What percentage of total calories should come from proteins?

The recommendation for protein intake typically suggests that 15-20% of total daily caloric intake should come from protein sources. This range supports various physiological functions, including muscle repair, hormone production, and immune function. Adequate protein is essential, especially for individuals who engage in physical training or have higher physical demands, as it helps maintain muscle mass and supports recovery processes.

Consuming protein within this range is particularly important for athletes, as it can enhance performance and recovery. The body uses amino acids derived from proteins to build and repair tissues, which is crucial after exercise. Therefore, maintaining an intake of 15-20% from protein ensures that individuals meet their bodily needs without exceeding caloric demands that can lead to weight gain or imbalances in nutrient intake. Overall, this percentage is well-aligned with guidelines from various health organizations promoting balanced nutrition for overall health and performance.
