Health numbers deserve care, so every page on Fitness BMI Calculator follows the same process.
1. Start from a published method
Each calculator uses a formula from medical or sports science literature: BMI with WHO and Indian adult cut-offs, the Mifflin St Jeor equation for resting energy, the US Navy tape method for body fat, the Devine, Robinson, Miller and Hamwi ideal body weight formulas, MET values from the Compendium of Physical Activities, the Karvonen method for heart rate, and WHO growth standards for children. The sources used are listed at the foot of each page.
2. Calculate, never copy
Every number in our tables is produced by a script from the formula, not typed by hand or copied from another website. The calculators on the page use the same formulas, so the table and the tool always agree.
3. Write for one question
Each page answers one search question in its first lines, then explains what changes the number, gives worked examples and says when to see a professional. We write in plain Indian English with kg, cm and familiar foods.
4. Drafting and review
Page drafts are prepared with the help of AI writing tools, working from the formulas and sources above. Every draft is then checked: numbers are recalculated by script, wording is checked against our style rules, and claims are compared with the named sources. Pages that cannot be backed by a source are cut.
5. Keep it current
When guidance changes, for example new Indian obesity criteria or updated nutrient requirements, we update the formulas and the pages together. Spotted something out of date? Please tell us.
