🧠 8 Signs You’re Not Eating Enough Protein
- Persistent Muscle Soreness
Muscle recovery lags when protein is low, making soreness linger longer post-workout. - Decreased Strength & Performance
Struggling to hit your fitness targets? A protein deficit could be sabotaging your strength and endurance. - Frequent Fatigue
Low energy throughout the day could mean your metabolism isn’t getting enough protein to run efficiently. - Slow Injury Recovery
Tissues need protein to heal. If cuts, bruises, or sprains are slow to mend, protein might be lacking. - Increased Body Fat
Without enough protein to support lean muscle mass, metabolism slows — making fat gain more likely. - Weakened Immunity
Protein fuels your immune cells. Falling ill more frequently may indicate poor protein intake. - Hair Thinning & Brittle Nails
Keratin, a protein, forms the structure of hair and nails. A shortage may lead to weak, breakable strands. - Cravings & Overeating
Inadequate protein throws hunger hormones off balance, often causing intense sugar cravings and overeating.
Swinney urges listeners to track their daily intake and consider adding more high-protein foods like eggs, Greek yogurt, lean meats, lentils, and nuts to restore balance.
