Editorial responsibility
Yanhua Yang, Founder & Editor of Everyday Body Guide, is responsible for editorial direction, source research and organization, content editing, calculator and tool development coordination, corrections, updates, and site maintenance. The public editorial contact is available on our Contact page and is monitored for substantive corrections.
Yanhua is not a physician, registered dietitian, or licensed healthcare professional. Her authorship and editing do not represent clinician review. We do not attach a clinician's name or credentials to content unless that individual actually reviewed the page and the relevant credentials were verified.
Source hierarchy
For health recommendations and population reference values, we prefer current guidance from public-health agencies, government health institutes, national academies, and established professional organizations. For formulas and questions that require underlying evidence, we prefer original peer-reviewed research or systematic reviews.
A source is not included merely because it supports a convenient claim. We check whether it applies to the population and outcome being discussed, distinguish measured findings from predictions, and disclose material limitations. Individual guides list the sources used for their substantive claims.
Calculators and worked examples
Before publishing a calculator, we document its equation, units, accepted input range, rounding behavior, and known limitations. We test representative and boundary inputs and compare worked examples with an independent calculation. Outputs are labelled as estimates when the method predicts rather than measures a value.
A calculator result is not converted into a diagnosis or individualized treatment recommendation. Where published equations use sex-specific coefficients or broad activity categories, we explain that limitation rather than presenting the model as universal.
Writing and originality
Each page begins with a defined reader question and should add a useful explanation, worked example, comparison, or decision aid. We avoid changing only the wording of a source. Common site elements such as references and medical notices are consistent, while the central explanation should reflect the needs of that specific topic.
Automated tools may assist routine production tasks, but they do not replace source checking, calculation testing, editorial responsibility, or the requirement to publish accurate and useful original material.
Corrections and meaningful updates
Reports sent to contact@everydaybodyguide.com should identify the URL and the possible error. We assess the cited evidence, correct material errors, and revise related pages when the same issue appears elsewhere.
We update the displayed date for a substantive change to evidence, calculations, interpretation, or safety boundaries. Spelling, layout, and other cosmetic changes do not by themselves receive a new substantive update date.
Independence and commercial disclosure
Editorial conclusions are not purchased by an advertiser or sponsor. The site currently includes the Google AdSense ownership-verification script but does not display ad units. If advertising or sponsorship is introduced, it will be visually distinguished and will not permit an advertiser to alter a health conclusion.
Health content boundaries
Our content is general education, not personal diagnosis, treatment, prescribing, emergency care, or a clinician–patient relationship. Symptoms, medical conditions, medications, pregnancy, eating-disorder concerns, and individual nutrition or fluid restrictions require appropriate professional care.
