The 4·4·9 shorthand adds to 110 kcal; USDA publishes 116 kcal−6 kcal, 5.2% apart. That gap is expected, not an error: USDA derives energy with food-specific factors and, for many items, discounts the fibre that the shorthand still counts at four. The published figure is the better one, so the axis above is scaled to it and the shares are what the shorthand is genuinely good at.

How this is worked out

  1. USDA measures every nutrient per 100 g of edible portion. That row is published here unchanged — nothing is rounded up, smoothed or "adjusted".
  2. The energy figure is USDA's own, derived with food-specific factors. This site never computes the calorie count it publishes.
  3. 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.
  4. A serving is a straight proportional conversion of the per-100 g row, using USDA's own household measures for the grams.
  5. 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)

How ostrich, round, raw compares

Among the 95 poultry products items on this site, ostrich, round, raw ranks 78 of 95 by calorie density, against a category average of 179 kcal per 100 g — so it is about 35% less calorie-dense than typical for its group.

It carries 19 g of protein per 100 calories — a genuinely protein-dense food.

To burn off one serving (cooked from 4 oz raw) (99 kcal), a 70 kg adult would walk for roughly 20 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 ostrich, round, raw?

Ostrich, round, raw contains 116 calories per 100 g, which works out to about 99 calories per serving (cooked from 4 oz raw). It also provides 22.0 g of protein, 0.0 g of carbohydrate and 2.4 g of fat per 100 g.

What is the macro breakdown of ostrich, round, raw?

By calories, ostrich, round, raw is roughly 0% carbohydrate, 80% protein and 20% fat. That makes it a predominantly protein-based food.

How long does it take to burn off a serving (cooked from 4 oz raw)?

About 20 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 ostrich, round, raw 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.
