Editorial Policy

FitFixLife is committed to publishing accurate, evidence-based health and fitness content. This page explains how we create and maintain our content.

Our Approach

Every piece of content on FitFixLife — whether it is a calculator, article, or guide — is built on the same principle: evidence first. We do not publish claims we cannot support with credible sources.

Calculator Methodology

All calculators on FitFixLife use named, peer-reviewed formulas. We do not use proprietary or unverifiable equations. Each tool page identifies the specific formula used and provides citations. Formulas we use include:

• Mifflin-St Jeor (1990) for calorie and BMR calculations
• Harris-Benedict (1918) as an alternative BMR formula
• Katch-McArdle for BMR when lean body mass is known
• WHO Body Mass Index classification for BMI
• Institute of Medicine Dietary Reference Intakes for macros
• Phillips & Van Loon (2011) for protein recommendations
• EFSA (2010) for water intake guidelines
• Epley (1985) for one-rep max estimation
• National Sleep Foundation guidelines for sleep
• Hodgdon & Beckett (1984) U.S. Navy method for body fat

Article Standards

• Minimum 3 credible sources per article
• Sources include: PubMed, NIH, WHO, NASM, peer-reviewed journals, and established medical/scientific institutions
• We do not cite social media, forums, or unverified sources as primary evidence
• Articles are reviewed for factual accuracy before publication
• We use careful, hedged language (e.g. “research suggests”, “may help”) and never make absolute health claims

Trusted Sources

• PubMed (National Library of Medicine)
• National Institutes of Health (NIH)
• World Health Organization (WHO)
• National Academy of Sports Medicine (NASM)
• American College of Sports Medicine (ACSM)
• International Society of Sports Nutrition (ISSN)
• Peer-reviewed journals in nutrition and exercise science
