Paleo is the Scientology of diets — and I say that with full awareness of how provocative it sounds. Both have a charismatic origin story, a devoted following, a tendency to dismiss outside science, and a commercial apparatus built around belief. That doesn’t mean paleo is worthless. But it does mean you should think critically before buying in.
What Is the Paleo Diet?
The paleo diet — short for Paleolithic — is based on the idea that humans should eat like our Stone Age ancestors: meat, fish, vegetables, fruits, nuts, and seeds. It eliminates grains, legumes, dairy, refined sugar, and processed foods. The premise is that our bodies are genetically mismatched to modern agricultural foods, and reverting to ancestral eating patterns will optimize health.
Where Paleo Gets It Right
Let’s be fair. Paleo does several things well. Eliminating processed junk food, refined sugar, and refined carbohydrates is objectively good advice. Emphasizing whole foods, vegetables, lean meats, and healthy fats is solid nutritional practice. Many people lose weight and feel better on paleo — not because of ancestral alignment, but because they’ve dramatically cut caloric density and improved food quality.
Where Paleo Goes Off the Rails
The problem isn’t what paleo removes — it’s the mythology surrounding why. The “ancestral mismatch” hypothesis is not well-supported by evolutionary science. Our Paleolithic ancestors ate wildly different diets depending on geography. Many traditional cultures thrive on grains and legumes. The idea that there’s one optimal “ancestral diet” is a convenient story, not a scientific conclusion.
The blanket elimination of legumes and whole grains is also not evidence-based. Both have decades of research showing positive associations with health, longevity, and reduced disease risk. Tossing out lentils and oats because a caveman didn’t have them ignores that humans have been eating them successfully for thousands of years.
The Cult Dynamics
What makes paleo resemble Scientology isn’t its dietary recommendations — it’s the social structure around it. True believers who dismiss contrary evidence. Influential figures building supplement and book empires off the ideology. A tendency to attribute any health problem to “not being paleo enough.” Online communities that treat deviation as heresy. This tribal certainty about nutritional science — a field filled with genuine uncertainty — should give anyone pause.
What the Science Actually Says
Research on paleo diets shows short-term benefits for weight loss and metabolic markers — comparable to other dietary interventions like Mediterranean or low-carb diets. Long-term data is sparse. The benefits that appear are likely attributable to caloric reduction and improved food quality, not anything unique to the paleo framework. No randomized controlled trial has demonstrated that eliminating legumes or grains produces superior long-term health outcomes.
The Pragmatic Takeaway
If paleo works for you — if it gets you eating more vegetables, fewer processed foods, and keeps you consistent — use it as a framework. But hold it loosely. The dogma is the danger, not the diet. Eat mostly whole foods, prioritize protein, control your calories, and don’t let anyone tell you that a bowl of lentil soup is destroying your health. Paleo is a useful heuristic dressed up in pseudoscientific mythology. Use the heuristic. Ditch the mythology.
What This Means for Getting Six Pack Abs
For six pack abs specifically, the diet framework matters far less than adherence to a caloric deficit with high protein. Whether you’re eating paleo, Mediterranean, or flexible dieting — the results are driven by energy balance and protein intake. A paleo approach can absolutely support a six pack. So can a non-paleo approach. What kills results is following any diet so rigidly that you can’t sustain it.
