The 4·4·9 shorthand adds to 407 kcal and USDA publishes 407 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 slice | 26.0 g | 106 | 3.3 g | 0.2 g | 10.2 g |
| 1 package | 446.0 g | 1,815 | 55.9 g | 3.7 g | 175.1 g |

How bacon, pre-sliced, reduced/low sodium compares
Among the 83 pork products items on this site, bacon, pre-sliced, reduced/low sodium ranks 18 of 83 by calorie density, against a category average of 290 kcal per 100 g — so it is about 40% more calorie-dense than typical for its group.
It carries 3.1 g of protein per 100 calories, so it is not a meaningful protein source.
To burn off one slice (106 kcal), a 70 kg adult would walk for roughly 22 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.

How long does it take to burn off a slice?
About 22 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 bacon, pre-sliced, reduced/low sodium 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.
