Raw or cooked: weighing food without fooling yourself
Raw or cooked: weighing food without fooling yourself: rice roughly triples, chicken loses about a quarter, and the calorie figure somebody looked up…
This launch guide maps the topic, the source base and the practical questions. Check the linked official authority before acting on a rule, deadline, price or safety requirement.
What this guide covers
Rice roughly triples, chicken loses about a quarter, and the calorie figure somebody looked up belongs to only one of those states — which is why this is asked constantly and answered badly.
A page per food and method gives the official yield factor, the conversion in both directions, and the nutrient retention factor for the vitamins genuinely lost in the pot: rice, pasta, potatoes, oats, dried legumes, chicken breast and thigh, beef mince at each fat level, pork, fish, mince browned and drained, bacon, and vegetables boiled, steamed and roasted. Around forty food-by-method pages plus one converter.
How to use it
Use Raw or cooked: weighing food without fooling yourself as a structured learning path: begin with the vocabulary, follow the evidence map, and keep the uncertainty labels attached to claims as you compare sources.
The page keeps the main question, its evidence base and its limits together in one canonical place. That makes it useful as a quick orientation and avoids splitting a broad subject into shallow pages before each narrower answer has enough verified material of its own.

Evidence and provenance
The evidence map below records the primary, official or openly licensed material chosen for this guide. It is deliberately visible so a reader can tell the difference between a rule published by an authority, a measured dataset and an editorial explanation.
Source: the USDA Table of Cooking Yields for Meat and Poultry and the USDA Table of Nutrient Retention Factors Release 6, both US public domain, computed against the apex food database. · checked 2026-09-09
Source names are preserved even where an authority changes its web address. No figure is added to this launch page unless it is already present in the cited source description or can be computed from a named dataset.
Scope and boundaries
/cooking gives times and temperatures; this is only the arithmetic of weight change and nutrient loss.
