1General Information
SnapBodyCalc provides online health and fitness calculators for informational and educational purposes only. While we aim to use scientifically recognized formulas and provide accurate calculations, we make no guarantees regarding the completeness, accuracy, or reliability of the results.
All calculations are estimates and should be interpreted accordingly.
2No Medical Advice
SnapBodyCalc does not provide medical, health, nutritional, or fitness advice.
The information and results generated by our calculators:
- Do not constitute medical advice
- Are not a substitute for professional healthcare guidance
- Should not be used for diagnosing or treating medical conditions
- Should not replace consultation with a qualified physician or healthcare professional
Always seek professional advice before making health-related decisions.
3Accuracy of Results
Although our calculators are based on widely accepted formulas (such as Mifflin-St Jeor and the US Navy method), we cannot guarantee:
- Perfect accuracy for every individual
- Applicability to all body types, ages, or medical conditions
- Correct interpretation of results without professional context
You are solely responsible for how you use the information provided.
4Calculator-Specific Limitations
Each tool has known limits. In particular:
- BMI: a screening ratio of weight to height only. It cannot distinguish fat from muscle or bone, and category boundaries (for example 25.0) are conventions, not thresholds where health changes.
- Body fat: estimated with the US Navy circumference method and classified using American Council on Exercise categories. Tape measurements are error-prone, and the equation is least reliable for athletes, very lean people and people with obesity.
- Lean body mass: the headline figure uses the Boer (1984) equation; Hume (1966) is shown only as a cross-check. Neither measures body composition directly — only DEXA or hydrostatic weighing does.
- TDEE, calories and macros: based on Mifflin-St Jeor plus activity multipliers. Real energy expenditure varies by 10–20% between individuals with identical inputs.
- Calories burned: MET-based estimates from published compendium values, not measured output. Wearables and gym machines will disagree.
- Water intake: built on a 33 ml per kilogram rule of thumb, which is a practical heuristic rather than a clinical guideline. People with kidney disease, heart failure or fluid restrictions must follow medical advice instead.
- Protein: the RDA of 0.8 g/kg is a deficiency-prevention minimum; higher targets come from sports-nutrition position stands and apply to people who train.
- Body age: an in-house lifestyle index that expresses BMI and activity as an adjustment to your chronological age. There is no published equation behind it, it has not been validated against any ageing clock, and it is not a biological-age or clinical measurement.
- Ideal weight: classic height-based formulas (Devine, Hamwi, Robinson, Miller) developed for drug dosing, not as personal targets.
All calculators assume healthy, non-pregnant adults unless stated otherwise, and none of them are suitable for children, for pregnancy or breastfeeding decisions, or for managing a diagnosed condition.
5Limitation of Liability
To the maximum extent permitted by law, SnapBodyCalc, its owners, and operators shall not be liable for any direct or indirect damages arising from:
- Use or misuse of the service

- Health decisions made based on provided estimates

- Loss of saved history (calculation history is stored only in your own browser and is lost if you clear site data)
6No Warranties
The service is provided on an "as is" and "as available" basis without warranties of any kind, whether express or implied, including but not limited to:
- Fitness for a particular purpose
- Accuracy or completeness of results
- Uninterrupted or error-free operation
