  3. 3. FACTS <ul><li>becoming an increasingly common topic </li></ul><ul><li>multiplied by 100% in the past 20 years </li></ul><ul><li>2/3’s of Americans </li></ul><ul><li>400,000 deaths per year </li></ul><ul><li>1 in 4 children are overweight and at risk </li></ul><ul><li>effects all races, genders, income levels, and age groups </li></ul><ul><li>U.S. highest % of obesity </li></ul>
  4. 4. <ul><li>The graph shows the % of total country populations of people with a BMI of over 30 </li></ul>http://en.wikipedia.org/wiki/Image:Bmi30chart.png
  5. 5. HEALTH CONCERNS <ul><li>#1 chronic illness in America </li></ul><ul><li>in most cases it’s completely preventable </li></ul><ul><li>increasing at the rate of an infectious disease </li></ul><ul><li>9% of all medical spending goes to treat obesity related issues </li></ul><ul><li>25% are completely sedentary (non moving) </li></ul>

  7. 7. GENETICS <ul><li>Genes controlling appetite and metabolism effect chances </li></ul><ul><li>Studies with identical twins have shown 77% childhood obesity is inherited </li></ul><ul><li>FTO gene study concluded that heterozygous 30% and homozygous 70% chances of increased risk of obesity </li></ul><ul><li>More genes being discovered that increase obesity chances </li></ul><ul><li>“ thrifty genotype hypothesis” </li></ul><ul><li>-same genes that helped our ancestors survive famines are challenged by food being plentiful year round. </li></ul>
  8. 8. <ul><li>50 chromosomal locations are relevant to obesity </li></ul><ul><li>Genetic factors play a role but to fully develop a lot of caloric intake must occur </li></ul>http://en.wikipedia.org/wiki/Obesity
