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 muffin (blueberry) the split is:
- Protein: 4.5 g × 4 = 18 kcal — 5% of calories
- Carbohydrates: 53 g × 4 = 212 kcal — 57% of calories
- Fat: 16.1 g × 9 = 145 kcal — 39% of calories
- Most of the energy in muffin (blueberry) comes from carbohydrate (57% of calories).
- 31.5 g of its carbohydrate per 100 g is sugar.
- For 200 kcal you can eat about 55 g.
What actually changes the number
A shop muffin is 375 kcal per 100 g and coffee-shop muffins weigh 110–140 g — 400–500 kcal, as much as a slice of cake. The blueberries do not change that.
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 muffin 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.
