- Carbohydrates: 0 g × 4 = 0 kcal — 0% of calories
- Fat: 6.6 g × 9 = 59 kcal — 33% of calories
- Most of the energy in sirloin steak (lean, grilled) comes from protein (67% of calories).
- With 30.3 g of protein per 100 g it counts as a high-protein food.
- That is 16.1 g of protein per 100 kcal — a useful number when protein is your target.
- For 200 kcal you can eat about 105 g.
What actually changes the number
Trimmed sirloin is 188 kcal per 100 g cooked and one of the leaner steaks. A restaurant 8 oz steak weighs around 170 g after cooking — about 320 kcal — but the visible fat cap, if eaten, can add a further 100.
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 sirloin steak 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.
