How much protein should a woman over 50 eat per day?

Current research recommends 1.2–1.6 grams of protein per kilogram of body weight daily for active women over 50. For a 70kg woman, that works out to 84–112g per day. This is significantly higher than the standard Australian recommendation of 0.75g/kg because after 50 your body becomes less efficient at using protein to build muscle (anabolic resistance). The key is spreading your intake evenly across three meals — aiming for 25–35g per meal rather than loading it all into dinner.

What are the best high-protein breakfast ideas for women over 50?

Great high-protein breakfasts for women over 50 include: two eggs on sourdough with avocado (25g protein), Greek yoghurt with berries and almonds (24g protein), a protein smoothie with milk, banana, and nut butter (20–25g protein), cottage cheese on toast with smoked salmon (28g protein), or overnight oats made with milk and topped with seeds and yoghurt (18–22g protein). The goal is hitting at least 25g at breakfast to support muscle maintenance and keep you energised until lunch.

Is it possible to get enough protein without eating meat after 50?

Absolutely. Plant-based proteins can meet your needs, but it requires more planning. The best plant protein sources include lentils (18g per cup), tofu (18g per 150g), chickpeas (15g per cup), edamame (17g per cup), and quinoa (8g per cup). The key is combining different plant proteins throughout the day to get all essential amino acids. Adding dairy like Greek yoghurt (20g per 200g) and eggs (12g for two) makes it significantly easier. Many vegetarian women over 50 also benefit from a collagen or plant-based protein powder to bridge any gaps.

What happens if you don't eat enough protein after 50?

Not getting enough protein after 50 accelerates muscle loss (sarcopenia), which can reduce your metabolism by 2–3% per decade, weaken your bones and increase fracture risk, slow recovery from exercise and injury, impair immune function making you more susceptible to illness, and contribute to fatigue and low energy levels. Research from the University of Sydney found that adults over 50 who ate below the recommended protein intake had 40% greater risk of frailty. Prioritising protein at every meal is one of the most impactful things you can do for healthy ageing.

Should women over 50 use protein powder or supplements?

Whole food protein sources are always best, but protein powders can be a helpful tool if you struggle to hit your daily target through food alone. Whey protein is the most researched and effective option — it's rich in leucine, the amino acid that triggers muscle building. If you're dairy-free, pea protein or a blended plant protein powder works well. Look for products with minimal added sugar and at least 20g of protein per serve. That said, most women can meet their needs through food — a tub of Greek yoghurt, two eggs at breakfast, and a palm-sized portion of meat or fish at lunch and dinner usually gets you there.

Your Protein Cheat Sheet After 50

Why Protein Matters More After 50

Here's something most women don't realise: after 50, your body becomes less efficient at using protein to build and maintain muscle. Scientists call this anabolic resistance — and it means you actually need more protein than you did in your 30s and 40s, not less.

Without enough protein, you lose muscle mass faster (a condition called sarcopenia), your bones weaken, your metabolism slows, and recovery from exercise takes longer. The good news? Eating the right amount of protein at each meal can counteract all of this.

This cheat sheet gives you a quick-reference guide to the best protein sources, their serving sizes, and exactly how many grams of protein you're getting. Save it, print it, stick it on the fridge — whatever works for you.

How Much Protein Do You Actually Need?

The current Australian recommendation for women over 50 is 0.75g per kilogram of body weight per day. But here's the thing — most researchers specialising in ageing now say that's too low. The updated recommendation from the International Society of Sports Nutrition is:

1.2–1.6g of protein per kg of body weight per day for active women over 50
For a 70kg woman, that's 84–112g of protein per day
Spread across 3 meals, that's roughly 25–35g per meal

The key is spreading your protein intake evenly across the day rather than loading it all into dinner (which is what most of us tend to do).

Best Protein Sources: Meat & Fish

Animal proteins are "complete" proteins, meaning they contain all nine essential amino acids your body needs. They're also the richest sources of leucine — the amino acid that triggers muscle building.

