Daily Protein Intake for Men: How Much Protein Do Men Need? (Chart by Weight)

Short answer: The official minimum daily protein intake for men is 0.8 grams per kilogram of body weight (0.36 g per pound), which works out to about 56 grams a day for a reference adult man. That number prevents deficiency, but it is not the target most active or aging men should aim for. Men in their 40s and 50s usually do better around 1.0 to 1.2 g/kg, and men who lift weights benefit from roughly 1.4 to 1.6 g/kg, spread across 3 or 4 meals of about 20 to 40 grams each.

Key Takeaways

• The RDA for adult men is 0.8 g of protein per kg of body weight per day (about 56 g for a reference man). It is a floor, not an optimal goal.^[1][6]
• Dietitians at Mayo Clinic Health System suggest 1.0 to 1.2 g/kg for adults from about age 40 to 50 onward, and 1.1 to 1.7 g/kg for people who exercise or lift regularly.^[5]
• A large meta-analysis of 49 trials found that extra protein stopped adding lean mass gains beyond about 1.6 g/kg per day in people doing resistance training.^[2]
• How you spread protein matters: about 20 to 40 g per meal, every 3 to 4 hours, is the pattern sports nutrition experts recommend.^[3]
• More than about 2 g/kg per day offers no extra benefit for most men, and anyone with kidney disease should get a personal target from a doctor.^[4][5]

Daily Protein Intake for Men: The Chart by Body Weight

Protein needs scale with body weight, so the easiest way to find your number is to convert your weight to kilograms (pounds divided by 2.2) and multiply by the factor that matches your age and activity. The table below does the math for you.

One important adjustment: if you carry a lot of extra body fat, multiplying your full scale weight overestimates your needs. Mayo Clinic Health System dietitians recommend using an adjusted body weight in that case, and a registered dietitian can calculate it for you.^[5]

Where the 0.8 g/kg number comes from

The Recommended Dietary Allowance (RDA) of 0.8 g/kg is the amount that meets the basic needs of nearly all healthy adults. University of Florida nutrition specialists translate it to 56 grams a day for men aged 19 to over 70.^[6] Harvard Health Publishing points out that for an active adult, the RDA can supply as little as 10% of daily calories, while the accepted range for protein runs from 10% to 35% of calories.^[1][5] In other words, the RDA sits at the very bottom of a wide, safe range.

How Much Protein Should a Man Eat a Day by Age and Goal?

Sedentary men under 40

If you are healthy, under 40 and not training, the RDA of 0.8 g/kg covers your basic needs. Many men already exceed it without trying. Mayo Clinic Health System notes that men aged 19 to 59 tend to eat more protein than recommended, especially from meat, poultry and eggs.^[5]

Men in their 40s, 50s and beyond

Muscle tends to respond less to protein as men age, and gradual age-related muscle loss (sarcopenia) is a real concern after midlife. That is why Mayo Clinic Health System suggests 1.0 to 1.2 g/kg from about age 40 to 50 onward, which is 75 to 90 grams a day for a 165 lb person.^[5] The PROT-AGE Study Group, an international panel of geriatric and nutrition experts, recommends at least 1.0 to 1.2 g/kg for healthy adults over 65, at least 1.2 g/kg for those who exercise, and 1.2 to 1.5 g/kg for older people with acute or chronic illness.^[4]

Protein is only half the equation. Strength training is the signal that tells your body to use that protein for muscle. If you want a simple way to track whether your strength is holding up, see our grip strength home test.

Men who lift weights or train hard

The International Society of Sports Nutrition (ISSN) recommends 1.4 to 2.0 g/kg per day for most people who exercise and want to build or keep muscle.^[3] The most cited human data on where benefits level off comes from a 2018 systematic review and meta-analysis in the British Journal of Sports Medicine: across 49 randomized trials and 1,863 participants doing resistance training, protein supplementation added lean mass and strength, but total intakes beyond about 1.62 g/kg per day produced no further gains in fat-free mass.^[2] The same analysis found the extra benefit of protein supplementation shrank with increasing age, so older lifters should not rely on protein alone.

Men cutting calories to lose fat

When you eat less, your body is more likely to break down muscle for fuel. For resistance-trained people in a calorie deficit, the ISSN position stand says intakes of 2.3 to 3.1 g/kg may be needed to hold on to lean mass.^[3] That range targets trained athletes dieting hard; for most men, 1.2 to 1.6 g/kg while lifting is a realistic target.

