First seen Jan 04, 2026 · Last updated May 22, 2026 · Updated 22 times
Summary
This study looked at how blood sugar levels, gut bacteria, and iron buildup in the brain are connected to thinking skills in people with obesity. Researchers followed 128 adults aged 30-65, some of whom lost weight through surgery or diet. They used glucose monitors, brain scans, cognitive tests, and activity trackers to gather data. The goal was to understand these relationships, not to test a treatment.
