Paleolithic Diet
The Paleolithic Diet (“Paleo” is a common abbreviation) is based on eating foods that our Paleolithic ancestors ate. The “Paleolithic” refers to the Paleolithic Age, which is a formal time period on Geologic Time Charts from about 2,500,000 years ago to about 10,000 years ago. The premise is that during the Paleolithic, we evolved a specific genome that has only changed 0.01 per cent in these last 10,000 years. However, during this recent time span mass agriculture, grains/grain products, sugars/sugar products, dairy/dairy products, and a plethora of processed foods have all been introduced as a regular part of the human diet. We are not eating the foods we are genetically and physiologically adapted to eat (99.9% of our genetic profile is still Paleolithic); and the discordance is an underlying cause for much of the “diseases of civilization”, “syndrome X”, obesity, and  “diseases of old age” that are so epidemic in our society today.Read More About the Paleolithic Diet

As Dr. Cordain and others’ scientific research reveal – the evolutionary, genetic, and clinical evidence point to a natural (i.e., unprocessed foods), omnivorous diet as the healthiest way to eat. Dr. Cordain’s research shows that 70% of the average caloric intake of Americans is from foods that did not even exist for our Paleolithic ancestors. This discordance is having tremendously negative health consequences for our society as a whole.

Our genes determine our optimum diet, and our genes evolved according to the environments in which our ancient ancestors lived, including the foods they ate. Our Paleolithic ancestors did not eat just one single diet, but rather they ate within a range of natural, unprocessed diets – depending on variables like geography, climate, competition, ecologic niche, season, and glaciations. All of these Paleolithic diets did share some universal characteristics, though

Nutrition is the foundation for all athletic development and essential for achieving elite fitness and health.  The CrossFit nutrition prescription in it’s simplest terms is “Eat meat and vegetables, nuts and seeds, some fruit, little starch, and no sugar.”  This ensures that you are eating “real food,”  the food that our hunter-gatherer ancestors have eaten for millions of years, and avoiding the processed “edible food-like substances” that come in boxes, bags and packages.

Evolution has not kept pace with advances in agriculture and food processing resulting in a plague of health problems for modern man. Coronary heart disease, diabetes, cancer, osteoporosis, obesity and psychological dysfunction have all been scientifically linked to a diet too high in refined or processed carbohydrate.  Many have observed that keeping your grocery cart to the perimeter of the grocery store while avoiding the aisles is a great way to improve health.  Real food is perishable. The stuff with long shelf life is all suspect.  An easy rule is “If you can hunt it or gather it, you can eat it.”

If you follow these simple guidelines you will benefit from nearly all that can be achieved through nutrition.

Reclaim your health by understanding the diet that is genetically coded in all humans, the Paleo Diet.

We have a modern snap shot into the effects of the Paleo Diet with the last 84 tribes of Hunter Gatherers on earth. These Hunter Gatherer tribes have survived relatively untouched since the dawn of time; we know these groups are muscular, strong and healthy. They have perfect eyesight and straight teeth and are free from diabetes, obesity, cancer and other problems plaguing the modern world. Since we are genetically identical to our ancestors of 2 million years ago and for the last 7 million years we have been genetically coded to eat a certain way, a diet that is based on animal based proteins, fruits and vegetables and healthy fats is the key to health. A modern diet based on grains, processed foods and sugars has taken us down a path of sickness, illness and obesity.


What Should I Eat?

Protein:  Fish, Meat, Chicken, Eggs
Carbs:  Fruits and Veggies
Fat:  Nuts, Seeds, Avocados, Olives and Oils

What Foods Should I Avoid?
Anything that doesn’t exist in nature, or has been processed.  Corn, rice, bread, candy, potato, sweets, sodas, and most processed carbohydrates. Processing can include bleaching, baking, grinding, and refining. Processing of carbohydrates greatly increases their glycemic index, a measure of their propensity to elevate blood sugar.

What is the Deal With Hormones?
Hormones regulate how the body stores and releases fat.  The hormonal response your body has to food determines whether you store fat or burn it.  As far as hormones are concerned, food is a drug–a very powerful drug.  Consuming low-glycemic foods, that keep insulin levels steady, will allow stored body fat to be burned as a fuel.  On the other hand, high-glycemic foods (especially processed carbohydrates) spike insulin levels, raise blood sugar, and send a double wammy message to your body telling it to (1) store calories as fat and (2)block body fat from being used as fuel.  The CrossFit prescription is a low-glycemic diet and consequently severely blunts the insulin response.

