Why Protein Matters More After 40
As women enter their 40s and beyond, the body begins to change in subtle but important ways. Muscle mass gradually declines, bone density may decrease, and metabolism often slows. Hormonal shifts during perimenopause and menopause can also affect energy levels, weight distribution, and strength.
Protein plays a critical role during this stage of life. It supports muscle maintenance, helps preserve bone strength, and contributes to metabolic health. Yet many women continue to eat the same way they did in their 20s and 30s, often without realising that their protein needs may have increased.
Muscle Loss and Strength: Why Protein Is Key
Wellness starts with simple habits — a stretch, a breath, a moment for yourself.
From midlife onwards, women naturally lose muscle mass each year if no action is taken. This loss can affect balance, posture, and physical resilience, increasing the risk of falls and injury later in life.
Adequate protein intake helps slow this decline by supporting muscle repair and strength, especially when paired with regular movement or resistance exercise. Including protein consistently throughout the day — rather than only at dinner — is more effective for maintaining muscle health.
Protein and Bone Health Are Closely Linked
Bone health is often associated with calcium, but protein is just as important. Protein helps maintain bone structure and supports the absorption of minerals that keep bones strong. Insufficient protein intake has been linked to reduced bone density and higher fracture risk in older women.
For women 40+, ensuring enough protein alongside calcium- and vitamin D–rich foods support long-term skeletal health.
Metabolism, Weight Changes, and Protein
Metabolism, Weight Changes and Protein
Hormonal changes can make weight management more challenging during midlife. Protein helps by increasing satiety, stabilising blood sugar, and reducing muscle loss — all of which support a healthier metabolism.
Meals that include adequate protein are more satisfying and may reduce mindless snacking or energy crashes later in the day.
Best Protein Choices for Women 40+
There is no single “perfect” protein source. Instead, variety matters.
Animal protein such as fish, eggs, chicken, and dairy provides complete amino acids and nutrients like vitamin B12 and iron, which are especially important for women. Plant protein from tofu, tempeh, beans, lentils, nuts, and seeds adds fibre and supports heart and gut health.
A combination of plant and animal protein often offers the best balance, providing nutritional coverage without relying too heavily on any one source.

While needs vary based on activity level and health status, many women benefit from spreading protein intake evenly across meals. Including a moderate portion of protein at breakfast, lunch, and dinner helps support muscle maintenance and steady energy levels.
Women who are physically active, strength training, or experiencing muscle weakness may benefit from slightly higher protein intake, ideally discussed with a healthcare professional.
Making Protein Work in Everyday Life
Incorporating protein does not require drastic diet changes. Simple habits can make a difference, such as adding eggs or yoghurt at breakfast, choosing fish or tofu for lunch, and including legumes or lean meat at dinner.
In a Singaporean context, common meals like fish soup, tofu dishes, eggs in stir-fries, and seafood-based meals already provide good protein options. Small adjustments — such as prioritising protein first on the plate — can help ensure adequate intake.
Protein, Ageing, and Long-Term Health
Protein is not just about strength or weight. It supports immunity, recovery from illness, and overall vitality. For women navigating midlife and beyond, consistent protein intake is one of the most effective — and often overlooked — tools for ageing well.

Conclusion
For women 40+, protein plays a vital role in supporting strength, bone health, and metabolism. Rather than focusing on restrictive diets or extremes, a balanced approach that includes a variety of protein sources is more sustainable and effective. By paying attention to protein choices and consistency, women can better support their health, resilience, and quality of life through midlife and beyond. PRIME
