Answer:
1) A person is obese if he or she has an excess amount of body fat.
Explanation:
Obesity is a medical condition in which a person accumulates too much body fat, which will have a negative impact on his or her health. To determine if a person is obese, we calculate their body mass index, which is the guide to diagnoses this condition.
It's important to distinguish body mass with muscular mass. Mass refers generally to fat or muscle, all together. A large amount of muscle mass not necessarily define obesity, because you can have bodybuilders athletes who have large amount of muscle mass but they aren't obese.
