The 4·4·9 shorthand adds to 68 kcal; USDA publishes 73 kcal−5 kcal, 6.8% 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 frog legs, raw compares

Among the 68 finfish and shellfish products items on this site, frog legs, raw ranks 66 of 68 by calorie density, against a category average of 114 kcal per 100 g — so it is about 36% less calorie-dense than typical for its group.

It carries 22.5 g of protein per 100 calories — a genuinely protein-dense food.

To burn off one leg (33 kcal), a 70 kg adult would walk for roughly 7 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 frog legs, raw?

Frog legs, raw contains 73 calories per 100 g, which works out to about 33 calories per leg. It also provides 16.4 g of protein, 0.0 g of carbohydrate and 0.3 g of fat per 100 g.

What is the macro breakdown of frog legs, raw?

By calories, frog legs, raw is roughly 0% carbohydrate, 96% protein and 4% fat. That makes it a predominantly protein-based food.

How long does it take to burn off a leg?

About 7 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 frog legs, 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.
