What is one of the major downsides of the Paleo diet?

One of the major downsides of the Paleo diet is that it is based heavily on animal sources, which can lead to various nutritional and health concerns. By relying on more than 50 percent of daily calories from animal products, individuals following this diet may consume excessive amounts of saturated fats and cholesterol. This has the potential to influence heart health negatively and exacerbate conditions such as cardiovascular disease. Furthermore, a diet high in animal protein can create imbalances in nutrient intake, as it tends to limit the variety of foods consumed.

While some people may thrive on a Paleo diet, concerns about the environmental impact of consuming a large quantity of animal products, such as greenhouse gas emissions and resource use, are also relevant considerations. Additionally, the restrictive nature of this diet may lead to difficulty in maintaining balanced nutrition, as individuals might miss out on important nutrients found in plant-based foods.
