Is the 40 Hour Work Week a Thing of the Past? | The Paleo Diet

America is somewhat (in)famous for its “work hard, play hard’ motto,1 whereas Europeans typically work less and relax more.2 As America’s health rapidly declines, many Americans are starting to wake up and realize all those extra hours aren’t really worth it.3, 4, 5 One recent example of this is a Portland-based company Treehouse, who have started a 32 hour work week trend for their employees without slashing their benefits.6 Interestingly, they have found that employees are more productive on this schedule.7 We have to ask: is this feasible for everyone?

Then there is the story of Ultra Romance – a 35 year old man who only works six months out of the year, spending the other six months riding his bicycle around the world, and living off of a mere $10.00 per day.8 While certainly not a mainstream idea, part of me thinks that he just might be on to something. He claims modern life is just too stressful, and often I’m inclined to agree with him. Scientific literature supports his claims, as well.9, 10, 11 Though there are other parts of his story that are even more fringe-like (he’s never owned a car, and he only got a bank account to buy and sell bicycle parts on eBay), at heart he may be more in tune with our Paleo ancestors, than we are.

But believe it or not, capitalism used to be even more demanding on the human psyche, with a 48 hour work week being a thing of the not-too-distant past.12 That clearly seems like too much to expect of human beings. It cannot be good for us to work that much…right? Correct.13 To put it simply, all that constant work is not great for our brain or body.14, 15, 16 And as life outside of the workplace becomes increasingly demanding it is a healthy question to ask: “how much is enough?” One alarming trend that has occurred only over the last 40-50 years is a completely diminished sleep quantity, across the board, for all genders and age groups.17 Not getting enough sleep can have long term negative consequences, on a variety of biomarkers of wellbeing.18, 19

Interestingly, before capitalism, most people did not work very long hours at all.20 Capitalism may have raised income levels, but precious time (the one thing you can never get back) was lost. Was this a good trade? As we reach the apex of technology and with the potential for nearly everything to be automated, we must reexamine our lifestyles.21

If you don’t believe me, believe the data. Never before have we seen such a widespread obesity pandemic.22 Never before has healthcare and diabetes been costing us so much.23 Happiness indexes are highest in the Nordic countries – countries which have vastly different work and leisure habits than we do.24

Hopefully I’ve given you some food for thought. We are undoubtedly in tough times. There is vast economic disparity, great economic instability, rapid advancements in technology, and hyper-stimulation of our senses. But our basic biology has not changed. We are still humans who require relaxation, 8-9 hours of sleep, high quality food, and smart amounts of physical activity. Our Paleo ancestors may have been right all along – and they certainly did not work a 40 hour week.

Chronic Fatigue and The Paleo Diet | The Paleo Diet

Myalgic encephalomyelitis, commonly called chronic fatigue syndrome (ME/CFS), is an incapacitating condition marked by disabling fatigue of at least six months, accompanied by numerous rheumatological, infectious, and neuropsychiatric symptoms.1 However, in our modern day nearly 4 million people 2 struggle with these symptoms that impact their ability to fully engage in daily activities.  Exercise can help fight common fatigue, while even minor efforts at physical activity lead to a significant worsening of symptoms for ME/CFS patients. This often encourages ME/CFS patients to cope with their illness by completely avoiding physical activity.3,4

Western medicine has offered little support for effective treatments options, which have included self-managed exercise programs and psychotherapy, and many practitioners fail to recognize ME/CFS as having a physical cause, believing the condition is only psychosomatic.5 Fortunately, researchers have just discovered that there are actual plasma biological markers in individuals with early ME/CFS symptoms. Specifically, the data shows a significant activation of both pro-and anti-inflammatory cytokines, the cells aiding in communication of immune responses triggered by inflammation, infection and trauma.6 This data stands to offer both new diagnostic tools, as well as treatment options to reduce the severity of ME/CFS.7


Nutritional deficiencies can contribute to the clinical manifestations of ME/CFS, and also can impact the healing processes.8 The Paleo diet is nutrient dense9 and exceeds the governmental requirements for over 13 nutrients lacking most in the Standard American Diet (SAD).10 Follow the prescriptions in The Paleo Diet, while focusing on the following recommendations to target healing.


