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 hamburger (single, plain) the split is:
- Protein: 16.5 g × 4 = 66 kcal — 22% of calories
- Carbohydrates: 31.5 g × 4 = 126 kcal — 42% of calories
- Fat: 12 g × 9 = 108 kcal — 36% of calories
- The energy in hamburger (single, plain) is spread fairly evenly across protein, carbohydrate and fat.
- With 16.5 g of protein per 100 g it counts as a high-protein food.
- That is 5.6 g of protein per 100 kcal — a useful number when protein is your target.
- For 200 kcal you can eat about 65 g.
Compare preparations
The same food, prepared differently. Cooking removes water (so calories per 100 g rise), adds fat (so they rise further), or both.
| Preparation | Calories | Protein | Carbohydrates | Fat |
|---|---|---|---|---|
| Hamburger (single, plain)this page | 297 | 16.5 g | 31.5 g | 12 g |
| Cheeseburger (single, plain) | 308 | 16.5 g | 28 g | 14.7 g |
| Double cheeseburger (double, with condiments) | 282 | 16.2 g | 18 g | 16.2 g |
What actually changes the number
A plain fast-food hamburger is about 270 kcal — a small patty and a bun. The number climbs fast with size and additions: a quarter-pound patty adds 150, cheese 50 per slice, mayonnaise-based sauce 90 per tablespoon.
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 hamburger 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.
