What are the signs you are not eating enough protein?

Your body gives several clear signals when protein intake is too low. You may feel constantly hungry shortly after meals because protein is the most satiating macronutrient. Muscle loss or weakness is a major sign, as your body breaks down muscle tissue for amino acids. Slow wound healing, frequent illness, and getting sick often indicate a weakened immune system from inadequate protein. You might also notice brittle nails, thinning hair, or dry skin. Fatigue and low energy are common, along with difficulty concentrating. Swelling or puffiness, particularly in the legs and feet, can occur due to low albumin levels affecting fluid balance. Cravings for protein-rich foods can also be a telling signal.
