11 Alarming Signs That Your Body Isn't Getting Enough Protein

Protein is an essential macronutrient that is necessary for optimal health. It plays a critical role in building and repairing tissues in the body, including muscles, bones, and organs. Proteins are made up of amino acids, the body's building blocks. The body cannot function optimally without adequate protein, leading to various health issues. This blog looks at the different forms of protein deficiency diseases and 11 symptoms that indicate your body is not getting enough.

Is Your Body Craving Protein? Signs That You Might Be Protein-Deficient

Proteins also play a critical role in the body's production of enzymes, hormones, and other essential molecules. Our body requires protein to function optimally, and not getting enough can lead to various health issues. Here are a few signs that your body isn't getting enough protein.

1.    Muscle Loss

Muscle loss is one of the most significant signs that your body isn't getting enough protein. Protein is essential for building and maintaining muscle mass. If your body isn't getting enough protein, it will start breaking down muscle tissue to meet its protein requirements. If you notice a significant decrease in your muscle mass, it may be a sign that you need to increase your protein intake. 

2.    Slow Recovery After Exercise  

Protein is crucial for repairing and rebuilding muscles after exercise. If your body isn't getting enough protein, you may notice that your muscles are slow to recover after a workout. You may also experience more muscle soreness than usual after exercise. Consuming enough protein after exercise is essential to promote muscle recovery and prevent muscle damage. 

3.      Constant Hunger

Protein is filling and helps you feel satisfied after a meal. If your body needs enough protein, you may always feel hungry, even after eating a meal which can lead to overeating and weight gain. More protein-rich foods can help you feel fuller for extended periods and prevent overeating.

4.      Weak Immune System

Protein is critical for the immune system to function correctly. It plays a vital role in producing antibodies and immune cells that help fight infections. You may be more susceptible to infections and illnesses if your body isn't getting enough protein. A weak immune system is a clear sign that you need to increase your protein intake.

5.      Slow Healing

Protein is essential for the repair and growth of tissues in the body, including skin, bones, and organs. If your body isn't getting enough protein, you may notice that your wounds take longer because your body doesn't have enough protein to repair the damaged tissue.

6.      Edema

Oedema accumulates fluid in the body's tissues, leading to swelling. Protein is essential for maintaining fluid balance in the body. If your body isn't getting enough protein, you may experience swelling in your feet, ankles, and legs due to fluid retention

7.      Hair Loss

Protein is crucial for healthy hair growth. If your body isn't getting enough protein, you may notice that your hair is thinning or falling out. Consuming enough protein can help promote healthy hair growth and prevent hair loss.

8.      Brittle Nails

Protein is also essential for healthy nails. If your body isn't getting enough protein, you may notice that your nails are brittle and break easily. Consuming more protein-rich foods can help promote healthy nails and prevent nail damage.

9.      Mood Swings

Protein is critical for producing neurotransmitters, which regulate mood and behaviour. If your body isn't getting enough protein, you may experience mood swings, irritability, and anxiety. Consuming enough protein can help regulate your mood and prevent these symptoms.

10.  Fatigue

Protein is necessary for energy production in the body. If your body isn't getting enough protein, you may feel fatigued and lack energy. Consuming more protein can help increase your energy levels and prevent fatigue.

11.  Low Blood Pressure

Adequate protein intake is crucial in regulating blood pressure. Inadequate protein consumption may lead to low blood pressure, which can cause dizziness, fatigue, and fainting. To prevent such symptoms, it is advisable to consume more protein-rich foods. It is important to note that while low blood pressure may be a sign of protein deficiency, it may also be caused by underlying medical conditions.

If you experience any protein deficiency symptoms, seek medical attention to identify the root cause and prevent the risk of protein deficiency-related diseases. You will be surprised at the number of diseases caused by protein deficiency.

