The definition provided is not accurate. Obesity is generally defined as an excessive accumulation of body fat that presents a risk to health. It's often assessed using the Body Mass Index (BMI), which is a calculation based on an individual's weight and height. The standard BMI categories are as follows:
- Underweight: BMI less than 18.5
- Normal weight: BMI 18.5 to 24.9
- Overweight: BMI 25 to 29.9
- Obesity: BMI 30 or greater
Obesity can lead to various health issues, including heart disease, diabetes, and certain types of cancer. It is important to consider factors such as age, sex, and muscle mass when assessing body weight and health risks.
