What is Obesity?

Obesity results from a complex interaction of genetic, behavioral and environmental factors causing an imbalance between energy intake and energy expenditure.

According to the National Institutes of Health, an increase in body weight of 20% or more above desirable weight is the point at which excess weight becomes an established health hazard. Lower levels of excess weight can also constitute a health risk, particularly in the presence of other disorders like diabetes, hypertension and heart disease.
