[Update 3/20/12: For references, see my post on arachidonic acid provided by all types of meat, discussing the evidence that excess dietary AA promotes inflammation including skin inflammation found in typical skin disorders like eczema and psoriasis, here. Also my post discussing the evidence that heme iron found only in meat promotes inflammation, here.]
[Update 3/20/12: I neglected to provide the reference: Whitney and Rolfes, Understanding Nutrition, 10th Edition, p. 91: "When fat is present, intestinal motility slows to allow time for its digestion."]

[Update 3/20/12: I guess I should have documented that excess dietary fat can impair liver and gallbladder function. Try searching PubMed with "high fat diet and NAFLD" or "high fat diet and NASH"and you will find plenty of evidence that high fat diets can induce fatty liver disease, like this, and this, or this, and fatty liver disease promotes gallbladder disease
[Update 3/20/12: This study showed that women with cystic breast disease and breast pain have abnormally elevated levels of prolactin when on a high fat diet, but when they switch to a low (20%) fat diet this abnormality disappears.]
[Update 3/20/12: So many people attack me for my supposedly stupid belief that a paleo diet is meat-based and low in carbohydrates. I don't get it. Loren Cordain has gone to great pains to provide evidence that both recent hunter-gatherer and ancient paleolithic era diets were low in carbohydrates. His books and those of Art DeVany and Robb Wolf all present paleo diet as reduced carbohydrate diets with limited starches.
The folks at the Journal of Evolution and Health recently got all excited by this 2011 paper by Ben-Dor et al which argues that man is an evolved fat hunter and includes the following claims
"modern hunter-gatherer (HG) groups, despite having access to fire and metal tools, also seem to have a strong preference for carnivorous foods over vegetal foods (:682), a notion also supported by a recent study  that emphasizes limited consumption of carbohydrates by present day HG groups."
"an analysis of nine HG groups for which detailed dietary information exists (:166) shows that five groups, located in an area abundant in vegetation, consumed only a meager amount of plant foods (17% of calories on average)."
I see no indication that scientists promoting paleo diet are endorsing high carb, low fat, low meat diets. I don't base my idea of paleo diet on what bloggers write, I base it on what the advocates of it have written in peer-reviewed science journals.]
Hence, my farewell to popularized paleo. I hope all “paleo,” “primal,” and “hunter-gatherer” dieters fare well in their quest for health. So long as what you do continues to work for you, keep doing it. I hope that you have the knowledge, clarity of mind, and subtlety of awareness to notice the early signs of malfunction before you succumb to something serious and beyond repair. I have a series of blogs forthcoming on this topic, outlining the Oriental medical understanding of the progression of disease from minor to major, which Chinese physicians have used for millenia to help people reverse and prevent diet-related diseases.
