Robb Wolf is a former research biochemist and co-owner of NorCal Strength & Conditioning. His gym is ranked as one of the top 30 gyms in America by Men’s Health. His book The Paleo Solution is endorsed by Professor Loren Cordain, the researcher who literally wrote the book on the paleo diet. The book also has endorsements from UFC light heavyweight champion Forrest Griffin and NFL player John Welbourn.
Following are some of my notes from the book. The book cites hundreds of research studies in the endnotes, but for reasons of simplicity I’m not including them here.
• Epidemiological studies show that sugar – not fat – is associated with obesity, diabetes, and cancer.
• Our hunter-gatherer ancestors were very healthy. They were as tall or taller than modern Americans and Europeans. Despite a lack of medical care, they had remarkably low infant mortality rates and had more than ten percent of their population live into their sixties.
• Hunter-gatherers were virtually free of cancer, diabetes, cardiovascular disease, cavities, bone malformations, near-sightedness, and acne.
• Hunter-gatherers had strength and endurance on par with modern athletes.
• Our genes are still nearly identical to those of the early humans who lived 100,000 to 200,000 years ago.
• Starchy agricultural crops provide a fraction of the vitamins and minerals found in fruits, vegetables, and lean meats.
• Many diseases are caused by inflammation: heart disease, cancer, diabetes, depression, Alzheimer’s disease, Parkinson’s disease, autoimmunity, infertility.
• Protein releases a relatively large amount of the hormone peptide YY, which is very satiating.
• Excessive fructose is involved in the development of obesity, depression, and diabetes.
• Eating nutritious fruits, vegetables, and good fats avoids the problems associated with eating nothing but protein.
• The paleo diet helps reduce insulin resistance, oxidation, and inflammation. Those processes are behind the development and progression of many diseases.
• Many types of cancer share a common mechanism related to hyperinsulinism. Elevated levels of insulin increase the likelihood of DNA errors that lead to cancer. Elevated insulin also derails the system of apoptosis. That’s a bad thing, since it means the elimination of the safety net that normally kills cells that become cancerous.
• Elevated insulin can also lead to prostate enlargement, polycystic ovarian syndrome, uterine fibroids, nearsightedness, fibrocystic breast disease, infertility (in both males and females), alopecia, and other problems.
• Gluten and grains are addictive and the cause of many health problems. They lead to gut irritation, increased systemic inflammation, impaired nutrient absorption, and the potential for autoimmune disease. Even quinoa irritates the gastrointestinal tract.
• Conditions that can be prevented and treated by giving up grains: celiac, rheumatoid arthritis, lupus, Sjogren’s, multiple sclerosis, reproductive issues, vitiligo, Huntington’s, narcolepsy, allergies, multiple chemical sensitivity syndrome, gall stones, dysphagia, Type 1 diabetes, schizophrenia, autism, depression, Non-Hodgkin’s lymphoma, hypothyroidism, porphyria, and more.
• The components in grains disrupt the hormonal signaling cascade. This in turn makes people feel hungry most of the time.
• Grains have molecules that fit into the opiate receptors in the brain, making them addictive.
• Dairy and legumes can also cause inflammation and gut irritation. They can aggravate autoimmune diseases.
• Eating more fruits and vegetables is a healthier alternative to eating grains.
• In every clinical trial performed, low-carb diets provide more weight loss and better cardiovascular disease prevention than high-carb, low-fat alternatives.
• Lauric acid is commonly found in coconut oil and palm oil. It has antiviral properties that fight HIV, chicken pox, cytomegalovirus, and other viruses. It also helps heal gut irritation. Populations that consume large amounts of lauric acid have low rates of cardiovascular disease.
• Stearic acid decreases Apollo protein-A (a marker of systemic inflammation).
• Oleic acid improves insulin sensitivity and glucagon response.
• Eicosapentaenoic acid is a potent anti-inflammatory, thins the blood, and blocks angiogenesis (one of the mechanisms necessary for cancer to spread).
• Docosahexaenoic acid is critical for fetal brain development and normal cognitive functions throughout life. Adequate amounts of DHA can help prevent preeclampsia, gestational diabetes, and postpartum depression. DHA has antitumor and anti-inflammatory actions.
