The recommended percentage of protein in a balanced diet is typically around 20% to 30%. Selecting a value of 30% aligns with many nutritional guidelines that suggest protein should comprise a significant portion of macronutrients. The rationale behind this recommendation is that protein plays a crucial role in building and repairing tissues, producing enzymes and hormones, and supporting overall bodily functions.

A balanced intake of protein, particularly in the context of active individuals or those participating in strength training, contributes to muscle preservation and growth. Additionally, protein can aid in satiety, helping to manage appetite. While different dietary patterns may adjust the exact percentage based on individual needs, 30% is a reasonable guideline for individuals looking to maintain a balanced and healthful diet.

Calculating macronutrient needs often involves considering energy expenditure, activity level, and specific goals (such as fat loss or muscle gain), and this can influence how one might approach their protein intake accordingly. The other percentages offered would either over-restrict protein or place it at a less optimal level for maintaining muscle mass and overall health.
