How much protein per day makes sense?

The official minimum recommendation is around 0.8 grams per kilogram of body weight – it prevents deficiency but isn't an optimum. For strength training, cutting phases and people over about 60, the data points to 1.2 to 1.6 grams, up to around 2 grams for intensive muscle building. Beyond that, no additional benefit is proven – extra protein is simply metabolised, not turned into extra muscle.

Do I need protein powder?

No – it's a tool, not a must: a practical, affordable protein source for anyone who struggles to hit their target through meals alone. If you already reach your amount with quark, pulses, fish, eggs, tofu and meat, powder gains you nothing. It only becomes an issue when protein-marketing products (bars, snacks) are ultra-processed calorie bombs with a protein fig leaf – a glance at the ingredients list gives that away.

Is too much protein harmful to the kidneys?

For healthy people with no existing kidney condition, the evidence shows no kidney damage even at higher protein intake (up to around 2 grams per kilogram). For already impaired kidney function, the picture is different – here, too much protein can put additional strain on the kidneys, which is why a protein amount agreed with a doctor matters. The blanket myth that “lots of protein always damages the kidneys” isn't backed up for healthy people, but for kidney patients it's genuinely worth discussing with a doctor.

Is plant protein worse than animal protein?

Animal protein usually delivers a more complete amino acid profile in a single serving, but the difference is easy to balance out over the day: combine different plant sources – pulses with grains, for example – and you reach a similarly complete profile. More important than plant versus animal is the total amount across the day and a certain variety of sources. A purely plant-based diet just requires a bit more planning, not a fundamental sacrifice of adequate protein.

Should protein be spread across the day or eaten all at once?

Spread out clearly wins: the body can only use a limited amount of protein per meal for muscle building, roughly 25 to 40 grams, depending on body size and age. Eat your entire daily amount in one evening meal, and you give away part of the benefit compared with spreading it across three to four meals. This distribution matters especially for older people, whose bodies need a larger portion per meal anyway to trigger the same muscle response.

The Protein Hype: How Much You Really Need

Protein bread, protein-maxxing: protein has become a marketing label. How much protein you really need – and where the hype parts ways with the evidence.

Protein has achieved what every nutrient dreams of: it’s become a selling point. Protein bread, protein ice cream, protein cornflakes – and on social media, “protein-maxxing”, maximising intake at every opportunity. As is usually true with hype: the core is justified, the exaggeration isn’t. Time for the sober maths.

Key takeaways

The minimum recommendation of 0.8 grams per kilogram prevents deficiency but isn’t an optimum for people who train or are older.
1.2 to 1.6 grams per kilogram is considered the sensible target range for strength training, cutting phases and people over about 60.
Beyond roughly 1.6 to 2 grams per kilogram, the benefit clearly plateaus, even for athletes.
Protein powder is a practical tool, not a necessary supplement – real food is enough for most people.
Many “protein” products are ultra-processed foods with a protein fig leaf, not an automatic health signal.

Where the hype actually comes from

Protein marketing isn’t an accident, it’s a logical response to a genuine trend: more and more people train strength, more and more people focus on satiety instead of pure calorie counting, and both groups deliberately seek out protein. The food industry has spotted this demand and now slaps “protein” labels on products that used to carry no health promise at all – from yoghurt to breakfast cereal. The result is a market logic in which a single nutrient becomes the selling point, regardless of the rest of the composition. That’s exactly why the same second glance is worth applying to every “protein” label: what else is on the ingredients list, and would the product be a sensible choice even without the protein print?

What the hype gets right

Protein really is the most underrated macronutrient in everyday eating. It’s the most satiating, costs the body the most energy to process, and is the building material for the organ that helps decide healthy ageing: muscle. Three groups demonstrably benefit from more than the minimum recommendation: anyone who strength trains (building material for adaptation), anyone cutting weight (protecting muscle mass in a deficit, better satiety), and older people – the ageing body responds more sluggishly to protein (anabolic resistance) and needs larger portions per meal for the same muscle preservation. Practically proven: spread protein across the day, roughly 25 to 40 grams per main meal, instead of everything in the evening.

