Defined as abnormal or excessive fat accumulation that
presents a risk to health.
A crude population measure of obesity is the body mass
index (BMI), a person’s weight (in kilograms) divided by
the square of his or her height (in meters).
 A person with a BMI of 30 or more is generally
considered obese.
 A person with a BMI equal to or more than 25 is
considered overweight.

 An energy imbalance between calories consumed and
calories expended.
 Globally, there has been:
 an increased intake of energy-dense foods that
are high in fat
 an increase in physical inactivity due to the
increasingly sedentary nature of many forms of work,
changing modes of transportation, and increasing
urbanization.
 Changes in dietary and physical activity patterns
are often the result of environmental and societal
changes associated with development
