About Our Health Tools
Our health tools use standard, evidence-based formulas — WHO BMI thresholds, the Mifflin-St Jeor equation, the U.S. Navy body fat method, and the 90-minute sleep cycle model — to give you fast, useful health estimates. These tools are a helpful starting point, not a substitute for advice from a doctor or registered dietitian.
