Determining body fat loss entails quantifying the reduction in adipose tissue mass. For example, if an individual weighing 80 kilograms loses 2 kilograms of fat, they have achieved a 2.5% reduction in body fat.
Tracking body fat loss is crucial for maintaining a healthy weight and composition. It enables individuals to assess progress, adjust nutritional plans, and optimize exercise regimens. Historically, the body mass index (BMI) has been used to estimate body fat, but more accurate techniques have emerged.
