If you've been feeling less than great lately, be careful: it could be a sign that your body is in desperate need of protein. Your body needs protein to function. That's why it's called the building block of life.
And when you lack this building block, your body gives you many signals telling you that it needs this nutrient because the amount you eat is not enough. Here are 7 signs that you may have a protein deficiency:
1. Increased hunger
Increased food cravings and the need to snack frequently between meals can be signs that you are lacking protein. Protein is the most satiating nutrient, which means it helps keep you fuller for longer.
2. Muscle Weakness or Joint Pain
Lack of protein can lead to muscle loss. One study found that older men and women who consumed low amounts of protein had a higher rate of muscle loss.
Animal protein is especially good for joints, as the collagen in these protein sources helps relieve joint pain. One study found that daily protein intake can relieve pain in patients with osteoarthritis.
3. Slow wound healing
Studies have shown that we need enough protein to heal and rebuild new cells, tissues, and skin.
One study also found that consuming protein can speed up the healing of hip fractures in older adults. In other words, protein deficiency can significantly delay recovery time if you ever sustain an injury.
4. Problems with hair, skin and nails
