An 8-oz cooked Angus steak delivers ~500–600 calories, ~50 g protein, and rich B12, iron, and zinc; fat shifts by cut and cooking.

What You Get From A Serving
Start with the numbers that matter at the table. A 6–8 oz cooked portion lands near 45–55 grams of complete protein with all the essential amino acids. Calories swing with marbling and trim. Leaner cuts sit lower; richly marbled steaks climb. Micronutrients pack a punch too: B12 supports red blood cell formation, zinc aids immune function, and heme iron is well absorbed.
Beef’s protein quality is high, so smaller servings still satisfy. Pair a palm-size portion with vegetables and a starch to round out fiber and potassium. If you’re chasing muscle gain, scale the portion, but track the fat that rides along with thicker steaks.
Angus Steak Nutrients Breakdown (Per 100 Grams)
Numbers below reflect cooked meat without sauces. The spread across cuts mostly tracks with fat. Breed alone doesn’t change macros; cut, grade, and trimming do. Use this snapshot to match a cut to your goal.
| Cut | Calories | Protein/Fat (g) |
|---|---|---|
| Top Sirloin | ~188 | Protein ~30 • Fat ~6.6 |
| Ribeye | ~186 | Protein ~29.4 • Fat ~7.6 |
| Tenderloin | ~197 | Protein ~30.3 • Fat ~8.3 |
Those ranges come from lab-based entries used by dietitians and meal-planning tools. If you buy a thicker fat cap or a higher marbling grade, the fat number climbs and so do calories. Trimming and cooking method nudge totals too, since rendered fat may stay in the pan.
How Breed, Grade, And Cut Interact
Angus describes the cattle breed. USDA quality grades like Prime, Choice, and Select are separate; they track marbling and predict tenderness and juiciness. A ribeye from any breed with more intramuscular fat will read higher in calories than a tightly trimmed sirloin. In short: pick the cut for your goal—lean for lighter meals, marbled for flavor-forward nights.
Protein Quality And Amino Acids
Steak delivers a dense amino acid mix with standout leucine, lysine, and valine—handy for muscle repair after training. Most people hit protein targets easily with mixed meals, so think about variety across the day instead of loading one giant portion at dinner.
Micronutrients That Stand Out
Vitamin B12 often runs several micrograms per 100 g, easily meeting daily needs for adults. Beef also supplies heme iron and substantial zinc, plus selenium. These are helpful nutrients for energy metabolism and normal immune function. If you eat little or no meat, consider fortified foods to cover the same bases.
Portion Math For Real Plates
Here’s a quick way to estimate a meal without a scale. Cooked weight is roughly 70–75% of the raw steak after trimming and resting. A deck-of-cards piece is close to 3–4 oz cooked. Double that for a big night. Marbling drives calorie spread, so the same size ribeye and sirloin won’t match on fat.
| Portion Size | Lean Cut (Sirloin) | Marbled Cut (Ribeye) |
|---|---|---|
| 4 oz | ~180 kcal • ~28 g protein | ~175–200 kcal • ~27–29 g protein |
| 6 oz | ~270 kcal • ~42 g protein | ~265–300 kcal • ~40–44 g protein |
| 8 oz | ~360 kcal • ~56 g protein | ~355–400 kcal • ~53–58 g protein |
If you track macros, round to the nearest 5 grams and keep the plate balanced with fiber-rich sides. That keeps the meal satisfying without piling on unplanned energy.
Cooking Method Tips That Shape Macros
Grill Or Broiler
High heat hard-sears the surface and can drip some fat away. Use a two-zone setup so the center reaches doneness without scorching. Rest on a rack to leave more rendered fat behind.
Cast-Iron Sear
A hot pan builds a deep crust fast. Use a teaspoon of oil; the steak brings its own. Spoon rendered fat over the top for flavor, then blot before serving if you’re watching calories.
Sous Vide + Sear
This route cooks edge-to-edge, then finishes with a quick crust. It’s forgiving for tenderloin and thicker sirloin where you want tenderness without overcooking.
Smarter Choices At The Store
Pick The Cut For The Job
For weeknights, top sirloin and eye of round keep calories tidy with plenty of protein. When flavor takes center stage, a ribeye or strip steak delivers rich bite and a wider fat band.
Check The Grade, Not Just The Label
“Angus” signals breed, while USDA grades signal marbling. Choice usually means more intramuscular fat than Select. If you want a leaner eat, look for Select or a clearly trimmed cut. If you chase a buttery texture, upper-Choice and Prime bring it.
Watch The Portion
Many restaurant steaks hit 10–14 oz cooked. Share, box the extra, or order a smaller cut. Your protein target will still be covered, and you’ll keep the calorie bill in line.
Nutrients To Know: B12, Iron, Zinc
B12 in steak can meet the daily target in a single serving. Iron shows up in heme form, which the body absorbs well. Zinc supports normal immune function and wound repair. That mix makes steak a solid nutrient contributor inside a varied diet built on plants, dairy, and other proteins.
You’ll see labels like “lean” or “extra-lean” on some packages. Those terms have specific thresholds for total fat, saturated fat, and cholesterol per 100 g cooked. If that matches your goals, look for those words on the label, or choose naturally lean cuts like sirloin. For definitions used on labels, see the extra-lean criteria.
Make It A Balanced Meal
Protein and fat carry the steak. Round out the plate with a starchy side and a pile of vegetables to add fiber, potassium, and volume. That mix steadies appetite and helps keep sodium in check if you season generously.
Simple Pairings That Work
- Sirloin with roasted potatoes and a bright salad
- Tenderloin with herbed rice and sautéed greens
- Ribeye with grilled corn and tomato-cucumber salad
Frequently Asked Nutrition Swaps
Trim, Don’t Drown
Skip heavy butter baths and creamy sauces if you’re trimming calories. A squeeze of lemon, chopped parsley, and a drizzle of pan juices keep flavor sharp without pushing fat grams up.
Plan Red-Meat Days
Steak fits best alongside poultry, seafood, legumes, and dairy across the week. Rotate proteins so you hit a variety of nutrient profiles while keeping saturated fat in check.
Label Clues That Matter
Lean And Extra-Lean Definitions
“Lean” means less than 10 g total fat, 4.5 g or less saturated fat, and under 95 mg cholesterol per 100 g cooked. “Extra-lean” drops total fat under 5 g with saturated fat under 2 g in the same amount. If the package doesn’t list trim level, the cut name usually hints at it: round and sirloin tend to be leaner than rib or short loin.
Raw Weight Vs. Cooked Weight
Raw steaks lose moisture and some fat during cooking. Expect a 25–30% drop in weight after resting. If you log meals, base entries on cooked weight for consistency.
Putting It All Together
Pick the cut for your goal, set a sensible portion, and cook with a light hand. With those three levers, you can get the protein and minerals you want without overshooting calories. That’s the sweet spot where steak fits cleanly in an everyday diet.
