Body fat percentage significantly relates to health and fitness levels as it provides a more accurate picture of body composition than body mass index (BMI). A healthy body fat percentage indicates an appropriate balance between fat and lean mass, affecting metabolism, endurance, and overall functionality. Excess body fat, particularly visceral fat, is linked to various health conditions, including heart disease, diabetes, and hypertension. Conversely, too low body fat can impair hormonal balance and immune function. Understanding and monitoring body fat percentage can help individuals make informed decisions about their fitness and nutritional goals, enhancing overall health outcomes.
