Without adequate protein, the body fails to perform critical functions properly. Some common effects of low protein intake include:
Muscle loss and weakness: Without sufficient protein, your body breaks down muscle tissue to meet essential needs.
Slow recovery and poor healing: Cuts, injuries, and infections take longer to heal because your body lacks the building blocks to repair tissues.
Weakened immunity: Antibodies and immune cells rely on amino acids from protein; deficiency can increase susceptibility to illness.
Fatigue and low energy: Proteins help regulate hormones and enzymes that control metabolism; inadequate protein can make you feel constantly tired.
Hair, skin, and nail problems: Proteins like keratin and collagen are essential for hair, skin, and nails. Low protein intake can cause brittle nails, hair loss, and sagging skin.
