Discussion: Regulation of Metabolism and Eating Disorders

People who are overweight or obese are at a disadvantage in several respects. For example, they have an increased risk of a variety of chronic illnesses, such as heart disease and diabetes. But there is also a fair amount of prejudice against those who are overweight or obese. This bias may contribute to negative evaluations by others and low self-esteem on the part of the person who is overweight. The negative attitudes may exist because the culture seems to place a great deal of responsibility on the individual for his or her weight.

Just how much control do you have over your own weight? In this Discussion, you will review the research regarding biological factors contributing to eating behaviors, weight, metabolism, and BMI. Then, you will consider how these factors apply to eating disorders.

To prepare for this Discussion:

• Review the Learning Resources focusing on the biology of eating disorders.

By Day 3

Post a description of the brain basis of eating behaviors. That description should detail the brain regions that promote eating and satiety, as well as the neurotransmitters and hormones that are involved in these behaviors. Briefly discuss the effectiveness or ineffectiveness of reducing caloric intake to lose weight. Then, based on your last name, you will summarize the current understanding of a particular eating disorder: obesity (last names starting with A–H); anorexia (last names starting with I–Q); or bulimia (last names starting with R–Z). Include what is currently understood about brain regions, hormones, or neurotransmitters involved with your disorder and talk about any existing treatment options. Then, based on your understanding of the biological factors that influence weight gain and homeostasis, you will propose a brain-based therapy for your disorder (i.e., drugs, genetic treatments, deep brain stimulation, etc.). Lastly, research suggests that many young people develop eating disorders based on comments from family and friends as well as social pressure. With that in mind, and based on your understanding of motivation factors related to eating and your understanding of eating disorders, propose an approach you might take to encourage a teenage friend or family member to eat healthily and NOT develop an eating disorder. You may include any relevant information from personal experiences, the Learning Resources, or other sources.

Support your postings and responses with specific references to the Learning Resources and any additional sources you identify using both in-text citations and complete references in APA format.
