Inadequate protein intake can lead to several negative health effects, including muscle loss, weakened immune system, and impaired recovery from injuries and illnesses. Protein is essential for building and repairing tissues, producing enzymes, and maintaining overall bodily functions. Insufficient protein consumption can result in fatigue, poor concentration, and even mood swings due to the lack of essential amino acids. For those engaging in physical activity, low protein can hinder performance and muscle growth. Therefore, maintaining an appropriate protein intake is crucial for overall health and fitness.
