General Information Disclaimer
The information on FitMetrics (quickbmi.in) is for general educational purposes. I've put effort into making the formulas accurate and the content honest, but I can't guarantee that every result is right for every person — human bodies are more variable than any formula can capture.
Any reliance you place on information from this website is at your own risk. FitMetrics accepts no responsibility for loss or damage arising from your use of it.
Health and Medical Disclaimer
The calculators, fitness tools, and articles on FitMetrics are not a substitute for professional medical advice, diagnosis, or treatment. None of this content has been reviewed by a doctor and it shouldn't be used as medical guidance.
Talk to your doctor, dietitian, or a qualified healthcare professional before making decisions about:
- Body weight, BMI, or body composition
- Calorie and macronutrient requirements
- Exercise intensity, heart rate targets, or fitness assessment
- Hydration and nutritional needs
- Any medical condition, medication, or treatment
- Weight management for any purpose
Never disregard professional medical advice or delay seeking it because of something you have read on this website.
Calculator Accuracy and Limitations
All calculators use established formulas — Mifflin-St Jeor for BMR/TDEE, Devine for ideal weight, Karvonen for heart rate zones, the US Navy circumference method for body fat, and so on. But:
- All results are estimates, not precise measurements
- Formula accuracy varies between individuals based on genetics, body composition, ethnicity, age, and health status
- BMI does not account for muscle mass, bone density, or fat distribution
- Calorie estimates carry a typical margin of error of ±10–15%
- Body fat estimates from circumference measurements carry a typical margin of error of ±3–5%
For clinical-grade assessments, consult a healthcare professional who can perform appropriate diagnostic testing.
Fitness and Exercise Disclaimer
Before starting a new exercise programme — especially if you have any pre-existing conditions, cardiovascular risk factors, joint issues, or have been sedentary for a long time — check with your doctor first. Heart rate zones, VO2 max estimates, and fitness assessments here are reference points, not clinical evaluations.
Nutritional Disclaimer
Calorie, macro, protein, and hydration targets are starting-point estimates based on population averages. They don't account for conditions like diabetes, kidney disease, eating disorders, or any situation requiring a specialised therapeutic diet. If any of those apply to you, please work with a registered dietitian who can tailor guidance to your actual circumstances.
Pregnancy Disclaimer
The pregnancy calculators here are general reference tools only. Every pregnancy decision should be made with your midwife, obstetrician, or healthcare provider — not a website calculator.
