What is a potential consequence of consuming too little protein?

Consuming too little protein can lead to muscle loss and impaired recovery due to the critical role that protein plays in maintaining and repairing muscle tissue. Proteins are made up of amino acids, which are essential for muscle repair after exercise or injury. When the body does not receive enough protein, it may begin to break down muscle tissue to meet its amino acid needs, leading to muscle loss over time.

Additionally, inadequate protein intake can hinder recovery from workouts and injuries, as the body requires sufficient protein to rebuild and strengthen muscle fibers. This becomes especially critical for individuals engaged in regular physical activity or those involved in resistance training, where muscle maintenance and repair are essential for improving performance and preventing injury.

The other options do not accurately reflect the direct consequences of insufficient protein intake. Weight gain can occur for various reasons unrelated to protein consumption. Protein toxicity, while a possible concern with excessive protein intake, is not relevant in the context of consuming too little. Finally, a decrease in fat absorption is more closely linked to inadequate fat intake rather than protein levels. Thus, the correct answer highlights the significant implications of low protein consumption on muscle health.
