The 4·4·9 shorthand adds to 243 kcal and USDA publishes 245 kcal. The arithmetic closes, so the axis above is simply that figure divided by the shares.

How this is worked out
- USDA measures every nutrient per 100 g of edible portion. That row is published here unchanged — nothing is rounded up, smoothed or "adjusted".
- The energy figure is USDA's own, derived with food-specific factors. This site never computes the calorie count it publishes.
- The Atwater shorthand 4 · 4 · 9 is applied to the protein, carbohydrate and fat grams only to split that energy into shares — and where the shorthand disagrees with the published figure, the gap is printed rather than hidden.
- A serving is a straight proportional conversion of the per-100 g row, using USDA's own household measures for the grams.
- The walking figure uses MET 4.0 at 70 kg, the same equation the sister site publishes.
per serving = per 100 g × serving grams ÷ 100 energy shares = 4·P + 4·C + 9·F (P, C, F in grams) walk minutes = kcal ÷ (4.0 × 3.5 × 70 ÷ 200)
Calories in a typical serving
Per-100 g figures are useful for comparison but nobody eats 100 g of anything on purpose. These are the USDA's own household measures.
| Serving | Grams | Calories | Protein | Carbs | Fat |
|---|---|---|---|---|---|
| 1 oz | 28.4 g | 70 | 3.4 g | 12.4 g | 0.6 g |
| 1 slice | 19.0 g | 47 | 2.3 g | 8.3 g | 0.4 g |

How bread, protein compares
Among the 129 baked products items on this site, bread, protein ranks 112 of 129 by calorie density, against a category average of 337 kcal per 100 g — so it is about 27% less calorie-dense than typical for its group.
It carries 4.9 g of protein per 100 calories, so it is not a meaningful protein source.
To burn off one oz (70 kcal), a 70 kg adult would walk for roughly 14 minutes — see the walking calculation on our sister site, or pick a different activity. Treat that as a sense of scale rather than a rule: eating and moving are not a simple ledger.

Questions this entry settles
How many calories are in bread, protein?
Bread, protein contains 245 calories per 100 g, which works out to about 70 calories per oz. It also provides 12.1 g of protein, 43.8 g of carbohydrate and 2.2 g of fat per 100 g.
What is the macro breakdown of bread, protein?
By calories, bread, protein is roughly 72% carbohydrate, 20% protein and 8% fat. That makes it a predominantly carbohydrate-based food.
How long does it take to burn off a oz?
About 14 minutes of ordinary walking for a 70 kg adult (MET 4.0). That is a rough guide for scale, not a prescription — appetite and activity interact in ways a simple subtraction does not capture.
Is this figure exact for the bread, protein I bought?
No. These are USDA reference values, averaged across samples. Real foods vary with variety, ripeness, growing conditions, cut, brand and how they were cooked — 10–20% either way is normal. Use them for planning, not precision.
