The Claim

In obese adults, the ketogenic diet is associated with increased brain levels of taurine, alanine, and betaine, and threonine levels correlate with behavioral changes.

Source: Ketogenic diet is less effective in ameliorating depression and anxiety in obesity than Mediterranean diet: A pilot study for exploring the GUT-brain axis.

In plain English

In obese adults, following a ketogenic diet is linked to higher levels of taurine, alanine, and betaine in the brain, and changes in threonine levels are linked to changes in behavior.

See the scientific wording

In obese adults, the ketogenic diet is associated with increased brain levels of taurine, alanine, and betaine, and threonine levels correlate with behavioral changes, suggesting specific metabolites may link dietary patterns to neural outcomes.

Why this might work

When someone eats a ketogenic diet, the bacteria in their gut change how they produce chemicals. Some of these chemicals enter the bloodstream, cross into the brain, and raise levels of taurine, alanine, and betaine. One chemical, threonine, changes how brain circuits control mood and behavior. This links what a person eats directly to how their brain functions.

  1. Study: Ketogenic diet is less effective in ameliorating depression and anxiety in obesity than Mediterranean diet: A pilot study for exploring the GUT-brain axis.

    People with obesity who ate a keto diet had gut bacteria that, when given to mice, made the mice have higher levels of certain brain chemicals (taurine, alanine, betaine) and changes in behavior linked to threonine. This suggests the diet can affect the brain through these chemicals.
