Final answer:
Overweight is defined as having a BMI range of 25 to 29.9 kg/m², which is different from obesity, which is defined as a BMI of over 30 kg/m².
Step-by-step explanation:
Overweight is defined as a Body Mass Index (BMI) of 25 to 29.9 kg/m². To be categorized as overweight, a person's weight in relation to their height falls into this BMI range. A BMI below 18.5 is generally considered underweight, 18 to 24.9 is normal weight, over 25 is overweight, and over 30 is obese. It is important to note that the BMI has limitations and may not accurately represent an individual's body fat percentage or overall health, particularly in individuals with high muscle mass like athletes.
