How many calories are in chocolate?
A standard 45 g bar of milk chocolate is about 240 kcal. Two squares of dark chocolate (10 g) are about 60 kcal, and 100 g of almost any chocolate falls between 520 and 610 kcal. The spread between types is narrower than people expect, and it runs opposite to the usual assumption.
Per portion
| Portion | Calories | Protein | Carbs | Fat |
|---|---|---|---|---|
| One square, milk (5 g) | ~27 kcal | 0.4 g | 3 g | 1.5 g |
| One square, 70% dark (5 g) | ~30 kcal | 0.4 g | 2.3 g | 2.2 g |
| Two squares, 70% dark (10 g) | ~60 kcal | 0.8 g | 4.6 g | 4.3 g |
| Standard bar, milk (45 g) | ~240 kcal | 3.4 g | 26 g | 13.5 g |
| Caramel or wafer bar (50 g) | ~230–250 kcal | 2.5 g | 31 g | 11 g |
| 100 g milk chocolate | ~535 kcal | 7.5 g | 59 g | 30 g |
| 100 g dark, 70–85% | ~600 kcal | 8 g | 46 g | 43 g |
| 100 g white chocolate | ~540 kcal | 6 g | 59 g | 31 g |
What changes the number
Fillings dilute it. Solid chocolate is 30–43% fat. A caramel, nougat or wafer bar is partly sugar and flour, both lighter per gram than cocoa butter, so filled bars run about 450–510 kcal per 100 g. Lower per gram, but sold in bigger pieces, so the total is the same or higher.
Nuts hold it level, fruit lowers it. Nuts are roughly as dense as chocolate, so a hazelnut bar is still near 560 kcal per 100 g. Fruit and raisin pieces bring it to about 480.
Cocoa powder is not chocolate. Most of the fat is pressed out, leaving about 230 kcal per 100 g — a heaped teaspoon is 12 kcal. What makes a shop hot chocolate 300–400 kcal is the milk, sugar and cream.
“No added sugar” saves less than it looks. Swapping sugar for maltitol or erythritol trims roughly 10–15% per 100 g, because the fat — the larger half of the calories — is untouched. Most land near 470–500 kcal per 100 g. The per-100 g column settles it in a second.
Why dark chocolate is not the lower-calorie option
Raising the cocoa percentage takes out sugar and puts in cocoa butter. Sugar is 4 kcal per gram; fat is 9. Milk chocolate is about 535 kcal per 100 g, 50–60% dark about 545, and 70–85% dark about 600. Darker chocolate is usually slightly higher per gram, and gram for gram white chocolate is no worse than milk.
The satiety half of the argument does hold, though. Dark chocolate is bitter and intense, two squares is a normal stopping point, and a bar can last a week rather than an evening. That is a real effect — it just works through portion size, not through the figure on the wrapper.
Where it fits in a deficit
At 5–6 kcal per gram with no water, chocolate sits at the top of the calorie-density ladder: a 100 g bar holds the energy of a full meal in something you can finish standing up. Its 7–8 g of protein per 100 g is irrelevant at the portions anyone eats.
None of which makes it a food to remove. A planned 20–25 g of dark after dinner is 120–150 kcal and holds up better than the same calories spent on a biscuit mid-morning. The failure mode is the unplanned bar, which arrives in 45 g and 240 kcal units and is easy to repeat twice in a day without counting either. Single bars beat sharing blocks, and chocolate is easier to build into a calorie deficit than to build one around it. A scoop of ice cream comes in lower than a bar.
