Midlife Belly Fat May Signal Alzheimer's Risk Decades Early

A new study links increased belly fat, particularly visceral fat, to early signs of Alzheimer's disease, such as amyloid plaques and tau tangles, in individuals as young as their 40s and 50s. This type of fat, which surrounds major organs, is associated with inflammation and insulin resistance, contributing to brain atrophy and reduced blood flow in the hippocampus, a key memory center. Experts suggest focusing on reducing visceral fat through exercise and monitoring body composition to potentially delay or prevent Alzheimer's symptoms.
