Brief Summary
Depression is a debilitating chronic illness affecting 1 in 6 adults in the United Kingdom (UK) at any one time. Antidepressants and psychological therapy are the main treatments, but some people do not respond to these. Neurons and signals in the brain are greatly disrupted in people with severe depression. A ketogenic diet, a high-fat and very low-carbohydrate diet, supplies a form of energy that appears to help brain cells communicate and may improve the treatment of depression. Our goal is to find out whether a ketogenic diet could be an additional effective treatment for patients with depression for which antidepressants do not work. Using social media advertising, 100 patients, ages 18-65, who have previously tried at least two different antidepressant medications within the current depressive episode will be recruited. Enrolment, consent, and data collection will be collected online using self-report questionnaires. Participants will be allocated by minimisation 1:1 to the KD group or control group based on depressive severity (moderately severe vs. severe) and body mass index (\<30kg/m2 vs. 30+ kg/m2). The intervention group will receive 6-weeks of prepared ketogenic diet meals (3 meals with snacks per day) and weekly ketogenic diet-focused nutrition counselling. The control group will be asked to follow a diet to reduce their saturated fat intake and increase vegetable consumption by one portion a day. The control group will receive vouchers to assist with purchases and will be provided with weekly nutritional counselling. Existing treatment for depression will remain in both groups. The primary outcome is the change in depression symptoms at six weeks. All participants will complete assessments of depression and anxiety every two weeks, starting before treatment to post-intervention (week 6), and again at week 12. Additional outcomes include participants' ability to experience pleasure, quality of life, ability to socialise and work, cognitive processing, morning cortisol, and gut microbiome. At all stages of the study, adults with lived experience of depression will advise the research team to take into account the needs and views of patients. This study will provide evidence of whether following a ketogenic diet leads to a short-term improvement in depression in people whose depression cannot be relieved by antidepressants.

Outcome Measures
Primary Outcomes (1)
Patient Health Questionnaire (PHQ-9)
The PHQ-9 is a previously validated and reliably self-administered 9-item questionnaire of depression severity corresponding to Diagnostic Statistical Manual 5th Edition (DSM-V) criteria for major depressive disorder. Items are scored on a 4-point scale from "0" = not at all to "3" = nearly every day. Total scores range from 0 to 27 with higher scores reflecting increased depression severity. PHQ-9 scores of 5, 10, 15, and 20 represent mild, moderate, moderately severe, and severe depression, respectively.

Study Arms (2)
Ketogenic Diet (KD)
EXPERIMENTALParticipants allocated to this condition will receive 6-weeks of home-delivered pre-prepared ketogenic diet (KD) meals (3 meals/day, snacks) from a vetted ketogenic diet food supplier. The 6-week intervention includes a weekly 30-minute dietary counselling call with a registered dietitian to support following a ketogenic diet. Participants receive educational materials with information about foods that are compatible with the diet, common symptoms and how to manage them, and strategies to help maintain the diet during and after the 6-week intervention period.
Phytonutrient Diet (PD)
PLACEBO COMPARATORParticipants in the control group will receive weekly 30-minute dietary counselling with a registered dietitian and be asked to increase vegetable consumption and reduce saturated fat intake as part of a phytonutrient diet (PD). Participants will receive food vouchers every 2-weeks to help purchase food items or replacements that support high vegetable, low saturated fat intake. This aims to be a plausible placebo dietary treatment for depression. There is no clear evidence that these manipulations will change depression severity. The dietitian will provide materials to explain the diet and suggest foods by colour with supporting recipe suggestions.
Interventions
A Ketogenic Diet (KD) is a high-fat and very low-carbohydrate intake. Participants will follow a modified KD (estimated 20-50g carbohydrates/day based on a 2000 kcal diet) without energy restriction. Participants will test for ketosis in their morning urine at least twice a week to monitor adherence. To support adherence in people with depression, delivered pre-prepared KD meals (3 meals per day) and additional ketogenic snacks will be sent to participants. A registered dietitian will provide weekly 30-minute nutritional counselling sessions. The dietitian will schedule appointments and assess the participants' experience with adhering to the KD diet, troubleshoot as required, give guidance on how to prevent or overcome side effects of KD diets, and keep record of participants' ketosis level and suicide risk.
Participants in the control group will receive the same degree of dietetic input and be told that their diet is a modified fat and phytonutrient diet. The photo diet aims to increase vegetable consumption, reduce saturated fat intake and increase poly- and mono-unsaturated fat intake. Participants in the control group will receive food vouchers (£20 every two weeks) to help purchase these items. This aims to be a plausible placebo dietary treatment for depression. There is no clear evidence that these manipulations will change depression severity. The dietitian will create written materials to explain the diet and suggest foods by colour with supporting recipe suggestions.

- Aged 18-65 years
- Have been diagnosed with depression
- Currently on an antidepressant medication for a period of 4-weeks or longer
- Have tried 2 or more antidepressant treatment trials of adequate dose and duration within the current depressive episode to which they did not fully respond. An adequate treatment trial is defined as at least 4 weeks of a medication at a minimum National Institute for Health and Care Excellence (NICE) approved dose
- With a Patient Health Questionnaire-9 (PHQ-9) total score greater than or equal to 15 at baseline

- Have both a fridge and a freezer at home
- Complete all baseline assessments
You may not qualify if:
- Currently following a low carbohydrate or ketogenic diet
- Currently following a vegan or vegetarian diet as these diets are more challenging to accommodate in a Ketogenic Diet and adding vegetables in the control group is unlikely to be seen as helpful.

- Women who are pregnant, planning pregnancy in the next three months, or breastfeeding
- Have a body mass index (BMI) of \<18.5 kg/m2
- Have unstable or severe medical conditions (e.g., cancer, cardiovascular, renal, lung, psychiatric, or bleeding disorders, diabetes, etc.), currently receiving cancer treatment except hormonal treatment for breast cancer or non-melanoma skin cancer treatment
