What is a common consequence of high-protein diets if not consumed with other food groups?

High-protein diets can lead to nutritional deficiencies when consumed without a balance of other food groups. Although proteins are essential for numerous bodily functions, including muscle repair and immune function, they do not provide all the necessary vitamins, minerals, and fibers that other food groups like fruits, vegetables, and whole grains offer. A diet excessively focused on protein may result in a lack of essential nutrients such as vitamins A and C, calcium, and dietary fiber, which are important for overall health and well-being.

While weight loss can happen on a high-protein diet due to satiety and caloric restriction, it is not a direct consequence of the diet itself. Similarly, increased hydration is not inherently linked to high-protein consumption unless water intake is deliberately increased to manage the stress on the kidneys from protein metabolism. Enhanced muscle recovery may occur with proteins, but it must be accompanied by carbohydrates and other nutrients to provide the balanced support needed for optimal recovery. Thus, the most significant and common consequence of focusing solely on a high-protein diet is the potential for nutritional deficiencies.
