Editorial Policy

HealthyLifeStyles publishes free health calculators and educational guides. This policy explains how that content is created, sourced, reviewed, and kept up to date — and where our money comes from — so you can judge how much to trust it.

Who creates our content

Content is produced by our editorial team and checked by our medical review board. We do not publish AI-generated articles as finished work, and we do not invent author names or credentials. As we add named, credentialed reviewers, their profiles and qualifications will appear on their author pages.

How we research and write

• We start from primary, authoritative sources — peer-reviewed studies and guidance from bodies such as the CDC, WHO, NIH, ACOG, the American Heart Association, and registered professional organizations.
• Every calculator uses an established, published formula. The exact equations and their sources are documented on our methodology page.
• We write in plain language, hedge where the science is uncertain, and avoid sensational or absolute health claims.
• We do not fabricate statistics, testimonials, or “as used by” endorsements.

Medical & accuracy review

Health-related tools and articles are reviewed for clinical accuracy, safe framing, and appropriate disclaimers before they publish. The reviewer and the review date are shown in the byline on each page (“Medically reviewed by …, Updated …”). Reviewers are licensed clinicians & registered dietitians.

Sourcing & citations

Articles list their sources in a “Reviewed & sources” section, and tool pages include a “Sources & references” list. We link directly to the original research or guidance wherever possible so you can verify it yourself.

Independence, ads & affiliates

• Editorial decisions are independent of advertising and affiliate relationships.
• Some pages display ads or include affiliate links; affiliate links are disclosed where they appear, and we may earn a commission at no extra cost to you.
• A product being recommended is never contingent on a commercial relationship — recommendations reflect relevance to the tool, not who pays us.

Corrections & updates

We revisit content as the evidence changes and correct errors promptly. Each page shows when it was last updated. If you spot a mistake, please tell us at hello@healthylifestyles.com and we’ll review it.
