The caricature of the Paleo dieter is a Flintstone-esque cave man in loincloth gnawing on a giant, raw woolly mammoth femur bone. Fun? Yes. Accurate? No. While grass-fed meat from ruminant animals is certainly a healthy "Paleo food," it by no means constitutes the majority of a typical Paleo diet. I personally eat far more seafood than red meat, and actually derive more calories from coconut products — a true Paleo staple — than animal products.
Paleonutrition by Mark Q. Sutton, Kristin D. Sobolik, and Jill K. Gardner is the analysis of prehistoric human diets and the interpretation of dietary intake in relation to health and nutrition. This is a substantial text that combines background to paleonutrition, an extensive bibliography, a discussion on methods, and case studies. Published February 23, 2010.
The Stone Age Diet: Based on in-depth studies of human ecology and the diet of man by Walter L. Voegtlin. This was self-published back in 1975. Only a couple hundred copies were printed and distributed to friends and relatives. No one knew the book existed until some years later. In no way is he the father of the paleo diet. It is impossible to purchase. Apparently his descendents are planning a reprint, though the book is poorly written and not based upon factual anthropological information that even was available then. We have put up his Functional and Structural Comparison of Man's Digestive Tract with that of a Dog and Sheep. And a PDF can be found here.
Autoimmunity is a process in which our bodies own immune system attacks “us.” Normally the immune system protects us from bacterial, viral, and parasitic infections. The immune system identifies a foreign invader, attacks it, and ideally clears the infection. A good analogy for autoimmunity is the case of tissue rejection after organ donation. If someone requires a new heart, lung kidney or liver due to disease or injury, a donor organ may be an option. The first step in this process is trying to find a tissue “match”. All of us have molecules in our tissues that our immune system uses to recognize self from non-self. If a donated organ is not close enough to the recipient in tissue type the immune system will attack and destroy the organ. In autoimmunity, a similar process occurs in that an individuals own tissue is confused as something foreign and the immune system attacks this “mislabeled” tissue. Common forms of autoimmunity include Multiple Sclerosis, Rheumatoid Arthritis, Lupus, and Vitiligo to name only a tiny fraction of autoimmune diseases. Elements of autoimmunity are likely at play in conditions as seemingly unrelated as Schizophrenia, infertility, and various forms of cancer.
Eat generous amounts of saturated fats like coconut oil and butter or clarified butter. Beef tallow, lard and duck fat are also good, but only if they come from healthy and well-treated animals. Beef or lamb tallow is a better choice than lamb or duck fat. Olive, avocado and macadamia oil are also good fats to use in salads and to drizzle over food, but not for cooking. For more information, have a look at our beginner’s guide to Paleo and fat.
But listen--we'd both been relatively inactive for years and each about 25 pounds overweight. Between the two of us we lost 34 lbs in 30 days and we are still going to keep up a serious commitment to Whole 30, with a few supplemental treats now and then. We feel better, we have new confidence about getting dressed in the morning, and we're more fit than in years, mostly because we have the energy to do more. The amazing thing is that you will NOT feel hungry if you hang in there and consistently prepare foods as per the cookbook/menus. There is also a very supportive and helpful forum online to supplement the book.
Another 2014 study in the European Journal of Clinical Nutrition compared the effects of the Paleo plan to those of a standard low-fat diet on 70 obese, postmenopausal women. After six months, the Paleo group lost 14 pounds on average, while the other group lost nearly 6 pounds. After a year, the Paleo group had lost 19 pounds on average, and the low-fat dieters had dropped 10 pounds. A year later, both groups had regained some weight: The Paleo group was still down 10 pounds, while the low-fat group had dropped an average of more than 6 pounds.
The NY Times had a blog article on Good News on Saturated Fat which is reporting on Gary Taubes's interpretation of the new report in The New England Journal of Medicine on a two-year diet experiment in Israel. A followup is the post The Fat Fight Goes On where Gary rebuts the arguments against the study. And here's a good interview with Taubes (and includes a good summary): Gary Taubes on Cold Fusion, Good Nutrition and What Makes Bad (and Good) Science.
Ever start a diet and get immediately discouraged when the number on your scale hasn't budged after a week or two? Whole30 forbids weighing yourself — a practice which can help shift your mindset to how you're feeling as your success metric. "The scale shouldn’t drive your mood, food choices or overall mindset," says Amy Shapiro, RD. "Continue to live a healthy life and measure how you feel energy and clarity wise." Which means being honest with yourself about how your body feels after going to town on that cheese plate. One of the biggest realizations for me was how much clearer and more energetic I feel when my weekend diet doesn't consist of vodka-sodas and takeout food.
A better idea is to reincorporate small amounts of non-Whole30 foods one at a time, waiting a few days before adding something else back in. For instance, after day 30, continue to follow the diet, but have yogurt for breakfast and add some cheese to your salad. Do this for a few days and see if any symptoms pop up. If they do, you know that dairy is problematic for you. Then, try the same thing with another food group, like gluten-free grains. Reintroducing gluten-free and gluten-containing grains separately can help you determine whether you have a gluten sensitivity.
When the 30 days are up, you can continue eating this way or gradually add some of the foods back in one by one to see which may have been causing your issues. Many people who become devotees of the lifestyle stick to a Paleo diet afterward (The Paleo diet is interpreted differently by different people, but in general, it’s a less strict, long-term lifestyle version of the Whole30).
To make the curry sauce, melt the cooking fat in a saucepan over medium heat and swirl to coat the bottom of the pan. When the fat is hot, add the onion and cook, stirring, until translucent, 2 to 3 minutes. Add the garlic and stir until it becomes aromatic, about 30 seconds. Add the curry powder and stir for 15 to 20 seconds, taking care that the garlic and curry powder don’t burn. Add the tomatoes and simmer until thickened, about 5 minutes. Transfer the contents of the pan to a food processor or blender and puree until smooth. Pour into a mixing bowl and let cool. Mix in the coconut cream, salt, and pepper.
In response to these criticisms, CrossFit, Inc. claims, “CrossFit is relatively safe even when performed with poor technique, but it is safer and more effective when performed with good technique.” CrossFit, Inc. also claims risk for injury can be reduced by properly scaling and modifying workouts, a concept taught on its website and at the CrossFit Level 1 Trainer Course.
