The Paleo Diet Is Universally Optimal for Everyone

  Paleo diet and individual differences

Paleo advocates often tout the diet as the ultimate fix for all dietary woes—a one-size-fits-all solution that promises weight loss, improved energy, and freedom from chronic illness. But does this prehistoric meal plan really work for everyone? Or is it more like trying to wear someone else’s loincloth—awkward and maybe not the best fit?

The Claim: Paleo Works for Everyone

The Paleo diet promotes itself as a universal solution, arguing that since it’s rooted in the eating habits of our shared ancestors, it’s ideal for all humans. The pitch is simple: cut out processed foods, grains, legumes, and dairy, and your body will thank you with boundless health.

The Reality: Humans Are Diverse

While the Paleo diet can work wonders for some people, the idea that it’s universally optimal ignores the complexity of human biology, lifestyles, and preferences. Here’s why one size doesn’t fit all:

  • Genetic Variability: Humans are incredibly diverse, and our dietary needs often depend on genetics. For example:
    • Some people thrive on high-carb diets (think rice-heavy cuisines in Asia), while others do better with more fat or protein.
    • Lactase persistence allows many people to digest dairy without issue, making it a valuable source of nutrition.
  • Health Conditions: People with specific health conditions might not find Paleo beneficial—or practical. For example:
    • Those with kidney issues may struggle with the diet’s high protein intake.
    • Athletes requiring high-energy carbs for endurance might find Paleo’s carb restrictions limiting.
  • Lifestyle Differences: The Paleo diet assumes that everyone has access to fresh, unprocessed foods, which is only valid for some people. Time, budget, and food availability play significant roles in diet success.
  • Cultural and Personal Preferences: Food is about more than just fuel—it’s culture, comfort, and connection. For many, cutting out grains, legumes, or dairy would mean sacrificing staple foods that have been eaten for centuries without harm.

The Problem with the Claim

No diet works perfectly for everyone. Presenting Paleo as the universal solution risks alienating those for whom it doesn’t fit. People need flexibility in their diets, not rigid rules based on a romanticised version of history.

Why This Myth Persists

The simplicity of Paleo is appealing. Its “back-to-basics” message resonates with people frustrated by modern processed foods, and it’s easy to market as a cure-all. However, nutrition is rarely that simple, and what works for one person might not work for another.

The Takeaway

The Paleo diet can be an excellent choice for some, but more is needed. Our bodies, lifestyles, and cultural food traditions are far too varied for a one-size-fits-all approach. Instead of unquestioningly adopting someone else’s caveman diet, find what works for your body—and if that includes grains or dairy, your inner caveman won’t mind. After all, they were too busy surviving to worry about what was on someone else’s plate.