Calculating your protein needs: a simple worked example

You can estimate your own needs in three steps:

Establish your body weight – as the starting value.
Choose a target factor – 0.8 g/kg as the minimum, 1.2–1.6 g/kg for training or an age over 60, up to 2 g/kg for intensive muscle building.
Multiply – body weight times target factor gives the daily amount in grams.

Concretely: someone weighing 70 kilograms reaches 56 grams of protein daily at the minimum recommendation – roughly equivalent to two or three eggs, a serving of quark and a small serving of pulses. Strength train regularly and raise the same target factor to 1.4 grams, and you land at 98 grams daily – already noticeably more planning effort, but achievable with three to four protein-rich meals, even without powder.

Protein sources compared

A rough overview of common everyday sources, their protein content and practical suitability:

Source	Protein per 100 g	Practical note
Quark (low-fat curd cheese)	approx. 12 g	affordable, versatile, filling
Lentils (cooked)	approx. 9 g	plant-based, high in fibre
Chicken breast	approx. 23 g	lean animal protein
Tofu	approx. 12–16 g	plant-based, versatile to use
Eggs	approx. 13 g (per 100 g)	complete amino acid profile
Protein powder (whey/plant)	approx. 70–80 g	convenient, but no must

The table shows why powder is often overrated: a normal everyday meal with quark, pulses or lean meat often already delivers most of what an extra serving of powder provides per portion – just without the marketing markup.

Where the hype parts ways with the evidence

The limits are just as clear. More isn’t linearly better: beyond roughly 1.6 to 2 grams per kilogram, the benefit plateaus even for athletes – the surplus becomes energy, not muscle. “Contains protein” doesn’t mean healthy: many protein products are classic ultra-processed foods with a health promise printed on top – expensive sugar with added protein is still expensive sugar (more in the article on ultra-processed foods). And when US recommendations were recently revised sharply upward, nutrition scientists, including from Stanford, dryly noted that no new evidence supported such a doubling. So scepticism is warranted even towards official figures – in both directions.

The most common mistakes with protein consumption

Mistake 1: Never calculating your needs. Without a rough target figure, estimates are almost always off – usually too low for people who train, sometimes needlessly high for desk jobs without training. Mistake 2: Eating it all in the evening. The body can only use a limited amount of protein per meal for muscle building – spreading it across the day is more effective than one large portion. Mistake 3: Confusing the protein label with health. A glance at the rest of the ingredients list often reveals sugar, fat and additives behind the big “protein” print. Mistake 4: Relying only on powder. Replace real food entirely with powder, and you lose the fibre, micronutrients and satiety that whole food provides. Mistake 5: Under-supplying older family members. In old age especially, the increased need is often overlooked, even though it’s most important there for preserving muscle.

When protein powder is genuinely worth it

Powder is neither a miracle cure nor superfluous – the answer depends on your daily life:

Worth it: right after training when there’s little time for a proper meal; for busy people who otherwise regularly miss their target amount; as a simple way to supplement a plant-based diet with a concentrated protein source.
More optional: when the daily amount is comfortably reached through meals anyway; as a substitute for a whole meal in everyday life, where fibre and micronutrients would be missing; with marketing products that use powder only as an additive to otherwise ultra-processed snacks.

The simplest rule of thumb: powder is a time-saving tool, not a substitute for a balanced diet – keep the two clearly separate, and you make the buying decision without marketing noise.

The everyday translation

For most people, the answer is: more protein quality, less protein marketing. Estimate your needs honestly once (body weight times target factor), build the base from real food – pulses, dairy, eggs, fish, meat in moderation, tofu – and treat powder as a gap-filler, not a lifestyle. The plant-based share can happily grow here: alongside protein, it delivers what protein products almost always lack – fibre and the rest of real nutrition.

The bottom line

Protein deserves its good reputation, but not the marketing escalation currently happening around it. Work out your target amount roughly once, spread it across the day and cover it primarily from real food, and you’ve already realised the benefit – every further gram beyond about 1.6 per kilogram is reassurance, not additional effect. The most sensible next step is rarely a new product on the supermarket shelf, but an honest look at your own plate.
