Understanding Body Fat Percentage
What is Body Fat Percentage?
Body fat percentage is the proportion of fat in your body compared to your total body weight. It is an important indicator of fitness and health.
How is Body Fat Percentage Calculated?
The U.S. Navy Method uses measurements of height, neck, waist, and hips (for females) to estimate body fat percentage. This method is widely used for its accuracy and simplicity.
Limitations of Body Fat Calculations
While the U.S. Navy Method provides a good estimate, it may not account for all individual differences in body composition. It should be used alongside other assessments for a comprehensive health evaluation.
Remember: Always consult with a healthcare professional for personalized health advice and before making significant changes to your diet or exercise routine.
