Protein calculator: grams per day for your body weight
Put your weight in and the calculator below returns three separate numbers rather than one, because the sources do not agree and averaging them would produce a figure nobody published. It shows the RDA floor, the range the two expert groups recommend for your situation, and what the 2026 review argues for. Enter pounds or kilograms; it works either way, and it will refuse to give a number for severe kidney disease, which is the one case where the advice reverses. Our product pick for this topic, Advanced Muscle Plus, is in the box near the end of this page.
General information, not medical advice. Figures read from the sources on 9 September 2026. Anyone with kidney disease, or on a protein-restricted diet for any reason, should get an individual target from their own clinician rather than from a calculator.
For decades, the standard nutrition advice on protein has been reassuringly simple: hit the government’s recommended dietary allowance and you are fine. But a growing body of research says that number — set at 0.8 grams per kilogram of body weight — was never meant to be a target for thriving. It was calculated to be the minimum that prevents most healthy adults from losing muscle-building nitrogen. That distinction has become the center of a serious scientific conversation about how much protein people actually need, especially as they get older.
A June 2026 review by Dr. Chris Macdonald of the University of Cambridge, published in Frontiers in Nutrition and covered by ScienceDaily, sharpened the argument. Macdonald contends that current guidelines are built around avoiding deficiency rather than optimizing health, and that “physically active people, older adults, and pregnant women may benefit from significantly higher protein intake.” His proposal is not to scrap the minimums but to supplement them with guidance aimed at the outcomes that matter most in later life: strength, mobility, and independence. That framing echoes what geriatric nutrition experts have been saying for more than a decade.
How much protein do you actually need?
The RDA of 0.8 g/kg comes from the U.S. Dietary Reference Intakes and applies to healthy adults over 19. As the NIH reference tables make clear, it was derived to estimate the smallest amount of protein needed to avoid a net loss of body nitrogen — a deficiency-prevention threshold, not an optimum. Roughly half the population needs less than the RDA to avoid deficiency; the RDA is deliberately set higher so it covers almost everyone. That is a very different question from “how much protein keeps my muscles and strength intact into my 70s and 80s?”
To make the numbers concrete, here is what different intakes look like in grams per day at several body weights. The RDA column is the minimum. The 1.2 g/kg column is the expert-group ceiling for healthy older adults and their floor for anyone exercising or ill; the 1.6 g/kg column is above what either guideline recommends and sits closer to what the 2026 review proposes, shown here so you can see the spread the two bodies of evidence produce.
| Body weight | RDA (0.8 g/kg) | 1.2 g/kg | 1.6 g/kg |
|---|---|---|---|
| 55 kg (121 lb) | 44 g/day | 66 g/day | 88 g/day |
| 65 kg (143 lb) | 52 g/day | 78 g/day | 104 g/day |
| 75 kg (165 lb) | 60 g/day | 90 g/day | 120 g/day |
| 85 kg (187 lb) | 68 g/day | 102 g/day | 136 g/day |
| 95 kg (209 lb) | 76 g/day | 114 g/day | 152 g/day |
The gap between the RDA and the optimal range is not trivial. For a 75 kg adult it is the difference between 60 and 90–120 grams a day — often the difference between a few token bites of protein and a genuinely protein-anchored plate at each meal. (If you carry a lot of excess weight, most clinicians base the calculation on a healthy or adjusted body weight rather than total scale weight, so treat these figures as a starting point.)
Why older adults need more
The case for higher protein in later life rests on real physiology, not marketing. Two overlapping problems are at work.
The first is anabolic resistance. As we age, muscle becomes less responsive to the protein we eat. A given dose of protein triggers a smaller muscle-building signal in a 70-year-old than in a 30-year-old, so older adults need a bigger stimulus — more protein per meal — to get the same effect. The second is sarcopenia, the gradual, age-related loss of muscle mass and strength that quietly erodes balance, walking speed, and the ability to recover from illness or a fall. Left unaddressed, this loss of muscle and function is closely tied to frailty and loss of independence, a link explored in our guide to sudden loss of leg strength and muscle loss in older adults.
These realities are precisely why the leading geriatric nutrition bodies moved past the RDA years ago. The PROT-AGE study group, convened by the European Union Geriatric Medicine Society, recommended in its 2013 position paper (Bauer et al., JAMDA) that healthy older adults aim for at least 1.0 to 1.2 g/kg per day, rising to 1.2 to 1.5 g/kg for those who are exercising or dealing with acute or chronic illness. The ESPEN Expert Group reached a similar conclusion in its 2014 recommendations (Deutz et al., Clinical Nutrition), endorsing roughly 1.0 to 1.5 g/kg per day for people over 65. In other words, the intake many older adults treat as generous — the RDA — is the exact figure both expert panels consider a bare minimum. Protecting the muscle you have is a central theme of our companion piece on building muscle after 60.
Protein distribution and the per-meal threshold
Total daily protein is only half the story. When you eat it matters, because of a concept called the per-meal or leucine threshold.
