Anorexia Nervosa, Atypical Anorexia Nervosa, Atypical Bulimia Nervosa, Bulimia Nervosa
Conditions
Brief summary
This study will investigate the effects of ketone supplementation on eating behavior including drive to binge eat or restrict, mood and anxiety in individuals with anorexia or bulimia nervosa. In addition, the investigators will contrast the effects of active ketone supplementation versus placebo on electroencephalogram (EEG) measurement. All subjects enrolled in the study will undergo EEG on two consecutive days at the beginning of the study, after active ketone supplementation or placebo drink, matched in taste to the ketone drink. Days will be randomized. Thereafter, all subjects will take the ketone supplementation drink for two weeks, twice daily.
Detailed description
The goals of the study are: 1\) to test the effect of BHB as a nutritional supplement for AN and BN and 2) to test the ingestion of BHB on brain function. Subjects will complete a battery of self-assessments and a diagnostic assessment in order to determine eligibility and for characterization of behavior to be used in later analyses. After eligibility is confirmed, subjects will complete 2 EEG scans on separate days after ingestion of Ketone supplement drink or placebo and will complete a taste reward task during the EEG scan. Subjects will then complete 2 weeks of daily ketone supplementation and self-assessments.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Eating Disorders Inventory 3 Drive for Thinness Subscale | Change from baseline to study completion, up to 2 weeks | The Eating Disorders Inventory 3 is a self report assessment that measures core eating disorder symptoms. Subjects will complete this measure at the beginning and end of the study and the investigator will measure the change in scores. The Drive for Thinness Subscale has a range of 0 to 28 where higher scores mean worse outcome. |
| Eating Disorders Inventory 3 (EDI-3) Body Dissatisfaction Subscale | Change from baseline to study completion, up to 2 weeks | The Eating Disorders Inventory 3 is a self report assessment that measures core eating disorder symptoms. Subjects will complete this measure at the beginning and end of the study and the investigator will measure the change in scores. The Drive for Thinness Subscale has a range of 0 to 40 where higher scores mean worse outcome. |
| Weight Change | Change in body mass index from baseline to study completion, up to 2 weeks] | Body Mass Index over time as a measure of food intake from the start to end of the study |
