How Much Protein Do Australian Women Actually Need? (Honest Guide 2026)

The protein conversation has been hijacked at both ends. On one side, TikTok and fitness influencers insist every woman needs 130-150g of protein daily and should be obsessing over their macros at every meal. On the other, Dietitians Australia’s president recently told SBS that the "high protein" trend is "a social media-birthed trend not based on current scientific research findings" and that most Australians already eat enough.

Both of these positions contain truth and oversimplification in roughly equal measure. The actual answer depends on who you are, and it’s more interesting than either camp is letting on.

The official baseline and why it’s insufficient for many women

The NHMRC recommendation for adult women aged 19-70 is 0.75g of protein per kilogram of body weight per day. For a 70kg woman, that’s 52.5g — achievable in a typical Australian diet without any deliberate effort.

Here’s the problem with stopping there: the official recommendation is calibrated to prevent deficiency in a sedentary population. It’s a floor, not an optimal target. A 2026 CSIRO report — based on over 20 years of clinical research — found this baseline is genuinely insufficient for several groups of women:

Women in perimenopause and menopause require approximately 1.0-1.2g/kg per day to support muscle and bone health, according to the CSIRO report. Declining estrogen directly affects muscle protein synthesis — muscles become less responsive to the same protein stimulus, meaning you need more protein to achieve the same muscle-protective effect. At 70kg, that’s 70-84g per day, meaningfully higher than the official minimum.

Active women and those doing resistance training benefit from 1.2-1.6g/kg per day for muscle maintenance and recovery. At 70kg, that’s 84-112g — achievable through food without protein supplements.

Women over 70 have a higher official recommendation (1.0g/kg) because sarcopenia (age-related muscle loss) is a significant and recognised health risk after 70.

Where the influencer version goes wrong

The 130-150g daily targets popularised on social media are significantly above what research supports for most women, and Dietitians Australia’s caution is legitimate: very high protein intake — above 25% of total energy — is associated with crowding out other necessary nutrients (fibre, vegetables, wholegrains) and, for people with compromised kidney function, can increase metabolic stress.

The issue isn’t protein itself. It’s that "eat more protein" has been simplified into a universal prescription that ignores that most young, healthy, non-active women genuinely aren’t deficient.

The most useful way to think about it

Rather than counting grams against a target every day, the CSIRO report and broader research points to a more practical principle: aim for 25-30g of protein at each main meal, and distribute it across the day rather than loading it at dinner. This pattern consistently produces better muscle protein synthesis outcomes than the same total amount eaten in one or two sittings.

A typical breakfast with two eggs (12g), Greek yoghurt (10g), and some nuts (5g) gets you there at that meal without requiring a protein shake.

Practical food sources

The most efficient protein sources for women eating a varied diet: eggs (6g per egg), Greek yoghurt (15-18g per 200g), cottage cheese (12g per half cup), lentils (18g per cooked cup), tofu (8-10g per 100g), chicken breast (31g per 100g), canned tuna (25g per 100g), and edamame (8g per half cup).

You don’t need a protein powder to hit 25-30g at a meal. Most of the time, food is better, cheaper, and more satisfying.

FAQ

How much do women need?

0.75g/kg official minimum. 1.0-1.2g/kg for menopausal women and healthy ageing. 1.2-1.6g/kg for active women.

Do most women eat enough?

Enough to meet the minimum. Often not enough for optimal muscle health, especially over 40.

Best protein sources?

Eggs, Greek yoghurt, legumes, tofu, fish, chicken. Spread across meals.