• Linoleic acid (found in vegetable oils) is pro-inflammatory. Nuts and seeds should be eaten sparingly, since the Omega 6 fatty acids in them can lead to a pro-inflammatory state.
• Gamma linolenic acid can act as an anti-inflammatory agent.
• Arachidonic acid is critical for adapting to exercise, muscle repair, and brain function – but can be harmful in excessive amounts.
• Trans fats (aside from the small amount of trans fats found in grass-fed meat) ruin liver function, knock blood lipids out of alignment, and destroy insulin sensitivity.
• In general, omega 3 fats are anti-inflammatory and omega 6 fats are pro-inflammatory. A strategy for rebalancing in favor of good fats is to eat grass-fed meat and small wild-caught fish and also to avoid sources of omega 6 fats (seed and grain oils).
• Our hunter-gatherer ancestors only worked 10 to 15 hours per week. They spent the rest of the time socializing, traveling, and playing.
• Increasing levels of cortisol lead to a decrease in testosterone levels.
• High cortisol levels lead to the death of gray matter in the brain.
• Making the bedroom completely dark by covering up light sources is a way to improve sleep.
• Alcohol turns off the release of growth hormone, so if you drink, drink earlier in the evening.
• The NorCal Margarita (2 shots of gold tequila over ice, juice of 1 lime, splash of soda water) is better than other drinks, since it has less sugar and less gluten. The lime juice blunts insulin release and the carbon dioxide in the soda water extracts the alcohol from the drink and delivers it to your system faster.
• Owning more material goods doesn’t make people any happier.
• Exercising leads to beneficial epigenetic changes.
• Exercise benefits the functioning of hormones like growth hormone, IGF, and BDNF.
• Interval training leads to greater improvements in body composition, VO2 max, and power production.
• Good exercises include squats, walking lunges, push-ups, body rows, deadlifts, kettlebell swings, push presses, dumbbell presses, dumbbell rows, and ball slams.
• Some ways to enhance training include increasing reps, increasing the intensity, circuit training, laddering (adding one repetition to each movement of a series of movements), moving a wheelbarrow loaded with heavy items, and using a weighted backpack or weight vest.
• For people with autoimmune conditions, cutting out the following foods (in addition to grains, legumes, and dairy) can be helpful: eggs, nuts, seeds, tomatoes, potatoes, eggplants, peppers.
• Good foods to eat more of include colorful vegetables, herbs, spices, small wild fish, lean meat, olive oil, coconut oil, and coconut milk.
• Grass-fed meat is healthier than grain-fed meat.
• Grass-fed butter is fine to eat occasionally (except for people with autoimmune conditions) since it has a better fatty acid profile.
• Fruit can have too many carbs for some people to handle. Vegetables are an equal or better source of nutrients.
• Supplements are only useful when following the other guidelines in the program.
• Vitamin D can help prevent or treat cancer, autoimmune conditions, infertility, insulin resistance, Types 1 and 2 diabetes, cardiovascular disease, and inflammatory conditions.
• Low Vitamin D levels are a risk factor for contracting the H1N1 influenza virus and experiencing the cytokine storm that leads to the deaths caused by the virus. Inflammation also worsens the cytokine storm.
• People with signs of systemic inflammation, obesity, insulin resistance, or autoimmune conditions would benefit from 1 gram of fish oil for every 10 lbs of body weight (such as 25 g of fish oil per day for a 250 lb person). As the healing process accelerates, this amount can be decreased. Most healthy people are fine with a dosage between .25 g and .5 g per 10 lbs of body weight.
• Magnesium supplementation can help prevent or treat insulin resistance, cardiovascular disease, high blood pressure, osteoporosis, and chronic fatigue/fibroyalgia. Magnesium is relaxing and good before bed. If supplements paradoxically excite you, take them in the morning instead.
• Digestive enzymes can be important supplements for people who experience gastrointestinal problems, autoimmune disease, or significant systemic inflammation.
• Probiotics are important to the digestive process and in protecting the gut lining.
• Iodine can treat amenorrhea and other estrogen-related and insulin-related issues in women.
• Alpha lipoic acid and N-acetyl-L-carnitine can reverse insulin resistance, treat diabetic neuropathy, reverse symptoms of dementia, and improve concentration.