Antioxidants have therapeutic potential to reduce oxidative damage, which is often shown to be high in those with ME/CFS.11 Elevated concentrations of inflammatory cytokines might indirectly cause diminished antioxidant capacity by inhibiting albumin transcription in the liver.12 Therefore, it is important to replenish the body with dietary sources of glutathione-rich foods, as glutathione is required to properly utilize other antioxidants such as vitamins C, E, and selenium and carotenoids.13,14


Magnesium is necessary for over 300 biochemical reactions in the body. Stress hormones tend to deplete magnesium levels,15 which have also been shown to be decreased in ME/CFS patients, despite adequate dietary intake of magnesium.16 Magnesium supplementation from naturally rich sources, such as avocados, dark leafy greens, and nuts,17 has been shown to improve energy levels, emotional wellbeing, and reduce pain in ME/CFS patients.18


Low levels of essential fatty acids (EFAs), which are often linked to immune, endocrine, and sympathetic nervous system dysfunctions,19, 20 appear to be common in individuals with ME/CFS.21 The Paleo Diet mimics our hunter gatherer ancestor’s dietary intake of omega-6 to omega-3, with a ratio of 2:1 or 3:1, as opposed to the modern diet, which has been estimated at 10:1 or 25:1.22 Pastured meats and wild fish, as recommended on the Paleo Diet are naturally higher in omega-3 fatty acids and support anti-inflammatory actions within the body.


Stress contributes to the pathology and clinical symptoms of ME/CFS.23 The greater number of stressful life events predicts a worse functional and fatigue symptom profile24 and those who recover from ME/CFS for over one year report lower levels of life stress than those who did not recover.25 The lifestyle choices of hunter-gatherers differ from those of modern man in that there was adequate rest and recovery from both physical endeavors and mental feats. In addition to getting a solid night’s sleep, spend time outdoors each day, turn off technology early and practice mediation or other stress reducing activities to support your Paleo Diet lifestyle.

Your Dietary Fix for Stress: Paleo Diet or Nordic Diet | The Paleo Diet

In November of 2014, the International Journal of Obesity published a study conducted by Swedish researchers comparing Paleo-inspired diets with those based on the Nordic Nutrition Recommendations (NNR).1 The NNR are comparable to the USDA’s dietary guidelines, emphasizing low-fat dairy and cereal grains and recommending a macronutrient distribution of 55-60% of calories from carbohydrates, 25-30% from fat, and 15% from protein. The macronutrient distribution used in this study to represent the Paleo diet was 30% carbohydrates, 40% fat, and 30% protein.

The researchers grouped 49 overweight or obese postmenopausal women into the Paleo and NNR groups, tracking their progress over two years. They were primarily serving how these diets influence glucocorticoid metabolism. Glucocorticoids are stress hormones that modulate various metabolic, inflammatory, and cardiovascular processes.2 Abnormal glucocorticoid metabolism is associated with metabolic syndrome and obesity.

Cortisol, the principal active glucocorticoid, is secreted by the adrenal glands and converted to cortisone, the inert form.3 One of the enzymes responsible for this conversion is called 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1). Obese individuals demonstrate increased activity of 11β-HSD1 in subcutaneous adipose tissue (SAT), which is fatty tissue directly under the skin. The researchers hypothesized that diet-induced weight loss results in decreased expression of 11β-HSD1 in SAT and thus a reversal of the abnormal glucocorticoid metabolism common to obese patients.

