Frequently Asked Questions
What is a healthy body fat percentage?
Healthy body fat ranges vary by gender and age. Generally, men should aim for 10-20% and women for 16-25%, but optimal ranges depend on individual factors.
How accurate are body fat calculators?
Online calculators provide estimates with accuracy varying by method. BMI-based calculations are less accurate than circumference-based methods. Professional testing is most accurate.
Can I reduce body fat percentage?
Yes, through a combination of proper nutrition, regular exercise, strength training, and maintaining a calorie deficit. Focus on sustainable lifestyle changes.
What's the difference between weight loss and fat loss?
Weight loss includes water, muscle, and fat. Fat loss specifically targets adipose tissue. Strength training helps preserve muscle during weight loss.
