Editorial Standards

Every factual claim in a NoGymLab article or tool is sourced to primary literature: PubMed-indexed research papers, ISSN position statements, and peer-reviewed nutrition or exercise science journals. We do not cite secondary summaries, general-interest health websites, or press releases in place of original studies.

Sources are cited inline with numbered superscripts and linked directly to the original paper or statement in each article's Sources section. Where a DOI is available, it is included. We do not paraphrase findings beyond what the cited study supports.

For calculation tools, we document the specific formula used (for example, Mifflin-St Jeor for resting metabolic rate, Harris-Benedict for activity-adjusted TDEE) and link to the publication that validated it. Formula choice and its limitations are explained in the accompanying methodology page.

NoGymLab content is written by two authors, each responsible for a distinct topic area:

Sophie Laurent Nutrition Scientist & Sports Dietitian Covers nutrition and metabolic health — calorie deficits, macronutrient tracking, BMI and body composition, intermittent fasting, and metabolic adaptation. View full profile →

Marco Bellini Strength & Conditioning Coach Covers training and movement — bodyweight progressions, calisthenics, dumbbell execution, home workout programming, mobility, and injury prevention. View full profile →

Author pages include each writer's areas of focus, the methodology they apply, and their public profiles. We do not inflate contributor roles or claim credentials that have not been independently verified.

Before publication, each article is read by the other author — Sophie reviews training content, Marco reviews nutrition content. The reviewer checks:

• Whether all cited sources support the claims made in the article
• Whether the formula or protocol described matches the cited methodology
• Whether any claim requires a stronger or more specific source
• Whether limitations or caveats are accurately stated

The reviewer is credited as a contributor on the article front matter. This role does not imply endorsement of every sentence — it means the cited evidence was checked before publication.

Articles display a Last reviewed date in the front matter. When a study we cite is retracted or significantly contradicted by subsequent research, we update the article and note the change at the bottom of the page with a dated correction notice.

If you find an error — a miscalculation, a misquoted figure, a broken citation link, or a factual claim that cannot be verified against its source — use the contact details below. Corrections are prioritised over new content.

Tool formulas are versioned. When a formula is updated (for example, a revised activity multiplier table), the previous version and its deprecation date are documented in the methodology page.

• Unsupported health claims. We do not publish claims about disease treatment, cure, or prevention that are not backed by peer-reviewed evidence or established clinical guidelines.
• Sponsor-driven content. We do not publish articles, tool recommendations, or product placements paid for by a third party without explicit disclosure. Undisclosed sponsored content does not appear on NoGymLab.
• Credential inflation. Authors are introduced by their areas of focus and working methodology, not by claimed titles, licenses, or institutional affiliations that have not been independently verified.
• Extrapolation beyond the evidence. Where a study applies to a specific population, training age, or dietary context, we note that scope rather than generalising the result to all readers.
