Cooking planning
Ribeye changes quickly with doneness because of cooking loss, so a raw-to-cooked reference is useful for portion logging.

Informational journaling tool
Log ribeye calories, protein, fat, iron, zinc, and B12 from one shared boneless raw reference, then translate that portion into a cooked-weight planning estimate by doneness.
Log one stable ribeye reference with raw-to-cooked portion math.
Premium grade and feed differences are shown as context below. The main calculator stays on one shared baseline so the numbers remain easier to audit and compare over time.
150g raw finishes around 120g cooked at 20% shrinkage.
Cooking method is intentionally not formula-switched here. This page uses doneness-based portion math only.

Beef contains both heme and non-heme iron, but the exact split changes across cuts, samples, and study methods. This tool logs total iron instead of showing a personalized retained-iron estimate.
How to read this: The main numbers come from one boneless raw ribeye baseline in the shared site dataset. Premium grade and feed notes are context only, and trim-aware logging is intentionally held until the ribeye-specific trimmed reference is mapped cleanly.
Ribeye changes quickly with doneness because of cooking loss, so a raw-to-cooked reference is useful for portion logging.
Ribeye usually runs higher in calories and fat than sirloin or flank, which makes it a useful richer benchmark cut.
Feed type and grade can shape marbling and buying context, but this page keeps those differences separate from the main journaling math.
The ribeye page keeps one stable raw-reference baseline and separates comparison context from the main journaling math.
The calculator uses one boneless raw ribeye reference from the site's central beef data model. That shared dataset is maintained from USDA FoodData Central source records, and the same baseline drives the client, page copy, and exports.
Raw-to-cooked translation uses doneness-based shrinkage only. Cooking method is intentionally not formula-switched here because the current page does not have a clean ribeye-specific method model for every setup.
Grade and feed differences are still useful for comparison, but they are shown as context notes instead of arbitrary multipliers. Trim-aware ribeye logging stays out of the main formula until the trimmed reference is mapped cleanly enough to trust.
Last reviewed: March 2026. This tool is for informational and journaling use only. It keeps total iron as the logged value and does not attempt personalized retention or absorption outputs.
This page uses one boneless raw ribeye reference that lands around 291 calories per 100g, with portion totals scaling from that baseline.
Raw logging is the clearest starting point because the baseline data is tied to a raw portion. If you only have cooked weight, the calculator estimates a raw equivalent from the selected doneness.
Grade and feed differences are directionally real, but this page keeps one stable baseline in the main math rather than applying guessed multipliers. Premium differences are shown as comparison context instead.
Visible fat trimming can lower the final edible fat and calorie total, but this tool keeps trim-aware logging separate until the ribeye-specific trimmed reference is mapped cleanly enough to trust.
