The Claim
In euthymic adults with bipolar disorder, a 6- to 8-week ketogenic diet is associated with an 11.6% reduction in brain glutamate plus glutamine concentration in the anterior cingulate cortex and a 13.6% reduction in the posterior cingulate cortex.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In adults with bipolar disorder who are not currently experiencing mood episodes, following a ketogenic diet for 6 to 8 weeks is associated with a measurable decrease in glutamate and glutamine levels in two brain regions involved in mood regulation.
See the scientific wording
In euthymic adults with bipolar disorder, a 6- to 8-week ketogenic diet is associated with a 11.6% reduction in brain glutamate plus glutamine (Glx) concentration in the anterior cingulate cortex and a 13.6% reduction in the posterior cingulate cortex, regions implicated in mood regulation.
When the body runs on ketones instead of sugar, brain cells use less glucose, which cuts down the production of glutamate, a chemical that excites brain cells. This lowers the levels of both glutamate and its related compound glutamine in mood-regulating brain areas.
What the research says
1 studyIn people with bipolar disorder who weren’t having mood swings, eating a keto diet for 6–8 weeks lowered levels of two brain chemicals (glutamate and glutamine) in areas linked to mood—just like the claim said. The study measured this directly and found the exact same percentage drops.
