Ketogenic Diet in Weight Recovered Anorexia Nervosa to Normalize Brain Metabolism and Persistent Eating Disorder Psychopathology
This is a longitudinal study with an open design in weight recovered anorexia nervosa (wrAN) individuals. Healthy controls (HC) will also be assessed. Study participants will be carefully assessed and will have 18F-fluorodeoxyglucose (\[18F\]FDG) positron emission tomography (PET) scans for assessment of regional brain glucose uptake. The wrAN group will be compared to healthy controls. Participants in the wrAN group will then complete 14 weeks of therapeutic ketogenic diet (TKD). At the end of the TKD study, participants will have assessments and a second \[18F\]FDG and TMS/EEG scan. Study participants will be followed over six months after the intervention. This follow-up procedure will help determine whether symptom improvement will be stable or worsen in individuals who choose to continue or discontinue the TKD intervention. This will be a naturalistic follow-up.
