For many years Arthur De Vany Ph.D. has been writing a book called Evolutionary Fitness on "What Evolution Teaches Us About How to Live and Stay Healthy." The diet he follows fits into my core diet definition. He may have been the first one to use the paleo diet to maximize fitness. His current site is Art's Blog on Fitness, Health, Aging, Nutrition and Exercise [archive.org].
Diet has been an important part of our evolution—as it is for every species—and we have inherited many adaptations from our Paleo predecessors. Understanding how we evolved could, in principle, help us make smarter dietary choices today. But the logic behind the Paleo diet fails in several ways: by making apotheosis of one particular slice of our evolutionary history; by insisting that we are biologically identical to stone age humans; and by denying the benefits of some of our more modern methods of eating.
The Lazy Paleo Enthusiast's Cookbook: A Collection of Practical Recipes and Advice on How to Eat Healthy, Tasty Food While Spending as Little Time in the Kitchen as Possible by Sean Robertson. The author is a recovering vegan and in the first half of the book recounts his dietary experiences using some paleo foods to restore his health. You learn that the author's main strategy is to make food in large batches which can be reheated to provide dinners for several days running. The second half of the book contains 28 recipes. Some borderline or nonpaleo ingredients do appear, but most of the recipes are more paleo than not. Published November 15, 2011.
The Hammonds—husband Joel (Timothy Olyphant), wife Sheila (Drew Barrymore), and daughter Abby (Liv Hewson)—are a typical middle-class family living in suburban Santa Clarita, with Joel and Sheila working as real-estate agents for the same firm. While showing a house to potential buyers, Sheila throws up a great deal of vomit and a strange red ball of flesh. This causes them to lose the house's listing to their co-worker, the sleazy Gary West (Nathan Fillion). After vomiting, however, Sheila begins to show changes to her personality, becoming bolder and more impulsive. She exhibits physical changes as well, such as the lack of a heartbeat, thickening blood, and a strong craving for raw meat. Their neighbor's son Eric (Skyler Gisondo) suggests that Sheila may have become a zombie, a fact the family soon confirms. The Hammonds now face the challenge of having to keep Sheila fed on human flesh without alerting the authorities, especially their cop neighbors.
There is moderately strong evidence that low carbohydrate diets are safe for most persons. However, the state of ketosis induced by the diet can occasionally progress to ketoacidosis in healthy persons. Ketoacidosis, which usually occurs only in diabetes, alcoholism or starvation, is a severe condition that requires immediate medical intervention.
The evolutionary discordance is incomplete, since it is based mainly on the genetic understanding of the human diet and a unique model of human ancestral diets, without taking into account the flexibility and variability of the human dietary behaviors over time. Studies of a variety of populations around the world show that humans can live healthily with a wide variety of diets, and that in fact, humans have evolved to be flexible eaters. Lactose tolerance is an example of how some humans have adapted to the introduction of dairy into their diet. While the introduction of grains, dairy, and legumes during the Neolithic revolution may have had some adverse effects on modern humans, if humans had not been nutritionally adaptable, these technological developments would have been dropped.
In the famous Lyon Diet Heart Study, people who had heart attacks between 1988 and 1992 were either counseled to follow the standard post-heart attack diet advice, which reduces saturated fat greatly, or told to follow a Mediterranean style. After about four years, follow-up results showed that people on the Mediterranean diet experienced 70 percent less heart disease — which is about three times the reduction in risk achieved by most cholesterol-lowering prescription station drugs! The people on the Mediterranean diet also amazingly experienced a 45 percent lower risk of all-cause death than the group on the standard low-fat diet. (11)
Oils are trickier. Loren Cordain, Ph.D., founder of The Paleo Diet Movement, breaks down which oils are healthy on the paleo diet: olive, walnut, flaxseed, macadamia, avocado and coconut oils are all allowed because they were gathered directly from the plant. While our hunter-gatherer ancestors probably did not consume flaxseed oil, it is allowed because of its content of high alpha-linolenic acid (ALA), a type of heart-healthy, anti-inflammatory omega-3 fatty acid.
Low-carb diets became popular after sensational stories of rapid weight loss, but the real reason for the weight loss is low-carb diets are so restrictive that most people who try to follow them wind up drastically reducing their caloric intake, especially that consisting of sugary foods. (That, and the fact that losing weight on the first week or two of any new diet is pretty easy, because you're just shedding water weight and the body's starvation response hasn't kicked in yet.) Proponents claim the diets make the subject want to eat less in total, and there is some evidence for this.
Most people can lose weight on almost any diet, especially in the short term. Most important to weight loss is how many calories you take in and how many calories you burn off. A weight loss of 1 to 2 pounds a week is the typical recommendation. Although it may seem slow, it's a pace that's more likely to help you maintain your weight loss permanently.
