Protein is having a moment.
It’s on every menu, in every supplement, on the packaging of things that had absolutely no business advertising their protein content until approximately three years ago. Protein water. Protein pasta. Protein cereal. High-protein, extra-protein, now-with-added-protein.
And I understand if it feels like noise.
Another wellness trend. Another number to optimise. Another thing to feel vaguely guilty about not doing correctly.
But I want to offer you a different frame.
Because unlike a lot of what cycles through the wellness space, the detoxes, the elimination protocols, the fasting windows, the protein conversation is one that is genuinely supported by the evidence. Particularly for women over 40. Particularly now.
Not for the reasons the marketing leads with. But for reasons that have everything to do with your hormones, your muscle, your energy, and the quality of your life in the decades ahead.
Why Your Body’s Relationship With Protein Changes After 40
There is a process that begins to take hold in your 40s called anabolic resistance. It means the body becomes progressively less efficient at converting dietary protein into muscle tissue. The signal that 20 grams of protein would have sent to your muscles at 30 simply doesn’t land with the same force at 50.
Declining oestrogen compounds this. Oestrogen plays a direct role in muscle protein synthesis, it supports the body’s ability to build and repair muscle. As levels drop through perimenopause and post-menopause, that support diminishes. The body’s natural muscle-building environment becomes less receptive.
The result is that without a conscious increase in protein intake, muscle loss accelerates quietly, without fanfare, often misread as weight gain or slowing metabolism or simply “getting older.”
And the standard protein recommendation most of us grew up with, 0.8 grams per kilogram of body weight per day, was designed to prevent deficiency in sedentary adults. It was never intended to support an active woman navigating hormonal change.
Research published in the Journal of the American Medical Directors Association and supported by multiple large-scale analyses confirms this clearly: women in midlife need significantly more protein than general guidelines suggest, not as an indulgence or an optimisation hack, but as a baseline requirement for maintaining the body they have and building the one they want.
What Women At Each Hormonal Stage Actually Need
These are the targets I work with inside the Strong Calm Lean Method:
Women 40–55 (Perimenopause)
- Daily target: 2.0–2.3g of protein per kilogram of body weight
- For a 65kg woman: 130–150g of protein daily
- For a 75kg woman: 150–172g of protein daily
- Post-workout: 40–50g within 45 minutes of strength training
Women 55+ (Post-Menopause)
- Daily target: 2.2–2.4g of protein per kilogram of body weight
- For a 65kg woman: 143–156g of protein daily
- For a 75kg woman: 165–180g of protein daily
- Post-workout: 40–60g within 45 minutes
These numbers will likely be higher than anything you’ve been told before. That is not because the science is new; it’s because the science as it applies to women in midlife has been consistently under-communicated.
How To Spread Protein Across Your Day
Meeting your daily target becomes far more manageable when protein is distributed across meals rather than concentrated in one. Research supports 30 to 40 grams per meal as the range that best stimulates muscle protein synthesis, closer to 40 to 50 grams if you are over 50.
A framework that works for most women:
- Breakfast: 30–40g eggs, Greek yoghurt, cottage cheese, or a protein smoothie with Whey Protein Isolate
- Lunch: 30–40g grilled chicken or salmon, legumes with a complete protein source
- Post-workout (if training in the afternoon): 40–50g within 45 minutes
- Dinner: 40–50g
Useful reference points: grilled chicken breast provides around 40g per 135g serve; three eggs approximately 19g; 200g Greek yoghurt around 17g; 200g cottage cheese approximately 24g; one cup of cooked lentils around 18g; and a serve of whey protein isolate approximately 25g, a practical tool on training days.
The Strong Calm Lean Approach To Lower Body Training
Protein isn’t a trend. It isn’t a biohacker’s obsession. It’s the raw material your body uses to build and repair the muscle that carries you through your life.
And yes, everyone is talking about it right now. But for women in their 40s, 50s and 60s, the conversation is more relevant than it has ever been. Because the window to build and protect muscle is not infinite. And the tools available to you – strength training, adequate protein, good sleep, nervous system regulation work best when used together.
Getting your protein right isn’t about perfection. It’s about understanding what your body actually needs, and making one or two consistent changes that move the needle.
