Critical Midlife Strategies to Prevent Age-Related Brain Decline: In this episode, Nutritionist Leyla Muedin “Weighs In” with a landmark study published in PNAS, highlighting the importance of a critical midlife window to prevent age-related brain decline. Conducted by scientists from Stony Brook University and other renowned institutions, the study reveals that brain aging follows a non-linear trajectory with key transition points starting as early as age 44. The research identifies neuronal insulin resistance and metabolic changes as primary drivers, suggesting dietary interventions like ketogenic diets during midlife can provide significant benefits. Leyla emphasizes the importance of early metabolic health monitoring and lifestyle changes to mitigate cognitive decline, addressing the growing concern of Alzheimer's and related neurodegenerative diseases.
