Tool Limitations

The calculators and tools on this site use standard formulas (BMI, Navy body fat, Harris-Benedict, Mifflin-St Jeor, etc.) that are widely used in research and clinical settings. However:

  • These are estimates, not precise measurements.
  • Individual results may vary based on genetics, body composition, medical conditions, medications, and other factors not captured by these formulas.
  • BMI in particular is a population-level screening tool with known limitations for individuals (athletes, older adults, certain ethnic groups).
  • Body fat estimation methods (like the Navy tape method) have margins of error of approximately ±3%.
  • Calorie needs calculators provide rough estimates; actual metabolic rates vary significantly between individuals.
