Carnivore Macro Calculator
Pick a cut, enter a weight, and get protein, fat, and calorie totals. The Carnivore Macro Calculator works for raw or cooked weights and covers 30+ common carnivore cuts across beef, pork, lamb, poultry, seafood, eggs, and cooking fats. Macro values are USDA FoodData Central per-100g-cooked figures. For raw weight inputs the calculator applies a 25% cooking loss (typical for muscle meat) before computing macros. For higher-fat cuts that lose more weight during cooking (pork belly, short ribs), the result is a slight under-estimate; for lean cuts (eye of round, chicken breast), it lands within 5% of real-world cooked yield. Most carnivore eaters target 30 to 60g of protein and 25 to 50g of fat per meal, which corresponds to roughly 6 to 8 oz of cooked ribeye, 10 oz of cooked sirloin, or 4 to 5 large eggs plus 2 tbsp of butter. The calculator is free, runs entirely in the browser, and stores nothing.
Raw weight assumes ~25% loss during cooking. Switch to “Cooked” if you're weighing meat after it comes off the heat.
8 oz of ribeye (raw) → ~6 oz cooked

How to use this
- For meal planning: Pick the cut you bought, enter the package weight (raw), see how many servings it yields and what each one delivers.
- For tracking: Weigh the cooked portion on your plate, switch to “Cooked”, and copy the macros into your tracker (or use Carnivore Max, which logs cuts directly from text).
- For shopping comparison: Compare two cuts head-to-head — e.g. 8 oz ribeye vs 8 oz sirloin — to see the protein/fat/calorie tradeoff before you decide which to buy.
