The Claim

Urine ketone levels are not associated with changes in depression severity in adults with treatment-resistant depression following a ketogenic diet, indicating that the observed antidepressant effect is not mediated by ketosis.

How it works
1 study reviewed
In plain English

In adults with treatment-resistant depression who follow a ketogenic diet, the amount of ketones detected in urine does not change along with changes in depression symptoms, meaning ketosis is not the mechanism behind any mood improvement.

See the scientific wording

Ketone levels measured in urine are not associated with changes in depression severity in adults with treatment-resistant depression following a ketogenic diet, indicating that the observed antidepressant effect is not mediated by ketosis.

Why this might work

A low-carb diet changes brain chemistry in ways that improve mood, but this happens without increasing ketones in the urine. The mood improvement comes from other changes in the brain, not from ketones.

  1. Study: A Ketogenic Diet for Treatment-Resistant Depression

    The study found that people with severe depression felt better after eating a low-carb diet, but how much ketones they had in their urine didn’t predict whether they felt better or not — so ketones in urine aren’t what’s fixing their mood.
