Protein is essential for maintaining muscle mass and plays a critical role in the structure and function of muscles. Protein deficiency is when your intake is unable to meet your body's requirements, and while true protein deficiency is uncommon in the Western world, it could present a wide range of symptoms. This includes muscle and joint pain, muscle loss, and muscle weakness. However, it is important to note that the amount of protein needed can vary depending on the individual, and there are many causes of low protein levels, including malnutrition, pregnancy, eating disorders, liver disorders, kidney problems, and inflammatory bowel diseases.

What You'll Learn
Low protein can cause muscle loss and fatigue
Protein is one of the essential nutrients our body needs to function properly. It is found everywhere in the body, including the muscles, skin, hair, bones, and blood. Protein fuels you and is one of three sources of calories, along with carbohydrates and fats.
Protein is critical for building and repairing muscle tissue. When dietary protein is lacking, the body pulls from its reserves in the muscles, which can lead to muscle loss and fatigue. This can cause muscle pain and tightness and make it harder to keep your balance.
Over time, a lack of protein can make you lose muscle mass, which in turn cuts your strength and slows your metabolism. Protein is also essential for maintaining energy levels, and a lack of protein can result in constant tiredness and a lack of stamina.
A diet with sufficient protein is important for athletes and other active people. Serious athletes with strenuous training schedules need about twice as much protein as the average person, or roughly 0.5-1 gram of protein per pound of body weight each day.

It can weaken your immune system
While true protein deficiency is uncommon in the Western world, it can still occur and have adverse effects on the body. Protein is vital for the immune system, and a deficiency may reduce immunity and increase the risk of infection.
Protein is the foundation of red blood cells, white blood cells, and antibodies. These components work together to fight off bacteria, viruses, and other pathogens in the body. Amino acids in the blood help the immune system make antibodies, which activate white blood cells to fight off harmful substances.
A protein deficiency can cause a reduction in antibodies and white blood cells, weakening the immune system's ability to defend the body. This can lead to frequent illnesses and a slower recovery from wounds and injuries. Studies have shown that athletes who consumed a low-protein diet experienced more upper respiratory tract infections than those on a high-protein diet.
Additionally, protein is essential for maintaining healthy skin. A deficiency can lead to dry, flaky skin and delayed wound healing due to insufficient collagen production. Collagen is found in connective tissues and the skin, and it is needed to make blood clot. Therefore, a lack of protein can result in slower healing processes, further exposing the body to potential infections.
In summary, low protein levels in the blood can weaken the immune system by reducing the body's ability to produce antibodies and white blood cells, leading to frequent illnesses and slower recovery from wounds. It can also cause dry skin and insufficient collagen production, further compromising the body's defence mechanisms.

It can lead to hair loss and brittle nails
Hypoproteinemia, or low protein in the blood, is a condition that can occur due to inadequate dietary protein intake or certain health conditions. While it is uncommon in developed countries, it can lead to various symptoms, including muscle cramps, weakness, fatigue, and frequent illnesses.
One of the telltale signs of chronic protein deficiency is the impact on hair and nails. Dietitian Nichola Ludlam-Raine explains that a lack of protein can cause hair and nails to become weak, thin, dry, brittle, and more susceptible to damage. This is because proteins like keratin play a crucial role in the structure and function of the cells that make up the body's organs and tissues.
Protein is an essential macronutrient, and every cell in our body needs it to function correctly. When the body does not receive adequate protein, it can lead to hair loss and brittle nails, among other symptoms. The hair may become weak, dry, and brittle, indicating insufficient protein intake. Optimising daily protein intake can help strengthen hair follicles and promote renewed growth and vibrancy.
Additionally, adequate protein intake is crucial for nail health. Protein-rich diets help maintain nail strength and reduce brittleness. Ensuring a sufficient intake of high-quality protein sources can support overall nail health and reduce breakage.
It is important to note that individual requirements for optimal protein intake vary depending on factors such as activity levels, dietary patterns, age, and fitness goals. Healthcare professionals can provide guidance on managing protein levels and making necessary dietary changes to improve hair and nail health.

It can cause frequent illnesses
While true protein deficiency is uncommon in the Western world, some people may experience low protein levels in their blood. This can be caused by malnutrition, pregnancy, eating disorders, liver disorders, kidney problems, inflammatory bowel diseases, or certain medications. Protein is critical for muscle health, and a deficiency can lead to muscle pain, weakness, and loss. In addition to these physical symptoms, low protein levels can also cause frequent illnesses.
Protein is key to a strong immune system. It is the foundation of red blood cells, white blood cells, and antibodies, which work together to fight off bacteria, viruses, and other pathogens. A deficiency in protein can lead to a weakened immune system, making individuals more susceptible to illnesses and infections. Studies have shown that athletes who consumed a high-protein diet experienced fewer upper respiratory tract infections than those on a low-protein diet.
Furthermore, low protein levels can cause a decrease in the production of antibodies, which are essential for fighting off infections. This decrease in antibodies is due to the reduced number of white blood cells, which are responsible for producing them. As a result, individuals with low protein levels may find that they get sick more often and take longer to recover from illnesses.
The link between low protein levels and frequent illnesses is particularly important for athletes and other active individuals, who are more susceptible to protein deficiency due to their increased physical demands. Ensuring adequate protein intake through a balanced diet or supplements can help maintain a healthy immune system and reduce the risk of frequent illnesses.
In addition to its impact on the immune system, protein also plays a crucial role in maintaining muscle health. Protein is essential for building and repairing muscle tissue. A deficiency in protein can lead to muscle pain, weakness, and loss, as the body breaks down muscle tissue to compensate for the lack of protein. This can further contribute to overall weakness and fatigue, making individuals more susceptible to illnesses and infections.

It can cause edema (swelling)
Low protein in the blood can cause edema, or swelling, especially in the abdomen, legs, feet, and hands. Edema is a condition characterised by swollen and puffy skin. It is caused by low levels of albumin, the protein that helps keep fluid from building up in tissues by maintaining oncotic pressure. Oncotic pressure is the force that draws fluid into the blood circulation, preventing fluid accumulation in tissues or body compartments. When there is a severe protein deficiency, oncotic pressure decreases, resulting in fluid accumulation and swelling. While edema is a symptom of severe protein deficiency, it may be caused by various factors, so it is essential to consult a doctor for proper diagnosis and treatment.

- Frequent illnesses
Low protein in the blood can be caused by malnutrition, pregnancy, eating disorders, liver disorders, kidney problems, inflammatory bowel diseases, and certain medications.
Yes, low protein in the blood can cause muscle cramps. This is because muscles need protein to stay strong and maintain mass. When the body doesn't get enough protein, it breaks down muscle tissue, leading to muscle weakness and pain.
