Visceral Fat Linked to Alzheimer's Risk Decades Before Symptoms

New research shows that hidden belly fat correlates with early brain changes tied to Alzheimer's, highlighting the potential for prevention through lifestyle changes.

• A study presented at the Radiological Society of North America meeting found that visceral fat is strongly associated with amyloid and tau proteins, key markers of Alzheimer's disease.
• Researchers observed these links in middle-aged adults, decades before cognitive symptoms typically appear.
• Higher levels of visceral fat were connected to increased insulin resistance and lower HDL (good cholesterol), compounding Alzheimer's risk.
• The findings suggest that targeting visceral fat and related metabolic factors through lifestyle changes or medications could reduce Alzheimer's risk.
• This study emphasizes early intervention, as nearly 75% of Americans are overweight or obese, a significant public health concern.