Chicken breast (150g cooked) — 46g protein. The classic lean protein. Grill, bake, or air-fry for a quick meal.
Lean beef (150g cooked) — 42g protein. Also rich in iron and B12, which many women over 50 are low in.
Salmon fillet (150g cooked) — 38g protein. Double win — you get protein plus omega-3 fatty acids for heart and brain health.
Prawns (150g cooked) — 36g protein. Low in calories, high in protein, and incredibly versatile.
Tinned tuna (1 can, 95g drained) — 20g protein. A quick, affordable option for lunch. Go for tuna in springwater over oil.
Turkey mince (150g cooked) — 40g protein. A leaner alternative to beef mince for bolognese, meatballs, or stir-fries.

Best Protein Sources: Dairy & Eggs

Dairy proteins are particularly effective for muscle building because they're rich in both whey and casein protein. Bonus: they also provide calcium for bone health.

Greek yoghurt (200g tub) — 20g protein. Choose plain, full-fat or low-fat — both are great. Add berries and a drizzle of honey for a perfect snack.
Cottage cheese (1 cup / 226g) — 28g protein. An underrated powerhouse. Pair with crackers, use in salads, or blend into smoothies.
Eggs (2 large) — 12g protein. Affordable, versatile, and packed with nutrients. Don't skip the yolks — they contain most of the vitamins.
Milk (250ml glass) — 9g protein. An easy way to boost your intake. Great in smoothies or with breakfast cereal.
Cheddar cheese (30g slice) — 7g protein. Small amounts add up. Add to salads, omelettes, or wraps.

Best Protein Sources: Plant-Based

Plant proteins are important even if you're not vegetarian — they come packed with fibre, antioxidants, and other nutrients that animal proteins don't provide. For the best results, combine different plant proteins throughout the day.

Lentils (1 cup cooked) — 18g protein. Plus 15g of fibre. Perfect in soups, salads, and curries.
Tofu, firm (150g) — 18g protein. Press, marinate, and pan-fry for the best texture and flavour.
Chickpeas (1 cup cooked) — 15g protein. Roast them for a crunchy snack, or blend into hummus.
Edamame (1 cup) — 17g protein. A brilliant snack straight from the freezer. Season with sea salt.
Almonds (30g handful) — 6g protein. A convenient on-the-go snack that also provides healthy fats and vitamin E.
Quinoa (1 cup cooked) — 8g protein. One of the few plant foods that's a complete protein. Use as a base for salads or instead of rice.

Quick Protein-Boosting Hacks

Sometimes you don't need to overhaul your entire diet — you just need a few clever swaps and additions to boost your protein without thinking too hard about it:

Add Greek yoghurt to smoothies, overnight oats, or as a sour cream substitute
Stir collagen powder (10g protein per scoop) into your morning coffee or tea
Swap regular bread for high-protein bread (some brands have 10g+ per slice)
Keep tinned fish in the pantry — tuna, salmon, and sardines are instant protein
Add an extra egg to your scramble or omelette
Snack on cottage cheese instead of crackers alone
Sprinkle seeds (hemp, chia, pumpkin) onto salads and yoghurt bowls

Sample High-Protein Day

Here's what a day of eating 100g+ of protein could look like — without any protein shakes or supplements:

Breakfast: 2 eggs on sourdough with avocado + a glass of milk = ~25g protein
Morning snack: Greek yoghurt with berries and almonds = ~24g protein
Lunch: Chicken and chickpea salad with feta = ~35g protein
Afternoon snack: Cottage cheese on crackers = ~15g protein
Dinner: Salmon fillet with quinoa and vegetables = ~42g protein

Total: approximately 141g of protein — well above the recommended range, from whole foods alone.

The Bottom Line

Getting enough protein after 50 doesn't have to be complicated. It's not about counting every gram obsessively — it's about making smart choices at each meal and being intentional about including a protein source every time you eat.
