First seen Jun 27, 2026 · Last updated Sep 10, 2026 · Updated 3 times
Summary
This study tested a 12-week diet and exercise program in 40 older adults with insulin resistance and apathy, a motivation disorder. Participants received all meals and supervised exercise. The goal was to see if the program improves insulin sensitivity and reduces apathy, and whether adding soybean to the diet boosts the effect.
