  1. Exercise & Healthy Weight Lossby Justin Lawler Spring 2009 Biggest Loser Wellness Workshop

  2. Workshop Overview • Factors contributing to obesity • Exercise Prescription for Weight Management • Successful weight control • Activity selection • Spot Reduction • Weight loss plateaus & pitfalls • Attitude adjustment

  3. Obesity Epidemic • National statistics from 1999-2000 revealed that obesity rates soared to 30.9% whereas in 1960 only 13.4% of American adults were obese. • Being obese is described as having a BMI ≥ 30kg . M2 for the general population • Negative health consequences can follow with a BM I in the “obese” range.

  4. Causes of Obesity • Many factors can be attributed to obesity, ultimately a positive caloric balance (taking in more calories than are expended) leads to obesity • Genetics • Lifestyle • Food intake & types of food eaten • Daily Caloric Expenditure

  5. Maintaining a Healthy Weight • Assessing Daily Caloric Need (# of calories needed to sustain current weight) assuming activity levels stay the same.

  6. How to gain, lose, or maintain your weight? It’s as simple as an equation! • Simple formula: • If your caloric intake from food is……… = (RMR + Calories from Activity + Thermic effect of food) then you will maintain your weight > (RMR + Calories from Activity + Thermic effect of food)then you gain weight < (RMR + Calories from Activity + Thermic effect of food)then you will lose weight

  7. Calculating Resting Metabolic Rate • Resting Metabolic Rate (Calories/Day) =370 + (21.6 x fat free mass in kg) • Example: a man weighs 220lbs (100 kg) and has a body fat percentage of 20%. His fat mass would be 20kg and his lean mass would be 80kg. • His RMR would be 370 + (21.6 x 80) = he burns 2098 calories/day without any exercise!

  8. Successful Weight Control • It’s not just cutting calories! • There needs to be a balance between the # of calories consumed and the # burned – this requires exercise! • Regular physical activity, along with healthy eating is much more effective at keeping the weight off in the long run than any diet.

  9. Successful Weight Control • Aerobic Exercise • Elevates metabolism during & after • Strength Training • Helps to build lean muscle • Good eating & good exercise = success! • 1-2 pounds/week safely (this equates to a caloric deficit of 3500-7000 per week) • Set realistic goals & start slowly

  10. Combined Approach for Weight Loss • ACSM recommends a combined approach of exercise and moderate caloric restriction for people attempting weight loss • Specific Recommendations for weight loss with exercise: • Frequency 5-7 days • Intensity: initially moderate (40-60% of HRR), then progressing to higher intensity (50%-75% of HRR) • Duration progress from short, easily tolerated bouts to 45-60 minutes daily.

  11. Calorie Burners!

  12. Some Alternative Exercises… • Mountain Biking • In-Line Skating • Walking • Dancing • Hiking • Boxing • Cross-country Skiing • Water Sports & Swimming

  13. Can I Spot Reduce? • Exercises that focus on a certain area may improve the tone or endurance of the muscles, but they don’t burn fat!  • Aerobic exercise is needed to elevate the heart rate and burn fat. • As a person establishes a caloric deficit through regular aerobic exercise, fat loss occurs all over the body, not just the parts you want to see the decrease!

  14. Plateaus & Pitfalls • Weight-Loss Woes • Determine the cause-balance the equation! • Exercise Your Options • Increase amount of time spent exercising or the intensity • Get Off the Plateau • Vary your program – shake things up & keep motivated! • Things to keep you on track: • Keep Records • Planning Meals/Snacks (portion control & consistent meals) • Establishing a support system • Goal setting with outcome-oriented goals • Designing a reward system-purchase new clothes, buying hobby items, taking a trip, attending special events, etc. • Watch out for gimmicks that promise unrealistic or unhealthy weight loss. • Even if not harmful, they do not lead to weight loss. This is achieved through regular exercise & good nutrition!

  15. Adjust your Attitude • “Restricting calories is the best way to lose weight.” • Healthy relaxed eating in response to hunger and satiety cues is the key to developing a comfortable relationship with food & avoiding eating disorders. • “Exercise is necessary to lose and keep weight off.” • Exercise is an excellent way to improve one’s health and enhance quality of life.

  16. Key Reminders • Don’t start out too hard or too fast or you may injure yourself or quit before enjoying any benefit. • Always concentrate on enjoying yourself, rather than on what a particular exercise might do for you. • Keep your exercise comfortable and only increase intensity after your body becomes accustomed to new activity levels.
