How Much Protein Do You Actually Need? The Number, and Where It Comes From

The UK reference nutrient intake for protein is 0.75g per kilogram of body weight per day for adults — which works out at about 45g a day for a 60kg woman and 52.5g for a 70kg woman. That figure is a minimum designed to prevent deficiency, not a performance target, and UK survey data suggests most adults are already comfortably above it.

Which makes this a slightly awkward article to write in 2026, because protein is having an enormous cultural moment. Supermarket shelves, coffee chains and half the internet are currently reorganising themselves around the word. So it is worth separating three different things: the official minimum, what people actually eat, and what might be worth changing as the autumn routine restarts.

The number, and how to work out yours

The UK guideline comes from the Department of Health and is quoted by the British Nutrition Foundation as 0.75g of protein per kilogram of body weight per day for adults.

The arithmetic is simply your weight in kilograms multiplied by 0.75:

• 55kg × 0.75 = 41.25g a day

• 60kg × 0.75 = 45g a day

• 70kg × 0.75 = 52.5g a day

• 80kg × 0.75 = 60g a day

The British Heart Foundation gives the same two worked examples: 45g a day for a 60kg woman and 55g a day for a 75kg man.

One important exception. The BHF notes that adults over 65 are advised to aim higher — 1g to 1.2g per kilogram of body weight per day — because protein needs change with age. For a 60kg woman over 65 that is 60–72g a day rather than 45g.

What people actually eat

Here is the part that rarely makes it into a protein post.

The National Diet and Nutrition Survey, quoted by the British Nutrition Foundation, puts average daily protein intake for UK adults aged 19–64 at 76.0g — around 85g for men and around 67g for women. For adults aged 65 and over the average is 67.0g.

Put those next to the guideline and the picture changes. A 60kg woman eating the female average of 67g a day is eating roughly 1.5 times the 45g reference intake. The typical problem in most UK diets is not that protein is absent. It is that it arrives in one lump at dinner and is nowhere to be seen at 7am or 4pm.

That is a distribution problem, not a deficiency problem, and it has a much cheaper fix than a shelf of powders.

Where protein actually comes from

Read that chart per 100g, not per portion — which matters, because a boiled egg weighs around 50g, so one egg gives you about half the 14.1g figure shown.

The British Heart Foundation puts some common portions in more useful terms:

• 100g of meat, fish or poultry — about 30g protein

• 150g of 0% Greek yoghurt — about 15g protein

• 200ml of milk — about 7g protein

• 1 egg — about 7g protein

• 100g of cooked lentils or beans — about 8g protein

Which means a 45g day is genuinely unremarkable: yoghurt at breakfast, beans or lentils at lunch, a normal portion of something at dinner, and you are there without buying anything with the word "protein" printed on the front.

The practical bit: three anchors, not a diet

If your protein all arrives at 7pm, the fix is to give it two more places to land. This is the whole intervention.

Anchor 1 — breakfast. Whatever you currently eat, add one protein-containing thing to it. Greek yoghurt alongside the toast. An egg with it. Milk instead of water in the oats. You are looking for roughly 15–20g, which is one small pot of yoghurt plus one egg.

Anchor 2 — the 4pm gap. The hour where the school run, the last hour of work and everyone's patience collide. This is the one that decides what dinner looks like, and it is almost always the one with no protein in it at all. A handful of almonds is about 21.1g per 100g, so a 30g handful is around 6g. Cheese, a boiled egg made that morning, or a yoghurt all do the same job.

Anchor 3 — dinner, unchanged. Genuinely. If dinner is already fine, leave it alone. Changing three meals at once is how autumn resets die by the second week of term.

Do the first anchor for a fortnight before adding the second. The point of a routine reset in September is that it survives to October.

What protein will not do

A short, honest list, because the current wave of marketing implies otherwise.

Protein is not a weight-loss mechanism in itself, and nothing in this article should be read as a promise about your body composition. It does not compensate for very little sleep, and September is often a very-little-sleep month. It is not a substitute for medical care, and if you are on any medication or under a doctor for anything, changes to what you eat are a conversation to have with them and not with an article.

And more is not automatically better. The reference intake is a floor rather than a ceiling, but stacking bars and shakes on top of an already-adequate diet is mostly an expensive way to eat the same amount of food.

This is general information, not medical advice. Speak to your GP or a registered dietitian if you are pregnant, managing a health condition, or have been advised to follow a specific diet.

Frequently Asked Questions

Q: How much protein does a woman need per day? A: The UK reference nutrient intake is 0.75g per kilogram of body weight per day for adults, so a 60kg woman needs about 45g and a 70kg woman about 52.5g. That figure is a minimum for preventing deficiency rather than an optimum. Adults over 65 are advised to aim higher, at 1g to 1.2g per kilogram, because protein needs increase with age.

Q: Am I already getting enough protein? A: Probably, on the survey evidence. The National Diet and Nutrition Survey puts average daily intake for UK adults aged 19–64 at 76.0g — roughly 67g for women and 85g for men — which is well above the 0.75g/kg reference intake for most body weights. The more common issue is timing: protein clustered at dinner and missing from breakfast and the late-afternoon gap.

Q: How much protein is in an egg? A: Around 7g in a single egg, according to the British Heart Foundation. Per 100g, whole boiled egg contains 14.1g of protein, and because a medium egg weighs roughly 50g the per-egg figure is about half that. Two eggs at breakfast therefore gets you to around 14g — a reasonable share of a 45g day before you have eaten anything else.

Q: What are good high-protein snacks that aren't protein bars? A: Almonds (21.1g per 100g, so about 6g in a 30g handful), cheddar (25.4g per 100g), a boiled egg made in advance, Greek yoghurt (around 15g per 150g pot), or cooked lentils and beans (around 8g per 100g). Health & Fitness with Ella keeps a free list of 60 of them for exactly the 4pm gap, because that is where most people's protein day falls apart.

Q: Do I need protein powder? A: Not to meet the reference intake — the figures above are reachable with ordinary food, and average UK intakes already exceed the guideline without supplements. Powder is a convenience product: useful if getting protein into a meal is genuinely difficult for you, unnecessary if it is not. It is worth pricing it against yoghurt, eggs and lentils before deciding.

Q: Does protein need to be spread through the day? A: For most people the practical benefit of spreading it is behavioural rather than metabolic — an afternoon with something substantial in it tends to produce a calmer approach to dinner. The evidence on optimal distribution is still debated and this article does not claim a settled answer. What is uncontroversial is that a day with protein only at 7pm has two long stretches with nothing in them.

Q: Do protein needs change after 65? A: Yes. The British Heart Foundation advises 1g to 1.2g per kilogram of body weight per day for adults over 65, compared with 0.75g/kg for younger adults — so 60–72g a day for someone weighing 60kg. Notably, the National Diet and Nutrition Survey average for the over-65 group is 67.0g, which sits at the lower end of that range rather than comfortably inside it.
