What we use as evidence
Our calculator and articles explain TDEE, BMR, activity multipliers, calorie goals, and macronutrients. The site identifies the Mifflin-St Jeor equation as its default BMR method. A formula-based result is a starting estimate, not a direct measurement of an individual’s calorie needs.
When checking a health or formula claim, we aim to use the original research or guidance issued by a relevant public-health, clinical, or research organization where available. We prefer a direct source over a summary of that source. We should identify the source clearly and link to it in the relevant article when a claim needs support.
How we handle uncertainty
We check whether a source supports the specific statement being made, including who it studied and what it measured. We avoid turning a general finding into a promise about one person. We also explain limitations that matter to readers, such as the uncertainty in selecting an activity level and the need to adjust a starting estimate using real-world progress.
Some existing articles may not yet show direct references for every substantive claim. This page sets a standard for reviewing and improving those articles; it does not claim that every older page already meets it.
