2 Session 3: Getting Your Patients to Weigh In: Discussing Approaches to Treating Obesity in the Primary Care Setting Learning Objectives 1. Summarize current recommendations for screening, assessment, and treatment goals in the management of adult obesity 2. Develop individualized therapeutic regimens for adults with obesity, incorporating lifestyle management and adjunct therapies as appropriate, based on current treatment recommendations and recent evidence 3. Utilize clinically validated approaches and tools to engage and support patients in the management of adult obesity as a chronic disease Faculty Donna H Ryan, MD Program Chair Professor Emerita Pennington Biomedical Research Center New Orleans, Louisiana Dr Donna Ryan is professor emerita at Pennington Biomedical Research Center, Baton Rouge, Louisiana. She served as associate executive director at Pennington Biomedical for 34 years; where she was active in research, teaching, and administration. Her research accomplishments include landmark studies of omega 3 fatty acids and membership on the team that developed the National Institutes of Health (NIH) sponsored feeding studies, Dietary Effects on Lipoproteins and Thrombogenic Activity (DELTA) and Dietary Approaches to Stop Hypertension (DASH). Dr Ryan was an investigator on NIH multicenter lifestyle intervention studies, including the Diabetes Prevention Program (DPP) study, the Preventing Overweight Using Novel Dietary Strategies (POUNDS Lost) study, and the Look AHEAD (Action for Health in Diabetes) trial. She also worked with the Louisiana office of group benefits to conduct the Louisiana Obese Subjects Study (LOSS): a pragmatic clinical trial of intensive medical therapy for severe obesity conducted in 6 Louisiana primary care clinics. This work continues in a translational phase as HEADS UP!. Dr Ryan was principal investigator for a military nutrition grant from 1988 to 2011 to develop improvements to soldier readiness, nutrition, and health. Dr Ryan served as cochair on the panel to revise the NIH supported, evidence based guidelines on the evaluation and management of overweight and obesity in adults. She is past president of The Obesity Society (TOS) and current associate editor in chief of TOS s journal, Obesity. She has authored more than 190 original publications and 45 books, chapters, and reviews; primarily in the field of obesity. Dr Ryan has served the scientific community as a reviewer and advisor in many capacities, such as the National Science Foundation medical research and development expenditures workshop (2006); the National Dairy Council review team for the Children s Hospital Oakland Research Institute (2006); chair of the Data Safety Monitoring Board (DSMB) for the NIH grant, Safety and Efficacy of Low and High Carbohydrate Diets (2002 to 2008); a member of the DSMB for EARLY Studies (2010 to the present); and as a reviewer for the European Union/European Federation of Pharmaceutical Industries and Associations innovative medicines initiative (2011 to 2012).

3 Holly Wyatt, MD Associate Professor of Medicine Division of Endocrinology, Metabolism and Diabetes Medical Director The Wellness Clinic Associate Director Anschutz Health and Wellness Center University of Colorado Denver, Anschutz Medical Campus Aurora, Colorado Dr Holly Wyatt is associate professor in the division of endocrinology, metabolism, and diabetes in the department of medicine at the University of Colorado Denver Anschutz Medical Campus. She received her undergraduate degree at The University of Texas and her medical doctorate from Baylor College of Medicine, Houston. Dr Wyatt completed her internal medicine and endocrinology training at the University of Colorado. She is a practicing physician and clinical researcher at the Anschutz Health and Wellness Center and is the medical director of the Wellness Clinic, which specializes in long-term strategies for weight management. Dr Wyatt has more than 18 years of clinical experience in weight reduction using behavioral treatment, dietary therapy, physical activity interventions, weight loss medications, and surgery. Recently, she became the medical expert for Season 4 of ABC s Extreme Weight Loss. Dr Wyatt has spent much of her research time investigating what makes people successful during their weight loss journey by following more than 10,000 successful losers in the National Weight Control Registry. She also has investigated the reasons why Colorado is the leanest state in the nation. Dr Wyatt s passion for and expertise in helping obese individuals successfully transform their bodies, minds, and lifestyles has made her a popular clinician, speaker, and obesity educator. She shares much of what she has learned in a new book she coauthored titled State of Slim: Fix Your Metabolism and Drop 20 Pounds in 8 Weeks on the Colorado Diet. Video Interaction Victoria A Catenacci, MD Assistant Professor of Medicine Department of Medicine Division of Endocrinology, Metabolism and Diabetes University of Colorado School of Medicine Aurora, Colorado Dr Victoria Catenacci earned her medical degree at Yale University School of Medicine and completed her residency in internal medicine at Yale-New Haven Hospital, where she served as chief resident. She completed her fellowship in endocrinology, metabolism, and diabetes at the University of Colorado School of Medicine; where she was appointed to a faculty position in She is currently assistant professor of medicine in the department of medicine, division of endocrinology, metabolism, and diabetes. Her areas of clinical focus are in general endocrinology and weight management. Dr Catenacci sees patients half a day per week in a general endocrine clinic at the University of Colorado Anschutz Outpatient Pavilion, where she treats a range of endocrine conditions, including diabetes, thyroid disease, metabolic bone disease, and lipid disorders. She also spends half a day per week seeing patients in a weight management clinic at the University of Colorado Anschutz Health and Wellness Center, where she focuses on individualized behavioral strategies for weight management along with the use of weight loss medications for appropriately selected patients. Dr Catenacci s primary research interest is in the role of physical activity in long-term weight loss maintenance. She has conducted several studies for the National Weight Control Registry that have provided information on the physical activity and dietary habits of successful weight loss maintainers. She has authored a comprehensive review on the role of physical activity in weight loss and maintenance, published in Nature Clinical Practice Endocrinology & Metabolism. Dr Catenacci has received a National Institutes of Health (NIH) F32 national research service award and an NIH K23 career Session 3
4 development award. She is currently the principal investigator for a 5 year NIH funded interventional trial designed to evaluate whether an exercise intervention timed after diet-induced weight loss (rather than initiated at the same time) improves exercise adherence and long term weight loss. She has also served as a subinvestigator on several industrysponsored weight loss medication trials.

Discussing Long-Term Weight Management With Patients: Pharmacological Agents Practice shared decision making with patient engage in discussion of potential risks/benefits and whether a medication is right for them PHARMACOTHERAPY Because obesity is a chronic disease, long-term management is required Pharmacological agents are used as an adjunct to lifestyle modification 1 Agents approved for short-term use 1,2 Modest weight loss ( 3-4 kg over 1 year) Should be discontinued after 12 weeks not approved for long-term use Agents approved for long-term use 1,2 Modest but clinically significant weight loss (5%-10%) Important to take as prescribed and monitor for efficacy and adverse effects Increase to maximum dose or discontinue if an agent is not effective a May consider an alternative agent if one is not effective Cost may not be covered by insurance a For all but orlistat, discontinue if 5% weight loss (4% with liraglutide 3.0 mg) is not achieved after 12 weeks on maximum/maintenance dose US FDA. 2.