Causes of Protein Deficiency in Adults and Children: Understanding Why It Happens

Protein deficiency can occur for various reasons, including a lack of protein in the diet, digestive issues, ageing, medical conditions, or picky eating habits. Here are the common causes of protein deficiency in adults and kids:

Common Reasons for Protein Deficiency in Adults:

1.    Poor Diet: 

One of the most common causes of protein deficiency in adults is a poor diet that lacks adequate protein - particularly true for people who follow restrictive diets or consume mainly processed and junk foods.

2.    Digestive Issues:

 Digestive issues such as inflammatory bowel disease (IBD), celiac disease, and chronic diarrhoea can interfere with protein absorption and cause protein deficiency.

3.    Ageing: 

As we age, our bodies become less efficient at digesting and absorbing protein, which can lead to a deficiency if the diet doesn't provide enough protein.

4.    Medical Conditions: 

Certain conditions, such as liver or kidney disease, cancer, and HIV/AIDS, can lead to protein deficiency.

Common Reasons For Protein Deficiency In Kids:

1.    Poor Infant Feeding: 

Babies who are not breastfed or formula-fed adequately may need more protein and other essential nutrients.

2.    Picky Eating: 

Kids who are picky eaters and refuse to eat protein-rich foods such as meat, eggs, and beans may develop protein deficiency.

3.    Poverty:

 Families living in poverty may struggle to provide their children with enough protein-rich foods, leading to protein deficiency.

4.    Digestive Issues: 

Digestive issues such as celiac disease, Crohn's disease, and ulcerative colitis can interfere with protein absorption and cause protein deficiency in kids.

5.    Growth Spurts: 

Children go through growth spurts during which their bodies need more protein to support rapid growth. If they don't consume enough protein, it can lead to protein deficiency.

It is essential to be aware of these causes and take steps to ensure that you or your children get enough protein through a balanced diet and appropriate medical interventions.

Boost Your Protein Intake with These Vegetarian Sources

Protein is an essential nutrient required to grow and repair the body's tissues. It is commonly associated with animal products such as meat, poultry, and fish. However, for vegetarians and vegans, it is important to find alternative protein sources to meet their daily protein requirements. Here are some protein sources for vegetarians and non-vegetarians:

Protein Sources for Vegetarians:

1.    Legumes: 

Kidney beans and chickpeas

Lentils, chickpeas, black beans, kidney beans, and other legumes are excellent protein sources for vegetarians. They are also high in fibre, iron, and other essential nutrients.

2.    Tofu and tempeh: 

Soy products like tofu and tempeh are excellent protein sources. They can be used in various dishes and are available in many forms.

3.    Nuts and seeds: 

organic nuts and seeds - i say organic

Quinoa is a superfood high in protein and other essential nutrients and can be used in salads, soups, and other dishes.


To summarise, protein deficiency is a serious concern as protein is an essential macronutrient crucial for the proper growth, repair, and functioning of the body's tissues. Lack of protein intake can result in a range of health issues. This blog has discussed various protein deficiency symptoms that can serve as warning signs, including fatigue, muscle weakness, and hair loss. By being aware of these symptoms and increasing protein intake, individuals can help prevent protein deficiency diseases and maintain their overall health and well-being.


Q1: How can you prevent protein deficiency in kids?

A: Ensure they have a balanced diet that includes a variety of protein-rich foods. Encouraging healthy eating habits from an early age, providing protein-rich snacks, and seeking medical care for digestive issues can also help prevent protein deficiency in kids.

Q2: How can you know if a kid or older person is deficient in proteins?

A: Signs and symptoms of protein deficiency in kids and elderly persons include muscle wasting, delayed growth, thinning hair, skin dryness or discolouration, oedema, fatigue, weakness, and a weakened immune system.

Q3: Are proteins important for diabetic people?

A: Proteins are important for diabetic persons as they help regulate blood sugar levels and improve insulin sensitivity. Protein also helps control hunger and keeps people feeling fuller for extended periods, aiding in weight management for diabetic persons. However, it's important to consult a healthcare professional or registered dietitian for personalised advice on protein intake for diabetic persons.
