The Claim

The inverse association between dietary ketogenic ratio and depressive symptoms is partially mediated by body composition, with the body shape index (ABSI) accounting for 11.03% of the association through a protective effect, while BMI and waist circumference mediate adverse effects totaling 11.43–14.69% of the association.

How it works
1 study reviewed
In plain English

A higher ketogenic diet ratio is linked to lower depressive symptoms, and this link is partly explained by body shape index (ABSI), which reduces the association by 11.03%, while BMI and waist circumference increase the association by 11.43–14.69%.

See the scientific wording

The inverse association between dietary ketogenic ratio and depressive symptoms is partially mediated by body composition, specifically through the protective effect of the body shape index (ABSI), which accounts for 11.03% of the association, while traditional obesity measures like BMI and waist circumference mediate adverse effects totaling 11.43–14.69%.

Why this might work

Eating a ketogenic diet reduces fat around the organs and improves body shape, which lowers inflammation and stress signals in the brain, leading to fewer depressive symptoms.

  1. Study: Association between dietary ketogenic ratio and depressive symptoms: A population-based cross-sectional study using 2007-2018 NHANES data.

    This study found that people who eat more like a ketogenic diet are less likely to be depressed, and part of why this happens is because of how their body fat is shaped—better shape (ABSI) helps, but more overall fat (BMI, waist size) hurts. The numbers match exactly what the claim says.
