How Much Protein Do You Need a Day? What the New Guidelines Say

The 2025–2030 Dietary Guidelines for Americans, released in January 2026, set a protein goal of 1.2 to 1.6 grams per kilogram of body weight a day (about 0.5 to 0.7 grams per pound). That's well above the long-standing Recommended Dietary Allowance (RDA) of 0.8 grams per kilogram. Both numbers are real, and experts don't fully agree on which one fits most people. Here's what each means, how to find your own range, and what to eat to reach it.

The Short Answer

To find your range, divide your weight in pounds by 2.2 to get kilograms, then multiply.

Body weight	RDA (0.8 g/kg)	Dietary Guidelines range (1.2 to 1.6 g/kg)
130 lb (59 kg)	about 47 g	about 71 to 95 g
150 lb (68 kg)	about 55 g	about 82 to 109 g
180 lb (82 kg)	about 65 g	about 98 to 131 g

The RDA is the amount that meets the needs of nearly all healthy adults. The guidelines range is higher and is adjusted for individual calorie needs. Where you land depends on your age, activity level, and health.

Why Do the Two Numbers Differ?

The 0.8 g/kg RDA comes from nitrogen-balance studies, a method that estimates the minimum needed to avoid losing protein. The new guidelines reflect a shift toward the idea that higher intakes may support muscle and overall health, and they tell Americans to prioritize protein at every meal. They list a variety of animal sources (eggs, poultry, seafood, red meat) and plant sources (beans, peas, lentils, nuts, seeds, soy).

Not everyone is convinced. Brown University Health noted that the increase wasn't part of the advisory committee's report and said some of the protein and fat recommendations aren't supported by current science. Other clinicians point to evolving evidence that needs may be higher than the old benchmark.

The honest takeaway: 0.8 is the baseline most healthy adults are expected to meet, the guidelines' range is a higher goal, and the case for going higher is clearest for older adults and people who are physically active.

Who May Benefit From More

• Older adults: Muscle mass tends to decline with age, and dietitians have long recommended more protein for older adults. The new guidelines also note that some older adults need fewer calories but still need as much or more protein.
• People who are physically active: If you're lifting weights, see our guide to strength training for how to start, and talk to a dietitian about how much protein fits your routine.
• People managing their weight: Eating protein at meals can help you feel full longer, but you don't need an extreme high-protein diet. For the bigger picture, see our evidence-informed weight management tips.

Do Most Americans Need to Eat More Protein?

Not necessarily. Clinicians note that Americans aren't broadly protein deficient. Intake of poultry, beef, and eggs is generally adequate or even high, while people tend to fall short on seafood, shellfish, nuts, seeds, and plant-based proteins. For many people, the bigger win isn't more protein but better sources.

Protein Food Chart

Food	Serving	Protein (g)
Chicken breast, cooked	3 oz	about 25
Canned tuna	3 oz	about 20
Salmon, cooked	3 oz	about 20
Cottage cheese	½ cup	about 14
Greek yogurt, plain nonfat	½ cup	about 11
Tofu, firm	½ cup	about 10
Lentils, cooked	½ cup	about 9
Black beans	½ cup	about 8
Peanut butter	2 tablespoons	about 8
Milk	1 cup	about 8
Egg	1 large	about 6
Almonds	1 oz	about 6
Whole-wheat bread	1 slice	about 3

Values vary slightly by source and preparation. A handy rule from Johns Hopkins Medicine: 1 ounce of cooked meat, poultry, or fish provides about 7 grams of protein, so a 3-ounce portion (about the size of a deck of cards) provides about 21 grams.

What a 90-Gram Day Looks Like

• Breakfast: ½ cup plain nonfat Greek yogurt (about 11 g) plus 1 oz almonds (about 6 g), roughly 17 g
• Lunch: 3 oz canned tuna (about 20 g) on 2 slices of whole-wheat bread (about 6 g), roughly 26 g
• Snack: ½ cup cottage cheese, about 14 g
• Dinner: 3 oz chicken breast (about 25 g) plus ½ cup black beans (about 8 g), roughly 33 g

That adds up to about 90 grams, which is the low end of the guidelines' range for a 165-pound person and well above the RDA of about 60 grams for that weight.

Eating mostly plants? Swap the chicken and tuna for tofu, lentils, beans, and peanut butter from the chart. Beans and lentils also bring fiber, so see our guide to how much fiber you need a day. If you skip animal foods entirely, keep an eye out for signs of vitamin B12 deficiency.

Whole Foods First

Clinicians recommend prioritizing whole-food protein over supplements or ultra-processed protein products. The guidelines also keep the cap on saturated fat at under 10% of daily calories (about 20 grams on a 2,000-calorie diet) and sodium at under 2,300 milligrams a day, so choosing lean poultry, fish, beans, and nuts matters, not just hitting a number.

Who Should Talk to a Doctor First

• Kidney disease: The American Kidney Fund says protein needs depend on your body size, kidney function, and stage of disease. Follow your care team's advice rather than the general range.
• Other medical conditions, pregnancy, or breastfeeding: Needs differ by life stage and health, so ask your healthcare provider.

The Bottom Line

The RDA of 0.8 g/kg is the baseline for most healthy adults. The 2025–2030 guidelines point higher, to 1.2 to 1.6 g/kg, with the clearest case for older adults and active people. Most Americans aren't short on protein overall, so focus on the quality of your sources, spread protein across your meals, and check with your doctor if you have kidney disease or another condition.

Frequently Asked Questions

How much protein do I need per day?
The RDA is 0.8 grams per kilogram of body weight, and the 2025–2030 Dietary Guidelines set a goal of 1.2 to 1.6 grams per kilogram. For a 150-pound person, that's about 55 grams versus about 82 to 109 grams.

Is 0.8 g/kg enough?
The RDA is meant to meet the needs of nearly all healthy adults. Some experts argue higher intakes are better, especially for older and active people, but this is still debated.

Does the 1.2 to 1.6 g/kg range apply to everyone?
It's the federal goal for adults, adjusted for calorie needs. Experts debate who benefits most, so check with your provider, especially if you have a medical condition.

Do I need protein powder?
Whole foods come first. Supplements and ultra-processed protein products shouldn't be the foundation of your protein intake.

What are the best plant-based protein sources?
Beans, peas, lentils, nuts, seeds, and soy foods like tofu and edamame.

Can protein help with weight loss?
It can help you feel full longer, and strength training helps you keep muscle while losing weight. Neither is a magic fix.
