Worldwide Trends in Body Mass Index (BMI)
Worldwide BMI Nearly Tripled since 1975
• Expansion of US food companies
• Developed countries decreasing % of income spent on food
• Decrease in home-cooked meals
• Increase in popular quick-weight loss diets
• Increase in research on what to do• Standard Behavioral Weight Loss (BWL)
• Slow, modest weight loss can be maintained
![Page 3: The Key to Successful Weight Maintenance Key... · •Some patients check weight at home and report it • Warn against checking weight more than once per week • Too much natural](https://reader033.vdocuments.us/reader033/viewer/2022042316/5f048ad07e708231d40e7c7d/html5/thumbnails/3.jpg)
Standard Behavioral Weight Loss (BWL) Treatment
• Read food labels
• Increase low fat dairy products, decrease sodium
• Eat low calorie foods
• Eat enough protein and fiber. This can make you feel fuller
• Increase variety of foods
• Eat more fruits, vegetables, and whole grains
• Decreased refined carbohydrates and white potatoes
• Eat leaner cuts of meat and lower fat dairy products
• Limit your intake of fried foods and other foods high in fat
• Watch your portion sizes
• Drink water instead of other beverages that are high in calories. These include non-diet sodas and most juices
• Increase activity level, sweat, at least 30-60 minutes every day

Standard Behavioral Weight Loss (BWL) Treatment
• Works for weight loss• No particular weight loss diet is
more effective
• Difficult to adhere to
• Weight loss plateaus• Metabolism decreases to protect
from weight loss
• Patient blame self for lack of long term success
• Regain weight when no longer following diet
• May lead to diet/binge cycle
• Can trigger eating disorders
• Exercise requirements• Overwhelm
• Discourage

Why is there an Obesity Epidemic▪ Changes in Food Environment
▪ Availability of cheap, high calorie foods▪ Large portions at restaurants
▪ Genetics▪ 50% of variance
▪ Aging▪ Reduced calorie needs
▪ Exercise: insignificant weight loss▪ Increased physical activity reduces energy
spent on other physiological activities
▪ Diets: transient reduction in weight▪ Rebound weight gain▪ Adaptive thermogenesis (decreased resting
metabolic rate)▪ Settling Point: defense of highest weight▪ Increase in Binge Eating
• All Diets: transient reduction in weight• Low fat• Low carbohydrate
• No sugar• No white carbs• No flour
• High protein• Paleo diet• Ketogenic• Vegetarian/Vegan• Clean food
• Fasting: transient reduction in weight• Intermittent fasting• Ramadan fasting*

Why? Adaptation to Famine
• Genetic tendency toward obesity in modern people• Resist weight loss
• Conserve energy
• Low metabolism
• Drive to feast (overeat, binge)
• Thrifty gene
• Behavioral adaptation• Obesity associated with wealth or
fertility

What Doesn’t Work
• Restrictive Diets• Fad diets• Advice to eat healthy
• Exercise• No effect on calorie
balance• Exercise requirements
lead to dropouts
• Rapid Weight Loss• Not maintained
• Weight loss medications without dietary changes
• Bariatric surgery without dietary changes
• Not Addressing Eating Disordered Behavior• Binge eating• Restricting
• Shaming
• Blaming
• Giving the same old advice• Eat healthy• Exercise more

Weight Loss Medication
• A number of medications are approved by the US Food and Drug Administration (FDA) for the treatment of overweight or obesity • Decrease appetite• Increase fullness
• Orlistat, Lorcaserin, Phentermine-topiramate, Bupropion-naltrexone, Liraglutide, Benzphetamin, Diethylpropion, Phentermine, Phendimetrazine
• All have significant side effects• High dropout rates
• Non effective if NOT combined with dietary changes• Little long-term evidence of efficacy
•

Bariatric Surgery
• Surgical management of severe obesity• Decrease appetite• Increase fullness
• Deficiencies of micronutrients• Treated with supplements
• To maintain weight loss (“not an easy way out”)• 3 meals/day• Moderate-sized meals• Little to no eating between meals• No emotional eating
• Average weight loss 100 to 120 lb (45 to 54 kg)
• Maintenance of 50-75% reduction in excess BMI
• Significant improvement in diabetes and cardiovascular disease, hypertension, cancer, sleep apnea, reflux

