Are You Eating Enough Protein? Why Women’s Needs Change as They Age

If you're a woman over 50, there's something I want you to take a closer look at when it comes to your nutrition: Are you actually eating enough protein?

For years, many of us have been conditioned to think about healthy eating in terms of cutting back. Fewer calories, smaller portions, less fat, fewer carbohydrates. And while managing our weight is certainly important, I want to encourage women to think a little differently about what their bodies need as they get older.

Because here's something that may surprise you: As we age, our muscles can become less responsive to the protein we eat when it comes to maintaining and building muscle.

That means getting enough protein becomes increasingly important, especially for women who want to stay strong, maintain a healthy weight, and remain active and independent well into their later years.

Why Your Body Needs More Protein as You Age

In my work as a fitness and nutrition coach, I often remind women that muscle is about more than appearance. It's one of our greatest assets for healthy aging.

In my recent AMAC Active article, Why Women Need to Think About Muscle Differently After 50, I explained why building and maintaining muscle is so important for women as we age. From supporting metabolism and bone health to protecting mobility and independence, our muscles play a much bigger role in our long-term health than many women realize.

But there's another important piece of the puzzle I want to talk about today: Are we giving our muscles the nutrition they need to stay strong?

Beginning as early as our 30s, we can gradually start losing muscle mass, and that process often becomes more significant as we get older. For women, hormonal changes associated with menopause can make preserving muscle even more challenging.

There's also something happening at the cellular level that I think every woman should understand. It's called anabolic resistance. As we age, our muscles may become less responsive to the signals that tell them to grow and repair, including those triggered by eating protein.

Think of it this way: The amount of protein that was sufficient to support your muscles at 30 may not have the same effect at 60.

Research shows that adequate protein, especially when combined with regular resistance training, can help older adults maintain and even build muscle. Our muscles don't stop responding as we age. We just need to give them the right support.

How Much Protein Do Women Over 50 Really Need?

Here's some encouraging news: Our national nutrition guidelines are placing greater emphasis on the importance of protein!

In January 2026, the U.S. Departments of Agriculture and Health and Human Services released the new Dietary Guidelines for Americans, 2025–2030, introducing an updated food pyramid that puts protein-rich, nutrient-dense foods front and center.

One of the most significant changes is the recommendation to consume 1.2–1.6 grams of protein per kilogram of body weight each day, adjusting for individual calorie needs.

That's considerably higher than the longstanding Recommended Dietary Allowance (RDA) of 0.8 grams per kilogram of body weight, which remains the established RDA for healthy adults.

Why the difference?

The RDA is designed to meet the protein requirements of nearly all healthy adults. But meeting basic nutritional requirements isn't necessarily the same as optimizing muscle maintenance, body composition, and healthy aging.

And for women over 50, that distinction is especially important.

Let's put these numbers into perspective.

For a woman weighing 150 pounds:

• Longstanding RDA (0.8 g/kg): Approximately 54 grams of protein daily.
• New dietary guidelines (1.2–1.6 g/kg): Approximately 82–109 grams daily.

That's a meaningful difference!

What's particularly encouraging is that these updated recommendations are consistent with research supporting the benefits of higher protein intakes for preserving lean muscle, particularly during weight loss or when combined with resistance training.

That doesn't mean every woman needs to double her protein intake. Many women already consume adequate amounts, and individual needs vary.

I don't want women to feel overwhelmed by these numbers or think they need to track every gram of protein they consume. But I do want you to recognize that eating enough protein deserves just as much attention as managing your calories.

And if you're strength training regularly or working to lose body fat without sacrificing valuable muscle, adequate protein becomes even more important.

Of course, women with kidney disease or other medical conditions that affect protein requirements should work with their healthcare provider or a registered dietitian to determine an appropriate intake.

Don't Save All Your Protein for Dinner

Here's something I see frequently: Women eat very little protein during the first half of the day and then consume most of it at dinner.

Maybe breakfast is a piece of toast and some fruit. Lunch is a salad or a bowl of soup. Then dinner includes a serving of chicken, fish, or another protein source.

The new Dietary Guidelines specifically encourage Americans to prioritize high-quality, nutrient-dense protein foods at every meal. That's a message I wholeheartedly support. Every time we eat a protein-rich meal, we provide our bodies with amino acids that help stimulate muscle protein synthesis—the process of building and repairing muscle tissue.

While getting enough total protein each day is the first priority, spreading that intake across meals is a practical strategy that may help support muscle maintenance as we age.

For many women, a reasonable starting point is to aim for approximately 25–35 grams of protein at breakfast, lunch, and dinner, adjusting portions based on individual needs. That's not a rigid rule, but it can be a helpful way to think about building balanced meals.

Protein Does More Than Build Muscle

One of the reasons I'm so passionate about helping women improve their protein intake is that its benefits extend well beyond building stronger muscles.

• Protein helps you feel fuller longer. If you've struggled with feeling hungry shortly after eating or find yourself constantly reaching for snacks, adding more protein to your meals may help. Protein tends to promote greater satiety, which can make managing your overall food intake easier.
• Protein helps protect muscle during weight loss. This is especially important for women in midlife and beyond. When we lose weight, we don't only lose body fat. We can lose valuable muscle tissue, too. Adequate protein, combined with resistance training, can help minimize that loss.
• Protein supports recovery from exercise. Whether you're lifting weights, attending a fitness class, or working to become more physically active, your muscles need amino acids to repair and adapt.
• I want women to stop thinking about protein as something that's only important for bodybuilders or serious athletes. It's a foundational nutrient for healthy aging.

Simple Ways to Eat More Protein

Some of you may be thinking: I don’t want to eat more food; I’m already trying to manage my weight. I understand that concern, and here's what I want you to know: Increasing your protein intake doesn't necessarily mean increasing your calories. Think about making a few strategic substitutions.

For example:

• At breakfast: Instead of toast and fruit alone, try plain Greek yogurt with berries, eggs with a side of cottage cheese, or a protein smoothie.
• At lunch: Add grilled chicken, tuna, turkey, tofu, or edamame to your salad rather than relying primarily on vegetables and dressing.
• At snack time: Replace crackers or pretzels with a protein-rich option, such as Greek yogurt, cottage cheese, or a small serving of lean turkey.
• At dinner: Make sure you're including a meaningful portion of protein alongside your vegetables and whole-food carbohydrates.

And don't overlook convenience. While I always encourage a whole-food-first approach to nutrition, a quality protein powder can be a helpful option for women who struggle to meet their needs through meals alone.

The goal isn't to eat enormous portions of meat or add protein shakes to everything. It's to make sure protein has a consistent place in your daily nutrition.

Small changes really do add up.

Try This Tomorrow: The Protein Challenge

I want to leave you with a simple challenge.

Tomorrow, I want you to focus on just one thing:

Include a meaningful source of protein at every meal.

Start with breakfast. Ask yourself, Where is my protein coming from?

Do the same thing at lunch and dinner.

You don't need to measure every bite or completely overhaul your diet. Just begin paying attention. If you're accustomed to eating very little protein in the morning, try adding one protein-rich food. If your lunch is usually a light salad, consider adding a substantial protein source.

And if you're already doing a great job with your protein intake, wonderful! Keep it up, and remember that regular strength training is an equally important part of protecting your muscles.

As a coach, one of the most important messages I want women to hear is that it's never too late to improve our strength, our nutrition, or our health. We can't stop the aging process, but we have more influence over how we age than many people realize.

And sometimes, the first step toward a stronger, healthier future is as simple as putting more protein on your plate.
