In plain English

In adults with treatment-resistant depression, a ketogenic diet does not reduce depression symptoms more than a placebo after 6 weeks or after 12 weeks.

See the scientific wording

Ketogenic diets have no clinically significant effect on depression symptoms in adults with treatment-resistant depression beyond placebo after 6 weeks, and no effect after 12 weeks.

Why this might work

When the body burns fat instead of sugar for fuel, it produces ketones that replace glucose as the brain’s energy source. This change does not alter brain reward signals, stress hormone levels, or brain inflammation enough to improve depression symptoms in people who have not responded to other treatments.
