Intervention model description: Randomised controlled trial
Primary purpose: TREATMENT

Brief summary: This randomised controlled trial will evaluate the effect of a ketogenic diet vs a conventional diet on the symptoms of patients living with anxiety disorders using a validate self-reported inventory.

Detailed description: It has been theorized that ketogenic diet could improve symptom control in patients living with anxiety disorders. Animal models support this hypothesis but to this date, studies in humans are lacking.

The investigators will randomise patients with a confirmed diagnosis of anxiety disorders to follow a ketogenic diet (\<50 grs of carbohydrate per day) or a conventional diet (50% carbohydrate, 30% lipids, 20% protein) for one month.

Symptom control will be assessed weekly using Beck's inventory for Anxiety. Diet adherence will be measured using standardised food frequency logs and acetoacetate urine strips.

Eligibility criteria: Inclusion Criteria:

* Patients with a confirmed diagnosis of Anxiety Disorder by Psychiatrist.

Exclusion Criteria:

* Patients with the diagnosis of drug abuse, cognitive impairment or dementia, porphyria, carnitine translocase deficiency and carnitine palmitoyl transferase deficiency.
