How Much Protein Do You Actually Need?
The standard recommendation was never designed for older adults. What the research actually says about how much protein, and when.
The number most people have heard is 0.8 grams per kilogram of body weight per day. That figure was never developed for older adults, and expert groups now consider it insufficient for them.
What the research recommends instead
Position papers from PROT-AGE and ESPEN recommend 1.0 to 1.2 g/kg per day for healthy older adults, and higher — 1.2 to 1.5 — with chronic illness or sarcopenia.
For a woman of 70kg, that's roughly 70 to 84 grams daily rather than 56.
The part that matters more than the daily total
Distribution. Older adults have a higher per-meal threshold before muscle protein synthesis is triggered — the research puts it at 25 to 30 grams per meal, containing around 2.5 to 2.8 grams of leucine.
Below that threshold, the protein is still used, but it doesn't switch on the muscle-building signal. So 60 grams eaten mostly at dinner does less than the same 60 grams spread evenly across three meals.
This is why the advice is protein at every meal rather than protein in general.
The finding that should change your breakfast
A study of 256 UK adults aged 65 to 89 compared actual intake against these recommendations. Fewer than half met even the older, lower national guideline. Fewer than 15% met the 1.2 g/kg age-specific one.
Exactly one participant hit 25 grams per meal across three meals. The researchers identified morning intake as the clearest opportunity.
If you take one thing from this article, take that.
What 25–30 grams looks like
- Three eggs plus a slice of cheese
- A cup of Greek yogurt plus a handful of nuts
- A scoop of protein powder in milk
- A chicken breast, roughly palm-sized
- A tin of tuna or salmon
- A cup of cottage cheese
- Lentils and quinoa together, in a generous portion
Breakfast is where most people fall short, and it's the meal where it costs the most.
One caveat
Higher protein intakes are well tolerated in older adults without significant kidney disease. With moderate-to-severe kidney impairment, protein targets are a clinical decision. If you have any kidney diagnosis, this is a conversation with your doctor rather than an article.
Try this week: measure your breakfast protein honestly for three days. Most people are surprised by how far under 25 grams they are.
Education, not medical advice — particularly with any kidney condition.
