Understanding Body Fat and Ideal Weight

Body Fat Percentage is estimated using the U.S. Navy method, based on height, neck, and waist measurements. It reflects your current fat mass relative to total weight.

Ideal Body Weight is calculated using your lean body mass (adjusted for 10% muscle loss) and your target body fat percentage.

Healthy Guidelines

  • Men: Essential fat is ~2-5%; healthy range is 6-24%.
  • Women: Essential fat is ~10-13%; healthy range is 14-31%.
  • Warning: Targets below essential levels (2% for men, 10% for women) may pose health risks.

Consult a professional before pursuing extreme body fat goals.
