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 nachos (with cheese) the split is:
- Protein: 4.3 g × 4 = 17 kcal — 5% of calories
- Carbohydrates: 34.9 g × 4 = 140 kcal — 40% of calories
- Fat: 21.5 g × 9 = 194 kcal — 55% of calories
- Most of the energy in nachos (with cheese) comes from fat (55% of calories).
- It provides 3.2 g of fibre per 100 g, which is a good amount.
- For 200 kcal you can eat about 60 g.
What actually changes the number
Nachos with cheese are 343 kcal per 100 g, and a sharing plate is 400–600 g — 1,400–2,000 kcal for the table. The chips are half the calories and the cheese most of the rest.
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 nachos 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.
