What percentage of total daily calories should come from protein sources?

The recommendation for protein intake in relation to total daily calories suggests that 12-15% of those calories should ideally come from protein sources. This percentage is consistent with dietary guidelines issued for individuals engaging in moderate physical activity, where an adequate protein intake is necessary to support muscle repair, maintenance, and overall bodily functions.

Protein plays a key role in numerous physiological processes, including the development and repair of tissue, hormone production, and immune function. By ensuring that protein constitutes this percentage of caloric intake, individuals can meet their nutritional needs while maintaining overall health and wellness.

While higher percentages of protein intake can be beneficial for certain populations, such as athletes or those working to gain muscle mass, the 12-15% range represents a balanced approach for the general population. This range allows one to benefit from the macronutrient while still providing the necessary fats and carbohydrates for energy and overall health.
