Editorial Standards

Purpose and independence

FitCalc is independently built and run. It does not claim to have a physician review board, large editorial department, or credentials that do not exist. Calculator methods and Journal articles aim to make fitness and nutrition information practical while being clear about uncertainty and limitations.

Evidence hierarchy

When a claim depends on scientific evidence, FitCalc generally gives greater weight to:

1. Systematic reviews and meta-analyses
2. Credible guidelines and professional position stands
3. Peer-reviewed primary studies
4. Government and academic references

Not every question has perfect evidence, and study quality, population, methods, and relevance still matter. Competitor sites, marketing pages, and unsourced blog claims are not treated as scientific evidence.

Calculators and recommendations

Calculator equations, assumptions, limitations, sources, and review dates are documented on How FitCalc Calculators Work. A calculated result is a mechanical formula output. An evidence-based range reflects research or recognized guidance. A FitCalc recommendation is a practical interpretation.

FitCalc may recommend a target that is different from the minimum supported by research. When it does, that choice should be described as a FitCalc recommendation rather than disguised as a universal scientific fact.

Authorship and transparency

FitCalc content should identify its purpose and avoid manufactured authority. Sources should link to the underlying research, guideline, government, or academic material where practical. Publication and update information should not be changed merely to make content appear newer.

If sponsored or affiliate content is introduced later, the relevant commercial relationship should be disclosed where readers encounter it. This statement does not imply that such a program currently exists.

Health limitations

Fitness and nutrition information on FitCalc is educational. Calculators estimate; they do not diagnose disease, replace laboratory assessment, or provide individualized medical care. Readers should use appropriate professional care for symptoms, medical conditions, pregnancy, eating-disorder concerns, medication decisions, or other situations requiring individualized advice.

Corrections and updates

If a formula, citation, or factual statement is wrong, FitCalc aims to correct it and update the relevant review or modification information when appropriate. New evidence may also justify revisiting an explanation or recommendation.
