About HumanFuelGuide
An evidence-based publication covering fitness nutrition, supplementation, training tools, and applied performance strategy.
What we cover
HumanFuelGuide publishes long-form, research-backed guides across four domains: nutrition guides (energy balance, macronutrients, timing), tools (calorie trackers, wearables, training software), supplements (creatine, protein, micronutrients, ergogenic aids), and strategy (programming for specific goals, lifestyles, and constraints).
Editorial standards
Every article is grounded in primary research where it exists. We prioritize systematic reviews, meta-analyses, and randomized controlled trials indexed on PubMed and the Cochrane Library over secondary commentary. Where evidence is preliminary, contested, or absent, we say so plainly rather than overstating confidence.
Recommendations are revised when new evidence emerges. Articles carry a visible published and last-updated date, and material reversals are documented in the article’s changelog.
How we test products
Tools, apps, and supplements undergo a 30–90 day in-house evaluation window. For calorie trackers, food databases are spot-checked against USDA FoodData Central. For supplements, we verify third-party batch testing (Informed Sport, NSF Certified for Sport, USP) before issuing a recommendation.
Editorial independence
HumanFuelGuide does not accept paid placements, sponsored rankings, or supplement-industry partnerships that influence editorial. Where affiliate links are used, they are disclosed and never determine which products earn a recommendation. We routinely recommend products from which we earn nothing when the evidence supports them.
Editorial team
HumanFuelGuide is produced by an independent editorial team of writers and reviewers with backgrounds in nutrition science, exercise physiology, and applied sports performance. Author bylines are added to articles as the site’s contributor program expands.
