  4. BMI Figures – Which one are you?

  5. BMI Figures • Men Women • 19.8 18.8 • 21.1 19.3 • 22.2 20.9 • 23.6 23.1 • 25.8 26.2 • 28.1 29.9 • 31.5 34.3 • 35.2 38.6 • 41.5 45.4

  6. What is my BMI? • Calculate using the formula: BMI = weight in pounds x 703 (height, inches)2 • Use an online BMI calculator/ or BMI chart

  7. Energy Balance • Goal is for the energy taken in to equal the energy output • energy in = • energy out =

  8. Energy/Caloric Needs • Depend Upon: • Weight • Activity Level • Lean body mass (muscle) • Gender • Metabolism

  9. Planning a Healthy Diet • Compare intake to RDA • Follow general diet planning principles • Use the Food Pyramid to guide intake and activity

  10. Diet-Planning Principles (6) • Adequacy • Balance • Variety • Nutrient density • Kcal/energy control • Moderation • By following 2-3 of these you can improve your diet significantly - select the ones that “speak” to you!

  11. Diet-Planning Principles (6) • Adequacy • diet that provides enough energy and nutrients to meet the needs of healthy people

Diet-Planning Principles (6) • Balance • Diet that provides enough, but not too much of each type of food • Don’t want overeating of one food type to “crowd” out intake of other nutrients…. • Variety • Diet that includes a wide selection of foods within each food group • Eat a variety of fruits, not just oranges

  13. Diet-Planning Principles (6) • Nutrient Density • Select foods that provide the most nutrients for the least number of calories (nutrient dense foods) • FF vs. baked potato…… • Other examples ??

  14. Diet-Planning Principles (6) • Kcal Control • Intake that meets nutritional needs without excess kcal intake • Moderation • Diet that limits intake of foods high in sugar and fat (and alcohol and salt)

  15. Diet-Planning Principles (6) • Adequacy • Balance • Variety • Nutrient density • Kcal/energy control • Moderation Which ones speak to you?

  16. Diet Planning Guides • Food Guide Pyramid • Foods within each food group provide similar nutrients and are from similar food sources • Food Pyramid 1/2005 • Revised to address health issues in the U.S. • Health issues such as…..

  26. Food Pyramid • Fats, oils, sweets, salt – use sparingly • Candy, soda, sugar, honey….. • Sugar • Processed foods • Often a source of salt and/or trans fats

  27. Food Pyramid • Physical Exercise • Be physically active for 30 – 60* minutes per day. • Goal is moderate to vigorous exercise • * 60 minutes for kids and teens

  28. Physical Activity Goals • 30-60 minutes of sustained moderate physical activity 5x per week. • Walking, cycling • Shooting baskets • Pushing a stroller • Swimming laps • Gardening……..

  29. Physical Activity in U.S. Trends • Inactivity increases with age • Physical inactivity is more common in • Women • Those with less education • Those with a lower income.

  30. Physical Activity in Maine • < 25% of Mainers report engaging in regular physical activity

  31. Why is this all this important? • Obesity is on the rise. • Diabetes, even in teens, is on the rise. • Heart disease is on the rise. • Hypertension is on the rise. • A quality nutritional intake combined with regular physical activity can reverse these trends.

  37. Benefits Physical Activity and Healthy Weight • Reduced risk of: • Heart disease • Type II diabetes • High blood pressure • Obesity • Osteoarthritis • Dying prematurely!

  38. What are the Causes? • What factors contribute to a poor diet and obesity: • In your life? • AT UMA? • What factors contribute to a healthy diet and lifestyle: • In your life? • At UMA?

  39. What are the Solutions? • Improve quality of intake by: • Improve quantity of intake by: • Increase activity level by:

  40. Improving quality of intake • Increase intake of: • Whole grains • Fruits (but not juices) • Vegetables

  41. Improving quality of intake • Reduce your intake of: • Cheese • Trans fats • High fat choices • Goal is less than 3 g fat/serving

  42. Improving quality of intake • How do I do this? • Replace 2-3 foods in your diet with healthier choices. • Reduce fat content of milk • Turkey sandwich with mustard instead of roast beef with mayo. • Low fat popcorn instead of chips

  43. Maintaining a Healthy Weight • Reduce portion size • Reduce fat content of intake • especially saturated fats • Keep physically active • Build lean body mass – muscle • Weight bearing exercise • Walking

  44. Small changes can make a significant difference!

  45. Physical Activity and Health • Greater health benefits occur with increased duration, intensity, or frequency of physical activity.
