The paleo diet is a dietary approach that emphasizes whole foods that were commonly eaten during the Paleolithic era, which dates back 2.5 million to 10,000 years ago.

It is also known as the caveman diet, Stone Age diet, hunter-gatherer diet, or ancestral diet. The rationale is that our genes have not had enough time to adapt to modern foods that are high in refined carbohydrates, trans fats, and artificial ingredients, causing chronic diseases such as obesity, diabetes, heart disease, and cancer.

What to Eat on the Paleo Diet

The paleo diet is based on the principle of eating real, nutrient-dense, and minimally processed foods that do not cause spikes in blood sugar and insulin levels. Here are some examples of foods that are allowed:.

Meat: beef, pork, lamb, chicken, turkey, bison, game meat, organ meats, and bone broth.
Fish and seafood: salmon, tuna, trout, mackerel, oysters, clams, shrimp, and crab.
Eggs: preferably from free-range or pasture-raised chickens.
Vegetables: all kinds of non-starchy vegetables, such as leafy greens, broccoli, cauliflower, carrots, peppers, onions, garlic, and mushrooms.
Fruits: in moderation, such as berries, apples, pears, oranges, bananas, and mangoes.
Nuts and seeds: almonds, walnuts, pecans, macadamia nuts, hazelnuts, pistachios, pumpkin seeds, sesame seeds, and sunflower seeds.
Fats and oils: coconut oil, olive oil, avocado oil, ghee, and lard.

What to Avoid on the Paleo Diet

The paleo diet excludes foods that were not available during the Paleolithic era or that have been processed in ways that compromise their nutritional value. Here are some examples of foods that are not allowed:.

Grains: wheat, barley, oats, corn, rice, and quinoa.
Legumes: beans, peas, lentils, soybeans, and peanuts.
Dairy: milk, cheese, yogurt, and butter.
Refined sugar: table sugar, high-fructose corn syrup, and artificial sweeteners.
Processed foods: anything that comes in a package or a can and has a long list of ingredients.
Industrial oils: soybean oil, corn oil, cottonseed oil, and canola oil.

Benefits of the Paleo Diet

The paleo diet has been associated with several health benefits, although more research is needed to confirm them. Here are some of the potential advantages:.

Weight loss: The paleo diet is inherently low in calories and high in protein and fiber, which can help reduce body fat and improve satiety.
Blood sugar control: The paleo diet eliminates refined carbohydrates and sugar, which are major contributors to insulin resistance and type 2 diabetes.
Inflammation reduction: The paleo diet emphasizes anti-inflammatory foods that are rich in antioxidants, vitamins, and minerals, such as vegetables, fruits, nuts, and fish.
Gut health improvement: The paleo diet supports a healthy gut microbiome by avoiding foods that can disrupt it, such as grains, legumes, and dairy, and promoting foods that are prebiotic or probiotic, such as fermented vegetables and bone broth.
Heart health enhancement: The paleo diet reduces the risk factors for heart disease, such as high blood pressure, high cholesterol, and inflammation, by emphasizing healthy fats, lean proteins, and fiber, and minimizing processed and refined foods.

Potential Drawbacks of the Paleo Diet

The paleo diet may not be suitable for everyone, especially those who have certain health conditions or dietary preferences. Here are some of the possible concerns:.

Nutrient deficiencies: The paleo diet eliminates some foods that are good sources of essential nutrients, such as calcium from dairy, iron from legumes, and folate from grains, so careful planning is required to ensure adequate intakes.
Cost and availability: The paleo diet can be more expensive and less convenient than a typical Western diet, as it requires fresh, organic, and grass-fed foods, which may not be affordable or accessible to everyone.
Social isolation: The paleo diet may limit social occasions that involve eating out or sharing meals with friends and family who do not follow the same dietary preferences.
Environmental impact: The paleo diet may have a higher environmental footprint than a plant-based diet, as it relies on animal products that have a larger carbon footprint, cause deforestation, and contribute to climate change.
Eating disorders: The paleo diet may trigger or exacerbate disordered eating habits, such as orthorexia, which is an obsession with healthy eating that can lead to malnutrition, anxiety, and social isolation.

Paleo Diet for Athletes

The paleo diet has gained popularity among athletes who seek to optimize their performance, recovery, and health.

However, the paleo diet may not provide enough carbohydrates, which are the main fuel for high-intensity exercise and glycogen replenishment. Therefore, athletes who follow the paleo diet may need to modify it by including starchy vegetables, fruits, and tubers, or by using targeted carbohydrates around workouts.
