One Type of Fat May Accelerate Brain Aging, But Scientists Say There's a Fix

A study of 533 adults linked higher visceral fat to faster brain aging, including more brain atrophy, larger ventricles, and lower cognitive scores.

People who maintained lower visceral fat over time showed better-preserved brain volume, suggesting fat loss may help protect the brain.

Blood sugar and insulin-related changes may partly explain the connection, pointing to a modifiable midlife risk factor beyond overall weight loss.
