Editorial standards
The MacroCalculators Editorial Team develops and maintains the calculators and educational content published on MacroCalculators.com.
Our work focuses on making nutrition and fitness calculations easier to understand while explaining the formulas, assumptions, references, and limitations behind each result.
We research calculator formulas, review supporting information, explain calculations in practical language, and keep published content updated as references and methodologies change.
We explain how each calculation works, including its formulas, inputs, assumptions, and how results should be interpreted.
We review published material for accuracy, clarity, outdated information, and broken references, and update content when appropriate.
We aim to make the information behind each result reliable, understandable, and useful in context.
We aim to base formulas and important nutrition claims on established research, scientific publications, government resources, and recognized professional organizations.
Calculator results should be understandable. We explain the underlying calculation without unnecessary technical language.
We explain assumptions and limitations rather than presenting nutrition and body-composition calculations as precise measurements.
We explain what a number represents, how it was calculated, and how it fits into the broader context of nutrition and fitness.
Our calculators and educational content focus on connected aspects of nutrition and fitness.
Daily macro, protein, carbohydrate, and dietary-fat calculations.
Calorie needs, basal metabolic rate, total daily energy expenditure, and calorie-deficit calculations.
Body-fat percentage and lean-body-mass estimation.
Each calculator page includes references relevant to its formulas, methodology, and educational content.
Depending on the calculator, sources may include peer-reviewed research, government nutrition resources, academic publications, and established professional organizations.
Where a formula or important claim comes from a specific source, the relevant calculator page should identify that source.
MacroCalculators provides educational estimates, not laboratory measurements or individualized medical advice.
Calculator results depend on the formulas, assumptions, and information used. Different methods can produce different results, so we explain methodology and limitations wherever they are relevant.
Users with medical conditions, medically prescribed diets, or circumstances requiring individualized nutrition guidance should consult an appropriately qualified healthcare professional.