Behavioral Weight Loss-Enhanced (BWL-E)How to do it
• Start with current diet• Start high (calories)• Go slow (no decrease in calories if
losing a pound a month)• 10 lbs/year 5 kg/year
• Aim low to maximize health benefits• 5-10% of body weight
• Unless weight is dropping naturally and is consistent with weight/family history
• Stop• Maintain sustainable approach to
eating• Let weight be
• No pressure to exercise• Acknowledge
• Lack of effect on weight • Health benefits
• Eat in a pleasurable old fashioned way• Solid meals• Desserts with meal• Minimize snack (“gateway” for eating)
• Children need after school snack• Adults may not need snack
• Respect for patients in higher weight bodies• Acknowledge that genetics is the main
cause
![Page 15: The Key to Successful Weight Maintenance Key... · •Some patients check weight at home and report it • Warn against checking weight more than once per week • Too much natural](https://reader033.vdocuments.us/reader033/viewer/2022042316/5f048ad07e708231d40e7c7d/html5/thumbnails/15.jpg)
BWL-E Approach
• Regular meals and snacks • Food plans• 3 meals• 0-3 “intuitive” snacks• No judgment about food choices• Fun Food (“Save room for dessert”)
• No bad/forbidden foods• Except moldy food
• Parents oversee feeding of children & adolescents • Until child/adolescent demonstrates
competency
• No weight checks until easily following the “Plan”• “Tweak” Plan for slow weight loss

What Works(BWL-E)
• Diet• Breakfast• Permissive Flexibility• Effect of indulgence• Not telling people to eat
healthy• Targeting emotional eating
• Exercise• Important for health• Subjects eat better if they
regularly exercise• May help with weight loss
maintenance• Exercise requirements lead
to dropouts
• Reasonable Goals• 5% weight loss improves
health outcomes
• Support• Non-stigmatizing approach• One-on-one
consultation/group?
• Accountability• Weight checks• Weight graphs• Food behavior self-monitoring
• Weight loss medications + BWL-E
• Bariatric surgery + BWL-E

BWL-E Treatment Approach
1. First treat eating disordered behaviors (restrictive eating, bingeing)
2. Start high• Doable diet • “Choose healthiest diet you enjoy, stick to it, let weight be as it may.”
3. Go slowTweak plan to achieve 1 lb /.5 kg per month weight loss
4. Stop• Maintain sustainable approach to eating• Let weight be as is (genetics, weight history, no eating disordered behaviors)• Plan that led to weight loss is plan will maintain weight loss
• Calorie needs go down with weight loss• Aging decreases calorie needs
• Body neutrality/acceptance/respect for patient and their struggles• Negative body image associated with emotional eating
![Page 18: The Key to Successful Weight Maintenance Key... · •Some patients check weight at home and report it • Warn against checking weight more than once per week • Too much natural](https://reader033.vdocuments.us/reader033/viewer/2022042316/5f048ad07e708231d40e7c7d/html5/thumbnails/18.jpg)
Clinical Experience & Recommendations:Long-Term Weight Loss Maintenance (WLM)• Agnostic about cause of overeating
• Sympathetic about difficulty of eating moderately in current food environment• How to have one serving of carbs when 6 types are served
• No focus on weight loss first year or until abstaining from overeating• Stop dieting• No weight checks
• Dessert/Fun food is an essential food group• Must include pleasurable food with meals twice a day
• Problem-solving eating events • family, social, business, restaurants, festivals
![Page 19: The Key to Successful Weight Maintenance Key... · •Some patients check weight at home and report it • Warn against checking weight more than once per week • Too much natural](https://reader033.vdocuments.us/reader033/viewer/2022042316/5f048ad07e708231d40e7c7d/html5/thumbnails/19.jpg)
Managing Weight for Weight Loss
• “The scale is how you body speaks to me”• Weights taken “facing forward”
• My preference • Recommended by CBT-E
• Some patients check weight at home and report it• Warn against checking weight more than once per week• Too much natural variance
• 5 lb over the course of a day• 5 lb range for weight maintenance
• Make changes to usual dietary intake• 1 lb or ½ kilo/month• “I want you to lose weight on the highest calories possible
because you will be healthier and happier”• Address “off plan eating” first• 100 calorie decreases/week if weight not increasing 19

New Paradigm: Health at Every Size (HAES)
• Promotes improved health for people of all sizes without focus on weight
• Body positivity
• Promotes healthy eating, active lifestyle, weight neutral outcomes
• Diets don’t work: Results in stress, poor self-esteem, weight gain
• Weight fluctuations may cause harm• Increase cholesterol, blood pressure
• No health consequences associated with overweight or moderate obesity• US BMI categories lowered in 1998
![Page 22: The Key to Successful Weight Maintenance Key... · •Some patients check weight at home and report it • Warn against checking weight more than once per week • Too much natural](https://reader033.vdocuments.us/reader033/viewer/2022042316/5f048ad07e708231d40e7c7d/html5/thumbnails/22.jpg)
My Paradigm: Respect at Every Size (RAES)
• Respect and acceptance of people of all sizes • Necessary for success with patients of all sizes
• Body acceptance
• Increase understanding of the many factors that interfere with weight loss• “Settling Point” defense of the body’s highest adult weight• Genetic factors Body size is largely genetically determined• Food behaviors have to be slowly changed to have a long-term effect on
weight
• Willingness to provide best treatment without causing harm to those who want to lose weight to improve their health
