Obesity is a medical condition where excess body fat has accumulated over time, increasing health risks. It can be measured by body mass index. Obesity is linked to increased rates of diseases like diabetes and high blood pressure. It may be caused by lack of physical activity, excessive calorie intake, genetics, or medications. Management involves a healthy diet and exercise through aerobic activity, stretching, or strength training. Maintaining a balanced diet with foods from major food groups and limiting fats/sugars promotes overall well-being.
