How many calories are in standard steak sizes (6 oz, 8 oz, 12 oz, 16 oz)?

For a standard Choice NY Strip: 6 oz = ~390 kcal (36g protein, 25g fat); 8 oz = ~520 kcal (48g protein, 34g fat); 12 oz = ~780 kcal (72g protein, 51g fat); 16 oz = ~1,040 kcal (96g protein, 68g fat).

How much does bone weight reduce the actual edible calories in a T-Bone or Porterhouse?

A T-bone contains ~15% to 20% bone weight, while a large Porterhouse contains ~18% to 22% bone. In a 20 oz Porterhouse, approximately 4 oz is non-edible bone, leaving 16 oz of edible tenderloin and strip meat.

How much edible cooked meat do you get from a 16 oz raw steak?

A 16 oz boneless steak typically loses ~25% moisture during medium-rare cooking, yielding approximately 12 oz of cooked steak. The protein and fat remain identical to the 16 oz raw state.

Which steak size and cut offers the highest protein with the lowest calories?

An 8 oz raw top sirloin or filet mignon provides ~50g to 54g of protein for only ~360 to 440 calories, compared to an 8 oz ribeye which delivers ~550 to 660 calories.

Why do thicker 2-inch steaks retain more moisture than thin 0.75-inch steaks?

Thick-cut steaks have a lower surface-area-to-volume ratio. High cooking heat only affects the outer perimeter, preserving the central core moisture and yielding ~78%–82% cooked weight compared to ~70% for thin steaks.

How do restaurant steak ounces compare to raw butcher shop weights?

Restaurant menus list the raw (pre-cooked) weight of the steak unless specifically stated otherwise. A '12 oz ribeye' on a menu will arrive on your plate weighing approximately 9 to 9.5 oz cooked.

Scaling Primal Calorimetry: Portion Sizing & Yield Dynamics

Whether preparing a petite 6 oz Filet Mignon or a celebratory 32 oz Tomahawk Ribeye, accurately calculating caloric intake requires scaling for raw butcher weight, bone deduction percentages (15%–35%), and thermal moisture loss (~20%).

As steak portion sizes increase, total lipid mass and bone thermal buffering scale non-linearly. Thick 2-inch primal cuts store significant thermal momentum during cooking, resulting in a higher post-heat carryover rise (+8°F to +12°F) compared to thinner steaks (+3°F to +5°F).

Linear Scaling vs Trim

Protein scales strictly linearly with portion weight (~6g protein per raw ounce), while fat calories vary based on seam fat trimming.

Bone In Weight Offset

T-bone, Porterhouse, and Tomahawk steaks contain 15%–35% non-edible bone mass that must be subtracted before macro calculations.

Cooked Plated Yield

Cooking to medium-rare produces an average 80% yield of plated edible meat from raw weight due to clean water evaporation.

Frequently Asked Questions: Steak Sizing & Macros

How should I portion steak if I'm eating one meal a day (OMAD)?

For carnivore or OMAD practitioners, a single 16 oz to 24 oz 100% grass-fed steak provides 100g–140g of protein, ~1,000–1,500 clean calories, and a complete daily dose of essential micronutrients (iron, zinc, B12, carnosine).
