Here are five warning signs that your body may need more protein

Protein builds muscle, supports metabolism, nurtures hair, skin, nails and keeps you full. 

If you feel hungry soon after meals, low protein could be the cause. 

Cuts and scrapes taking too long to heal.

Not gaining muscles. 

Unexplained hair thinning could signal inadequate protein

Brittle, weak nails can mean your diet isn’t supplying enough protein for keratin production

Boost protein gradually: add Greek yogurt, eggs, cottage cheese, or a protein shake
