Treating severe obesity is challenging. With a society that emphasizes thinness, being severely obese takes a toll, both physically and emotionally. Unfortunately, the number of people with severe obesity continues to grow. Since most diets fail, how do we successfully treat those with severe obesity? Available treatment options include behavioral, pharmacological, and surgical interventions. Registered dietitian nutritionists play an integral role in guiding the nutrition care of people with severe obesity for all types of interventions. This continuing education course will update knowledge about weight-loss medications and bariatric surgeries and nutritional guidelines, and provide tools to dietitians so they can help their clients successfully achieve their goals.


The goal of this course is to educate dietitians and other healthcare providers on the prevalence, causes, consequences, and treatments of severe obesity. After studying the information presented here, you will be able to:
  • Define severe obesity and explain the causes for it
  • Compare and contrast the risk for disease between those with obesity and those with severe obesity
  • Explain the biological mechanism that likely accounts for the increased metabolic disturbances associated with visceral obesity
  • Outline the role that severe obesity plays in various diseases
  • Define binge eating disorder (BED) and its relationship to severe obesity
  • Discuss the psychological aspects of severe obesity
  • Describe the eating and exercise habits of National Weight Control Registry participants who have achieved and maintained weight loss
  • Discuss the safety and effectiveness of VLCD
  • Compare and contrast the types of weight loss medications available and discuss the safety and effectiveness of each
  • Compare and contrast the types of bariatric surgeries available and discuss the safety and effectiveness of each type of surgery
  • Identify the nutrient deficiencies expected based on the anatomical changes created by the various bariatric surgeries and the vitamin and mineral recommendations for patients who have undergone bariatric surgery
  • Identify the types and amounts of foods likely to produce problems in severely obese individuals who have received bariatric surgery
  • Discuss the diet progression after bariatric surgery and the rationale behind each diet
  • Describe techniques that may be helpful when counseling the severely obese
  • Compare and contrast the treatment methods used for severely obese children/adolescents and severely obese adults
