What is Obesity?
Obesity is a condition where a person has an excessive amount of body fat, leading to a weight that is higher than what is generally considered healthy for their age, sex, and background. It is often measured using the Body Mass Index (BMI), with a BMI over 30 typically defined as obese. This condition can affect overall health and varies depending on individual factors.
