The Claim

Metabolic interventions such as ketogenic diets exert clinically meaningful antidepressant effects comparable to conventional therapies in individuals with major depressive disorder, as measured by symptom reduction magnitude.

Cause and effect
1 study reviewed
In plain English

Ketogenic diets produce a reduction in depressive symptoms in people with major depressive disorder that is similar in size to the reduction seen with standard antidepressant treatments.

See the scientific wording

Metabolic interventions such as ketogenic diets may exert clinically meaningful antidepressant effects comparable to conventional therapies in individuals with major depressive disorder, based on symptom reduction magnitude observed in a pilot cohort.

Why this might work

When the body runs on ketones instead of sugar, it reduces inflammation in the brain, which allows brain cells to grow new connections and repair themselves more effectively, leading to improved mood.

  1. Study: Critical appraisal of a pilot study examining a ketogenic diet as an adjunct therapy in college students with major depressive disorder

    In a small group of college students with depression, eating a very low-carb ketogenic diet for 10–12 weeks made their depression symptoms drop by nearly 70%, which is as big a drop as what you usually see with antidepressant pills. This suggests diet might help as much as medicine, but more research is needed to be sure.
