OBESITY• Increasing in the U.S. and throughout the world, including third world countries• About 12 million Americans are thought to be morbidly obese (BMI > 40)•Physicians now consider it the country’s leading health problem

•Affects 1/3 of adults in the U.S.•Nearly half of adults in the U.S. have a BMI > 25•Disproportionately affects minorities from the African-American, Native American and Hispanic populations

•Also highly publicized•Not included in the psychiatric diagnostic nomenclature•Considered not especially alarming, evoking more a sense of disgust directed to some degree at the behavior but to a larger extent at the resultant body

Very few instances where it is possible to overcome negative stereotyping and social stigma

Increase in Obesity among children and associated increase in serious health problems including diabetes and NAFLD is considered alarming from a public health perspective

•Increase in obesity at all ages and life stages is associated with morbidity and disability•Enormous cost to society in lost work productivity, disability and medical costs

• Imbalance between energy consumption (calories) and energy expenditure

• Resultant abnormal body weight (BMI < 19 or BMI > 25• Persons in these categories may be otherwise healthy• Persons in these categories may be genetically programmed to

maintain weights in these ranges without abnormal food consumption or energy expenditure

• Body weight tends to reach and fluctuate around a “set point” or “settling point”

• Persons in the normal weight range may eat in a manner that increases disease and mortality risk or that has resulted in morbidity
