7 Warning Signs Your Body May Be Low on Protein

Protein is essential for nearly every function in the body — from building muscles and repairing tissues to supporting immunity and hormone balance.

A prolonged deficiency can lead to noticeable health issues. Here are seven common signs that your body might be lacking in protein.

Muscle Loss or Weakness: Without enough protein, your body may start breaking down muscle tissue for energy, leading to muscle loss, weakness, and reduced strength.

Frequent Fatigue: Protein helps stabilize energy levels. If you’re often tired despite adequate sleep, low protein intake could be a contributing factor.

Slow Wound Healing: Protein plays a key role in tissue repair. If cuts and bruises take longer to heal, it may signal a deficiency.

Hair Thinning or Hair Loss: Hair is primarily made of keratin, a protein. Inadequate intake can lead to hair thinning, breakage, or loss.

Increased Hunger or Cravings: Protein promotes satiety. Constant hunger or sugar cravings may point to a lack of protein in your meals.

Weakened Immunity: Low protein levels can impair your immune system, making you more susceptible to infections and illnesses.

Swelling or Edema: Protein helps regulate fluid balance. Deficiency can cause fluid retention, especially in the legs, ankles, and feet.
