The 4·4·9 shorthand adds to 67 kcal; USDA publishes 60 kcal — +7 kcal, 11.7% 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
- 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 fruit without refuse | 3.2 g | 2 | 0.0 g | 0.5 g | 0.0 g |

A dash means the nutrient was not measured for this item, which is not the same as zero.

How longans, raw compares
Among the 92 fruits and fruit juices items on this site, longans, raw ranks 42 of 92 by calorie density, against a category average of 74 kcal per 100 g — so it is about 19% less calorie-dense than typical for its group.
It carries 2.2 g of protein per 100 calories, so it is not a meaningful protein source.
To burn off one fruit without refuse (2 kcal), a 70 kg adult would walk for roughly 0 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 longans, raw?
Longans, raw contains 60 calories per 100 g, which works out to about 2 calories per fruit without refuse. It also provides 1.3 g of protein, 15.1 g of carbohydrate and 0.1 g of fat per 100 g.
What is the macro breakdown of longans, raw?
By calories, longans, raw is roughly 91% carbohydrate, 8% protein and 1% fat. That makes it a predominantly carbohydrate-based food.
How long does it take to burn off a fruit without refuse?
About 0 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 longans, 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.
