The Inspiration for this Research

Dr. Danan is a psychiatrist working towards in Toulouse, France. The inhabitants he serves is comprised primarily of individuals of French and North African descent with severe, persistent psychological sickness, lots of whom additionally undergo from metabolic sicknesses corresponding to weight problems, hypertension, and kind two diabetes.

After witnessing marked enchancment in seizures and autism behaviors in a member of the family inside a number of weeks of getting adopted a ketogenic food regimen, Dr. Danan got interested within the potential of the food regimen to enhance the psychiatric and metabolic standing of his most treatment-resistant sufferers, no matter prognosis. He created a metabolic psychiatry remedy program inside his native hospital the place sufferers with persistent psychological sickness who had exhausted normal psychiatric therapies might try a ketogenic food regimen in a supportive, medically supervised setting.

Ketogenic Weight loss program Protocol

Dr. Danan admitted 31 of his sufferers with main despair, bipolar dysfunction, or schizophrenia to the Clinique du Castelviel in Toulouse the place they had been served a ketogenic food regimen in lieu of ordinary hospital fare. This system he applied limits whole carbohydrate consumption to a most of 20 grams per day, and was based mostly on the ketogenic food regimen protocol utilized by Dr. Eric Westman in his metabolic analysis at Duke College. [A description of the diet is included in the Supplemental Data.]


Signs of despair and psychosis improved in all 28 sufferers who adopted the food regimen for longer than two weeks, with enhancements changing into noticeable inside three weeks or much less. 43% of sufferers achieved medical remission, and 64% had been discharged from the hospital on much less psychiatric remedy. Dr. Danan had by no means witnessed this diploma of enchancment earlier than in any of those sufferers—most of whom he had labored with for years and even many years, and all of whom had beforehand been hospitalized below his care a number of instances.

Sufferers additionally skilled important enhancements in markers of metabolic well being, together with blood stress, blood glucose, triglycerides, and weight:

All however one affected person misplaced weight together with 96% of those that had been taking antipsychotics, and almost half achieved clinically important weight reduction [defined as ≥5% reduction in body weight]. This welcome final result alone makes a compelling case for the implementation of the KD [ketogenic diet] in people who find themselves taking antipsychotic medicines, whether or not or not psychiatric signs enhance in response to the KD, as counteracting antipsychotic-induced weight achieve is extraordinarily tough.


Till now, the proof in help of ketogenic diets particularly for psychiatric situations has been restricted to speculation papers, animal research, and a small however rising variety of particular person case stories.

As this was not a managed trial, the extent to which the ketogenic food regimen could or could not have straight contributed to the outcomes reported can’t be ascertained. Nevertheless, since that is the primary time {that a} group of sufferers this huge and this diagnostically various has ever been handled with a ketogenic food regimen in a hospital setting, these medical observations serve to bridge the hole between present case stories and the managed medical trials already underway at different establishments all over the world.

When requested to mirror on his expertise as principal investigator of this research, Dr. Danan mentioned:

Throughout my profession, I’ve been struck by the boundaries of standard therapies in psychiatry. Most sufferers relapse and have a poor high quality of life. Most of them undergo from dramatic weight achieve, weight problems, diabetes, hypertension, and metabolic syndrome. Lack of life expectancy on this inhabitants might be measured in many years. It is a matter of public well being and way more consideration have to be paid to those issues.

Introducing dietary measures, significantly the ketogenic food regimen, helped me significantly to enhance the outcomes of remedy. Sufferers started bettering their metabolic standing by shedding weight, bettering blood stress, and so forth., however most significantly, I noticed actual enhancements of their psychiatric signs corresponding to hallucinations, delusions, and temper instability.

After having led this research I’m satisfied that dietary measures can have a profound impression and result in crucial advantages, which makes me say that this represents the longer term route to develop in psychiatric care.