How to Spread Protein Through the Day

Many men eat most of their protein at dinner. The ISSN recommends a more even pattern:

• Per meal: about 0.25 g/kg of high-quality protein, or 20 to 40 g in absolute terms.^[3]
• Spacing: evenly distributed doses every 3 to 4 hours across the day.^[3]
• Around training: protein before or after a workout both help, so timing is mostly a matter of what you tolerate.^[3]
• Before bed: 30 to 40 g of casein (the slow protein in milk and cottage cheese) increased overnight muscle protein synthesis in the studies the ISSN reviewed.^[3]

Mayo Clinic Health System dietitians give a slightly more conservative per meal target of 15 to 30 g and note that more than 40 g in one sitting is no more beneficial.^[5] A good middle ground for most men: 25 to 35 g at each of three meals, plus a protein snack if your daily target is above 100 g.

Best Protein Foods for Men and How Much Protein They Contain

Whole foods can easily cover your needs. The figures below come from University of Florida IFAS Extension.^[6]

Harvard Health Publishing stresses looking at the whole “protein package”: the fats, carbohydrates, vitamins and minerals that come with the protein. Their experts advise against significantly increasing red meat, and especially processed meat, to get more protein.^[1]

If you eat mostly or entirely plants, you can still hit these targets with a variety of legumes, soy foods, grains, nuts and seeds. Our plant-based protein plan for active men walks through a full day of meals.

A sample 120 gram day

Here is how a 200 lb man who lifts weights a few times a week could reach about 120 g, roughly 1.3 g/kg:

• Breakfast: an egg and bean burrito with a glass of milk, about 28 g.^[5]
• Lunch: 3 oz grilled chicken, 1/2 cup black beans and 1/2 cup quinoa, about 37 g.^[6]
• Snack: Greek yogurt, a banana and a hard-boiled egg, about 19 g.^[5]
• Dinner: 6 oz salmon with 1/2 cup brown rice and vegetables, about 36 g.^[6]

Do Men Need Protein Powder?

No, but it can help. The ISSN says whole foods can meet protein needs, while supplements are a practical way to get enough high-quality protein without too many extra calories, especially for men with high training volume or busy schedules.^[3] If you choose a powder, Mayo Clinic Health System dietitians suggest one with about 200 calories or fewer per serving, 5 g of sugar or less, 2 g of saturated fat or less, and no trans fats.^[5] Look for a product verified by an independent lab; our guide to third-party tested supplements explains what the seals mean. Men who train hard may also want to read about creatine for men in their 40s and 50s, which works alongside adequate protein.

Can Men Eat Too Much Protein? Safety and Who Should Be Careful

For healthy men, intakes well above the RDA are generally well tolerated, but more is not always better. Mayo Clinic Health System describes more than 2 g/kg per day as excessive (about 150 g a day for a 165 lb person), because the extra protein is simply burned for energy or stored as fat.^[5] The same article flags two practical concerns:

• Heart health: many high-protein foods are also high in total and saturated fat, which can raise blood lipids.^[5]
• Kidneys: extra protein can add work for the kidneys, which matters for people predisposed to kidney disease.^[5]

The PROT-AGE recommendations explicitly exclude people with severe kidney disease (eGFR below 30) who are not on dialysis, because they may need to limit protein.^[4]

Talk to your doctor or a registered dietitian before raising your protein if you: have chronic kidney disease or reduced kidney function, have diabetes with kidney involvement, have gout or a history of kidney stones, are taking a weight-loss medication, are significantly underweight, or have been told to follow a special diet for liver or heart disease.

Frequently Asked Questions

How much protein does a 200 lb man need a day?

A 200 lb (91 kg) man needs at least 73 grams a day to meet the RDA. If he is over 40 or moderately active, about 91 to 109 grams is a better target, and if he lifts weights regularly, about 127 to 145 grams.

Is 150 grams of protein a day too much for a man?

It depends on body weight. For a 225 lb man who lifts, 150 grams falls within the 1.4 to 1.6 g/kg range. For a 165 lb man, it is about 2 g/kg, which Mayo Clinic Health System dietitians consider more than needed. Men with kidney problems should get a personal limit from their doctor.

Do men need more protein as they get older?

Yes, in most cases. Expert groups suggest 1.0 to 1.2 g/kg per day for healthy older adults, higher than the 0.8 g/kg RDA, because aging muscle responds less to protein. Pairing that intake with strength training gives the best results.

How much protein can your body absorb in one meal?

Your body absorbs almost all the protein you eat, but the muscle building response appears to level off at roughly 20 to 40 grams per meal for most people. Spreading protein across 3 or 4 meals is a more effective way to use it than eating one very large serving.
