The Claim
A 10- to 12-week well-formulated ketogenic diet is associated with a 32% increase in brain-derived neurotrophic factor (BDNF) and a 52% reduction in leptin levels 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 with major depressive disorder, a 10- to 12-week ketogenic diet is associated with a 32% increase in brain-derived neurotrophic factor and a 52% decrease in leptin levels.
See the scientific wording
A 10- to 12-week well-formulated ketogenic diet is associated with a 32% increase in brain-derived neurotrophic factor (BDNF) and a 52% reduction in leptin levels in college students with major depressive disorder, suggesting metabolic and neurotrophic pathways may be involved in mood regulation.
When the body burns fat instead of sugar for fuel, it produces ketones that calm inflammation in the brain, which allows more brain-growth protein to be made. At the same time, fat tissue stops releasing as much of a hormone that signals fullness, which helps the brain reset its mood circuits.
What the research says
1 studyIn a small study, depressed college students who ate a keto diet for 10–12 weeks had more of a brain-growth protein (BDNF) and less of a fat-related hormone (leptin), just like the claim said.
