Obesity A Scientific Update

  1. 1. Obesity: A Scientific Update<br />Presented by: Holly Shaffer, MS CHES<br />February 2009<br />
  2. 2. Obesity A national Trend- How Bad is It?<br />60% of Americans are overweight or obese.<br />The risk of becoming obese if you are 30 years old today is 39% for women and 48% for men.<br />Studies predict that based on current obesity rates, especially among youth and minorities, life expectancy in the US can be expected to decline!<br />Fido and Fi Fi are not immune either. Our pets are are suffering the same ill effects of being overweight<br /> that we are.<br />
  3. 3. Obesity Trends* Among U.S. AdultsBRFSS, 1986<br />(*BMI ≥30, or ~ 30 lbs. overweight for 5’ 4” person)<br />No Data <10% 10%–14%<br />
  4. 4. Obesity Trends* Among U.S. AdultsBRFSS, 1995<br />(*BMI ≥30, or ~ 30 lbs. overweight for 5’ 4” person)<br />No Data <10% 10%–14% 15%–19% <br />
  5. 5. Obesity Trends* Among U.S. AdultsBRFSS, 2000<br />(*BMI ≥30, or ~ 30 lbs. overweight for 5’ 4” person)<br />No Data <10% 10%–14% 15%–19% ≥20%<br />
  6. 6. Obesity Trends* Among U.S. AdultsBRFSS, 2005<br />(*BMI ≥30, or ~ 30 lbs. overweight for 5’ 4” person)<br /> No Data <10% 10%–14% 15%–19% 20%–24% 25%–29% ≥30%<br />
  7. 7. Obesity Trends* Among U.S. AdultsBRFSS, 2007<br />(*BMI ≥30, or ~ 30 lbs. overweight for 5’ 4” person)<br /> No Data <10% 10%–14% 15%–19% 20%–24% 25%–29% ≥30%<br />
  8. 8. Extra Pounds and health Care Spending<br />Obesity related illness have been responsible for a tenfold increase in private health insurance spending since 1987.<br />Taking the frequency of obesity into account for a company with 1,000 employees obesity would cost about $285,000 a year (For Bentley that would be close to $900,000 a year!)<br />It is estimated that treating an obese individual costs 1,244 more than treating a healthy –weight individual. In 1987, the cost difference was $272.<br />Source: RTI International Health, Social, and Economics Research and the CDC, 2005<br />
  9. 9. Not all Fat is created Equal<br />Apple vs. Pear- Which is better? Why?<br />Visceral Fat (fat around the middle)<br /> Held within the deep organs increases pro-inflammatory diseases like:<br />CAD (Coronary Artery Disease)<br />Depression/Bipolar<br />Alzheimer's<br />RA<br />Hip to Waist Ratio<br />Greater than 35 inches for a woman<br /> <.80 low risk <.85 Moderate risk<br />Greater than 40 inches for a man<br /> <.90 low risk <1.0 moderate risk<br />Waist to hip ratio is more important than BMI or body fat measure when it comes to estimating risk of heart disease due to obesity!<br />
  10. 10. How Body Shape Influences Your Health<br />Pears<br />Apples<br />Health Challenges: Heart disease, diabetes, breast cancer<br />Diet strategy – High in complex carbohydrates, moderate in fats, moderate in protein<br />Best exercise- Walk 30 minutes every day to burn apple-zone fat<br />Health Challenges: Osteoporosis, varicose veins<br />Diet strategy – Low in fat, high in complex carbohydrates, moderate in protein<br />Best exercise- Resistance training 3 times a week to build bones<br />Source: The Body Shape Solution to Weight Loss and Wellness: 2005<br />
  11. 11. Food Addiction: Real or Imagined?<br />Is it possible to be addicted to food?<br />YES!<br />The right cortex of the brain controls pleasure and motivation. <br />Both cocaine and food cravings are linked with this cortex showing a common brain pathway for drug addiction, food cravings and hunger.<br />Our brains can actually get “high” on highly-preferred foods usually high-sugar and high fat. <br />Chocolate the Perfect Fix!<br />*However drugs are far more powerfully addictive than food!<br />
  12. 12. Factors that affect Our Desire to eat certain Foods<br />Genes/jeans- obese parents = obese kids<br />Food preferences (habits formed early in life usually by age 2)<br />Learned eating patterns<br />Social family influence<br />Environmental cues<br />Personality/Mood<br />
  13. 13. How to Curb food Addictions<br />Wait 15 minutes before you “give in” to your craving get busy and do something (walk, drink water, start a household chore, etc.)<br />Find a food with characteristics you crave but less fat and sugar.<br />Plan a controlled mini-binge; portion control is key- Remember the 3 Bite Rule.<br />
  14. 14. Sleep Cycle linked to Overweight<br />Studies show strong connection with lack of good quality sleep and weight gain.<br />People who are sleep deprived have increased appetites and crave foods that are high in calories, fat and sugar.<br />Over the past 40 years the amount of sleep Americans average each night has dropped by two hours from 8.5 to less than 7 hours per night.<br />People who get less than 8 hours of sleep are 15% hungrier and are 15% more likely to over eat.<br />
  15. 15. Breakfast- The Most Important Meal of the Day<br />Approximately 20% of all US adults and 27% of young American women skip breakfast.<br />Those who eat cereal/grains for breakfast have lower BMI’s than breakfast skippers or meat and egg eaters.<br />Studies show that people who successfully lose weight and keep it off long term are routine breakfast eaters.<br />
  16. 16. The French Connection<br />Only 7 % of French adults are obese<br /> compared to 22% of Americans.<br />The French consume more dietary fat, but fewer calories overall<br />Portion sizes are considerably smaller. Restaurants in Philadelphia served meals that averaged 72% more food than those served in Parisian counterparts.<br />Red Wine, in moderation, is also key.<br />
  17. 17. Omega 3’s- Essential to our Diet <br />Why Omega 3’s?<br />At the cellular level makes all cell membranes more fluid and enables it to heal itself against free radicals<br />Protects against various disease states including:<br />Alzheimer's<br />CAD<br />Depression/Bipolar/Schizophrenia <br />RA<br />Osteoarthritis<br />Allergy and asthma<br />Helps brain development in babies and children<br />Improves skin clarity and tone<br />How Much? 1,000-4,000 mg per day. <br />Bottom Line- EVERONE should make sure they get enough Omega 3<br />Bonus Question- Name a good food source of Omega 3’s?<br />
  18. 18. Vitamin D- Good for More Than Strong Bones and Teeth<br />Many emerging studies are pointing to Vitamin D’s ability to affect the genes and their receptors.<br />61% of adults and kids are deficient.<br />Low levels of Vit. D have been linked to and can cause:<br />MS, Parkinson’s, Type I and II diabetes, breast cancer, fibromyalgia, depression, and increased pain in the elderly<br />Recommended we get 400 iu/day. In order to get the 100% daily dose we need two things.<br />Food/sun exposure<br />Supplments<br />Can have a simple blood test to measure the inactive form in our bodies – 125 hydroxy D3<br />
  19. 19. New Sciences are Emerging<br />Epigentics- Exposure to nutrients in utero has long-term and substantial impact on our health later on in life.<br />Nutragenomics-the nutrients we consume have positive and negative affects on our genes (turn them on or off, bind receptors or helps to free receptors).<br />
