The Claim
In obese adults aged 18–65, a three-month Mediterranean diet results in a greater reduction in depressive symptoms compared to a ketogenic diet, with mean depression score reductions of 32% versus 14%.
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.
Among obese adults aged 18–65, following a Mediterranean diet for three months leads to a 32% reduction in depression scores, while a ketogenic diet leads to a 14% reduction.
See the scientific wording
In obese adults aged 18–65, a three-month Mediterranean diet leads to greater improvement in depressive symptoms compared to a ketogenic diet, with mean depression score reductions of 32% versus 14%, suggesting dietary pattern significantly influences mood outcomes in this population.
The food you eat changes the bacteria in your gut, which produce chemicals that travel to the brain and change how mood-related brain circuits work. A Mediterranean diet promotes bacteria that make chemicals leading to less depression, while a ketogenic diet promotes bacteria that make chemicals linked to more anxiety and depression.
What the research says
1 studyIn a small study, people with obesity who ate a Mediterranean diet for three months felt significantly less depressed than those on a keto diet — their depression scores dropped by 32% vs. 14%. So yes, the Mediterranean diet helped mood more.
