Editorial Policy

How CaloriePro researches, writes and checks its calculators and guides.

Who We Are

CaloriePro is an independent website of free calorie, nutrition and body-composition calculators. Our guides are written by the CaloriePro Editorial Team. We are not a medical practice, and nothing on this site replaces advice from a doctor or registered dietitian.

Where Our Information Comes From

We base every calculator and guide on primary, authoritative sources:

• public health bodies such as the NHS, the World Health Organization, the National Institutes of Health and the Dietary Guidelines for Americans;
• peer-reviewed research and position stands, cited by journal and linked to the PubMed record where possible;
• official regulations, such as the energy conversion factors used on food labels.

We do not cite blogs, forums or other calculator sites as evidence. Each guide lists its sources at the end, and every number in a guide can be traced to one of them.

How We Write and Check

• We read each source in full before writing, and write in our own words.
• Figures, ranges and formulas are checked against the source, and worked examples are recalculated before publishing.
• Where the evidence is uncertain or experts disagree, we say so instead of picking a side.
• Our calculators use the same published formulas our guides describe, and each calculator page explains its method.

Updates and Corrections

We review guides when guidance or research changes. A guide's "Updated" date shows when it was last checked or changed. If we find an error, we correct it and update that date.

Advertising and Independence

CaloriePro does not sell diets, supplements or coaching, and no company pays to appear in our guides. We use Google Analytics to understand which pages are used.
