Protein requirements by age are easiest to see on a plate. In Dutch food records, older people ate 10 to 12 grams at breakfast, 15 to 23 at lunch and 24 to 31 at dinner, and those living at home averaged 71 a day. At 70 kilograms (154 pounds), 1.0 to 1.2 grams per kilogram is 70 to 84 grams. The answer first: from 65, at least 1.0 to 1.2 grams per kilogram a day, 1.2 to about 1.6 with strength training, and about 25 to 35 grams per meal. In trials, more protein added muscle only with strength training.
Key takeaways
1. Protein requirements by age: DGE 0.8 g/kg under 65, 1.0 from 65; geriatric experts 1.0 to 1.2; US 1.2 to 1.6. At 70 kg, 1.0 to 1.2 means 70 to 84 grams a day.
2. Per meal: about 0.4 g/kg in lab data from older men, 24 to 36 grams at 60 to 90 kg, reachable without powder.
3. Spreading: in trials, spread and timing showed no measurable muscle effect. Breakfast ran lowest in food records.
4. Muscle: in 28 trials, more protein added muscle only alongside strength training.
5. Powder and kidneys: powder only when food falls short; healthy kidneys showed no consistent harm in short trials.
How much protein do you need at 50, 60 and 70?
It depends on your weight and whose number you use. Germany's nutrition society (DGE) sets 0.8 grams under 65 and an estimated 1.0 from 65, per kilogram of body weight a day. European geriatric experts (PROT-AGE) advise at least 1.0 to 1.2 from 65, and at least 1.2 for active people. The US Dietary Guidelines 2025 to 2030 set a goal of 1.2 to 1.6 for every adult.
At 50 or 60, the US goal applies; the German value stays 0.8 until 65, where the geriatric numbers start. Europe's clinical nutrition society, ESPEN, also names at least 1.0 to 1.2 grams for healthy older people.
Grams per kilogram means daily grams of protein for each kilogram of healthy body weight. Your row is in the table; the protein calculator for your weight does the exact sum.

| 90 kg198 lb | 72 | 90 | 108 | 144 | 36 |
Is 60 grams of protein too much for a woman? No: at 60 kg that is exactly 1.0 gram per kilogram, at 70 kg 0.86. Is 100 grams a lot? At 70 kg it is 1.43 grams per kilogram, within the US range; at 60 kg, 1.67, just over it.
Why protein needs rise with age
Older muscle needs a bigger dose to respond fully, a pattern called anabolic resistance. In pooled lab data, muscle building after one meal leveled off at about 0.40 grams per kilogram in men around 71, against 0.24 in men around 22, a borderline difference per body weight.
In a trial with 37 men averaging 71, 20 grams of whey raised muscle building at rest; after a leg workout, 40 grams did more. Both measured muscle protein synthesis over hours: a lab marker, not muscle mass.
The 0.8 comes from nitrogen balance studies in 235 healthy adults: a median need of 0.65, with 0.83 grams covering almost everyone. Age made no significant difference, which does not prove equal needs. A newer amino-acid method puts the average need 36 percent higher, 0.88 against 0.64 grams. Muscle researchers propose at least 1.2 grams and ask for longer trials themselves.
Many miss even 0.8: among 11,680 US adults aged 51 and older, up to 46 percent fell below it in the group 71 and older; those below it also had more daily limitations (an association).
What 25 to 35 grams per meal looks like
Per meal, aim for about 0.4 grams per kilogram, from 24 grams at 60 kg to 36 at 90. On a plate, 100 grams of chicken breast brings 31; the chart shows ten more portions. It is an orientation from short lab studies in men, not a limit.
| Portion | Grams of protein |
|---|---|
| 200 g firm tofu | 35 |
| 150 g cooked salmon | 33 |
| 100 g roasted chicken breast | 31 |
| 100 g canned tuna, drained | 29 |
| 250 g low-fat cottage cheese | 26 |
| 250 g cooked lentils | 23 |
| 200 g Greek yogurt | 20 |
| 3 large eggs | 19 |
| 300 ml reduced-fat milk | 10 |
| 30 g Swiss cheese | 8 |
| 2 slices whole-wheat bread | 8 |
Are 2 eggs enough? At about 13 grams, not for a meal; with 2 slices of whole-wheat bread and 30 grams of Swiss cheese, breakfast reaches about 29.
Can your body use more than 30 grams at once? In the lab, yes: after a full-body workout, 100 grams kept muscle building going longer than 25 grams, past 12 hours, in a trial with 36 young men. Older people were not tested. Among 1,081 US adults aged 50 to 85, those eating more meals of 30 to 45 grams also had more leg muscle, again an association.
