The Claim
A 10- to 12-week well-formulated ketogenic diet is associated with a 69–71% reduction in depressive symptom severity, as measured by PHQ-9 and HRSD scales, in college students with major depressive disorder.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In college students diagnosed with major depressive disorder, following a ketogenic diet for 10 to 12 weeks is associated with a 69–71% decrease in depressive symptoms as measured by standard clinical scales.
See the scientific wording
A 10- to 12-week well-formulated ketogenic diet is associated with a 69–71% reduction in depressive symptom severity, as measured by PHQ-9 and HRSD scales, in college students with major depressive disorder, suggesting metabolic interventions may contribute meaningfully to mood improvement in this population.
When the body runs on ketones instead of sugar, it calms down inflammation in the brain and makes more of a protein that helps brain cells connect and grow. This lets the parts of the brain that control mood work better, which reduces feelings of depression.
What the research says
1 studyA small study found that college students with depression who ate a low-carb, high-fat diet for 10–12 weeks felt significantly better—about 70% less depressed—suggesting that changing what you eat might help improve mood.
