Editorial Policy

Our Mission

GetHealthyCalculators publishes evidence-based health and fitness calculators and educational content. Our goal is to give you clear, honest tools backed by peer-reviewed research — not marketing claims, hype, or pseudoscience. Every calculator is built on a published formula, and every piece of content is written to help you understand, not to sell you something.

Evidence Standards

Every calculator on this site is derived from one of the following sources:

• A peer-reviewed study published in a recognized medical or sports science journal (for example, the Mifflin–St Jeor equation for BMR, or the ADAG formula for estimated average glucose).
• A clinical guideline from a recognized body (ACSM, ADA, NASM, WHO, USDA, NIH, or equivalent).
• A well-documented formula that is widely used in clinical or sports-science practice, with its limitations called out in the calculator's own interpretation copy.

Where evidence is limited, conflicting, or based on a narrow population, we say so in the calculator's methodology and limitations sections. When we reference a study, we name it — not just “research shows”.

Claim Language

We hold our copy to a specific language standard to avoid overstating what a calculator or a study can tell you:

• We use may, might, and suggests— not “will,” “does,” or “proves.”
• We use correlation and association— not “cause” — unless a specific randomized controlled trial established causation.
• We do not use “clinically proven,” “doctor recommended,” “medically approved,” or “FDA approved” unless it is literally true and we can link the source.
• We do not claim any tool, formula, or practice will diagnose, treat, cure, or prevent any disease.

Authors and Reviewers

Calculator content is written by the GetHealthyCalculators editorial team. Where relevant, a calculator or article surfaces a named reviewer with credentials (for example, RDN, CSCS, MD, PhD) and the date of the last review. That metadata lives in the calculator's content file and is rendered on the page so you can see who checked it and when.

We do not fabricate credentials, attribute content to non-existent reviewers, or imply oversight that did not happen.

Review and Update Cadence

Every calculator content file carries a lastReviewed date. We prioritize reviewing:

• High-traffic calculators (BMI, TDEE, calorie, protein, macros).
• Calculators covering rapidly evolving topics (GLP-1 protocols, peptides, emerging training protocols).
• Calculators whose underlying formula has been superseded or substantially revised in the literature.

When an update changes the formula or the interpretation copy, we revise the lastReviewed date and note what changed.

Editorial Independence

Our editorial content is created independently. We do not accept payment to feature, review, or rank specific supplements, apps, programs, or products. GetHealthyCalculators does cross-link to sister sites in our own portfolio (LiftProof, Prova, PeptideWise) where the topic is a genuine fit — those links are never sponsored and are labeled as internal.

If we ever introduce affiliate relationships or sponsored content, we will disclose those relationships inline with the relevant content, in accordance with FTC guidelines.

Corrections

When we identify an error — or when a reader brings one to our attention — we follow this process:

• Minor (typos, broken links, formatting): fixed promptly, no notice.
• Factual (incorrect constants, misquoted studies, wrong formulas): fixed and the lastReviewed date is bumped.
• Significant (new evidence that changes the recommendation, a retracted source): a short correction note is added to the affected page explaining what changed and why.
