This article explains what constitutes a healthy body fat percentage, how it varies by age, sex, and fitness level, and why it matters beyond aesthetics. It breaks down body fat categories for both men and women (e.g., essential fat, athletic, fitness, acceptable, overweight ranges) and reviews measurement methods such as skinfold calipers, bioelectrical impedance, and DEXA scans. The piece also challenges the stigma around body fat, promoting a positive, holistic dialogue around health rather than appearance. It emphasises that both too little and too much body fat are harmful and encourages readers to find a balance that supports long-term wellbeing.
