Brief Summary:
This Open-Label Pilot Study Aims to Determine Whether a Two-Part Sequenced Out Patient Procedure Utilizing a Modified Ketogenic Diet Followed by a Series of Titrated Ketamine Infusions Results in Improvement or Remission of Chronic Anorexia Nervosa in Adults with Symptoms of Anorexia for at Least 3 Years Despite Treatment Involving at Least 2 Different Modalities. The Hypothesis is That the Diet Addresses Core Metabolic Deficits in the "Anorexic Brain" and Primes the Response to Ketamine.

Condition or disease Intervention/treatment Phase
Anorexia Nervosa Drug: Ketamine Hcl 50Mg/Ml Inj Phase 1

Detailed Description:

Participants Who Are Deemed Eligible Will Participate in an Open-Label Clinical Trial Using a Sequenced Treatment Previously Reported in One Case Study to Result in Complete and Sustained Remission of Anorexia Nervosa for Over One Year (and Continuing).

Part 1 Involves a Group 2-Day Immersive In-Person Educational Program to Begin a Modified Ketogenic Diet, Under the Supervision of a Nutritionist Who Has Decades of Experience in Designing Ketogenic Diets for Seizure Patients. This Group Experience is Followed by a 4 Week Period of At-Home Adoption of the Diet, With Close Phone and E-Mail Follow-up.

Part 2 Involves Administration of a Series of Titrated Intravenous Ketamine Infusions Scheduled Over 2 Weeks.

During Part 1, and Part 2, There Will Be a Range of Objective and Psychological Measures To Assess Safety and Response. The Participants Will be Followed For 12 Months.
