Paleo Lifestyle Rules - How it Works, What to Eat and the Risks


The Paleo Lifestyle Rules

The Paleolithic diet is one of the most popular alternative eating styles practiced today. Its popularity can be attributed to its simplicity and the interesting theory behind its rules.

In this blog, you'll come to understand the essential rules of the Paleo lifestyle, including the reasoning behind the diet and the foods you can or can't eat on it.

What is Paleo?

The Paleo lifestyle is based on the diets of our ancestors in the Paleolithic era, which lasted from 2.5 million years ago to 10,000 years ago. This is why one might hear Paleo referred to as the "Caveman diet."

During this period, humanity fed itself primarily through hunting and gathering, and thus our diets consisted mostly of vegetables, fruits, wild-caught meats, and nuts & seeds. You might notice this is similar to other healthy diets, like the Mediterranean diet.

What Paleolithic humans did not eat was anything processed, including bread, pasta, dairy, or other items common to our contemporary diets.


Fruits and vegetables

The Paleo lifestyle hypothesis

The Paleo lifestyle postulates that our bodies are evolved to metabolize hunter-gatherer foods, but are ill-equipped to handle processed foods.

Unlike some diets that focus on nutritional features of food, like what is keto diet friendly, the focus is much more on where food comes from and how its grown. This makes paleo perfect for people interested in the environmental impact of their food.

Since they're easy to make a lot of, processed foods have become abundant in our society (to the detriment of our health).

While scientific evidence suggests the problem isn't quite so simple as that, it's plainly true that refined sugar, cheap carbohydrates, and high levels of sodium have contributed to the health crises we currently face.

This hypothesis poses a complicated question with no easy answer, but studies have suggested that Paleolithic nutrition has definite advantages.

The health benefits

By removing processed carbs, sugars, and unhealthy fats, the paleo lifestyle can help you lose weight, control your blood pressure, and better manage your glucose levels.

Obesity-related health risks, like heart disease and metabolic syndrome-related NAFLD, have also been mitigated using a paleo lifestyle.

For some, the simplicity of the diet is also a positive factor.

A list of Paleo lifestyle foods

To give you an idea of what is paleo lifestyle approved, here's a list of nutritious, delicious, and versatile foods that we've been eating since we lived in caves -

  • Meat - beef, lamb, turkey, chicken, pork, etc.
  • Fish/seafood - trout, salmon, haddock, shrimp, shellfish, etc.
  • Eggs - choose free-range or pasture-raised
  • Vegetables - broccoli, kale, asparagus, onions, carrots, spinach, etc.
  • Fruits - apples, bananas, berries, oranges, avocados, tomatoes, etc.
  • Tubers - potatoes, yams, sweet potatoes, turnips, etc.
  • Nuts and seeds - almonds, cashews, macadamias, hazelnuts, sunflower seeds, pumpkin seeds, etc.
  • Healthy fats and oils - extra-virgin olive oil, avocado oil, coconut oil
  • Spices - sea salt, turmeric, garlic, rosemary, thyme, etc.

That's a lot, right? What's appealing about the paleo lifestyle is that it isn't as exclusive as other trendy diets. The real secret is in finding good quality ingredients and preparing them without processed additives.

Let's address the foods you'll avoid on a paleo lifestyle, and you'll see that entire food groups usually included in clinical nutrition are excluded from this "Stone-Age" diet.

Foods to avoid on a Paleo lifestyle

Here are some of the foods that one cannot eat on a paleo lifestyle  -

  • Sugar and high-fructose corn syrup - soft drinks, juices, cane sugar, pastries, candy, ice cream, etc.
  • Grains - bread, pasta (wheat, spelt, rye, barley, etc.)
  • Legumes - peanuts, beans, lentils, etc.
  • Dairy - *some versions of paleo allow for full-fat products like butter and cheese, but most dairy products are not allowed on a strict paleo lifestyle meal plan
  • Some vegetable oils - sunflower oil, soybean oil, cottonseed oil, and others
  • Trans fats - found in margarine, these are known as "hydrogenated oils." Steer clear.
  • Artificial sweeteners - aspartame, sucralose, etc. Use natural sweeteners instead, like monkfruit.

Who benefits from the Paleo lifestyle?

In its essence, a core of vegetables and healthy fats with grass-fed meat and seafood, the Paleo lifestyle (or at least some Paleo meals) could benefit most anyone. It's whole foods prepared simply.

The primary reason people follow a Paleo lifestyle is for the health benefits associated with eliminating processed food.

Cutting carbohydrates, refined sugar, and many additives now at play in our diets, has clear associations with improved health. Paleo is commonly used for weight loss.

It's worth noting that there is no scientific consensus on the Paleo lifestyle. While studies have demonstrated that a Paleo lifestyle can lead to certainly improved health markers, there is no conclusive evidence that cutting all grains and dairy is necessarily the determining factor - nor is there proof that Paleolithic humans ate only the foods recommended in the diet typically. The evolution of human nutrition is a long and complex story, and we don't have all the answers.

The reported benefits of a Paleo lifestyle include -

  • improved cholesterol
  • reduced blood pressure
  • improved glycemic control
  • reduced waist circumference and weight loss
  • improved satiety
  • improved gut health
  • reduced all-cause mortality
  • mitigation of metabolic syndrome
  • reduced risk of cardiovascular disease

What are the disadvantages of the Paleo lifestyle?

Not all nutritional experts agree on Paleo, however.

By removing all grains from the diet, the dieter will consume less fiber compared to clinical nutrition. By removing all dairy products, the dieter may consume less calcium and vitamin D than recommended.

This study found that following the Paleo lifestyle increased the levels of a chemical in the gut which has been tied to heart disease. Meat-heavy Paleo lifestyle contain too much saturated fat, which can have serious negative health effects long-term.

Can you eat cheese on Paleo?

A Paleo-diet purist will tell you no, all cheese should be avoided on a Paleo lifestyle. Paleolithic humans didn't milk cows or process dairy. This is one case in which keto diet rules are much more lax than paleo.

Some Paleo lifestyle followers reintroduce some cheese and dairy, often full-fat and from raw (unpasteurized) milk.

Ultimately, the Paleo lifestyle encourages us to consume dairy only after due consideration and not as part of the habits that define the typical contemporary diet.

Banana and coffe

Can I eat bananas on the Paleo lifestyle?

As with all fruits and vegetables, bananas are Paleo-approved. Interestingly, however, the modern banana did not exist until recently and was created through deliberate breeding in order to produce sweeter fruit.

Is coffee Paleo-friendly?

Most Paleo lifestyle followers will tell you no, coffee is not Paleo, as the techniques for roasting and brewing coffee only arose around the Fifteenth Century CE. However, being so widely popular, coffee is something that many Paleo lifestyle followers make an exception for. The negative side-effects of coffee are well known: consider alternatives like teas or non-caffeinated energizing beverages.

Do doctors recommend the Paleo lifestyle?

While it's impossible to generalize doctors' opinions on Paleo, this much can be said: a healthy eating plan based on consuming lots of vegetables, healthy fats, fruits, and lean meats is widely accepted as a good idea for most people.

If you're wondering if a Paleo lifestyle or something similar could be right for you, consult your healthcare provider or registered dietician.
