The 6 signs that you might not be eating enough protein are experiencing persistent fatigue, muscle loss or weakness, weak hair, skin, and nails, slow healing injuries, constant hunger or cravings and frequent illness.
Your body needs amino acids to regulate energy and repair cells.
And without enough protein, you might feel sluggish or exhausted after a full night of sleep.
Muscles also depend on protein to maintain and rebuild tissue.
And if your intake of protein is too low, your body breaks down muscle for fuel, which makes workouts harder or everyday tasks like climbing stairs feel difficult.
Hair, nails and skin also rely on structural proteins like keratin, elastin and collagen.
And a shortage of protein can lead to thinning hair, peeling nails, or dry, dull skin.
Cuts, scrapes, and bruises also take longer to mend without enough protein, because the body lacks the essential building blocks that are required for tissue regeneration and collagen production.
Without enough protein you may get sick more often as your immune system needs protein to produce antibodies that fight off bacteria and viruses.
Low intake of protein can also weaken your defenses and make you more prone to catching colds.
Protein also helps promote the feeling of fullness also known as (satiety) and stabilizes your blood sugar.
Eating too little protein can trigger sudden sugar cravings or even leave you feeling hungry shortly after a meal.
Protein levels in your body are checked using a simple blood test called a Total Serum Protein Test, which measures albumin and globulin.
How the Test Works for protein:
Blood Draw: A doctor uses a small needle to take a blood sample from a vein in your arm.
Urine Test: Sometimes, a urine protein test is also used to check if your kidneys are leaking protein.
Duration: The blood collection process takes less than five minutes.
Normal Ranges for protein include:
Total Protein: Typically 6.0 to 8.3 grams per deciliter (g/dL).
Albumin: Typically 3.5 to 5.5 g/dL.
Globulin: Typically 2.0 to 3.5 g/dL.
Note: Specific normal ranges for protein vary slightly depending on the laboratory used for analysis.
Why the Test is Done:
Liver Health: Checks if your liver is making enough proteins.
Kidney Health: Checks for protein leaks or kidney disease.
Nutrition: Evaluates your general nutritional status.
