Frequently Asked Questions
How accurate is the Navy body fat formula?
The US Navy method is considered reasonably accurate (within 3-4% of DEXA scans) and is widely used by the military and fitness professionals. It's more accurate than BMI for estimating body composition. The most accurate methods are DEXA scans and hydrostatic weighing, but these require special equipment.
What is a healthy body fat percentage?
For men: Essential fat 2-5%, Athletes 6-13%, Fitness 14-17%, Average 18-24%, Obese 25%+. For women: Essential fat 10-13%, Athletes 14-20%, Fitness 21-24%, Average 25-31%, Obese 32%+. Women naturally carry more essential fat than men.
How do I measure my waist and neck correctly?
Waist: Measure at the narrowest point (usually around your navel), keep the tape horizontal and snug but not compressing skin. Neck: Measure just below the larynx (Adam's apple), keep chin parallel to the ground. For women, also measure your hips at the widest point.
Can I reduce body fat in a specific area?
No - 'spot reduction' is a myth. When you lose fat, it comes from all over your body based on genetics. You can't target belly fat specifically, but overall fat loss through caloric deficit and exercise will reduce fat everywhere, including stubborn areas.
How quickly can I reduce body fat?
A safe and sustainable rate is 0.5-1% body fat per month, or about 1-2 lbs of fat per week. Faster loss often means losing muscle too. Consistent caloric deficit (500-1000 calories/day below maintenance) combined with strength training is most effective.
