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 oatmeal cookie (shop-bought) the split is:
- Protein: 6.2 g × 4 = 25 kcal — 5% of calories
- Carbohydrates: 68.7 g × 4 = 275 kcal — 59% of calories
- Fat: 18.1 g × 9 = 163 kcal — 35% of calories
- Most of the energy in oatmeal cookie (shop-bought) comes from carbohydrate (59% of calories).
- For 200 kcal you can eat about 45 g.
What actually changes the number
Oatmeal cookies are 450 kcal per 100 g — marginally under chocolate chip, and the oats do not make them health food. A packet cookie is about 65 kcal.
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 oatmeal 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.
