Protein After 50: Why Your Needs Shift and How to Eat for It
After 50, muscle becomes harder to build and easier to lose. Ageing muscle responds less strongly to the protein you eat, an effect researchers call anabolic resistance, so the same meal does a little less than it did at 30. The practical answer is to make sure every main meal contains a decent portion of protein, rather than saving most of it for dinner, and to pair that with regular strength training, which is what tells your muscles to use it. Many older adults eat enough protein in total but very little at breakfast and lunch. Fixing that distribution is usually the easiest win.
If you have kidney disease or another long-term condition, or have been given dietary advice by a doctor or dietitian, check with your GP before increasing your protein intake.
Why needs change with age
Muscle is lost gradually
From midlife onwards, muscle mass and strength tend to decline unless you do something to hold on to them. The process is gradual and easy to miss, because bodyweight can stay the same while muscle is replaced by fat. Over decades it affects how easily you climb stairs, carry shopping and get up from a low chair.
Muscle responds less to each meal
When you eat protein, your body uses the amino acids to repair and build muscle. In older adults, that response is blunted. In practice, a small amount of protein at a meal may not be enough to trigger much building at all, while a more generous portion will.
Appetite often falls
Many people eat less as they get older, and protein-rich foods are often the first to slip: a quick toast breakfast, a sandwich lunch. Total intake can drift down without anyone noticing.
How much protein do you need?
The UK reference figure for adults is 0.75g of protein per kilogram of bodyweight per day. That is a population baseline designed to prevent deficiency, not a target for keeping muscle while you train. An expert group (the PROT-AGE study group, writing in the Journal of the American Medical Directors Association in 2013) suggested that healthy older adults aim for around 1.0 to 1.2g per kilogram, and more for those who are active.
Rather than calculating grams, most people do well with a simpler rule: a palm-sized portion or more of a protein-rich food at each of three meals, plus a protein-containing snack if appetite allows. The Eatwell Guide remains a sensible frame for the rest of the plate.
Spread it across the day
A common pattern in the people I coach looks like this: toast and coffee for breakfast, a light lunch, then a large dinner with most of the day’s protein in one go. Moving some of that protein earlier tends to do more for muscle than adding more at dinner.
| Meal | Typical | Small upgrade |
|---|---|---|
| Breakfast | Toast and jam | Eggs on toast, or Greek yoghurt with oats and berries |
| Lunch | Soup and bread | Soup with added lentils, plus a tin of fish or cottage cheese |
| Snack | Biscuits | A glass of milk, a yoghurt or a handful of nuts |
| Dinner | Large meat portion | Normal portion; save the extra for breakfast |

Good protein sources that are easy to eat
- Eggs. Quick, cheap and soft enough for anyone who finds chewing harder.
- Greek yoghurt, skyr and cottage cheese. No cooking required.
- Milk. Easy to add to porridge, coffee or a smoothie.
- Tinned fish. Sardines, mackerel and salmon, which also provide oily fish the NHS recommends weekly.
- Chicken, turkey, lean beef and pork. Batch cook to save effort.
- Beans, lentils, tofu. Useful for plant-based eaters; combine sources across the day. Our guide to vegetarian protein sources covers how.
Protein powder can be convenient if appetite is low, but it is a supplement to food, not a replacement for it.
Protein without training does less
Eating more protein while staying sedentary will not rebuild muscle on its own. Strength training is the signal; protein is the material. The UK Chief Medical Officers recommend muscle-strengthening activity on at least two days a week for adults, and balance work for older adults, to reduce the risk of falls.
For most people over 50, two or three sessions a week built around squats or leg presses, a hinge such as the Romanian deadlift, pushes, pulls and carries will do the job, progressed gradually. Our workout plan for over-50s sets out a sensible weekly structure.
If you have a heart condition, joint problems, osteoporosis, or are returning after a long break, check with your GP first before starting a new programme.
When appetite is the problem
If you simply do not feel hungry enough to eat bigger portions, make protein denser rather than meals larger. Stir milk powder or Greek yoghurt into porridge, add an egg to soup as it simmers, swap a biscuit for a small pot of skyr, or choose a milky coffee over a black one. Small additions like these raise protein without making plates feel daunting. Chewing difficulties also matter: softer foods such as eggs, fish, mince, beans and dairy are easier than tough cuts of meat.
Mistakes worth avoiding
- Assuming you eat enough because dinner is generous. Look at breakfast and lunch.
- Cutting calories hard without protecting protein. Weight loss in later life should be gentle, with protein kept up, so you lose fat rather than muscle.
- Relying on shakes. Whole foods bring fibre, vitamins and minerals that a powder does not.
- Training too lightly. Muscles need a genuine challenge to keep growing, at any age.
How we work on this in the studio
In private personal training sessions in Highgate, we track muscle as well as weight. The InBody scanner gives an estimate of skeletal muscle mass, which lets us see whether a change in diet and training is protecting or building muscle over months. Nutrition advice stays practical and food-first; anything medical goes to your GP.
Questions we get asked
Is too much protein bad for older people?
For healthy people, eating moderately more protein from food is generally considered safe. If you have kidney disease or any long-term condition, ask your GP or a dietitian first.
Do I need protein shakes after 50?
No. They are convenient when appetite is poor or time is short, but food can do the job.
When is the best time to eat protein?
Spread across meals. Having some in the meal after a training session is sensible, but daily total and distribution matter most.
Can I still build muscle in my 60s and 70s?
Yes. People respond to well-planned strength training at any age. Prices and session details are on our personal training page.
