and P:F ratio were never intended to apply to vegetable proteins.
When I first joined the Dr. K threads, it seemed as if people weren't aware of the importance of basing the Optimal Diet heavily on high-quality animal fats and proteins, as they hadn't read the books, and found the web information hard to follow. All they had to go by were the P:F:C ratios, and there was a lot of confusion even about those. Now, there are several of us who have the books ... and some posters who've been on the diet for years (much longer than me) ... and Debbie is turning into a pro with the Polish/English translation engines.
So there's a great deal more information available, for those who are willing to take the time to read it. For some people, this information contradicts certain assumptions that they'd made earlier, and it doesn't necessarily suit their desires. This is too bad, but it doesn't make anyone else into an "extremist" for trying to clarify the actual principles of the diet.
And now, I have to go make some cake.
