Obesity Accelerates Alzheimer's

A recent study indicates obesity may accelerate Alzheimer’s progression.
Biomarkers increased by up to 95% more in obese participants than in non-obese participants.
The study tracked 407 participants over five years with blood tests and brain imaging.
Initial findings suggested lower biomarker levels in obese individuals, but long-term progression contradicted that.
The research was presented at the Radiological Society of North America's annual meeting.

Researchers Redefine Obesity

Researchers at Mass General Brigham propose new obesity criteria that could classify 70% of U.S. adults as obese, up from 42.9%, in a study published in JAMA Network Open.
The criteria add waist and body fat measurements to BMI, revealing higher health risks for people previously deemed healthy.
Experts say fat distribution matters more than weight and that 80% of adults over 70 may meet obesity criteria.
