What might be a nutritional concern for someone on a high-protein diet?

A high-protein diet can lead to several nutritional concerns, and one of the most significant is the potential for chronic disease. Consuming excessive amounts of protein, particularly from animal sources, can increase the intake of saturated fats and cholesterol, which are associated with a higher risk of cardiovascular disease. Furthermore, when protein intake exceeds the body’s needs, it may lead to kidney damage over time due to increased nitrogen waste that the kidneys must filter. This concern is particularly pronounced in individuals with pre-existing kidney conditions.

While increased fiber intake and lower energy levels could occur in some scenarios related to dietary shifts, these are not inherent to a high-protein diet itself. Decreased metabolism is also less likely, as a higher protein intake can actually support metabolism through the thermic effect of food, where digesting protein requires more energy than fats or carbohydrates. Thus, the potential for chronic disease stands out as a critical consideration for individuals following a high-protein diet.
