Obesity and physical fitness are closely related, influencing each other in significant ways. Individuals with higher body fat often experience decreased fitness levels due to reduced cardiovascular endurance, strength, and flexibility. Conversely, regular exercise promotes weight loss and improves overall body composition, reducing the risk of associated health issues. High levels of body fat can lead to conditions such as diabetes and heart disease, further impairing fitness. Therefore, improving physical fitness through exercise and proper diet can reduce obesity levels, create a healthier lifestyle, and enhance longevity. Addressing both fitness and obesity is crucial for overall health.
