Final answer:
Overweight is defined as having a BMI between 25 and 29.9, with obesity being a BMI of 30 or higher.
Step-by-step explanation:
Overweight is a condition that is less serious than obesity and is defined by having a body mass index (BMI) between 25 and 29.9. A BMI of 30 or higher is considered obese. It's important to note that while BMI is a helpful tool for assessing population health, it may not perfectly represent an individual's health status due to not accounting for muscle mass and other factors. Nevertheless, understanding one's BMI can be a starting point for addressing weight-related health issues.
