Are You Eating the Right Amount of Protein for Your Age?

We’ll cut through the high-protein noise and help you find a sensible range for your age - and a calm way to check whether you’re in it.

Feb 21, 2026

Everywhere you look, the message is the same: add more protein. “High-protein” is stamped on yogurts, cereal, bread, ice cream and chocolate bars; fitness feeds talk about hitting your protein target; it’s easy to feel that whatever you’re eating now probably isn’t enough.

Hang around the health world for five minutes, and you start hearing “magic” numbers too: 0.8 g/kg is the minimum, 120 g a day is the secret to being lean forever, 1.6 g/kg is best for gains.

The deeper problem isn’t a lack of advice; it’s that those confident voices don’t agree - and the current craze for ever-higher protein is nudging a lot of younger and midlife adults into ranges that may be actively harmful over the long term. Just as the low-fat craze backfired, I think today’s “more protein for everyone” push is on track to do the same.

So, today we’ll answer the fundamental question:

“Given my age and how I eat, what kind of protein range should I be aiming for - and how can I tell whether I’m broadly on track?”

Today is deliberately a 30,000-foot view, not the final word on protein for every situation. We’ll get you a ballpark range that makes sense for your age, use a short check-up over a few typical days to see where you actually land, and work out whether your bigger risk is too little protein, too much, or the wrong kind. We’ll visit other protein-related topics in future issues.

Before we get into the facts, I’m really keen to understand how you think about your protein intake before we check anything.

As always, your answers are anonymous and they really help me ensure I write what’s most helpful to you. Please take a couple of seconds to check a box.

Let’s start with what people are already doing, before we add any “optimal” numbers.

Most under-65s aren’t short of protein

In Western countries, most people get 80-100g of protein a day.

That’s equivalent to 15-17% of daily calories and 1.0-1.3g per kg of body weight - already well above the recommended 0.8 g/kg minimum.

Once you start adding “high-protein” yogurts, bars and cereals on top of that, it’s very easy for younger and midlife adults to creep even higher without noticing.

More protein isn’t always better

When researchers look across big studies and ask, “Who tends to live the longest?”, they don’t see a straight line where more protein always equals better outcomes.

In a large studies, the lowest risk of dying early was in people getting about 14-18% of their daily calories from protein. That’s roughly 70-110 g of protein a day - not the 140-150 g/day targets that float around Instagram.

What’s more, there’s evidence that consuming lots more protein may be linked to worse health outcomes. Take a look at these graphs.

Two graphs showing that for adults under 65, higher protein consumption is linked to a higher risk of dying prematurely, while for those over 65, that link disappears, except for diabetes mortality. — The relationship between how much protein we eat and our risk of dying changes in our sixties (lower is better) | Data: Levine et al 2014 | Image: Author + Adobe stock

As the left-hand graph shows, for mid-life adults, high protein consumption is linked to higher rates of dying prematurely.

In other words, the current craze to chase ever-higher protein consumption may be costing lives.

However, once we get into our mid-sixties (right-hand graph), that risk goes away - except for dying from complications of diabetes (as diabetes is linked to impaired kidney function, and a high protein diet can make this worse).

Age changes the problem you’re trying to solve

Your body doesn’t handle protein in the same way at 30, 55 and 80.

In your twenties and thirties, your muscles are relatively responsive. Give them enough protein and a reason to use it (movement, strength work), and they’re happy.
By our seventies, many people’s muscles are much less responsive to the same protein dose. Appetite falls. Meals shrink. People slide into “tea and toast” patterns and lose muscle faster.

As a result, we lose muscle after our mid-fifties. In time, this can lead to frailty, falls, fractures and a loss of independence. It’s a big deal.

We have loads of studies on young and older adults (mostly male), but far fewer in between. So we don’t actually know the exact age when this change kicks in. It likely varies from person to person.

That said, most expert advice lands roughly here:

Younger adults (about 18-50):

For most healthy people, about 0.7-0.9 g/kg/day from real food looks sensible. Going much higher, especially when it’s from meat, cheese and high-protein junk, is probably risky for long-term health.

Transitional midlife (about 50-65):

This is the blurry zone. A sensible approach is to aim towards the top of that younger range - around 0.8-1.0 g/kg - and pair it with resistance exercise.

Older adults (~65-70+):

Here, the main threat isn’t “too much protein”; it’s too little, plus muscle loss and increased risk of falls.

For otherwise healthy older adults with decent kidney function, many experts now suggest aiming towards ~1.2 g/kg/day, alongside strength-building exercise, to protect muscle and independence.