Caloric Restriction and Longevity
Current research strongly supports the link between caloric restriction and an increased life expectancy. The incidence of cancers and heart disease sharply decline with a diet that is carefully limited in controlling caloric intake.  The CrossFit prescription is consistent with this research.  The CrossFit prescription allows a reduced caloric intake and yet still provides ample nutrition for rigorous activity

Some interesting facts:

How many Americans suffer from Type 1 and Type 2 Diabetes?

Nearly 21 million Americans have diabetes, a group of serious diseases characterized by high blood glucose levels that result from defects in the body’s ability to produce and/or use insulin. Diabetes can lead to severely debilitating or fatal complications, such as heart disease, blindness, kidney disease, and amputations. It is the sixth leading cause of death in the United States. Type 2 diabetes, which accounts for 90% to 95% of all diagnosed cases of diabetes, involves insulin resistance – the body’s inability to properly use its own insulin. Type 2 used to occur mainly in adults who were overweight and ages 40 and older. Now, as more children and adolescents in the United States become overweight and inactive, type 2 diabetes is occurring more often in young people. (CDC)

How many American’s have cancer?

In 2005 over 10 million American’s were diagnosed with cancer (Cancer.Org) and 1,372,910 new cases diagnosed every year.

What is the leading killer of Americans?

Cancer is responsible for 570,280 deaths.

How many Americans are obese?

Obesity is out of control in the United States: 3.8 million people are over 300 pounds, over 400,000 people (mostly males) carry over 400 pounds and the average adult female weighs an unprecedented 163 pounds.

  • Between 1962 and the year 2000, the number of obese Americans grew from 13% to an alarming 31% of the population.
  • 63% of Americans are overweight with a Body Mass Index (BMI) in excess of 25.0.
  • 31% are obese with a BMI in excess of 30.0.
  • Childhood obesity in the United States has more than tripled in the past two decades.
  • According to the U.S. Surgeon General report obesity is responsible for 300,000 deaths every year.

Overweight and obesity are known risk factors for:

  • diabetes
  • coronary heart disease
  • high blood cholesterol
  • stroke
  • hypertension
  • gallbladder disease
  • osteoarthritis (degeneration of cartilage and bone of joints)
  • sleep apnea and other breathing problems
  • some forms of cancer (breast, colorectal, endometrial, and kidney)

Obesity is also associated with:

  • complications of pregnancy
  • menstrual irregularities
  • hirsutism (presence of excess body and facial hair)
  • stress incontinence (urine leakage caused by weak pelvic floor muscles)
  • psychological disorders, such as depression
  • increased surgical risk
  • increased mortality

Official Fish Oil (Omega-3) FAQ’s
Looking for the fish oil calculator? You don’t need it any longer, as we’ve greatly simplified things for you. (You’re welcome.) Refer to our general dose recommendations below.

Read the Official Fish Oil (Omega-3) FAQ’s

Q:  Where do Omega-3 fatty acids come from?A:  Omega-3 fatty acids are found in the green leaves of plants, like grass, phytoplankton, algae and seaweed. This is the food that OUR food is designed to eat, which makes grass-fed beef, pastured organic eggs, and most importantly, certain types of fish (wild-caught fish and fish lower on the food chain, like herring, anchovy, sardine and mackerel) are good, natural sources of omega-3′s.  Unfortunately, due to poor meat quality, and over-consumption of fast foods, processed foods, and vegetable oils, most of our diets are lacking in these essential fatty acids (and overly rich in pro-inflammatory omega-6 fatty acids).

Q:  So why can’t I just eat grass or seaweed to get my omega-3′s?

A:  First, you don’t have the ability to digest grass properly.  Moving on, omega-3′s are a family of fatty acids, and the “parent” molecule is called alpha-linolenic acid (abbreviated as LNA or ALA). The ALA from plants is converted by animals or fish to the potent anti-inflammatory omega-3′s called EPA and DHA by a long conversion process (see the discussion of ALA from plant seeds below). The ALA itself is not actually anti-inflammatory, and only a small percentage of ALA can be converted to EPA and DHA. Fish (and to a much lesser degree, land animals) do the metabolic work to convert the plant-based ALA into concentrated EPA and DHA.  Fish oil is already a concentrated source of EPA and DHA, which is why fish oil has such potent anti-inflammatory properties.

Q:  Why can’t I get my omega-3′s from flax?

