Body Fat Percentage: Healthy Ranges & How to Measure
Why Body Fat Percentage Matters
Body fat percentage tells you what proportion of your body weight is fat versus lean tissue (muscle, bone, organs, water). Unlike BMI, it accounts for body composition and gives a more accurate picture of health and fitness.
Healthy Ranges
Men: Essential fat 2-5%, athletes 6-13%, fitness 14-17%, acceptable 18-24%, obese 25%+
Women: Essential fat 10-13%, athletes 14-20%, fitness 21-24%, acceptable 25-31%, obese 32%+
Women naturally carry more body fat due to reproductive functions and hormonal differences.
Measurement Methods
Skinfold callipers: Affordable and reasonably accurate when done by a trained professional. Measures skin thickness at specific body sites.
Bioelectrical impedance (BIA): Found in smart scales. Convenient but accuracy varies with hydration levels. Best used for tracking trends over time.
DEXA scan: The gold standard. Uses X-ray technology to precisely measure fat, muscle, and bone. Available at some clinics for around £100-200.
Navy method: Uses neck and waist measurements (plus hip for women). Free, quick, and surprisingly accurate for most people.
Reducing Body Fat
The most effective approach combines a moderate calorie deficit with strength training and adequate protein intake (1.6-2.2g per kg of body weight). Aim to lose 0.5-1% body fat per month for sustainable results. Rapid fat loss often means losing muscle too, which hurts your metabolism long-term.
