      • 40+ is morbidly obese
      • BMI measures body weight
      • and height.
      • when more calories are
      • consumed than burned
      • 20%+ over the healthy weight
      http://en.wikipedia.org/wiki/Obesity
    • FACTS
      • becoming an increasingly common topic
      • multiplied by 100% in the past 20 years
      • 2/3’s of Americans
      • 400,000 deaths per year
      • 1 in 4 children are overweight and at risk
      • effects all races, genders, income levels, and age groups
      • U.S. highest % of obesity
      • The graph shows the % of total country populations of people with a BMI of over 30

    • HEALTH CONCERNS
      • #1 chronic illness in America
      • in most cases it’s completely preventable
      • increasing at the rate of an infectious disease
      • 9% of all medical spending goes to treat obesity related issues

      • -coronary heart disease
      • -stroke
      • -congestive heart failure
      • - and more
    • GENETICS
      • Genes controlling appetite and metabolism effect chances
      • Studies with identical twins have shown 77% childhood obesity is inherited
      • FTO gene study concluded that heterozygous 30% and homozygous 70% chances of increased risk of obesity
      • More genes being discovered that increase obesity chances
      • “ thrifty genotype hypothesis”
      • -same genes that helped our ancestors survive famines are challenged by food being plentiful year round.
      • 50 chromosomal locations are relevant to obesity
      • Genetic factors play a role but to fully develop a lot of caloric intake must occur
      http://en.wikipedia.org/wiki/Obesity
    • ENVIRONMENTAL FACTORS
      • Average caloric intake has increased(1991-1996 1774 kc -2002 kc)
      • -readily available foods- fast food and junk food
      • -buying food in bulk
      • -healthier foods more expensive than fast food

      • -increase activity level
      • For obese individuals: (all the above)
      • -prescription medication to absorb fat and control hunger
      • -weight loss surgery (gastric bypass)
    • The most effective way to treat obesity is to live a healthy lifestyle. 
    • OVERVIEW
      • Obesity is growing concern
      • Both genetic and environmental factors cause it
      • Weight loss surgery is sometimes the only treatment
      • All negative health effects
