Not Medical Advice

The information, calculators, and tools provided on FastBMI.com are strictly for educational and informational purposes only. Nothing contained on this site is intended to be, nor should it be interpreted as, medical advice, diagnosis, or treatment.

1. Educational Purpose Only

FastBMI provides mathematical calculations (such as BMI, TDEE, BMR, and ideal body weight estimations) based on widely accepted public health formulas. These calculations are general screening tools. They are not diagnostic instruments and cannot evaluate your personal health status, medical history, or specific physiological needs.

2. Consult Your Healthcare Provider

You should never delay seeking medical advice, disregard medical advice, or discontinue medical treatment because of information you have read or calculated on this website.

Always seek the advice of your physician, registered dietitian, or other qualified health provider with any questions you may have regarding a medical condition.
Do not start any new diet, fitness program, or weight loss plan based solely on the calculations provided by our tools.
If you think you may have a medical emergency, call your doctor or your local emergency services immediately.

3. Limitations of the Tools

Please be aware of the inherent limitations of mathematical health formulas:

Body Mass Index (BMI) does not differentiate between fat mass and muscle mass. It may overestimate body fat in athletes or muscular individuals, and underestimate body fat in older persons or those who have lost muscle mass.
Calorie and BMR Calculators provide estimates based on population averages. Your actual metabolic rate can vary significantly based on genetics, hormonal factors, past dieting history, and medical conditions (such as thyroid disorders).

4. No Doctor-Patient Relationship

Use of this website, including submitting any inquiries via our contact forms or email, does not create a doctor-patient, therapist-patient, or other healthcare professional relationship between you and FastBMI or any of its contributors.

5. Accuracy of Information

While we strive to keep our formulas up-to-date and based on current scientific literature (such as guidelines from the WHO or CDC), medical knowledge evolves rapidly. We make no representations or warranties of any kind, express or implied, about the completeness, accuracy, reliability, suitability, or availability of the website's information, products, services, or related graphics.
