Calories, protein, carbohydrate and fat per 100 g and per serving, from the USDA reference database — plus what actually changes the number on your plate.
Short answer
100 g of brie contains 334 kcal, with 20.8 g of protein, 0.5 g of carbohydrate and 27.7 g of fat.
A typical serving — 1 piece, about 30 g — is roughly 100 kcal.
That is a fairly calorie-dense food, so portion size matters.

Where the calories come from
Calories come from three macronutrients: protein and carbohydrate at 4 kcal per gram, fat at 9 kcal per gram. For brie the split is:
- Protein: 20.8 g × 4 = 83 kcal — 25% of calories
- Carbohydrates: 0.5 g × 4 = 2 kcal — 1% of calories
- Fat: 27.7 g × 9 = 249 kcal — 75% of calories
- Most of the energy in brie comes from fat (75% of calories).
- With 20.8 g of protein per 100 g it counts as a high-protein food.
- That is 6.2 g of protein per 100 kcal — a useful number when protein is your target.
- It is high in sodium: 629 mg per 100 g.
- For 200 kcal you can eat about 60 g.
What actually changes the number
Brie is 334 kcal per 100 g, less than cheddar because of its moisture, but it is rarely eaten in cheddar-sized amounts. A wedge on a cheese board is easily 60 g and 200 kcal.
How accurate are these numbers?
The values on this page are reference averages from the USDA FoodData Central database (SR Legacy release), measured on samples of brie as sold and prepared in the United States. Your portion will differ: produce varies by variety and ripeness, meat by cut and trim, and anything cooked by the fat and water it gained or lost.
For most foods the per-100 g figure is reliable to within about 10%. The larger uncertainty is almost always the weight of what is on your plate and the cooking fat you cannot see — the two things worth checking before you worry about the database.
