The 4·4·9 shorthand adds to 896 kcal and USDA publishes 897 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

How animal fat, bacon grease compares
Among the 55 fats and oils items on this site, animal fat, bacon grease ranks 13 of 55 by calorie density, against a category average of 762 kcal per 100 g — so it is about 18% more calorie-dense than typical for its group.
It carries 0 g of protein per 100 calories, so it is not a meaningful protein source.
To burn off one tsp (39 kcal), a 70 kg adult would walk for roughly 8 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.

Is this figure exact for the animal fat, bacon grease 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.
