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 lasagna (restaurant, with meat) the split is:
- Protein: 10.8 g × 4 = 43 kcal — 23% of calories
- Carbohydrates: 11.4 g × 4 = 45 kcal — 25% of calories
- Fat: 10.7 g × 9 = 96 kcal — 52% of calories
- Most of the energy in lasagna (restaurant, with meat) comes from fat (52% of calories).
- For 200 kcal you can eat about 110 g.
What actually changes the number
Restaurant meat lasagna is 185 kcal per 100 g, and a serving of 300–400 g is 550–740 kcal. Cheese and béchamel are the variables; a photo sees the layers but not their richness.
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 lasagna 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.
