Protein Deficiency: 9 Alarming Signals Most People Ignore.

According to ТСН: When the body does not get enough protein from food, it starts using its muscles to obtain the necessary amino acids. Even a slight deficiency can significantly affect well-being.

The publication discusses the main signs of this.

1. You are constantly tired

If you are getting enough sleep but still feel exhausted, the reason may lie in your diet.

'Chronic fatigue is a common phenomenon, as the body cannot effectively restore cells or regulate energy metabolism without sufficient protein,' explains dietitian Lia Tsui.

2. You are losing muscle

This is one of the most obvious symptoms. If climbing stairs has become harder or workouts are challenging, it may indicate a protein deficiency rather than age.

'When protein intake drops too low, your body starts breaking down muscle tissue to gather amino acids for essential processes,' notes Ashley Koff, founder of The Better Nutrition Program.

3. You are constantly hungry

Protein is one of the most satiating nutrients as it triggers the production of hormones that signal the brain about fullness. Without protein, even a large portion of food may not provide a lasting feeling of satiety.

A lack of protein can also lead to unstable blood sugar levels. Consuming a lot of carbohydrates and little protein can cause sharp fluctuations in glucose, prompting increased appetite.

4. Dull skin, weak hair, and nails

Hair and nails consist of keratin and collagen, which are proteins. When resources are insufficient, the body focuses its efforts on maintaining vital organs, sacrificing appearance.

'The most common early signs of low protein levels include fatigue, hair loss, and brittle nails,' says Lia Tsui.

5. You get sick more often

Protein not only helps build muscles but is also the foundation for antibodies that protect the body from infections. When protein is lacking, your body starts to allocate resources to support the immune system.

Doctor Glenn Jones explains: if you are not getting enough protein from food, the body starts breaking down its own muscles to obtain amino acids for immune support. As a result, you may get sick more often and take significantly longer to recover from even a common cold.

6. Problems with concentration

Feeling 'foggy' in the head, poor concentration, and mood swings may result from insufficient protein intake. Your brain needs amino acids to produce neurotransmitters like dopamine and serotonin.

A protein deficiency can also impair red blood cell formation, negatively affecting oxygen supply to the brain.

7. Slow recovery after exercise

During workouts, micro-tears occur in the muscles, and protein is necessary for their recovery. If pain doesn't subside, it may indicate that you lack 'building materials.'

Doctor Gabrielle Lyon notes that effective recovery is impossible without sufficient amino acids.

8. Edema

In more severe cases, protein deficiency can lead to an imbalance of fluids in the body, causing edema, often in the face, arms, or legs.

When protein is lacking, the body tries to preserve vital organs at the expense of fluid balance.

9. You are losing weight 'incorrectly'

If you notice weight loss but feel weakness and lethargy, you may be losing muscle instead of fat. This threatens to slow down metabolism.

Sudden weight loss accompanied by fatigue should be a cause for concern.

How much protein should you eat?

The average adult needs about 1 gram of protein per kilogram of body weight per day.

To improve health and maintain muscle mass, it is recommended to consume 1.2–2.0 grams. For a person weighing 68 kg, this is about 80–135 grams per day.

Doctor Gabrielle Lyon advises consuming 15–30 grams of protein at each meal.

Experts also recommend finding ways to increase protein content in the diet without losing food variety.
