What this trial is about
This study aims to determine whether a keto-like supplement relative to placebo results in functional brain changes during fMRI tasks evaluating positive and negative valence in individuals with moderate to severe depression. In this double-blind randomized placebo-controlled trial, 75 individuals with a Patient Health Questionnaire (PHQ-9) scale score ≥ 10 (MDD) will be enrolled to participate in an 8-week treatment study to obtain 60 completers. Participants will be randomized with a 1-1 ratio to receive the keto-like supplement (n= 30 completers) or placebo (n=30 completers) taken orally three times per day for 8 weeks. Participants will undergo a 10.5-hour screening/baseline evaluation visit split over 2 days at week 0 including questionnaires, neuroimaging before and after supplement or placebo administration and blood draws, office visits at week 2 (1.5 hours), week 4 (3 hours), week 6 (0.5 hours), week 8 (6 hours), a follow-up visit at week 10 (1.5 hours) and two phone calls between visits (weeks 1 and 3) during which a brief clinical assessment will be obtained (10 minutes each). The total time involved in the study is approximately 23.5 hours.

- Has received an investigational drug/vaccines, used an invasive investigational medical device within 60 days before the planned first dose of the keto-like supplement or has participated in 2 or more interventional clinical studies in the previous 1 year, or is currently enrolled in any drug or non-drug interventional study.
- Has had major surgery, (i.e. requiring general anesthesia) within 12 weeks before screening, or will not have fully recovered from surgery, or has surgery planned during the time they are expected to participate in the study.
- Intake of Omega 3 fatty acids (DHA, EPA, fish oil supplements)
- Significant cognitive impairment, clinically relevant or progressive disease (e.g., liver, kidney, cardiovascular system, respiratory tract, vascular system, brain, metabolism, thyroid) that could affect the course of the study

- Currently practicing a ketogenic or paleo diet or planning to do so during the study period.
- Change in body weight of more than 5 kg within one month before the start of the intervention
