⚕️ Not a Substitute for Medical Advice
The content on FitFuel Tools, including all calculator results, articles, and information, is provided for general informational and educational purposes only. It is not intended to be medical advice and must not be treated as such.
Informational Purposes Only
FitFuel Tools provides health and nutrition calculators based on well-established scientific formulas used in public health and research contexts. These tools produce estimates — not diagnoses, prescriptions, or clinical measurements. Individual results will vary based on factors our calculators cannot account for, including but not limited to genetics, medical history, medications, and metabolic conditions.
Always Consult a Professional
Before making any changes to your diet, exercise routine, supplementation, or lifestyle based on information from this Site, you should consult a qualified healthcare professional, such as:
- A licensed physician or general practitioner
- A registered dietitian or nutritionist
- A certified personal trainer or exercise physiologist
- A specialist relevant to your specific health condition
Do not disregard or delay seeking professional medical advice because of anything you read or calculate on this Site.
No Doctor-Patient Relationship
Use of FitFuel Tools does not create a doctor-patient, dietitian-client, or any other professional healthcare relationship between you and FitFuel Tools or any of its team members.
Emergency Situations
If you are experiencing a medical emergency, chest pain, difficulty breathing, or any other serious health event, call your local emergency services immediately (911 in the US, 999 in the UK, 112 in the EU). Do not rely on this website in an emergency.
Limitation of Liability
FitFuel Tools and its owners, authors, and contributors accept no responsibility or liability for any loss, damage, or harm — including health consequences — that may result from your use of or reliance on any information or calculator result provided on this Site. See our full Terms of Use for complete details.
Formula Sources
Our calculators are built on peer-reviewed, published scientific formulas including the Mifflin-St Jeor equation (1990), the US Navy circumference body fat method (Hodgdon & Beckett, 1984), and WHO BMI classification standards. The use of published formulas does not mean our results constitute medical advice — even clinically validated tools are estimates when used outside a supervised clinical setting.
