Our 4-stage editorial pipeline
Research
Every article begins with a literature scan in PubMed and at least three position stands or guidelines from major bodies (ACSM, ISSN, NIH, WHO, CDC). We work backward from the highest-quality evidence: meta-analyses and systematic reviews first, RCTs second, observational studies third, and expert position stands as anchoring frameworks.
Writing
Drafts cite sources inline. Quantitative claims (calorie counts, percentages, multipliers) include the equation or study they came from. Health claims are stated with the appropriate uncertainty (±10% accuracy, individual variation, etc.).
Fact-check
Before publication, every numerical claim is verified against the cited source. Tables (calorie charts, BMR by weight) are generated from the published equations, not summarized from another website.
Review
All guides receive editorial review before publication and are attributed to the editorial team. When an article has been reviewed by a named expert (such as a Registered Dietitian Nutritionist), that reviewer's name and credentials appear at the bottom of the article. Articles without a named reviewer carry only the editorial team attribution.
Sources we trust
We cite primary literature wherever possible. When we summarize a position, we link to the originating organization. We never cite forum posts, social-media claims, or non-peer-reviewed publications as evidence for health claims.
Update cadence
- •Annual review. Every article is re-read and updated at least once every 12 months. The "Last reviewed" date at the bottom of each guide is always the actual most recent review.
- •Evidence-driven updates. When a major position stand is published or revised (for example, an updated ISSN protein recommendation), we revise affected guides within 60 days.
- •Reader-flagged corrections. We respond to correction reports within 7 days. Corrections are made transparently with a date stamp.
