Body fat percentage is the proportion of your total body weight that consists of fat tissue. It's a key indicator of fitness and health, separate from overall weight.

Healthy body fat ranges vary by gender. For men: 6-24% (athletes 6-13%, fitness 14-17%, average 18-24%). For women: 14-31% (athletes 14-20%, fitness 21-24%, average 25-31%).

Body fat calculators provide estimates. Skinfold measurements are more accurate than BMI-based methods, but professional methods like DEXA scans are the most precise.

The 7-site skinfold method measures fat thickness at seven body locations: chest, abdominal, thigh, tricep, subscapular, suprailiac, and midaxillary. It's one of the most accurate field methods.

Measure body fat every 2-4 weeks to track progress. Daily measurements aren't recommended as body fat changes slowly and daily fluctuations can be misleading.

Yes, having too little body fat (below 6% for men, 14% for women) can cause health issues including hormonal imbalances, decreased immune function, and organ problems.

BMI only considers height and weight, while body fat percentage measures actual fat tissue. Athletes may have high BMI but low body fat, while some people have normal BMI but high body fat.

Body fat percentage is affected by diet, exercise, age, genetics, hormones, and lifestyle factors. Regular exercise and proper nutrition are key to maintaining healthy levels.

Body fat percentage is one component of body composition, which also includes muscle mass, bone density, and water content. Body composition gives a more complete picture of health.

To reduce body fat: combine regular cardio and strength training, maintain a caloric deficit through diet, get adequate sleep, manage stress, and be consistent with your routine.
