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 chocolate chip cookie (shop-bought) the split is:
- Protein: 5.1 g × 4 = 20 kcal — 4% of calories
- Carbohydrates: 65.4 g × 4 = 261 kcal — 52% of calories
- Fat: 24.7 g × 9 = 222 kcal — 44% of calories
- Most of the energy in chocolate chip cookie (shop-bought) comes from carbohydrate (52% of calories).
- 32.9 g of its carbohydrate per 100 g is sugar.
- For 200 kcal you can eat about 40 g.
What actually changes the number
Packet cookies are 492 kcal per 100 g, about 80 kcal each for a 16 g biscuit. Bakery cookies are 70–100 g and 350–500 kcal — the size, not the recipe, is the whole difference.
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 chocolate chip cookie 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.
