The relationship between body composition and health is significant, as it refers to the proportion of fat, muscle, bone, and water in the body. A healthy body composition, characterized by a lower percentage of body fat and higher lean muscle mass, is linked to a reduced risk of chronic diseases such as obesity, diabetes, and heart disease. Monitoring and improving body composition through diet and exercise can lead to better metabolic health, increased physical performance, and enhanced overall quality of life, highlighting the importance of maintaining a healthy body composition for lifelong wellness.
