Here are six warning signs that your body is not consuming enough protein, according to the Times of India.

Swelling (edema)

One of the most noticeable signs of protein deficiency is swelling, especially in the legs, feet, and hands. This occurs when the body lacks albumin, a protein that helps maintain fluid balance in the body. Research in the Journal of Clinical Investigation found that when protein is lacking, fluid leaks out of the blood vessels and builds up in the tissues, leading to swelling.

Weakness and muscle atrophy

Protein is important for muscle growth and maintenance. When you don't consume enough protein, your body starts to break down muscle tissue to meet its protein needs. This can lead to a condition known as muscle atrophy.

A study in the Journal of Clinical Investigation found that inadequate protein intake can lead to significant loss of muscle mass, especially in older adults, affecting their mobility, balance and overall strength.

Skin, hair and nail problems

Protein deficiency can also affect the health of your skin, hair, and nails. Proteins such as collagen and keratin are essential for maintaining the structure and integrity of these tissues. Without enough protein, your body can experience brittle nails, hair loss, rashes, and dry skin.

Research published in the Journal of Dermatological Science highlights that protein is important for the production of keratin - the main component of hair and nails.

Increased hunger

Protein plays an important role in regulating appetite and maintaining feelings of fullness. When the diet is low in protein, the body feels hungry and craves foods that are high in calories. This happens because protein affects the release of hormones that signal feelings of fullness.

Research in the Journal of Nutrition concluded that people who eat less protein feel hungrier and tend to eat more than those who consume enough protein.

Immunodeficiency

Protein plays an important role in the immune system. Protein creates antibodies and immune system cells. Without enough protein, the body will have difficulty fighting off diseases.

A study in the journal Clinical and Experimental Immunology demonstrates that protein deficiency can cause a decline in the number and function of immune cells.

Fatty liver

Another serious consequence of not consuming enough protein is fatty liver disease, a condition in which fat builds up in liver cells. This can lead to inflammation, liver damage, and even liver failure.

According to research published in the Journal of Hepatology , protein is essential for the transport and metabolism of fat in the liver. Without enough protein, fat builds up, leading to fatty liver disease.
