Peter Attia, M.D. proves that self-experimentation can lead to a dramatic improvement in your health. His erudite blog posts employ solid logic and loads of scientific documentation. They can take a while to read, but they're well worth the time and effort. Peter has experimented with a "low-carb" diet and found improved health and physical performance. You won't believe what this guy eats to look so good.

Steve Kamb doles out great fitness advice.  Compared to many "in your face" fitness sites, we find his relaxed, friendly tone refreshing. Replete with catchy Star Wars, Mario, and Lego imagery, Steve invites us all to "level up" our lives by exercising in a time-efficient, low-cost way.  We joined Steve and the other rebel scum some time ago...maybe you should, too. Long live the rebellion!

This was one of the first sites we encountered that made us want to "go primal." Mark Sisson is a former elite endurance athlete that found real health by ditching "chronic-cardio", gluten, sugar, and vegetable oil, and playing Ultimate Frisbee. Mark makes us want to go barefoot, eat "big-ass" salads, and sprint on the beach. His daily blog articles are current, evidence-based, and backed by solid personal experimentation. His motivational book, The Primal Connection: Follow Your Genetic Blueprint to Health and Happiness, is fun to read and will get you living "Grok" style. He also has an amazing head of hair.

Robb Wolf is a research biochemist, power-lifter, author, and kick-boxer. He wrote the best-selling book, The Paleo Solution: The Original Human Diet. Robb has a straight-forward, no-holds-barred approach to nutrition and fitness.

Paul Jaminet, Ph.D.(astrophysics) and Shou-Ching Shih Jaminet, Ph.D. (molecular biology) have done us all a huge favor. Their seminal book, Perfect Health Diet: Regain Health and Lose Weight by Eating the Way You Were Meant to Eat, gives us a credible, science-based template from which to make dietary choices. Do yourself a favor, buy a copy and read it! The Jaminet's sparked some controversy in the paleosphere by promoting "safe-starches", but they back up their contention with a wealth of scientific data. Their website presents actionable information to improve your health. Highly recommended.

This comprehensive site is published by Chris Kresser, a licensed acupuncturist and practitioner of integrative medicine. Chris combines alternative medicine with a good measure of scientific aplomb and attention to detail. Chris has a mild disdain for traditional medicine, but is pretty even-handed when dolling out criticism. He promotes a "functional" approach that seeks to eliminate symptoms by addressing the underlying cause of ill-health, rather than simply suppressing symptoms. His website has loads of good information and he also hosts an informative Podcast, Revolution Health Radio.

Dr. Deans brings a depth of clinical experience, a wry wit, and excellent writing to the fore in her posts.  She describes herself as, "searching for evolutionary solutions to the general and mental health problems of the 21st Century." She often reviews the lastest nutritional research, especially as it pertains to mental health. We're nuts about her blog...just crazy about it...almost manic sometimes...

Melissa McEwen writes passionately about the intersection between evolutionary biology and nutrition. Her well-written blog hits topics such as women's health,  ex-veganism, and optimal foodstuffs.  She often focuses on how eating well helped heal her IBS and GERD. She finds the paleo "movement" somewhat confined, commercial, and male-dominated.. The "paleosphere" needs Melissa's common-sense and critical views.

Denise, by her own admission, has been banned by multiple vegan message boards.  She demolished the China study with several hard hitting blogs posts and videos. Not that she has it out for vegans or anything, she's just an optimal nutrition nerd that occasionally ruffles some feathers.  She posting less frequently recently while she writes her book, Death by Food Pyramid. (Awesome title.)

A maverick of sorts, Jack Kruse would have you eating seaweed and sardines while pondering the intricacies of hypothalamic signaling - all whilst you sit in a tub of ice-water.  Yes, seriously. Dr. Kruse's posts could be perceived as rambling and paternalistic, but we've found them helpful in many ways, especially as it regards lab testing and hormones.  Dr. Kruse pulls inspiration from genetics, human physiology, biochemistry, and physics in an attempt to discover the optimal human diet and patterns of daily living.  Speculative? Yes. Controversial? Yes.

