The Surprising Reasons Women Don’t Get Enough Protein

Ever wonder why you’re still hungry an hour after eating? Or why your energy crashes even after a ‘healthy’ lunch?” Most of the time, it’s not about carbs or calories. It’s about protein.

Here’s the thing. Most women simply don’t get enough protein. And when we don’t get enough, we feel tired, cranky, and hungry. But have you ever stopped to ask why women don’t get enough protein in the first place?

The reasons might surprise you. In this post, I talk about the most common ones. I also suggest simple, doable ways to fix it so you feel fueled, strong, and satisfied.

Reason #1 — We Eat Less, So We Get Less

Women often eat smaller meals than men. That alone can make it harder to meet daily protein needs. But dieting culture adds another layer. For decades, women were told to eat less, avoid “heavy” foods, and stick to low-calorie salads or fruit bowls. The result? Meals that look healthy but don’t have enough staying power.

This is one reason why women don’t get enough protein. When most of your plate is veggies or carbs, you might feel full in the moment but hungry an hour later. Protein is what helps keep you satisfied and steady.

Another issue is that many women simply don’t know how much protein they really need. According to the American Academy of Nutrition and Dietetics, the general recommendation is about 0.8 grams of protein per kilogram of body weight. For a 150-pound woman, that’s about 55 grams a day. And if you’re active, pregnant, or over 40, you may need even more.

Here’s the Fix

Build your meal around high-protein foods first. Add chicken, tofu, or fish to your salad. Stir beans into your soup. Swap plain toast for peanut butter toast. These small shifts can help you reach your daily target and give your body the fuel it needs.

Reason #2 — Plant-Based but Not Protein-Based Meals

More women are shifting toward plant-based eating. That’s a positive trend for health and the planet, but it comes with a challenge. Many plant-based meals are high in veggies and grains but light on protein. Without adequate planning, it’s easy to come up short.

This is another reason why women don’t get adequate protein. A smoothie with fruit and almond milk may look nutritious, but it might only have 3–4 grams of plant protein. That’s far below what your body needs to stay fueled and satisfied. You can add whey protein or casein protein powders to your smoothies to boost the protein content. And if you’re a vegetarian, use vegan protein powders.

As a registered dietitian, I remind women that variety is key. Beans, nuts, seeds, soy, quinoa, and whole grains all add protein. However, you often need to combine them to get all the essential amino acids your body can’t make on its own.

Here’s the Fix

Start by adding a clear protein source to every plant-based meal. Blend Greek yogurt or protein powder into your smoothie. Pair beans with rice or quinoa. Top your salad with tofu, tempeh, or roasted chickpeas. These swaps keep meals balanced and give your body the building blocks it needs.

Reason #3 — We Don’t Adjust Protein Intake for Different Stages of Life

Our protein needs don’t stay the same throughout life. They rise during pregnancy, breastfeeding, and after 40 as metabolism and hormones shift. But most women never adjust their eating habits to match these changes.

This is another reason why women struggle with consuming adequate protein. Menopause, for example, brings a natural decline in estrogen, which can speed up muscle and bone loss. Without enough protein, those changes hit harder. Older women also tend to eat less overall, which makes protein even easier to miss.

According to Harvard Health, protein plays a critical role in maintaining muscle and bone strength as we age. The standard RDA of 0.8 grams per kilogram of body weight is a baseline, but research shows women may need closer to 1–1.2 grams per kilogram to support healthy aging.

Here’s the Fix

Think of protein as your body’s repair kit. Add an extra serving at each meal once you hit midlife. Include protein-rich snacks like Greek yogurt, hummus with whole-grain crackers, or boiled eggs. If you’re pregnant or breastfeeding, work with a dietitian or healthcare provider to fine-tune your needs. Small increases in protein now pay off in energy, strength, and long-term health.

Reason #4 — Protein Is Getting Expensive

Another reason many women struggle to meet their protein needs is cost. The price of food has climbed across the board, and protein-rich staples haven’t been spared. Eggs, for example, have seen sharp price increases in recent years. Salmon, chicken, and lean beef are often among the most expensive items in the grocery cart.

When budgets are tight, it’s easy to turn to cheaper foods like pasta, rice, or bread. They fill you up, but they don’t deliver the same nutrition. Over time, this pattern leaves many women short on protein.

Here’s the Fix

Protein doesn’t have to drain your wallet. Affordable staples like canned beans, peanut butter, cottage cheese, and lentils are powerful options. Buy in bulk when you can, batch-cook on weekends, and keep quick proteins ready to grab. Even small shifts—like adding beans to pasta or pairing toast with nut butter—can stretch your grocery budget while keeping your protein intake strong.

And don’t overlook shelf-stable options like powdered eggs. They’re cost-effective, last a long time, and can be used in everything from baking to breakfast scrambles. I share more about how to use powdered eggs in this blog post

Reason #5 — Misinformation and Habit

Old diet messages run deep. For years, women were told to avoid meat, cut calories, and “eat light.” Protein is often framed as something for men or bodybuilders, not everyday women. These myths still shape how many women eat today.

This is one reason women often don’t get adequate protein. Habits form early—like skipping breakfast, grabbing a muffin instead of eggs, or making dinner that’s heavy on pasta and light on protein. Add in the popularity of fad diets or cleanses, and protein gets pushed even further down the list.

Many women also underestimate how much they need. The USDA MyPlate guidelines show that adults should aim for about 5–6 ounces of protein foods per day, depending on age and activity. In practice, that’s about a palm-sized portion at each meal. But without awareness, it’s easy to fall short.

Here’s the Fix

Bust the old myths. Protein isn’t just for bodybuilders—it’s for women who want steady energy, better focus, and strong muscles at every age. Make it a habit to include protein at every meal. That could mean eggs at breakfast, beans at lunch, and fish or tofu at dinner. If you find yourself asking, “How much protein do I need every day?” There are online tools to help. Use tools like the Protein Calculator to check your daily needs and see if you’re hitting your daily protein goals. Small changes in habit lead to big results over time.

Quick Tips to Get More Protein in Your Diet

If all of this sounds overwhelming, don’t worry. Meeting your protein needs doesn’t mean changing everything overnight. Start small and keep it simple.

• Add protein to every meal. Build your plate around chicken, tofu, beans, or fish first, then fill in with veggies and grains.
• Snack smarter. Trade chips or crackers for nuts, roasted chickpeas, string cheese, or Greek yogurt.
• Keep protein bars and shakes handy. They’re quick, portable, and can fill the gap when you’re on the go. Opt for bars with at least 6 grams of protein and shakes with at least 20 grams of protein.
• Try a smoothie upgrade. Blend in protein powder, cottage cheese, or nut butter to turn it into a real meal.
• Meal prep once a week. Boil eggs, roast chicken, or cook a big pot of lentils so you always have protein ready.
• Mix it up. Rotate between animal and plant proteins to get a variety of nutrients.
• Use MyPlate as a guide. The USDA MyPlate protein group shows what daily portions should look like in real food.

Here’s the Fix

Protein doesn’t have to be complicated. A little planning, a few swaps, and some prep go a long way. Focus on building meals that keep you fueled and satisfied, and you’ll naturally bring your protein intake where it needs to be.

Now, It’s Your Turn

Not getting enough protein shows up in ways we can’t ignore—low energy, constant hunger, and feeling less strong than we want to be. The good news? You have the power to change that with small, smart choices every day.

So now I’d love to hear from you. Which of these reasons sounds most like you? And what’s one simple change you can make this week to boost your protein?
