Carlos wants to build muscle. Which of the following are general nutrient intake percentage recommendations that will support Carlos's goal?

The recommended macronutrient intake for someone looking to build muscle generally highlights the importance of protein for muscle repair and growth. A protein intake of about 35% is well-supported for those aiming to increase muscle mass, as this provides sufficient amino acids necessary for muscle synthesis.

In addition to protein, carbohydrates play a critical role in fueling workouts and replenishing glycogen stores. The suggested intake of 45% carbohydrates aligns with the need for energy during strength training and recovery, ensuring that the body has enough fuel for high-intensity exercises and can perform effectively.

A fat intake of 20% is appropriate as it supports overall health and hormone production, which is vital for muscle growth. Having a balanced distribution of macronutrients with this ratio allows for an adequate amount of energy while prioritizing protein to support muscle-building goals effectively.

Other options indicate lower protein levels or higher carbohydrate percentages, which may not provide enough protein for optimal muscle growth or could compromise the individual's ability to recover and build tissue effectively.
