How Many Calories Should a Woman Over 50 Eat in Australia?
Calorie needs change significantly for women after 50. Metabolism slows by approximately 5–8% per decade from age 40, and the hormonal shifts of perimenopause and menopause accelerate fat storage — particularly around the abdomen — while muscle mass declines at roughly 1% per year without resistance training.
The result: many women find they gain weight eating the same amount they always have. Understanding your actual calorie needs — and adjusting protein intake upward to protect muscle — is the foundation of healthy weight management after 50.
Average Calorie Needs for Australian Women Over 50
| Age & Activity | Maintenance Calories | Weight Loss Target |
|---|---|---|
| 50–55, sedentary | 1,650–1,750 cal | 1,150–1,250 cal |
| 50–55, moderately active | 1,900–2,050 cal | 1,400–1,550 cal |
| 55–65, sedentary | 1,550–1,700 cal | 1,050–1,200 cal |
| 55–65, moderately active | 1,800–1,950 cal | 1,300–1,450 cal |
| 65+, lightly active | 1,600–1,750 cal | 1,100–1,250 cal |
Why Protein Is Critical After 50
Women over 50 need significantly more protein than younger women to maintain muscle mass — approximately 1.2–1.6g per kg of body weight per day (compared to 0.8g/kg for general adults). This is because the anabolic response to protein becomes less efficient with age, a phenomenon called anabolic resistance.
Practical targets: a 65kg woman over 50 should aim for 78–104g of protein daily, spread across meals. Good Australian protein sources include eggs, Greek yoghurt, legumes, fish, chicken, and tofu.
Menopause and Metabolism
Oestrogen decline during and after menopause reduces metabolic rate and promotes fat redistribution to the abdomen. Resistance training (2–3 sessions per week) is the single most effective intervention — it preserves muscle, supports bone density, and maintains metabolic rate better than cardio alone.
