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 mozzarella (part-skim) the split is:
- Protein: 24.3 g × 4 = 97 kcal — 39% of calories
- Carbohydrates: 2.8 g × 4 = 11 kcal — 4% of calories
- Fat: 15.9 g × 9 = 143 kcal — 57% of calories
- Most of the energy in mozzarella (part-skim) comes from fat (57% of calories).
- With 24.3 g of protein per 100 g it counts as a high-protein food.
- That is 9.6 g of protein per 100 kcal — a useful number when protein is your target.
- It is high in sodium: 619 mg per 100 g.
- For 200 kcal you can eat about 80 g.
Compare preparations
The same food, prepared differently. Cooking removes water (so calories per 100 g rise), adds fat (so they rise further), or both.
| Preparation | Calories | Protein | Carbohydrates | Fat |
|---|---|---|---|---|
| Mozzarella (whole milk) | 299 | 22.2 g | 2.4 g | 22.1 g |
| Mozzarella (part-skim)this page | 254 | 24.3 g | 2.8 g | 15.9 g |
What actually changes the number
Part-skim mozzarella — the pizza cheese — is 254 kcal per 100 g, about 15% less than whole-milk. It is still the single biggest calorie source on most pizzas after the crust.
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 mozzarella 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.