The study’s participants were observed at baseline, after 6 months, and after 24 months. Both groups lost weight and decreased BMI, waistline measurements, and total body fat throughout the study. The Paleo group had greater reductions after 6 months, but after 24 months there were no significant differences between the groups. Both groups also demonstrated decreased activity of 11β-HSD1 in SAT. The researchers noted, “We did not find any major difference between diets on glucocorticoid metabolism.”4

So what does this study tell us? The Paleo diet performed better than NNR after 6 months, but after two years, it seems neither diet had any advantages over the other. It’s important, however, to look closer at the structure of the study. Every two months, participants attended sessions with dietitians to ensure compliance with their respective diets. Food journals and urine samples were used for monitoring and measuring food intake. An anomaly, however, pointed out by the researchers, was that urinary nitrogen levels were not higher in the Paleo group (as they should have been) at any time during the study, “indicating that the actual intake of protein was similar in both diet groups.”5 The Paleo group, however, was instructed to eat 30% of calories as protein, double the amount of the NNR group.

Also, Paleo participants were instructed to eat 40% of calories as fat, “with a high proportion of mono- and polyunsaturated fatty acids (MUFAs and PUFAs).” An authentic Paleo diet, however, would have higher proportion of saturated fatty acids and MUFAs, with only very small amounts of PUFAs. So, the “Paleo diet” and the low-fat, high-carb, grain-centric diet fared similarly, but were Paleo participants following an authentic Paleo diet? This seems doubtful. Nevertheless, this study represents an important advance in our understanding of how diets influence stress hormones. Follow-up studies will hopefully ensure greater compliance to authentic Paleo diets.

Metabolic Syndrome and the Brain

Metabolic syndrome is an increasingly prevalent problem, not only in developed countries, but in developing countries as well.1, 2 The cluster of risk factors, which comprise metabolic syndrome, are usually thought to be strictly related to obesity.3 However, research shows that metabolic syndrome is correlated with severe cognitive dysfunction as well.4, 5 Risk factors for metabolic syndrome are defined as: raised blood pressure, dyslipidemia (raised triglycerides and lowered high-density lipoprotein cholesterol), raised fasting glucose, and central obesity.6, 7
Definition of Metabolic Syndrome

So what exactly causes metabolic syndrome? Scientific literature suggests Westernization of diet is part of the problem.8 When we look at the brain impairment associated with metabolic syndrome, there are a variety of proposed causative mechanisms including impaired vascular reactivity, neuroinflammation, oxidative stress, and abnormal brain lipid metabolism.9

Hypothesized Brain Vascuar Reactivity

Model describing hypothesized brain vascular reactivity abnormalities resulting in brain impairments.

Interestingly, at least one study has shown that men are more affected, cognitively, than women.10 A comprehensive study on metabolic syndrome and the brain, found rats fed an omega-3 deficient diet exhibited memory deficits, which were further exacerbated by fructose intake.11 This demonstrates that systemic inflammation and high sugar intake, specifically fructose, may be two possible precursors to cognitive decline, as well as obesity. It is also important to note the prevalence of a hypercaloric diet consisting of a high sugar intake and highly processed foods has coincided with an exponential rise in diabetes and metabolic syndrome, as well as cardiovascular diseases and cancer.12 Nutrient intake directly correlates with brain volume as shown in the Nutrient Biomarker Pattern Score Diagram.13

Metabolic Syndrome Nutrient Biomarker

Nutrient biomarker patterns and volumetric MRI (n = 42) Total cerebral brain volume (A, B) expressed as a % of total intracranial volume; white matter hyperintensity volume (C) includes periventricular and subcortical deep signals expressed as a % of total cerebral brain volume; x-axis represents the standardized score for NBP1-BCDE, NBP8–trans fat, and NBP5-marine ω-3 patterns.

Metabolic syndrome and cognitive dysfunction can further be explained via a 2011 study, which specifically showed how omega-3 deficiencies during pregnancy could affect multiple cognitive factors of new born offspring.14 Omega-3 deficiency was also shown to have effects on levels of brain-derived neurotrophic factor, an important gene in regulating stress, and in the biology of mood disorders.15 The image below shows how inadequate omega-3 intake can lead to cognitive and mood dysfunction.

Metabolic Syndrome Diagram 4

Schematic representation for potential pathways by which n-3 dietary deficiency may enhance vulnerability to cognitive and mood disorders.

