Protein for Female Athletes: How Much, and When
“I’m trying to up my protein but I’ve no idea if I’m anywhere near enough.” If that is you, you are in very good company. Most of the women I coach are undershooting, often by a lot.
Protein is having a moment, and for once the hype is earned. It is the nutrient that lets you hold onto muscle, recover between sessions, protect your bones and stay strong through every life stage. And yet it is the single most common gap I see on a female athlete’s plate.
This is the honest, practical version. How much you actually need, when to eat it, where to get it, and why women in particular tend to fall short. No powders required, though they can help. Just enough, spread properly, most days.
For women training regularly, the evidence points to roughly 1.6 to 2.2 grams of protein per kilogram of body weight per day. For a 65kg woman that is around 105 to 145g a day.
The government minimum you might have heard, closer to 0.75g per kg, is set to stop a sedentary person becoming deficient. It is not a performance target for someone who runs, rides and lifts. If you are training hard and eating like a non-athlete, you are under-fuelling your recovery without realising.
That gap matters more for women than it used to be assumed. Emerging female-specific research suggests women may benefit from being at the higher end of that range, especially around their period and through perimenopause, when the body holds onto muscle less easily.
Why Women Undershoot
It is rarely laziness. It is a mix of habit, history and messaging. Worth naming so you can spot it in yourself.
Toast, cereal, a banana, a coffee. Lovely, but often almost no protein, which means you start the day behind and never catch up.
Fix: build protein into breakfast. Eggs, Greek yoghurt, a protein shake in your porridge. This one change moves the needle more than any other.
Diet culture taught a lot of women to fear big portions and treat protein as something calorie-dense to minimise. Old habits linger even once you are training seriously.
Fix: reframe protein as performance fuel, not a calorie cost. You are an athlete now. Eat like one.
Barely any protein all day, then a big chicken dinner. Your body cannot use a huge single hit as well as it uses protein spread across the day.
Fix: spread it. A good dose at each meal beats one big one at night.

Total daily protein is the big lever. Timing is the fine-tuning on top. Both are easy once you know the shape.
Aim for a solid dose of protein at each meal rather than saving it all up.
- Roughly 0.3g per kg of body weight per meal is a good target. For a 65kg woman that is around 20g, and up to 30 to 40g works well too.
- Three meals at that level, plus a protein-containing snack or two, gets most women to their daily total without trying.
- Include a protein source at breakfast. It is the meal where women lose the most ground.
The old “30-minute window” was oversold, but getting protein in after a session still helps recovery.
- Have a protein-containing meal or snack within a couple of hours of finishing a hard or long session.
- Pair it with carbohydrate to refuel and recover together. A smoothie with yoghurt, milk, fruit and oats is perfect.
- If you train fasted first thing, do not then skip breakfast. Get protein and carbs in soon after.
- A slower-digesting protein like Greek yoghurt, cottage cheese or milk before bed can support overnight recovery.
- Handy if you struggle to hit your total during the day, or if you train in the evening.
Where to Get It
You do not need to live on chicken and protein powder. Variety keeps it enjoyable and sustainable. Rough protein amounts, so you can see how it stacks up.
- Two eggs: around 12g.
- A chicken breast: around 30 to 40g.
- A tin of tuna: around 25g.
- A 150g pot of Greek yoghurt: around 15g.
- A palm of tofu or tempeh: around 15 to 20g.
- A tin of chickpeas or lentils: around 15g across the tin.
- A scoop of protein powder: around 20 to 25g.
You can absolutely hit your target on a plant-based diet. It just takes a little more attention, because plant proteins are less concentrated and you may want to combine sources across the day. Beans, lentils, tofu, tempeh, edamame, soya milk and a good vegan protein powder all pull their weight.
Do You Need a Protein Shake?
No, not necessarily. Whole food first, always. But a protein shake is a genuinely useful tool, not a cop-out, when real food is not practical. Straight after an early session before work. On a busy day when you are miles behind. As an easy way to make breakfast count. Think of powder as a convenient top-up, not a magic ingredient. If whole food gets you to your target, you do not need it at all.
Protein and Your Life Stage
Your protein needs are not fixed across your life. Two moments are worth flagging.
Through perimenopause and menopause, falling oestrogen makes it harder to build and hold muscle, so sitting at the higher end of the range, around 2g per kg, becomes more important. I cover the whole picture in my perimenopause training guide. And if you are pregnant or postpartum, your needs change again, so that is worth individual advice rather than a generic number.