Should you spread protein over the day?
Spreading protein is mainly an easy way to reach the daily total. Breakfast is the gap, at 10 to 12 grams. In trials of people over 50, spread, timing and breakfast protein showed no measurable muscle effect. The example day below reaches about 104 grams at 70 kg, 1.5 per kilogram.
| Meal | Older people in the Netherlands (food records) | Example day, 70 kg |
|---|---|---|
| Breakfast | 10 to 12 | 29 |
| Lunch | 15 to 23 | 42 |
| Dinner | 24 to 31 | 33 |
Does an even spread build more? In 8 adults with a mean age of 37, three even meals raised 24-hour muscle building 25 percent over a dinner-heavy day. In a trial with 20 adults aged 52 to 75, 1.5 grams instead of 0.8 improved protein balance; the spread did not, measurably.
In a meta-analysis, the 3,204 people living at home, mean age about 75, got only a very small muscle gain from extra protein. In seven small trials of 305 people aged 60 and over, breakfast protein did not clearly add muscle or strength, on very uncertain evidence. Over two years, adults aged 67 to 84 who spread protein evenly had more lean mass but did not lose measurably less. Before bed, 40 grams of milk protein raised overnight muscle building in a trial with 48 men averaging 72, 20 grams not clearly, in one night.
Protein builds muscle with strength training
Protein turns into muscle when you train. A meta-analysis gathered 28 trials of people with a mean age of 50 or more. In those with strength training, extra protein added about half a kilogram of arm and leg muscle and 1.7 kilograms of grip strength against lower-protein controls; the muscle gain was significant only in people with sarcopenia or frailty. Without training, there was no added benefit.
In 49 trials of adults who lifted, gains stopped rising near 1.6 grams per kilogram a day on average, and the benefit shrank with age.
| Tested | In whom | Result | Certainty |
|---|---|---|---|
| More protein with strength training | 28 trials, mean age 50 or more | +0.54 kg arm and leg muscle, +1.71 kg grip strength against lower-protein controls | Low to moderate, high heterogeneity; muscle gain significant only with sarcopenia or frailty |
| More protein without strength training | Same 28 trials | No added benefit | Low to moderate |
| Higher protein intake while lifting | 74 trials, healthy adults; subgroup 65 and older | Small extra lean mass (standardized difference 0.22); from 65, seen at 1.2 to 1.59 g/kg a day | Moderate; low for the 65+ subgroup |
| Where the gain leveled off | 49 trials, 1,863 adults doing strength training | No further lean-mass gain above about 1.62 g/kg a day; smaller benefit with age | Moderate |
| Protein supplements, not frail | 36 trials, 1,682 older adults, most already eating enough | No significant effect on lean mass, strength or walking | Moderate |
| Protein supplements, by health | Overview of 33 meta-analyses | No gain in healthy older people; small gains with long-term conditions such as frailty, more certain with exercise | Medium for long-term conditions |
In healthy adults who lift, the extra lean mass was small. While losing weight after 50, higher-protein diets kept more lean mass and shed more fat in 20 trials; see body recomposition for keeping muscle.
Observational data are mixed: among 2,066 adults aged 70 to 79, the top fifth for protein lost about 40 percent less lean mass in three years than the bottom fifth (adjusted), yet in nine long-term studies of 12,424 people averaging about 85, more protein did not measurably slow the decline in physical function. Start with strength training after 40.
Do you need protein powder?
Only when food falls short: with a small appetite, after an illness or with frailty. For older people without frailty, supplements made no significant difference to muscle, strength or walking, even with training; most already ate enough. An overview of 33 meta-analyses found none in healthy older people but small gains with long-term conditions such as frailty, more certain with exercise. For muscle loss, see sarcopenia tests and treatment.
Plant or animal? In 30 trials plant protein built slightly less muscle overall, but from 60 the difference was small and not significant, nor did strength differ significantly.
Is more protein safe for the kidneys?
For kidneys without disease, trials found no consistent signs of harm. In 22 trials of high-protein diets, often 2 grams per kilogram or more, the estimated filtration rate rose; creatinine did not change significantly, and most trials were short. The filtration rate (GFR) is how much blood the kidneys clean per minute. The exception is a filtration rate below 30 without dialysis, where the kidney doctor sets the amount.
Start with your lowest-protein meal, breakfast in the food records, and bring it up to your per-meal amount from the table; lunch comes next.
