How Much Protein Do Women Really Need?

It’s a question I hear all the time from women, especially those in perimenopause and beyond. And it’s no surprise — as our hormones shift, our nutritional needs change too.

The truth is, your ideal protein intake depends on a few key factors: your age, how active you are, your current hormone balance, and whether you’re still having a monthly cycle. But there are some simple, science-backed guidelines that can help you find your footing.

In this blog, we’ll explore why protein is absolutely essential for women at midlife — from supporting metabolism and muscle tone to balancing blood sugar and hormones..

Why Protein is Non-Negotiable for Women’s Health

Protein isn’t just for gym-goers or bodybuilders. It’s absolutely essential for muscle repair, hormone balance, blood sugar stability, fat loss, and strong bones. It even plays a role in brain function and nervous system health.

As we get older, our bodies naturally become less responsive to both protein and resistance training. This means we need more of both to get the same benefits we enjoyed in our 20s.

For example, insufficient protein can lead to:

• Loss of lean muscle (sarcopenia)
• Slower metabolism
• Increased fat gain
• Poor blood sugar regulation
• Reduced bone density
• Cognitive decline

So, let’s look at how much you actually need.

How Much Protein Should I Be Eating?

The current recommended daily allowance (RDA) for protein is around 1g per kg of body weight (or 0.45g per pound). However, this is the minimum amount needed to prevent deficiency—not necessarily what’s optimal for health.

➤ For active women or those looking to support hormone health, fat loss, or muscle tone:

1.6–2.2g of protein per kg of body weight daily is ideal
(~0.7–1g per lb)

That means if you weigh 65kg (around 143lbs), you’d need around 104–143g of protein a day.

Protein Needs in Perimenopause and Menopause

During perimenopause and menopause, protein becomes even more important. Muscle mass naturally declines with age, and our bodies are less efficient at using the protein we eat to build and maintain muscle.

➤ For women over 40, especially those post-menopause:

Aim for 2–2.3g of protein per kg of body weight
(~1–1.2g per lb)

This higher intake helps to maintain lean muscle, manage weight, and support metabolism.

Protein Timing & Meal Structure

Research shows that evenly distributing your protein intake throughout the day—roughly every 4-5 hours—supports better muscle protein synthesis and body composition.

Aim for:

• 30–40g of protein per main meal (most important meals to get more protein in are breakfast and dinner).
• 15–20g in snacks if needed

Protein-Rich Foods to Include Daily

Here are some nourishing examples to help you hit your targets:

Animal-based:

• Organic eggs (6-7g protein per egg)
• Free-range chicken breast (~30g per 100g)
• Wild salmon or mackerel (~25g per 100g)
• Grass-fed beef or lamb (~26g per 100g)

Plant-based:

• Lentils and chickpeas (18g per cup cooked)
• Tofu or tempeh (~20g per 100g)
• Quinoa (8g per cup cooked)
• Pumpkin seeds or hemp seeds
• Chia pudding made with almond milk and plant protein powder

Can I Use a Protein Powder?

Absolutely! While real food should be your first go-to, clean protein powders are a brilliant option if you’re on the go, have a smaller appetite, or are struggling to reach your protein target.

My go-to is grass-fed whey isolate—it’s clean, easy to digest, and perfect in my morning protein coffee, especially after an early workout.

If you’re plant-based or sensitive to dairy, there are also excellent pea options available—just check they’re free from sweeteners, gums, and artificial additives. Take a look at some protein powder recommendations on the Pippa Loves page.