A:  There are countless problems with getting your omega-3′s from this particular plant source. It requires an extremely inefficient conversion process – meaning your body has to do a lot of work to get the EPA and DHA you want out of the kind of fat found in flax (ALA). And the conversion pathway is fraught with difficulties that can, in fact, lead to MORE inflammation – the exact opposite of the intention. Finally, even if everything works perfectly, the amount of EPA and DHA you can actually convert from flax is so small it practically doesn’t count.  (By the way, the story is the same whether you’re talking about flax, chia, hemp or echium.)  Just stick with your fish oil.

Q:  Why do I need EPA and DHA?

A:   You only need a quick web search for this one, because there is a wealth of information on this subject.  Fish oil is not a magic bullet, but there are an infinite number of well-documented benefits for a whole host of lifestyle diseases and conditions.  The short answer is that EPA and DHA are specific types of polyunsatured omega-3 fatty acids.  Your body cannot produce these fatty acids – you must get them from the food you eat, or via supplementation.  EPA and DHA are natural anti-inflammatory agents, and as such, play a role in brain health, heart health, protection against cancer, Alzheimer’s and depression, improvement of skin conditions like psoriasis and acne, fetal brain development, inflammatory bowel disorders, and arthritis, to name a few.

Our typical diets are rich in another type of pro-inflammatory polyunsaturated fatty acid called omega-6.  When our dietary intake of omega-6′s far exceeds our intake of omega-3′s, our bodies experience a wide range of negative consequences, all with the underlying cause of increased systemic inflammation.  Minimizing dietary intake of omega-6 fatty acids, and supplementing your intake of omega-3 fatty acids, helps to reduce inflammation, and the wide range of downstream effects.

Q:  Is there an ideal EPA to DHA ratio?

A:  This isn’t particularly important – but a supplement in the general neighborhood of 1:1 would be a good find. DHA converts to EPA easier than vice versa, so if you had to choose, choose a high-DHA oil.

Q:  What else should I look for in a fish oil brand?

A:  First and most importantly, squeaky clean ingredients.  This means your fish oil should be free of soy (including lecithin), dairy, wheat, rice, sweeteners or other artificial ingredients.  (Visit our Supplement Evaluation Checklist for more information.)

Then, look at the EPA and DHA amounts per serving – that’s far more important than the “total fish oil” amount.  A concentrated source means you have to take fewer pills or teaspoons a day – it’s more efficient, and makes it more likely that you’ll actually take your recommended dose each day.

Finally, decide whether you want a liquid or capsule.  We prefer liquid, because liquid forms are often more concentrated than pills, and don’t have the additional ingredients found in capsules or pills with enteric coating.  (Some find the coating on fish oil pills irritating, even allergenic.)

Q:  What fish oil brands does Whole9 recommend?

A: The brand we take personally is Stronger Faster Healthier’s OmegaMaine.  We’ve tried lots of other brands, and like quite a few (including Carlson’s and Nordic Naturals), but we choose OmegaMaine for three reasons.

-First, the ingredients are squeaky clean – no soy, dairy, wheat, sweeteners or other artificial ingredients.

-Second, it has more EPA and DHA per teaspoon (1.8 grams!) than other high quality brands, and taking in a bunch of fragile PUFAs besides EPA and DHA isn’t a great idea. Prioritize the EPA and DHA, and minimize your PUFA intake in general.

-Third, it comes in five palatable flavors (lemon, tangerine, mint, chocolate and vanilla), and all taste pretty darn good… for fish oil.

Q:  Does liquid fish oil taste like fish?

A: Depends on the brand, but not usually.  Most liquids come flavored (lemon and tangerine are popular), and though they’re definitely oily, most don’t leave a fishy aftertaste.  If you’re having trouble taking a shot of oil, try this tip – “chase” your oil with a bite of fruit, like a raspberry or a grape.  The tartness of the fruit tends to cut through the oil in your mouth.

Q:  Do I have to be worried about mercury levels or other contaminants in fish oil?

A:  In a word, no.  The larger the fish, and the higher it is on the food chain, the more potential exposure it has to heavy metals and other contaminants.  Fish oil is almost always harvested from small fish like herring, anchovy and sardines, all of which are very low on the food chain.  Most high quality fish oil brands are tested to ensure that any mercury or other heavy metal levels are all below detectable levels (.01ppm).  In addition, a 2006 ConsumerLab evaluation of 42 commercially available fish oil supplements found that all were free of mercury, PCBs and dioxins.

Q:  Are there any contraindications for taking fish oil?

