Most women over 40 do well with around 1.2 to 1.6 grams of protein per kilogram of body weight per day, rather than only aiming for the basic minimum. So, if you weigh 70kg, a helpful daily target is often around 84 to 112g of protein, spread across your meals.
That is not a rigid rule, and it is not about eating huge portions of meat or drinking protein shakes all day. Your ideal amount depends on your weight, activity level, muscle mass, appetite, menopause stage, health history and goals. If you would like a personalised starting point, you can use my free protein calculator to estimate your daily and per-meal needs.
Why does protein matter more for women after 40?
Protein matters at every age, but it becomes especially important from your 40s onwards because your body composition, hormones and recovery can start to change.
Many women notice that what used to work for energy, weight balance and fitness simply does not work in the same way anymore. Some of this is linked with changing oestrogen levels during perimenopause and menopause. Some of it is linked with stress, sleep, blood sugar swings, reduced activity, and the gradual loss of muscle that can happen as we age.
Protein is one of the key nutrients that helps support:
- Maintenance of muscle mass
- Recovery after exercise
- Steadier appetite and fewer energy dips
- Healthy bones, alongside nutrients such as calcium, vitamin D and magnesium
- Immune function and tissue repair
- More satisfying meals, which can make healthy eating feel easier
This does not mean protein is a magic fix. It is one important part of the picture, alongside colourful plant foods, healthy fats, fibre, strength training, sleep and stress support. But for women over 40, getting enough protein is often one of the most practical nutrition upgrades you can make.
What is the basic protein recommendation?
In the UK, the general Reference Nutrient Intake for adults is commonly given as 0.75g of protein per kilogram of body weight per day. The British Dietetic Association explains that protein is needed for growth and repair, and that most people can meet their needs through food.
For a 70kg woman, that basic amount would be about 52g of protein per day. But here is the key point: that figure is a baseline for the general adult population. It is not necessarily the most supportive target for a woman over 40 who is active, strength training, managing appetite, navigating menopause, recovering from illness, or trying to preserve muscle while losing fat.
That is why I often see women do better with a more supportive range of 1.2 to 1.6g per kilogram of body weight. Some women may need less, and some may need more specialist guidance, particularly if they have a medical condition.
A simple protein target for women over 40
As a practical starting point, many women over 40 can use this range:
| Body weight | 1.2g/kg daily target | 1.6g/kg daily target |
|---|---|---|
| 55kg | 66g | 88g |
| 60kg | 72g | 96g |
| 65kg | 78g | 104g |
| 70kg | 84g | 112g |
| 75kg | 90g | 120g |
| 80kg | 96g | 128g |
| 90kg | 108g | 144g |
You do not have to hit the same number perfectly every day. Nutrition works best when it is realistic and consistent, not obsessive. Think of this as a gentle target range rather than a strict rule.
If you are very petite, mostly sedentary, or eating smaller portions due to appetite or digestion, the lower end may be more appropriate. If you lift weights, are very active, are working on fat loss, or find yourself hungry and tired between meals, the higher end may be more useful.
If you have kidney disease, liver disease, are undergoing cancer treatment, are recovering from surgery, or have been given specific medical advice about protein, please check with your GP, consultant or a suitably qualified practitioner before significantly changing your intake.
Do women need more protein during menopause?
Often, yes. Women may benefit from paying closer attention to protein during perimenopause and menopause because hormonal changes can affect muscle, bone, sleep, energy and fat distribution.
Oestrogen has a protective role in several tissues, including muscle and bone. As levels fluctuate and then decline, it can become harder to maintain muscle mass, especially if protein intake is low and strength training is not part of your routine. This does not mean menopause inevitably causes weight gain or loss of strength, but it does mean your nutrition strategy may need to evolve.
If this is relevant to you, I have written more specifically about whether women need more protein during menopause, including why it can make such a difference to midlife wellbeing.
How much protein should you eat at each meal?
For most women over 40, spreading protein through the day works better than saving most of it for dinner. A useful target is often 25 to 35g of protein per meal, with an optional protein-rich snack if needed.
This matters because your body can only make use of a certain amount of protein for muscle repair and maintenance at one time. You do not need to be perfect, but regularly eating a very low-protein breakfast, a light salad at lunch, and then one protein-heavy evening meal may leave you tired, snacky and under-fuelled earlier in the day.
Here are some approximate protein examples. Exact amounts vary by brand, portion size and preparation method.
| Food or meal component | Approximate protein |
|---|---|
| 2 large eggs | 12 to 14g |
| 200g Greek yoghurt | 18 to 22g |
| 150g cottage cheese | 18 to 20g |
| 120g cooked chicken or turkey | 30 to 35g |
| 120g cooked salmon | 25 to 30g |
| 150g tofu | 18 to 24g |
| 100g tempeh | 18 to 22g |
| 1 cup cooked lentils | 16 to 18g |
| 1 scoop protein powder | Usually 20 to 25g |
A good question to ask at each meal is: where is my protein coming from? If you cannot answer that easily, the meal may not keep you satisfied for long.
What are the best protein foods for women over 40?
The best protein foods are the ones you digest well, enjoy eating, and can realistically include most days. I always encourage a whole-foods approach first, with a mixture of animal and plant proteins if that suits your preferences.
Good options include eggs, fish, chicken, turkey, lean meat, Greek yoghurt, cottage cheese, kefir, beans, lentils, chickpeas, tofu, tempeh, edamame, nuts, seeds and good-quality protein powders when needed.
