Prevent Obesity 

Obesity is a serious disease with serious consequences. Evan wants to prevent obesity in our community and offers nutrition counseling services, wellness programs and fitness classes.

What is Obesity?

Obesity is a serious disease with symptoms that build slowly over an extended period of time. The National Institutes of Health (NIH) define morbid obesity as:

  • Being 100 pounds or more above your ideal body weight
  • Or, having a Body Mass Index (BMI) of 40 or greater
  • Or, having a BMI of 35 or greater and one or more co-morbid conditions

Morbid obesity interferes with basic physical functions such as breathing or walking.

Long-term implications include shorter life expectancy, serious health consequences in the form of weight-related conditions and a lower quality of life with fewer economic and social opportunities.

Obesity is a serious public health issue. In the U.S.:

  • 24 million U.S. adults are living with morbid obesity and may qualify for bariatric surgery based on NIH guidelines.
  • By 2010, it is projected that there may be 31 million U.S. adults living with morbid obesity and may qualify for bariatric surgery based on NIH guidelines.

Health Risks of Obesity

Health risks by condition.

Men living with morbid obesity have 50% to 100% higher mortality rates than men with a healthy weight1.

Men with Morbid Obesity Have Higher Cancer Mortality Rates*

Type of Cancer  Men 
All Types 52% higher3 

Women living with morbid obesity have 50% to 100% higher mortality rates than women with a healthy weight1.

Women with Morbid Obesity Have Higher Cancer Mortality Rates*

Types of Cancer  Women
 All types 62% higher3

* Compared to people with a healthy weight.

* A Note on Relative Risk

The chart refers to “relative risk,” which compares how likely an event is to occur to a person versus another person. The chart shows how much more likely a person with morbid obesity is to develop cancer or die from cancer versus a person with a healthy weight.
