Answer 1

A) Body composition is a method of describing what the body is made of. It includes fat, protein, minerals and body fluids. It also explains weight more accurately than BMI.

C) BMI or Body Mass Index is a method of estimating a person's body fat levels based on a person's weight and height measurement.

There are some limitations based on an individual's gender, age, and athletic ability. These limitations include the following:

• Women might have more body fat than men.
• Elder people may have more body fat than younger adults.
• Highly trained athletes often have a high BMI due to higher levels of muscle mass which increases their body weight measurement, rather than higher body fat causing a higher weight measurement.

D) Visceral fat is a type of body fat that's stored within the abdominal cavity. It's located near several vital organs, including the stomach, liver, and intestines.

E) Anorexia nervosa, is a potentially life-threatening eating disorder that is characterized by self-starvation and excessive weight loss. The disorder is diagnosed when a person weighs at least 15% less than his or her normal/ideal body weight. Extreme weight loss in people with anorexia nervosa can lead to dangerous health problems and even death.

F) Bulimia Nervosa is a psychological and severe life-threatening eating disorder described by the ingestion of an abnormally large amount of food in short period of time, followed by an attempt to avoid gaining weight by purging what was consumed.
