Obesity is caused by a combination of factors including poor diet, lack of physical activity, genetics, and certain medical conditions.

BMI, or Body Mass Index, is a measure that uses height and weight to estimate body fat. It’s used to classify individuals into different weight categories, such as underweight, normal weight, overweight, and obese. A BMI of 30 or higher is considered obese.

It’s often used along with other measurements to get a full picture of health.