The through-line across every stage is the same. Protein is not optional, it is not fattening, and most women need more of it than they are getting. Get it up and you recover better, hold your strength, and feel the difference within weeks.
Protein and Body Composition
A lot of women first hear about protein in the context of losing weight, so let me address that head on, because the truth is more encouraging than the diet-industry version.
Protein helps with body composition in ways that have nothing to do with eating less. It is the most filling of the three macronutrients, so a protein-rich meal keeps you satisfied for longer and takes the edge off the 4pm biscuit-tin raid. It also has a higher thermic effect, meaning your body burns a little more just digesting it. Most importantly, when protein is adequate and you are strength training, your body is far better able to hold onto muscle, and muscle is what keeps you strong, capable and metabolically healthy for life.
So the goal is not to eat less and shrink. It is to eat enough protein, train, and let your body become stronger and more resilient. If a change in body composition is something you want, adequate protein makes that process healthier and more sustainable. If it is not, adequate protein still makes you a better-fuelled, better-recovered athlete. Either way, more protein, not less food, is the move. I cover the whole fuelling picture, including why under-eating backfires, in my guide to under-eating and fuelling properly.
Three Protein Myths Worth Binning
In healthy people, higher-protein diets within sensible athletic ranges have a strong safety record. The kidney worry applies to people with existing kidney disease, who should get individual advice. For a healthy active woman, hitting your target is safe.
The old idea that anything over about 20g is wasted is outdated. Your body can use more from a larger meal, it just uses it a bit more slowly. Bigger doses at some meals are completely fine. Spreading it out is about convenience and appetite, not a hard limit.
Endurance athletes need plenty of protein too, to repair the muscle damage of all that running and riding and to hold onto lean tissue. It is not a gym-bro nutrient. It is an everyone-who-trains nutrient.
A Simple Day That Hits the Target
To show how achievable this is, here is a straightforward day for a 65kg woman aiming for around 120g. Nothing fancy, no powders required.
- Breakfast: Greek yoghurt with berries, oats and a spoon of nut butter, or two eggs on toast. Around 20 to 25g.
- Lunch: a chicken, tuna, tofu or egg-based lunch with plenty of carbs and veg. Around 30 to 35g.
- Snack: a pot of yoghurt, a glass of milk, or a handful of edamame. Around 15g.
- Dinner: a palm or two of your protein of choice with rice or potatoes and veg. Around 35 to 40g.
- Optional before bed: a small yoghurt or milky drink. Around 10 to 15g.
Add it up and you are comfortably at your target, without a single scoop of powder or any calorie counting. It really is that doable once you build it in as a habit.
Getting Enough on a Plant-Based Diet
If you are vegetarian or vegan, you can absolutely hit your protein target as an athlete. It just takes a bit more intention, because plant proteins tend to be less concentrated and slightly less well absorbed than animal sources. A few practical pointers make it straightforward.
- Lean on the denser sources: tofu, tempeh, edamame, seitan, lentils, beans, chickpeas and soya milk and yoghurt.
- Because plant sources are less concentrated, you may need slightly larger portions to hit the same grams. That is normal, not a failing.
- Eat a variety across the day so you cover the full range of amino acids your muscles use to repair.
- A good vegan protein powder, soya or pea based, is a genuinely useful tool for topping up, especially post-training.
- Aim towards the higher end of the protein range to account for the slightly lower absorption.
Plenty of strong endurance athletes eat entirely plant-based and thrive. The principle does not change. Enough total protein, spread across the day, from sources you enjoy and will actually eat.
Start With One Change
If your protein is currently all over the place, do not try to overhaul everything at once. Pick the meal where you are weakest, almost always breakfast, and fix that one first. Add eggs, Greek yoghurt, or a scoop of protein in your porridge, and leave the rest of your day as it is for a week or two. Once that is a habit, look at your snacks, then your lunch. Small, stacked changes stick. A dramatic overhaul you abandon after a fortnight does nothing. This is a long game, and the women who win it are the ones who change one thing, make it automatic, then move to the next.
The Short Version
Active women need roughly 1.6 to 2.2g of protein per kg of body weight per day. Most are undershooting.
Spread it across the day, around 20 to 40g per meal, rather than loading it all into dinner.
Build protein into breakfast. It is where women lose the most ground.
Get protein plus carbs in within a couple of hours after hard or long sessions.
Whole food first. Powder is a useful top-up when real food is not practical.
Aim higher, nearer 2g per kg, through perimenopause and menopause.
Strong, fed and glowing beats small, hungry and depleted. Every time. Eat the protein.
