Editorial Guidelines

Calora publishes health-adjacent tools, so accuracy and honesty matter to us. These guidelines describe how our calculators and educational content are created, reviewed, and maintained.

Evidence-based formulas

Our calculators rely on established, peer-reviewed equations rather than proprietary guesswork:

• BMR — the Mifflin–St Jeor equation, widely regarded as one of the most accurate predictive formulas for the general population.
• TDEE — BMR multiplied by standard activity factors (1.2 to 1.9).
• Body-fat-based needs — the Katch-McArdle equation, which estimates metabolism from lean body mass.
• Weight projections — the widely used approximation of 7,700 kcal per kilogram (about 3,500 per pound) of body mass.

Accuracy and safety

Every calculator is tested against worked examples to confirm the math is correct. We build in safety floors — our tools will not recommend eating below 1,200 calories per day for women or 1,500 for men — and we clearly flag when a result has been adjusted for safety.

Clear, non-sensational writing

We aim for plain, practical language and avoid fad claims, miracle promises, or fear-based messaging. Where a topic is genuinely uncertain, we say so and frame results as estimates and starting points, not guarantees.

Not medical advice

Our content is educational and is not a substitute for professional medical or nutritional advice. We consistently encourage readers with specific health circumstances to consult a qualified professional.
