How Much Protein Do I Need at 140 lbs? (140g a Day)
At 140 lbs (64 kg), aim for about 140g of protein a day, or 168g if you prioritize protein. Per-meal split and a sample day from USDA data.
At 140 lbs, a good daily protein target is 140g, using the 1 gram per pound anchor the Nouri app sets by default. If you turn on Prioritize Protein, it rises to 168g. That is 560 to 672 calories from protein a day.

How 140g compares to official guidance
140 lbs is about 64 kg. Here is what the main published reference points work out to at that weight:
| Reference | Per kg | At 140 lbs |
|---|---|---|
| RDA (minimum for most adults) | 0.8 g | 51g |
| Dietary Guidelines 2025 to 2030 | 1.2 to 1.6 g | 76 to 102g |
| ISSN, most exercising people | 1.4 to 2.0 g | 89 to 127g |
| ISSN, resistance-trained in a calorie deficit | 2.3 to 3.1 g | 146 to 197g |
| Nouri default (1.0 g/lb) | 2.2 g | 140g |
| Nouri, Prioritize Protein (1.2 g/lb) | about 2.6 g | 168g |
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 140 lbs
| Meals a day | Standard (140g) | Prioritized (168g) |
|---|---|---|
| 3 | 47g | 56g |
| 4 | 35g | 42g |
| 5 | 28g | 34g |
The ISSN describes 0.25 g/kg per dose, about 16g 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 140 lb person eat a day?
Nouri's anchor is 1 gram per pound, so 140g a day, or 168g with protein prioritized. For comparison, the RDA minimum works out to about 51g and the ISSN range for most exercising people to 89 to 127g at 64 kg.
Is 140 grams of protein a day too much?
For a healthy, active person it is within the range sports nutrition research discusses: 140g 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 140 lbs?
140g split evenly is about 47g across three meals, 35g across four, or 28g across five. The ISSN describes 0.25 g/kg (about 16g for you) or 20 to 40g per dose as a general guide.
What does 140g of protein look like in food?
The sample day above reaches 141g from USDA-measured foods: Greek yogurt and eggs at breakfast, chicken breast at lunch, a protein snack, and salmon at dinner, for 880 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 140 lb man and a 140 lb woman get the same number. Your total calories are what differ, which the daily calorie needs calculator works out.
