It is typically measured using the Body Mass Index (BMI) scale, with a BMI of 30 or higher indicating obesity. Obesity is associated with various health risks, including heart disease, diabetes, and certain types of cancer. Lifestyle factors such as overeating, sedentary behavior, and lack of physical activity contribute to its prevalence.
