How Much Protein Do I Need at 280 lbs? (280g a Day)
At 280 lbs (127 kg), aim for about 280g of protein a day, or 336g if you prioritize protein. Per-meal split and a sample day from USDA data.
At 280 lbs, a good daily protein target is 280g, using the 1 gram per pound anchor the Nouri app sets by default. If you turn on Prioritize Protein, it rises to 336g. That is 1120 to 1344 calories from protein a day.

How 280g compares to official guidance
280 lbs is about 127 kg. Here is what the main published reference points work out to at that weight:
| Reference | Per kg | At 280 lbs |
|---|---|---|
| RDA (minimum for most adults) | 0.8 g | 102g |
| Dietary Guidelines 2025 to 2030 | 1.2 to 1.6 g | 152 to 203g |
| ISSN, most exercising people | 1.4 to 2.0 g | 178 to 254g |
| ISSN, resistance-trained in a calorie deficit | 2.3 to 3.1 g | 292 to 394g |
| Nouri default (1.0 g/lb) | 2.2 g | 280g |
| Nouri, Prioritize Protein (1.2 g/lb) | about 2.6 g | 336g |
The RDA is a floor to avoid deficiency, not a target for building or keeping muscle. Nouri's default sits just above the ISSN range for most exercising people, and the prioritized setting lands inside the range the ISSN describes for lifters eating in a deficit. If you have kidney disease or another medical condition, set your number with your doctor.
Protein per meal at 280 lbs
| Meals a day | Standard (280g) | Prioritized (336g) |
|---|---|---|
| 3 | 93g | 112g |
| 4 | 70g | 84g |
| 5 | 56g | 67g |
The ISSN describes 0.25 g/kg per dose, about 32g at your weight, or 20 to 40g, spread every 3 to 4 hours. Splitting evenly makes a big daily number feel ordinary.

FAQ
How much protein should a 280 lb person eat a day?
Nouri's anchor is 1 gram per pound, so 280g a day, or 336g with protein prioritized. For comparison, the RDA minimum works out to about 102g and the ISSN range for most exercising people to 178 to 254g at 127 kg.
Is 280 grams of protein a day too much?
For a healthy, active person it is within the range sports nutrition research discusses: 280g is about 2.2 g/kg, between the ISSN's 1.4 to 2.0 g/kg for most exercising people and the 2.3 to 3.1 g/kg it describes for resistance-trained people in a calorie deficit. If you have kidney disease or another medical condition, ask your doctor first.
How much protein per meal at 280 lbs?
280g split evenly is about 93g across three meals, 70g across four, or 56g across five. The ISSN describes 0.25 g/kg (about 32g for you) or 20 to 40g per dose as a general guide.
What does 280g of protein look like in food?
The sample day above reaches 282g from USDA-measured foods: Greek yogurt and eggs at breakfast, chicken breast at lunch, a protein snack, and salmon at dinner, for 1660 calories before sides, oils, and carbs.
Does the target change for men and women?
Not in this math. Nouri's anchor and the published ranges above are all per unit of body weight, so a 280 lb man and a 280 lb woman get the same number. Your total calories are what differ, which the daily calorie needs calculator works out.