Not all grams of protein are equal

Studies suggest that plant proteins tend to be associated with better long-term outcomes than the same grams from red and processed meat. Plant rather than animal protein is linked to lower risks of cardiovascular disease, type 2 diabetes and earlier death.In general:

Beans, lentils, chickpeas, peas, tofu, tempeh, edamame, peanuts, nuts, seeds and whole grains → good base layer of everyday protein
Yogurt, milk, cottage cheese and other dairy → important sources, but stick to lower-fat versions
Fish and modest amounts of poultry → reasonable for most
Processed meats (bacon, sausages, deli meats, pepperoni) → consistently associated with worse outcomes
“High-protein” UPF snacks → also associated with worse health outcomes.

For older adults with waning appetites, it matters less where protein comes from - just get enough. For younger and midlife adults, quality matters more, because you’re trying to protect heart, cancer and metabolic risk over decades.

Hold that picture in your head. Now let’s work out where you are on it.

A ten-minute protein check-up

Reading about 0.8 g/kg vs 1.2 g/kg is one thing. It’s hard to connect that to “porridge and yogurt for breakfast, beans on toast for lunch, fish and veg for dinner”.

So this week, I want you to take ten minutes to do a protein check-up.

Pick 2–3 typical days over the next couple of weeks. They don’t have to be in a row, but they should be ordinary days. If your weekends look very different from your weekdays, include at least one weekend day.
Write down every food and drink from that day, including snacks, nibbles and the “just one biscuit” moments. You’ll need to weigh or estimate the weight of what you eat.
Estimate the protein for each food. For each item, you want a rough idea of how many grams of protein it contains. You can use:

the table below,
food labels, or
an app/website that lists protein per 100 g.

You’re aiming for a “good enough” estimate, not scientific accuracy.

Add it up and convert to g/kg

Add all the protein grams up to get a daily total.
Divide that number by your bodyweight in kilograms.

If you weigh 70 kg and you estimate you ate 63 g of protein: g/kg = 63 ÷ 70 ≈ 0.9 g/kg

Write it down as a single, clear line, including your main sources. For example:

“Typical weekday: ~63 g protein, about 0.9 g/kg. Mostly from yogurt, chicken, cheese and a nightly protein bar.”

That one sentence is already far more useful than “I eat some protein, so I’m probably fine.”

Making sense of your number

Now you’ve got a g/kg figure. What does it actually mean?

The answer depends on your age and where your protein is coming from. The same number means different things in a 35-year-old lifting weights and a 78-year-old who’s lost their appetite.

Let’s walk through it in age bands.

If you’re under about 50

- If you’re around 0.7-1.0 g/kg, and most of that protein is coming from beans, lentils, tofu, nuts, seeds, yogurt and fish (with some poultry), you’re probably in a good place from a long-term health perspective. You don’t need to chase extra protein just because that’s what your social media feeds tells you.

If you’re below about 0.7 g/kg, especially if you’re active or trying to lose weight or build muscle, that’s likely on the low side. Add more protein from healthy sources.
If you’re at 1.3 g/kg or higher, and a big chunk of that is red and processed meat, cheese, eggs and protein-branded snacks, you’re in a pattern that’s linked to higher risks of cancer, type 2 diabetes and earlier death in large studies.

If you’re in your fifties or early sixties

This is the foggy zone in the data - lots of studies in people in their twenties and in their seventies, not much in between. A sensible interpretation looks like this:

If you’re consistently below about 0.7 g/kg and you’re not doing any resistance exercise, you’re probably under-feeding your muscles. You risk frailty and loss of independence as you get older.
If you’re somewhere around 0.8-1.0 g/kg, mostly from plants, fish and dairy, and you’re doing some strength work, you’re likely in a sensible band that balances muscle protection with long-term health.
If you’re at 1.3 g/kg or more, especially from lots of animal protein and high-protein ultra-processed foods, you’re in that red-zone pattern. It’s unlikely to be wise for long-term health unless you have a very specific medical reason and individual guidance.

If you’re in your mid-sixties or beyond

Here, the main problems are muscle loss, falls and losing independence, not squeezing your protein down in case it’s “too high”.

Lots of older adults end up around 0.6-0.8 g/kg without meaning to, simply because appetite shrinks and meals get smaller.

If you’re consistently below about 1.0 g/kg, you’re long term health and independence would likely benefit from increasing your protein consumption. At this age, the priority is getting enough total protein, then spreading it across meals, rather than chasing a perfect plant-heavy pattern. If, despite your best efforts, you can’t get up towards that 1.0–1.2 g/kg range, it’s worth talking to your doctor or a dietitian.