A:  Because fish oil capsules have an effect on reducing the stickiness of platelets, it is recommended that if you have any of the following conditions, that you see your physician to discuss whether you should take fish oil capsules:

-You have a bleeding tendency

-You are on blood thinning medications

-You are about to have surgery

Of course, before starting any new medication or supplement, it is always a smart idea to consult your physician, right?

Q:   I’m pregnant – is it safe to take fish oil?

A:  First, consult your doctor before starting any medications or supplementation.  The general consensus is that EPA, and especially DHA, provide excellent benefits for your baby’s neurological and early visual development, and may reduce the risk of pregnancy complications like pre-eclampsia, gestational diabetes, post-partum depression and pre-term delivery.  Your recommended dose will be different, however… again, check with your doctor to find a range that’s healthy for you and your baby.

Q:   How much fish oil should I take?

A:  Our general recommendations are to aim for around 2-4 grams of EPA/DHA per day.  However, if you eat lots of wild-caught salmon, grass-fed beef and other natural sources of omega-3 fatty acids, and generally avoid sources of omega-6 (like vegetable oils, factory-farmed meat, nuts and seeds), you may not need any fish oil supplementation at all.

Q:  I’m pretty inflamed/sick/overweight.  Can I take more than you recommend to jump-start results?

A:  Hear us clearly – you can’t fish oil your way out of poor dietary choices, lack of sleep, over-training or any combination of the above. It’s of the utmost important that you get your dietary and lifestyle house in order!   More fish oil is not better – and in some instances, can do more harm than good.  So make better food choices, get to bed earlier, allow yourself more time to rest and recover and do your best to minimize stress – and don’t rely on any pill or supplement to fix your stuff.

Q:   How do I take fish oil?

A:  Most importantly, always take fish oil with meals.  This reduces the chance of stomach upset or “fish burps”.  We think about sandwiching our fish oil inside a meal – one bite of food, then our fish oil, followed by the rest of our meal.  And split your dose up throughout the day, especially if you’re at a 0.5 factor or above.   Finally, if you’re new to fish oil, ramp up to your recommended dose slowly.

Q:   What happens if I take too much fish oil?

A:  Your digestive tract will tell you – and things will “move along” far too quickly for comfort.  We can’t imagine the moderate doses we recommend (no more than 4 grams of EPA/DHA per day) would cause digestive upset, however… unless your fish oil was of poor quality, with a low concentration of EPA/DHA.  (Yet another reason to stick with a high quality, highly concentrated brand.)

Q:  How do I store fish oil?

A:  Keep fish oil in a cool, dark place.  Your refrigerator is the ideal location, especially in summer.  If your pills don’t have a dark capsule coating and/or come in a light colored bottle, this is especially important.  Fish oil reacts to light and heat, and can turn rancid.  Rancid fish oil – obvious based on the smell – should be immediately discarded.

Q:  Do I count my fish oil as calories or fat grams?

A:  First, why on earth are you counting calories?  While different folks have different answers for this question, we say no.  The way your body uses EPA and DHA is different than other types of fat – the eicosanoid biosynthetic pathway, the brain, and the retina have first dibs, and EPA and DHA are typically used in these pathways as opposed to being used as “fuel”.

Q:  What about krill oil?

A:  While some folks make grand claims about krill oil, we think it’s way too expensive, and isn’t a very concentrated source of EPA and DHA, and so just isn’t worth the additional cost. Stick with your fish oil.

Q:  What about cod liver oil?  I heard it’s a good source of fish oil PLUS vitamins A and D.

A:  There have been some concerns about the level of vitamins A and D in cod liver oil.  The excessively high levels of vitamin A can prove toxic at the levels our calculator recommends for your ideal EPA/DHA dose.  In addition, the amount of vitamin D in cod liver oil are pretty low – meaning you’re not really getting a good boost of D.  Plus there are some smart folks who believe that high levels of vitamin A will limit the effectiveness of vitamin D, which could potentially lead to a D deficiency. We sometimes take CLO, but only at smaller doses (i.e. our maintenance dose)

In summary, if you want to stick with the cod liver oil, do NOT use our Fish Oil Calculator for your dosage recommendations. A better choice, in our opinion, would be to stick with fish oil.

Q:  I’m a vegetarian/vegan – are there any plant-based alternatives to fish oil?

A:  Algae oil is the best alternative, although it’s nowhere near as effective or cost-efficient as fish oil.  Most algae oil contains only DHA, and you’ll find even those that contain some EPA will have an extremely low concentration per pill. It’ll cost you an arm and a leg, but it’ll do the trick.
