Obesity is a medical condition characterized by excessive body fat that can negatively impact health. It is often measured using the Body Mass Index (BMI), which compares a person's weight to their height. When a person's BMI is 30 or higher, they are considered obese. This condition can lead to various health issues, including heart disease, diabetes, and joint problems. Several factors contribute to obesity, including poor diet, lack of physical activity, and genetics. Many people consume high-calorie foods and sugary drinks, which can lead to weight gain. Additionally, a sedentary lifestyle, often influenced by technology and screen time, can make it harder to maintain a healthy weight.