Muscle protein synthesis — the process of building and repairing muscle — is switched on most effectively when a meal delivers enough of the amino acid leucine at once. Research points to a threshold of roughly 2.5 to 3 grams of leucine per meal, which corresponds to about 25 to 30 grams of high-quality protein. Because of anabolic resistance, older adults may sit at the upper end of that range or need a touch more to get the same response younger adults achieve with less.
The practical takeaway: a typical Western eating pattern that skimps at breakfast (toast and coffee), goes light at lunch, and dumps most of the day’s protein into dinner leaves two of three muscle-building opportunities on the table. Spreading protein evenly — aiming for roughly 25 to 30 grams at each of three meals — hits the threshold multiple times a day and is generally more effective for preserving muscle than the same total eaten mostly at night.
Best protein sources (with amounts)
A food-first approach comfortably covers most people’s needs. Here is roughly how much protein common foods deliver, so you can see how quickly a 25–30 gram meal target comes together.
| Food | Typical serving | Protein (approx.) |
|---|---|---|
| Chicken breast, cooked | 100 g (3.5 oz) | 31 g |
| Salmon, cooked | 100 g (3.5 oz) | 25 g |
| Lean beef, cooked | 100 g (3.5 oz) | 26 g |
| Greek yogurt, plain | 170 g (6 oz) | 17 g |
| Eggs | 2 large | 12 g |
| Cottage cheese | 1/2 cup | 14 g |
| Lentils, cooked | 1 cup | 18 g |
| Tofu, firm | 100 g | 10–12 g |
| Canned tuna | 1 can (drained) | 20–25 g |
| Milk | 1 cup | 8 g |
Animal sources tend to be more concentrated and leucine-rich, but the Frontiers in Nutrition review stresses that well-planned plant-based diets can also meet protein needs — it simply takes more attention to total quantity and to combining sources like legumes, soy, and grains. Older adults leaning plant-forward may need slightly larger portions to clear the per-meal threshold.
Protein and resistance exercise work together
Protein is the raw material; resistance exercise is the signal that tells your body to use it for muscle. Neither works nearly as well alone. Both PROT-AGE and ESPEN pair their protein targets with a clear recommendation for regular strength or resistance training, and both bump the suggested protein intake upward specifically for people who exercise. Lifting, resistance bands, bodyweight work, or any activity that meaningfully loads the muscles helps overcome anabolic resistance, so the protein you eat translates into strength you can actually use — getting out of a chair, climbing stairs, carrying groceries.
For readers weighing whether supplements add anything on top of food and training, we cover the evidence in our reviews of supplements for sarcopenia and the HMB supplement for age-related muscle loss. The short version: real food and resistance exercise do the heavy lifting; supplements are, at most, a modest add-on.

Common myths, honestly addressed
Myth: “High protein damages healthy kidneys.” For people with normal kidney function, current evidence does not show that higher protein intakes within the ranges discussed here harm the kidneys. This claim mostly comes from extrapolating advice meant for people who already have kidney disease. The honest caveat is the flip side: if you do have reduced kidney function, protein does need to be managed with a clinician (see below).
Myth: “Your body can only absorb 30 grams of protein at a time.” Your gut absorbs far more than 30 grams; the ~25–30 gram figure is about maximizing the muscle-building signal per meal, not absorption. Extra protein beyond that per meal is still digested and used — it just does not add much additional muscle-synthesis stimulus at that sitting.
Myth: “More is always better.” This is where the enthusiasm should stop. Pushing intake to very high levels (well above ~1.6 g/kg) has not been shown to deliver meaningfully better muscle or health outcomes for most people, and it can crowd out other nutritious foods. The goal is adequate and well-distributed, not extreme.
Who should be cautious
The higher-protein guidance in this article is aimed at generally healthy older adults. It is not universal.
People with chronic kidney disease are the clearest exception: protein intake often needs to be deliberately limited and closely monitored, and the right amount depends on the stage of disease and other individual factors. If you have reduced kidney function, do not adopt a high-protein pattern without guidance from your doctor or a renal dietitian. Anyone managing liver disease, certain metabolic conditions, or taking medications affected by diet should likewise personalize intake with a professional. Needs are genuinely individual — the ranges here are a well-supported starting point, not a prescription.
Practical daily plan
Here is what an evenly distributed, muscle-friendly day might look like for a healthy older adult aiming for roughly 90–110 grams:
- Breakfast (~25–30 g): Greek yogurt with a scoop of cottage cheese and berries, or two eggs plus a glass of milk.
- Lunch (~25–30 g): A palm-sized portion of chicken, tuna, or tofu over a salad or grain bowl with lentils.
- Dinner (~30 g): A serving of fish or lean meat (about 100–120 g cooked) with vegetables and beans.
- Optional snack: A handful of nuts, a boiled egg, or a small serving of dairy to top up on lighter days.
Combine that with two or three sessions of resistance exercise a week, and you have covered the two levers that matter most for holding onto strength as you age.
Where to buy, if food alone does not reach 25 to 30 g per meal. The guideline numbers above are met with food for most people; a powder is for the one meal that falls short.
