A high-protein diet may present several potential risks, including kidney strain, especially for individuals with preexisting kidney conditions. Excessive protein intake can lead to dehydration as the body requires more water to metabolize proteins. There is also a risk of nutrient imbalance if other essential food groups are neglected, which can lead to deficiencies in vitamins and minerals. Lastly, high-protein diets often associated with processed food can increase the risk of heart disease due to high saturated fat intake. Thus, moderation and a balanced approach are fundamental to overall health.
