Brief Summary of Protocol:
The purpose of this study is to examine the relationship of stress and eating patterns in normal weight and obese participants. In the United States alone, it is estimated that at least 40 million people have anxiety disorders and 70 million people are considered obese. Interestingly, many people tend to have symptoms of both anxiety and disordered eating at the same time, suggesting that there may be a connection between anxiety and food intake. It is not known if anxiety impairs an individual’s ability to diet, by increasing hunger and preference for foods rich in sugar and fat. In other words, we are trying to find out if dieting (fasting) increases anxiety and whether anxiety increases appetite, therefore creating a vicious cycle.

To better understand the relationship between anxiety and food, we are studying the effect of changes in food consumption on anxiety in obese and normal weight people. We will be studying people while fed and fasted and also when anxious. We expect that the findings of this study will provide us with more information about how someone’s nutritional state changes how the brain works and this may help us develop more effective treatments for obesity. Also, this study may give insight to anxiety and eating disorders.
