Key Takeaways
The paleolithic diet, also known as the ancestral diet, is a nutritional approach based on foods available in prehistoric times. Despite growing popularity, its use in sports generates both enthusiasm and skepticism. This article aims to provide a comprehensive evaluation of the benefits and potential drawbacks of the paleolithic diet in the context of physical activity.

Foundations and Philosophy of the Paleo Diet
First of all, it should be noted that the food available thousands of years ago was far more natural and less modified than it is today, which is why the way our ancestors ate fundamentally differed from the diet of modern humans. Our ancestors were physically robust and largely free from modern civilization diseases. The physical activity of hunter-gatherer populations was exceptionally high, driven by their active lifestyle. Attempting to replicate the menu of our paleolithic ancestors aims to improve well-being, physical appearance, overall health, and reduce the risk of various diseases. Physiologically, we do not differ significantly from our predecessors. The primary assumptions of the paleo diet involve the elimination of foods rich in salt, refined sugars, and trans fats found in ultra-processed foods. Furthermore, this nutritional framework requires the complete exclusion of all grains, legumes, potatoes, as well as dairy products. The fundamental diet of our ancestors consisted primarily of wild game meat, plant roots, fruits, fish, eggs, nuts, and a small amount of honey.
The Paleo Diet in Athletic Nutrition – Benefits
There is no doubt that the main advantage of the paleo diet is the exclusion of foods rich in refined sugars, hydrogenated fats, and empty calories. The mere elimination of highly processed foods contributes significantly to improving health. Nevertheless, the regular consumption of nutrient-dense products such as game meat, eggs, fish, fruits, vegetables, and nuts can have a beneficial effect on overall metabolic health, physical fitness, and body composition. The ancestral diet, which involves a significant reduction in carbohydrate intake, appears particularly noteworthy for individuals struggling with obesity, lipid disorders, and insulin resistance. However, it must be emphasized that any diet should be individually tailored to the physiological needs of the organism, and in the case of medical conditions, consultation with a physician and an experienced dietitian is essential.
Potential Risks and Disadvantages in Sports
Long-term adherence to a low-carbohydrate diet without accounting for periodic carbohydrate loads can lead to a decrease in thyroid hormone levels, particularly affecting the conversion of T4 to T3. Such nutritional strategies may also suppress leptin release and increase the concentration of sex hormone-binding globulin (SHBG) in the blood, thereby lowering free, biologically active testosterone levels. For individuals aiming to efficiently build muscle mass, and those with high energy demands, the diet must be thoughtfully supplemented with adequate glucose sources. Ultimately, there are many variations of the paleo diet rather than a single strict menu. For practitioners, selecting high-quality organic and grass-fed products remains the best approach.
