What is the recommended macronutrient distribution for protein in daily calories?

The recommended macronutrient distribution for protein in daily calories is correctly identified as falling within the range of 10-35%. This wide range allows for individual variability based on several factors such as age, sex, physical activity level, and overall health goals.

Protein plays a crucial role in maintaining muscle mass, promoting recovery, and supporting overall metabolic functions, particularly during weight loss. Aiming for protein intake at 10% provides a baseline for individuals with lower activity levels or those following caloric restriction, while 35% could be beneficial for more active individuals or those focusing on muscle gain. This flexibility is essential for catering to varied dietary needs and preferences, accommodating different lifestyles, activity levels, and specific health objectives.

The ranges provided in the other options do not encompass the full scope of recommendations by dietary guidelines and research on optimal protein intake for different populations, which is why they do not align with the established recommendations. Using this range ensures adequate protein consumption while allowing a balanced intake of carbohydrates and fats, which are also essential for energy production and overall health.
