Food: Aging Well Starts with Protein

“You wouldn’t expect your car to run without fuel. Your muscles aren’t much different.”

As we get older, most of us notice a few unwelcome changes. Climbing stairs feels a little harder, carrying groceries takes a bit more effort, and recovering after a busy weekend seems to require… another weekend.

Many people assume these changes are simply “part of getting older.” While aging does play a role, losing muscle isn’t inevitable—and one of the biggest factors you can control is your protein intake.

Why Protein Becomes More Important with Age

Beginning around age 30, we naturally start to lose muscle mass, a process known as sarcopenia. After age 60, that loss can accelerate if we aren’t actively working to preserve it through exercise and proper nutrition.

Muscle isn’t just about looking toned. It’s what allows you to climb stairs, get up from a chair, carry your luggage through the airport, maintain your balance, and stay independent as you age.

Research from the PROT-AGE Study Group concluded that older adults generally need more protein than the current Recommended Dietary Allowance (RDA) to help preserve muscle mass, strength, and overall physical function. Rather than the minimum RDA of 0.8 grams per kilogram of body weight, many healthy adults over 65 may benefit from 1.0–1.2 grams of protein per kilogram of body weight each day, with even higher needs for those who exercise regularly or are recovering from illness.

Are You Getting Enough?

Let’s use a simple example.

A person weighing 150 pounds (68 kg) should aim for approximately 68–82 grams of protein per day.

Someone weighing 180 pounds (82 kg) may benefit from around 82–98 grams per day.

The surprise? Many adults aren’t even close.

A bowl of cereal, toast for lunch, and pasta for dinner may leave you feeling full, but they don’t provide nearly enough protein to support healthy muscles.

It's Not Just How Much—It's When

Many people eat very little protein throughout the day and then have a large serving with dinner.

Emerging research suggests your muscles respond better when protein is spread across the day rather than eaten all at once. A position paper from the International Society of Sports Nutrition recommends consuming approximately 20–40 grams of high-quality protein per meal to maximize muscle protein synthesis.

Think of it this way: your muscles prefer regular deposits into their “protein savings account” rather than one large payment at the end of the day.

Easy Ways to Increase Your Protein Intake

The good news is you don’t need to survive on grilled chicken and protein shakes.

Here are a few simple ways to boost your intake:

  • Start your day with eggs, Greek yogurt, or cottage cheese instead of toast alone.
  • Add grilled chicken, tuna, turkey, tofu, or beans to salads and soups.
  • Snack on Greek yogurt, edamame, roasted chickpeas, or a handful of nuts.
  • Include a quality protein source with every meal.
  • If you struggle to eat enough, a protein shake can be a convenient option, especially after exercise.

Small changes throughout the day can make a meaningful difference.

Pair Protein with Strength Training

Protein provides the building blocks—but your body still needs a reason to keep its muscle.

That’s where strength training comes in.

Research consistently shows that combining adequate protein intake with resistance exercise is one of the most effective strategies for maintaining muscle mass, improving strength, and supporting healthy aging. The American College of Sports Medicine Position Stand on Exercise for Older Adults highlights resistance training as a cornerstone of preserving physical function and independence as we age.

Think of strength training as sending your muscles a message:

“We’re still using these—don’t get rid of them.”