Try not to think of protein in isolation. A chicken breast gives you protein, but a balanced plate also needs fibre, colour and healthy fats. Lentils provide protein, but they also bring fibre and minerals. Oily fish such as salmon, sardines and mackerel provide protein plus omega-3 fats, which may support heart and brain health as part of an overall healthy diet.
If you eat a vegetarian or vegan diet, you can absolutely meet your protein needs, but you may need to be a little more intentional. Plant proteins can be very nourishing, but some are less protein-dense than animal proteins. That simply means portion sizes and combinations matter.
For example, soup made only with vegetables may be healthy, but it may not contain enough protein to sustain you. Add lentils, beans, tofu, tempeh, quinoa, seeds or a side of Greek yoghurt if you eat dairy. Small upgrades like this can make a meal feel completely different in terms of energy and fullness.
Do you need protein powder?
No, you do not need protein powder if you can meet your needs comfortably through food. However, it can be a very useful tool for women over 40 who struggle to eat enough protein at breakfast, after exercise, during busy working days, or when appetite is low.
A protein powder is not a replacement for a balanced diet. It is simply a convenient way to fill a gap. For example, adding a scoop to a smoothie with berries, ground flaxseed and unsweetened yoghurt can turn a light breakfast into something much more sustaining.
I personally use and recommend Form Protein Powder. This is an affiliate link, which means I may receive a small commission if you buy through it, at no extra cost to you. I only recommend products I genuinely use and feel comfortable suggesting to clients where appropriate.

How can you build a higher-protein day without counting everything?
You do not need to track every gram forever. Sometimes tracking for a few days can be helpful, simply to learn what your usual meals provide. After that, you can use patterns and portions.
Here is an example of how a woman might reach around 95 to 105g protein in a day:
| Meal | Example | Approximate protein |
|---|---|---|
| Breakfast | Greek yoghurt with berries, chia seeds and nuts | 25g |
| Lunch | Lentil and vegetable soup with chicken, tofu or cottage cheese on the side | 25 to 30g |
| Snack | Protein smoothie or boiled eggs with oatcakes | 15 to 25g |
| Dinner | Salmon, turkey, tofu or beans with vegetables and potatoes | 30g |
The exact foods can change depending on your preferences. The principle is the same: include a meaningful protein source at breakfast, lunch and dinner, then add a snack only if you need it.
One of the most common things I see with women over 40 is under-eating earlier in the day, then feeling ravenous or snacky by late afternoon. A more protein-rich breakfast and lunch can often make the whole day feel calmer.
What if you are trying to lose weight?
Protein can be particularly helpful if you are trying to lose weight in a sustainable way, because it supports fullness and helps protect muscle while you reduce body fat. This matters because muscle is metabolically active tissue, meaning it plays a role in how your body uses energy.
However, more protein does not mean more restriction. In fact, many women over 40 have spent years dieting, cutting calories, skipping meals and trying to be good. That approach can backfire, especially when stress, sleep disruption and hormonal changes are already affecting appetite and energy.
A better approach is to build meals that are satisfying, nourishing and steadying. Protein helps, but so do fibre-rich carbohydrates, colourful vegetables, healthy fats and regular meals. If weight management is your goal, the question is not just how little can I eat? It is how can I nourish my body in a way I can actually maintain?
Can you eat too much protein?
Yes, it is possible to overdo protein, especially if it crowds out other important foods. A diet that is high in protein but low in fibre, vegetables, fruit, whole grains and healthy fats is not balanced.
For most healthy women, a moderate increase in protein from whole foods is generally well tolerated. But if you have kidney disease, reduced kidney function, a complex medical history, or you have been advised to limit protein, you need personalised guidance.
It is also worth remembering that digestion matters. Suddenly doubling your protein, especially from powders or large portions of meat, may leave you feeling bloated or uncomfortable. Increase gradually, chew well, include plenty of fluids, and keep fibre in the picture.
Frequently Asked Questions
Is 100g of protein too much for a woman over 40? For many women over 40, 100g of protein per day is a reasonable and supportive amount, especially if they weigh around 65 to 80kg, exercise regularly, or want to maintain muscle. It may not be right for everyone, particularly with kidney issues or specific medical advice, so individual context matters.
Should women over 40 eat protein at breakfast? Yes, it is usually a good idea. A protein-rich breakfast may help support steadier energy, reduce mid-morning cravings and make it easier to reach your daily target without relying on a very large evening meal.
Can I get enough protein without eating meat? Yes, but you may need to plan more intentionally. Include foods such as tofu, tempeh, lentils, beans, edamame, Greek yoghurt, cottage cheese, eggs, nuts, seeds and protein powder if useful.
Is protein powder safe for women over 40? For most healthy women, a good-quality protein powder can be a convenient way to top up intake. Choose one with simple ingredients, check it suits your digestion, and speak with a healthcare professional if you have a medical condition or take prescribed medication.
How quickly will I notice a difference from eating more protein? Some women notice better fullness and steadier energy within days. Changes in strength, body composition and muscle maintenance take longer and are best supported by consistent protein intake, strength training, sleep and overall balanced nutrition.
Would you like help finding your ideal protein target?
Protein for women over 40 does not need to be complicated, but it does need to be personal. Your best target depends on your body, your health, your lifestyle and what you want to feel better in.
