Source Selection Policy

Sources we cite

• Peer-reviewed primary research and randomised controlled trials.
• Systematic reviews and meta-analyses.
• Clinical guidelines and statements from recognised bodies (e.g. major endocrine, obesity, and public-health organisations).
• Regulatory records (e.g. FDA/EMA approvals and labelling) for drug facts.
• Established reference databases (PubMed, journal records) for verification.

Sources we avoid as primary evidence

• Press releases and marketing material used as the sole source for a claim.
• Predatory or non-peer-reviewed journals.
• Anecdote, testimonial, or social media presented as evidence.
• Secondary articles standing in for a primary study we have not read.

Recency and provenance

We prefer the most current high-quality evidence while still citing the foundational papers that established a finding. Every source is identified specifically — author, journal, year, and a resolving identifier — so readers can verify it themselves. See our fact-checking policy.
