What are the consequences of a low-protein diet?

A low-protein diet can lead to significant consequences for the body, particularly in areas such as muscle maintenance and immune health. Protein is essential for building and repairing tissues, which includes muscle tissues. When the body does not get enough protein, it may start to break down muscle fibers for energy and to meet its protein needs, leading to muscle loss.

Additionally, proteins play a vital role in the functioning of the immune system. They are involved in the synthesis of antibodies, enzymes, and various immune cells that protect the body from infections and diseases. A deficiency in protein can diminish the body’s ability to mount an effective immune response, resulting in increased susceptibility to infections and illnesses.

This understanding of protein's critical roles highlights how insufficient intake can adversely impact muscle mass and the immune system, making it clear why the response indicates muscle loss and weakened immune function as the consequences of a low-protein diet.
