The Claim
Gut microbiota composition differs between obese adults on a ketogenic diet and those on a Mediterranean diet, and these compositional differences are associated with distinct behavioral and metabolic outcomes in humans and mice.
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.
Obese individuals on a ketogenic diet have different gut bacteria than those on a Mediterranean diet, and these differences are linked to different patterns of behavior and metabolism in humans and mice.
See the scientific wording
The gut microbiota composition differs between obese adults following a ketogenic diet versus a Mediterranean diet, and these differences are associated with distinct behavioral and metabolic outcomes in humans and mice, suggesting microbiota may mediate diet effects on mental health.
What you eat changes the types of bacteria in your gut. These bacteria produce different chemicals based on your diet. Some of these chemicals enter your bloodstream and reach your brain, where they change the levels of brain chemicals that control mood and behavior. This leads to different mental health outcomes depending on the diet.
What the research says
1 studyPeople on the Mediterranean diet felt less depressed, while those on keto felt less impulsive. When scientists gave mice gut bacteria from keto dieters, the mice became anxious and had unusual brain chemicals — showing that gut bacteria might be how diet affects mood and behavior.
