The recommended percentage of total daily calories that should come from protein is typically set at 10%-35%. This range is supported by various nutritional guidelines, including those from the Dietary Guidelines for Americans and the Acceptable Macronutrient Distribution Ranges (AMDR).

Protein is essential for a variety of bodily functions, including muscle repair, production of enzymes and hormones, and maintaining overall cellular health. The middle point of this range, around 15%-20%, is commonly suggested for those engaging in regular physical activity. Athletes or individuals aiming to build muscle may benefit from protein intake on the higher end of the spectrum.

This range ensures that individuals can consume adequate protein to meet their physiological needs while also allowing room for the recommended intake of carbohydrates and fats, which are also important for overall health and energy balance. Consuming protein within this recommended percentage helps individuals maintain proper body function and can support training outcomes.
