Frequently Asked Questions
🤔 How accurate are these body fat calculations?
These methods provide estimates with 3-6% accuracy. The Navy method is generally most accurate, while BMI-based estimates are less precise. For exact measurements, use DEXA scans or hydrostatic weighing.
⚖️ What”s a healthy body fat percentage?
For men: 14-17% is fitness level, 18-24% is average. For women: 21-24% is fitness level, 25-31% is average. Athletes typically have lower percentages, but too low can be unhealthy.
📊 How does body fat differ from BMI?
BMI uses only height and weight, while body fat percentage accounts for body composition. Athletes may have high BMI but low body fat due to muscle mass.
🏃♂️ How can I reduce body fat percentage?
Combine cardiovascular exercise with strength training, maintain a moderate caloric deficit, eat adequate protein, and be consistent. Focus on sustainable lifestyle changes rather than extreme measures.
⏰ How often should I measure body fat?
Monthly measurements are sufficient for tracking progress. Body fat changes slowly, and daily fluctuations are normal due to hydration, food intake, and other factors.
