Body fat percentage is a crucial health indicator that reflects the ratio of fat mass to total body mass. It can be used to assess an individual’s health, fitness level, and risk for chronic diseases such as obesity, diabetes, and heart disease.
Historically, body fat percentage was measured using underwater weighing or body densitometry, which involved submerging a person in water or using sophisticated equipment to measure their density. However, these methods are often expensive, inconvenient, and not widely accessible.
