I eat what could be considered a "paleo" diet, however, I don't label myself "paleo" or "primal"; it all seems a bit too cultish to me. I follow the basic principles of the diet: no refined or processed carbohydrates, grains, and limited legumes. I eat a lot of meat, and probably am keeping D'Artagnan in business. I am not fanatic or obsessive about it, though. The term "orthorexia" implies an unhealthy obsession with your health. You will end up with more issues from stress and anxiety worrying about everything that you're putting into your mouth then if you actually ate everything you're "supposed" to; the idea is to be practical, but still exercise good judgment and common sense with the knowledge you have of what constitutes a healthy diet and what you can tolerate. Listening to your body and the signs it gives you is essential. And to echo another post, just because cavemen did something does not necessarily mean we should as well. I enjoy cooking and fine dining, and when I go to a restaurant, I allow myself to enjoy it. Fussing over the polyunsaturated fats in the canola oil the chef is using, or whether the beef you're eating is grass fed is just not worth the overall hassle and worry. I've learned to take a moderate approach and just be mindful of it all. If I eat something I'm not supposed to, it's going to be in a chef's tasting menu, or something of high quality that is really worth it. Eat slow, savor what you eat, and you will be satisfied with much less. Eating the foods we evolved to eat is most likely the healthiest diet. It does not have to be done in a fanatical or obsessive way, and it shouldn't be thought of as a "diet" in the current sense of the word. It's just a matter of living with common sense.
