Protein is one of the most important nutrients your body needs—especially as you get older.
It plays a vital role in maintaining muscle mass, supporting your immune system, and keeping your energy levels steady throughout the day. Yet many Americans, particularly those over 50, may not be getting enough protein without even realizing it.
If you’ve been feeling “off” lately, your diet could be part of the reason. Here’s how to tell if you might be falling short—and what you can do about it.
Why Protein Matters More Than You Think
Protein isn’t just for athletes or bodybuilders. It’s essential for everyday health. Your body uses protein to build and repair tissues, produce enzymes and hormones, and maintain strong bones and muscles.
As you age, your body naturally loses muscle mass—a process known as sarcopenia. Without enough protein, this process can speed up, leading to weakness, fatigue, and a higher risk of falls.
Common Signs You’re Not Eating Enough Protein
1. You Feel Tired All the Time
If you’re constantly low on energy—even after a full night’s sleep—your body may be lacking the nutrients it needs to function efficiently. Protein helps stabilize blood sugar levels, preventing energy crashes throughout the day.
2. You’re Losing Muscle or Strength
Notice that everyday tasks like carrying groceries or climbing stairs feel harder? Protein is crucial for maintaining muscle. Without enough, your body may start breaking down muscle tissue to meet its needs.
3. You’re Always Hungry (Even After Eating)
Meals that are low in protein tend to leave you feeling unsatisfied. Protein helps you feel full longer, so a deficiency may lead to frequent snacking or overeating.
4. Your Hair, Skin, or Nails Are Suffering
Protein is a building block of hair, skin, and nails. If you notice thinning hair, brittle nails, or dull skin, your diet might be lacking in essential amino acids.
5. You Get Sick More Often
Your immune system relies on protein to produce antibodies. Without enough, your body may struggle to fight off infections, leaving you more vulnerable to colds and other illnesses.
6. Swelling in Your Legs or Feet
Severe protein deficiency can lead to a condition called edema, where fluid builds up in tissues—often in the legs, feet, or hands.
How Much Protein Do You Actually Need?
Most adults should aim for at least 0.8 grams of protein per kilogram of body weight daily. However, many experts suggest that older adults may benefit from higher intake—closer to 1.0–1.2 grams per kilogram—to preserve muscle and strength.
For example:
- A 180-pound adult (about 82 kg) may need 65–100 grams of protein per day
