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 pizza (cheese, regular crust) the split is:
- Protein: 11.4 g × 4 = 46 kcal — 17% of calories
- Carbohydrates: 33.3 g × 4 = 133 kcal — 50% of calories
- Fat: 9.7 g × 9 = 87 kcal — 33% of calories
- Most of the energy in pizza (cheese, regular crust) comes from carbohydrate (50% of calories).
- For 200 kcal you can eat about 75 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 |
|---|---|---|---|---|
| Pizza (cheese, regular crust)this page | 266 | 11.4 g | 33.3 g | 9.7 g |
| Pepperoni pizza (pepperoni, regular crust) | 282 | 11.7 g | 32 g | 11.9 g |
| Thin crust pizza (cheese, thin crust) | 302 | 12.9 g | 31.2 g | 14 g |
What actually changes the number
A slice of 14-inch cheese pizza from a chain is about 285 kcal, and a whole pizza around 2,300. Slices vary from 90 to 150 g, so the count of slices is a rough measure — photograph the pizza before the first one goes.
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 pizza 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.