Two important catches:

Chronic kidney disease and diabetes are common and often silent in this age group.
More protein can cause problems if your kidneys are already struggling.

So if you’re in your seventies (or have kidney disease or diabetes at any age), have a chat with your doctor to make sure that lots of extra protein is the right move for you.

Whether your number came out low, middling or high, it’s not a badge of honour or shame; it’s a starting point. The goal now is simply to line your intake up with the range that makes sense for your age, without turning protein into another thing to obsess over. This week’s tweak is a simple way to do that.

HEALTH TWEAK OF THE WEEK: your quick protein audit

National diet surveys suggest many under-65s are already averaging 1.0-1.3 g/kg of protein a day, comfortably above the 0.8 g/kg minimum. Large studies suggest the lowest risk of early death sits around 14-18% of calories from protein, which for most people works out closer to 0.7-0.9 g/kg. So many of us may be getting more protein than is good for us.

At the same time, many older adults quietly slide down to 0.6-0.8 g/kg as appetite shrinks at a time when they actually need more protein, typically ~1.2g/kg to maintain muscle strength and independence.

This tweak is about getting a rough number for you, then making one age-appropriate adjustment.

So, this week’s tweak:

Find out how much protein you’re getting.
If it’s not in the right ballpark for someone your age, nudge it in the right direction.

1. Do the two or three-day protein check-up and write down your g/kg

If you haven’t done it yet, pick two or three genuinely typical days, list everything you eat and drink, estimate the protein for each food using the table or labels, add it up, and divide by your bodyweight in kg.

Write it down:

“Typical [weekday/weekend]: ~__ g protein, about __ g/kg. Main sources: __________.”

You’ve now got a baseline. No more guessing.

2. If you’re under ~65 and over ~1.3 g/kg, step out of the red zone

If your audit comes out above 1.3 g/kg, and most of that is from meat, cheese, eggs and “high-protein” snacks, treat that as a red flag, not a flex.

Over the next couple of weeks:

a. Set a lower ceiling.

Aim for a rough upper limit around 0.9–1.0 g/kg/day.

b. Trim one animal-heavy portion a day.

Halve the cheese, reduce the meat, or swap one meat-based meal for a bean, lentil or tofu dish.

c. Skip the protein-branded ultra-processed snacks.

Replace them with actual food: fruit plus nuts, yogurt plus seeds, or leftovers.

You’re not trying to become low-protein. You’re just getting out of a range that’s not helpful for long-term health, especially if your extra protein is mostly coming from meat, cheese and “high-protein” UPF.

3. If you’re 50-early 60s and under ~0.7 g/kg, nudge your protein up

If you’re in your fifties or early sixties and your number is below about 0.7 g/kg, you’re under-feeding your muscles, risking frailty and a loss of independence

This week, think about how you can boost your protein intake. Maybe:

add a proper portion of Greek yogurt and nuts,
double the beans or lentils in one main meal, or
add tofu or tempeh to a stir-fry you already like.

The goal isn’t to hit a perfect target in a week; it’s to start moving gently towards the 0.9–1.0 g/kg range that balances muscle protection with long-term health for this age group.

4. If you’re in your mid-sixties or beyond, be sure you’re getting enough protein

From the mid-sixties onwards, the main risks are muscle loss, falls and loss of independence, not “too much” protein.

If your audit is below about 1.0 g/kg, treat that as a nudge to increase.
Work towards 1.2 g/kg, spread across meals, using proteins you’ll actually eat: that might be beans and lentils, but it might also be dairy, fish, poultry or meat. At this stage, getting enough total protein and doing some kind of strength-building exercise probably matters more than having a perfectly plant-heavy plate.

If you have known kidney disease, diabetes, big protein swings aren’t ideal. Do the audit, then discuss it with your doctor or dietician with a very specific question:

“Given this, should I be eating more, less, or about this amount of protein - and what would you change first?”

That way, you’re using your number as a conversation starter, not a DIY prescription.

By the end of this, my hope is that protein feels less like a noisy argument on social media and more like something you quietly understand about your own body.

You’ll know the rough range that makes sense for you, whether you’re running low, sitting comfortably, or camping out at the very high end - and you’ll have one or two concrete changes underway.

Over the next few weeks, let that settle in. Then I’ll be back with the next part of this mini-series so we can build on it together - looking at how to spread protein through the day, how it links with strength, and when (if ever) a supplement is actually worth it.

Ignore the shouting; stick with me, and we’ll get your protein strategy sorted, step by step.