Omega-3 fatty acid deficiency, specifically an inadequate dietary intake of docosahexaenoic acid (DHA), is a recurring problem across these studies. DHA is vital to brain development, mood, and many other important physiological and cognitive functions.16 Other studies have shown brain tissue decline even early in the metabolic syndrome.17 High fructose consumption with an omega-3 deficient diet disrupts membrane homeostasis.18 Metabolic syndrome and brain dysfunction is even seen in adolescents, despite their much shorter lifespan.19 Researchers stated adolescents with metabolic syndrome show significantly lower arithmetic, spelling, attention, and mental flexibility and a trend for lower overall intelligence.

The takeaway: Westernization of diets, specifically over consumption of fructose, is closely linked with developing metabolic syndrome and its accompanying cognitive impairment. Deficiencies in anti-inflammatory omega-3 fatty acids have also been shown to correlate with metabolic syndrome and cognitive decline. A simple path to a healthier life is to adopt a Paleo Diet, which is generally extremely low in fructose, and high in omega-3 fatty acids. By giving your brain (and body) the right nutrients, you can thrive in all areas of life.

Gut Healing | The Paleo Diet

Many of those that have made the switch to The Paleo Diet, previously subsisted on a Standard American Diet (SAD) that relies heavily on grains, dairy, simple carbohydrates, sugars, and unhealthy oils. A diet rich in SAD foods can contribute to gut dysbiosis or “leaky gut” which can lead to autoimmune disorders and other ailments such as chronic fatigue, inflammatory bowel disease, rashes, diabetes, mental disorders, and other health related problems. To add insult to injury, the modernized human being has typically had their fair share of gut damaging antibiotics and prescription drugs which only serve to further throw off the intricate balance in one’s digestive tract.

If you have yet to achieve success after adopting your Paleo lifestyle, there is a good chance that your gut functioning is not up to par and your digestive system could be allowing toxins into your bloodstream and preventing adequate nutrient uptake regardless of how healthy you may be eating.

To support immune function and overall well being one must account for the importance of gut health. Fortunately, there are many foods and lifestyle practices you can adopt to restore your gut’s equilibrium.

Gut Healing Foods

As obvious as it may seem, the gut should be thought of as the primary interface between the human body and the environment. Every food that is put into your system will create a reaction in your gut. Certain foods will increase gut permeability with long term exposure, thus allowing normally digested food particles into the bloodstream invoking an immune system response. Over time, this response can lead to the formation of autoimmune illnesses and other health issues. Avoid these foods on a gut healing protocol:

  • Grains
  • Legumes
  • Dairy
  • Sugars
  • Unhealthy oils (corn, vegetable, soybean, cottonseed)
  • Alcohol and caffeine
  • Excessive carbohydrate consumption

Individuals with autoimmune disease may want to limit or omit:

By removing the foods outlined above, you should be able to reduce overall body inflammation and assist in restoring gut health.

Certain foods, however, should be incorporated into your Paleo Diet to accelerate the healing process.

Gut Healing Foods

Probiotic rich foods are essential. The gut is home to roughly 100 trillion organisms, and many gut related problems stem from loss of gut flora diversity. These foods are tremendously rich in probiotics and should be consumed regularly:

  • Fermented vegetables (sauerkraut, kimchi)
  • Kombucha
  • A multi-species dairy-free probiotic supplement can also be equally beneficial

Heal the Intestinal Wall

  • Bone Broth, rich in glycine, gelatin, and glutamine which is essential for intestinal repair
  • Fermentable fibers, like sweet potatoes
  • Healthy fats sources including pasture raised animals, avocado, coconut oil, pure olive oil
  • Omega-3 rich foods like seafood and salmon

Finally, a vital part of gut health is to be able to adequately manage stress. Excessive stress results in heightened cortisol levels which can over time wreak havoc on hormone functionality and other bodily processes including gut functioning.

It is important to avoid chronic stress and to incorporate activities you enjoy in your day-to-day. Activities such as hiking, meditation, playing with your kids, or socializing with friends and family are all great ways to reduce stress.

Stick to these tips and you will be well on on your way to achieving a healthy gut!
