A calculator is a tool, not a promise.

The site is intended only for adults aged 18 and over who can safely use a general calorie estimate. Do not use it during pregnancy or breastfeeding, for a person under 18, for eating-disorder support, or where a clinician has provided or should provide a medical nutrition plan.

If you have a health condition, concerning symptom, unexplained weight change, medication-related need or uncertainty about whether weight change is appropriate, seek guidance from an appropriately qualified healthcare professional or registered dietitian. Check their credentials with the relevant regulator or professional body in your country or region.

Results depend on the values and activity description entered. They are mathematical estimates, not measurements, and actual needs may differ. A displayed calorie or macro figure is not a guarantee of weight change or health outcome.

Use the range carefully, pay attention to wellbeing and stop if tracking becomes distressing or harmful. Never delay medical help because of information on this site.

Do not misuse the site, attempt to disrupt or bypass its security, submit unlawful material, extract data in a way that harms availability, or present its general output as a clinical assessment of another person. The site may be changed, corrected, suspended or withdrawn when needed for safety, maintenance or compliance.

The rebuild has no user accounts, checkout, subscription, advertising, analytics or affiliate links. Printing, downloading and shopping-list functions operate locally in the browser. If commercial features are introduced, the relevant terms, disclosures and privacy information must be updated before activation.

Reasonable care is taken to keep the tool accurate and available, but uninterrupted operation and error-free results cannot be guaranteed. Nothing in these terms excludes responsibilities that cannot lawfully be excluded. Content may be corrected, changed or withdrawn when evidence, safety or service needs require it.

Read the methodology, editorial policy and privacy notice alongside these terms.
