Approach to Lifestyle Modification—3 Separate Issues to Address • Heart Healthy Food Choices • DASH Diet, Mediterranean-style diet, etc • Unlikely to result in significant weight loss alone • Exercise for Life • Give specific advice (exercise prescription) • No recommendation for routine exercise treadmill testing in asymptomatic individuals • Start slowly, as little as 5 min/day, but work-up to at least 30 minutes of moderate intensity exercise daily • Work exercise into daily routineMultiple short bursts are appropriate for some patients • Mix of cardio and resistance training appropriate for most • Unlikely to result in significant weight loss alone, but crucial for weight maintenance • Calorie Manipulation for weight loss or maintenance

Reduce intake by: Key to Weight Loss: Calories in and Calories Out: To Achieve a 300 kcal Negative Energy Balance: Or increase activity by: Eliminating 2 oz potato chips Running 3 miles in 30 min or or Substituting 2 diet sodas for 2 regular sodas Bicycling 8 miles in 30 min

Practical Approach to Maximize Satiety and Achieve Meaningful Weight Loss and Weight Management • Individualized balance of Carbs / Fats / Protein for sustained adherence—Focus on FOOD • Right Fats (mono- and poly- unsaturated, omega 3’s • Right Carbs (high fiber, low glycemic index, complex • Right Protein (plant, marine, and lean animal sources) • Limit or eliminate sugar, high fructose corn syrup, and refined starches and snack foods • Reduce or eliminate all calories from beverages • Smaller portions, low energy density, high nutrient density • Consider book-keeping of calories, points, etc • Drink (and eat) water • Exercise for life • Get adequate sleep
Motivation: Stress level: Psychiatric issues: Time availability: Assess Readiness for Change Each Visit Patient seeks weight reduction Free of major life crises Free of severe depression, substance abuse, bulimia nervosa, other eating disorders Patient can devote 15-30 min/d to weight control for next 26 weeks YES NO Patient Ready? Initiate more aggressive weight loss therapy Prevent weight gain and explore barriers to weight reduction