It often only take 20 seconds of courage to overcome many fears, obstacles, phobias, etc. Come on, get your beserker, bloodwrath, trance-like fury game on!

Here's the link to f.lux (dims your monitor based on time zone and latitude).

Dr. Kruse discusses EMF exposure, osteoporosis and the crystalline semiconductor effect in bone.

Vitamin D deficiency is correlated with higher risk of heart attack. Chris points out that adequate Vitamin A can protect against vitamin D toxicity. Fermented Cod Liver Oilis a good way to get Vitamin D and A.

Suggests that up to 10,000 I.U. daily is unlikely to cause toxicity.

Good overview of Vitamin D issues with many helpful references.

Helpful fact sheet about Vitamin with links to multiple original studies regarding Vitamin D deficiency, toxicity, and optimal levels.

Learn how Vitamin D helps women protect against cancer and osteoporosis. It boosts infertility. Vitamin D also helps Polycystic Ovarian Syndrome.

Learn the basics of Vitamin D toxicity, UV exposure, supplementation, Vitamin D deficiency, and essential co-factors for optimal vitamin D function.

Mark Sisson wants to change the health of millions of people.  He’s a popular blogger, nutrition expert, and formerly a top-ranked endurance athlete who’s exercise and training routine left him with irritable bowel syndrome, chronic upper respiratory infections, and chronic osteoarthritis. Mark re-built his health with “The Primal Blueprint” – a lifestyle and eating strategy that “optimizes gene expression.” Here’s an interview between Dr. Andreas Eenfeldt and Mark Sisson.

Dr. Cordain is a Professor in the Department of Health and Exercise Science at Colorado State University in Fort Collins, Colorado. His research focuses on the evolutionary and anthropological basis for diet, health and well being. Dr. Cordain has published scientific papers that look at hunter-gatherer diets around the world.  Dr. Cordain’s research team explores the connection between diet and increased intestinal permeability and how it triggers  autoimmune disease, particularly multiple sclerosis. He lectures extensively about “Paleolithic Nutrition” and has written three books: The Paleo Diet, The Paleo Diet for Athletes , and The Paleo Answer.

Robb Wolf is a former research biochemist and the author of New York Time Bestseller The Paleo Solution: The Original Human Diet. He’s also a gym owner, kick-boxer, and former California State power-lifting champion. Robb has an informative website and he’s an all around great guy. (I haven’t actually met Robb Wolf, or Pat Sajak, for that matter, but I’m assured that they pretty decent guys, if I don’t say.) Seriously, Robb I’d love to meet you sometime. You helped me change my whole approach to comida, man. In the video, Herr Profesor Wolf gives us a detailed breakdown of the Paleo Diet.

Your body cannot live without saturated fat. Eat more butter and coconut oil. It's a lot healthier than soda.

Contrary to conventional wisdom that saturated fat is going to clog your arteries and kill you, Paul Jaminet reviews a large study (over 50,000 participants) that shows the health benefits of saturated fat.

It's not saturated fat we have to fear, but the trans-fat and PUFAs the USDA is shoving down our throats.

Bottom line: "...there is no significant evidence for concluding that dietary saturated fat is associated with an increased risk of CHD or CVD."

Pass the butter, please.

Dr. Miller walks us through the Keys fiasco, the substitution of Crisco for lard, the McGovern Report, etc. He then deconstructs the lipid hypothesis and points out why avoiding saturated fat is not a good idea.

These guys say you lose belly fat, improve cardiovascular, lung, brain, liver, and bone health as well as improve nerve signaling by, wait for it...eating more saturated fat!

Video and slide show from Peter Attia, M.D. on how flimsy the evidence against cholesterol and saturated fats actually is. He reviews the shoddy research and political chicanery allowed us all to "believe one of the most pervasive myths in the entire field of nutrition."

Mark highlights where conventional wisdom went wrong on saturated fat by debunking Ancel Keys data, showing how high saturated fat amongst indigenous cultures (Masai, etc.) doesn't lead to heart disease, and critiques Loren Cordain's position on saturated fat.
