What is the paleolithic diet?

The paleo diet is inspired by the presumed diet of our hunter-gatherer ancestors, before agriculture. It excludes grains, legumes, dairy, and processed foods. It focuses on meats, fish, vegetables, fruits, nuts, and seeds. The idea is that our genetics haven't had time to adapt to modern agricultural foods.

Allowed foods

Meats (preferably grass-fed), fish and seafood, eggs, vegetables (all except potatoes depending on version), fruits (in moderation), nuts and seeds, healthy oils (olive, coconut, avocado). Root vegetables like sweet potato are generally accepted.

Excluded foods

Grains (wheat, rice, corn, oats), legumes (beans, lentils, chickpeas), dairy products, refined sugars, processed vegetable oils (sunflower, soybean), ultra-processed foods. Salt and coffee are debated depending on the version.

What science says

Some studies show benefits of paleo on weight loss, blood sugar, and cardiovascular markers. However, excluding legumes and whole grains deprives of beneficial fiber and nutrients. The diet can be expensive and socially difficult to follow.

Important

Never go below 1200 kcal/day (women) or 1500 kcal/day (men) without medical supervision. Too aggressive a deficit can be dangerous for your health and counterproductive for weight loss.

Guide to the Paleolithic Diet

The paleo, or paleolithic, diet is inspired by what our ancestors supposedly ate before the advent of agriculture about 10,000 years ago. The hypothesis is that our bodies are better adapted to this type of eating.

Philosophy of the Paleo Diet

Paleo is based on the idea that:

  1. Our genetics haven’t evolved fast enough to adapt to modern foods
  2. Agriculture introduced foods we’re not adapted to
  3. Returning to “ancestral” eating would improve our health

Important note: This theory is scientifically debated. We don’t know exactly what our ancestors ate, and human evolution is more complex than suggested.

Potential Benefits

  1. Elimination of processed foods: beneficial for everyone
  2. High in protein and fiber: improved satiety
  3. Blood sugar stability: fewer insulin spikes
  4. Anti-inflammatory: elimination of refined oils

Criticisms and Limitations

  1. Exclusion of legumes: not scientifically justified
  2. High cost: quality meats, organic products
  3. Social difficulty: restaurants, family meals
  4. Risk of deficiencies: calcium (without dairy), fiber (without whole grains)
  5. Contested historical basis: our ancestors probably ate grains

Mistakes to Avoid

  1. Eating too much meat: hunter-gatherers ate lots of vegetables
  2. Ignoring calories: paleo can cause weight gain if caloric excess
  3. Strict version too long: legumes and whole grains are healthy
  4. Confusing “paleo” with “healthy”: paleo desserts can be very caloric