- Whey protein isolate, about 25 g of protein per scoop, unflavored so it can go into oatmeal or yogurt. Sports Research® Whey Protein Isolate Powder, Unflavored (2lb Bag) (Amazon)
- Pea and rice protein blend, 20 to 25 g per scoop, if dairy is a problem. NAKED Rice 1Lb – Organic Brown Rice Protein Powder – Vegan Protein Powder,… (Amazon)
- A meal shake, if you want the micronutrients with it — but read the arithmetic before you buy. LyfeFuel’s Essentials Shake is pea and rice protein at 18 g a scoop, which does not reach this page’s 25 to 30 g on its own; two scoops is 36 g and does. It is a meal replacement with 27 vitamins and minerals rather than a plain protein, so two scoops also doubles those — fine once a day (vitamin A lands near 1,500 mcg against an upper limit of 3,000, vitamin D near 60 mcg against 100), not at every meal. And it is the expensive way to buy protein: about $2.92 a serving, so $5.84 for the 36 g, against roughly a dollar for the same protein from either option above. Buy it for the convenience and the micronutrients, not to hit a protein target cheaply. LyfeFuel Essentials Nutrition Shake
One caution from USDA data: a scoop of whey carries about 1 g of fiber, and every animal protein on the list carries none. If your protein plan is built from chicken, yogurt and powder, add a cup of lentils or beans; our table of 33 foods shows which ones carry both.

Frequently Asked Questions
Is there a protein calculator for grams per day?
Yes, on this page. Enter your body weight in pounds or kilograms and it returns the RDA floor (0.8 g/kg), the expert-group range for your situation (1.0 to 1.2 g/kg if you are healthy, 1.2 to 1.5 if you are exercising or unwell), and the higher figure the 2026 review proposes, each with the source it came from. Most protein intake calculators give you one number and do not say where it came from; the numbers here disagree with each other, so we show the disagreement instead of hiding it in an average.
How much protein do I need per day?
The RDA is 0.8 grams per kilogram of body weight — about 44 grams for a 55 kg person or 60 grams for a 75 kg person — but that is a minimum to prevent deficiency, not an optimum. Expert groups put healthy older adults at 1.0–1.2 g/kg per day, and 1.2–1.5 g/kg for those exercising or ill; a 2026 review argues for around 1.5 g/kg.
How much protein do older adults need?
Expert groups recommend more than the RDA for people over 65. PROT-AGE suggests at least 1.0–1.2 g/kg per day (up to 1.2–1.5 g/kg with exercise or illness), and ESPEN recommends roughly 1.0–1.5 g/kg per day. For a 75 kg adult, that is about 90–120 grams a day.
Is 0.8 g/kg enough protein?
It is enough to prevent outright deficiency in most healthy adults, which is what it was designed to do. It is likely not optimal for preserving muscle, strength, and independence with age, which is why geriatric nutrition experts recommend more for older adults.
How much protein per meal is best?
Around 25 to 30 grams of high-quality protein per meal, three times a day, appears to best stimulate muscle building. This corresponds to roughly 2.5–3 grams of leucine per meal. Older adults may need the upper end of that range because muscle becomes less responsive to protein with age.
Can too much protein harm your kidneys?
For people with normal kidney function, protein intakes in the ranges discussed here have not been shown to damage the kidneys. The concern applies mainly to people who already have kidney disease, who should limit and monitor protein under medical guidance.
What are the best sources of protein?
Concentrated, leucine-rich options include chicken, fish, lean meat, eggs, Greek yogurt, cottage cheese, and milk. Plant sources like lentils, tofu, soy, and beans work well too, though they generally require larger or combined portions to match the per-meal threshold.
Do you need protein powder?
No. Most people can hit their targets with whole foods. Protein powder is a convenient way to top up — useful if you struggle to reach 25–30 grams at a meal or have a poor appetite — but it is optional, not essential.
How much protein to build muscle?
Aim at the top of the guideline range and above: PROT-AGE advises 1.2 g/kg per day or more for people who are exercising, and the 2026 review argues for about 1.5 g/kg, so roughly 1.2–1.5 g/kg is the evidence-backed band, distributed as 25–30+ grams per meal and combined with regular resistance training. Protein supplies the building blocks; the exercise is what signals your body to add muscle.
The Bottom Line
The RDA of 0.8 g/kg was designed to keep you from becoming deficient, not to keep you strong. For most healthy older adults, the evidence — from the PROT-AGE and ESPEN expert groups to the 2026 Frontiers in Nutrition review — points above the RDA — the expert groups to 1.0 to 1.2 grams per kilogram per day for healthy older people and 1.2 to 1.5 for those exercising or ill, the 2026 review further still, to about 1.5. Spread it across meals at roughly 25 to 30 grams each and pair it with resistance exercise. This is about maintaining muscle, strength, and independence with age, not a license for extreme protein: intakes well beyond that range are not clearly better for most people, and anyone with kidney disease needs individualized medical guidance. Lead with real food, distribute it through the day, keep lifting, and you have the two things that matter most working in your favor.
