Feeling constantly tired and lacking energy can be a sign of low protein intake. Protein is essential for repairing tissues and maintaining energy levels.
2. Loss of Muscle Mass
Protein is crucial for muscle growth and repair. A deficiency can lead to muscle loss, decreased strength, and changes in body composition.
3. Brittle Hair and Nails
Hair, nails, and skin are made up of proteins like keratin. Insufficient protein can cause brittle or thinning hair, dry skin, and weak nails.
4. Frequent Illness
Protein is vital for a healthy immune system. Low protein levels can weaken your immune response, making you more susceptible to infections.
5. Slow-Healing Injuries
Protein is necessary for the production of collagen, which helps in wound healing. A lack of protein can slow down the healing process of cuts and injuries.
6. Swelling (Edema)
Protein helps maintain fluid balance in your body. A deficiency can cause swelling, especially in the abdomen, legs, feet, and hands.
7. Mood Changes
Proteins are involved in the production of neurotransmitters. Low protein intake can affect your mood, leading to feelings of depression or irritability.
8. Increased Hunger
Protein helps you feel full. If you’re constantly hungry despite eating regular meals, you might need more protein in your diet.
9. Weakness and Fatigue
Even a short period of low protein intake can affect your muscles, leading to weakness and fatigue. This is especially true for older adults.
