Early maturational emergence of adult-like emotional reactivity and anxiety after brief exposure to an obesogenic diet

This study shows that a short-term obesogenic diet during adolescence impairs fear extinction and increases anxiety-related molecular markers, while adult rats show heightened stress reactivity.

Developmental regulation of fear memories by an obesogenic high-saturated fat/high-sugar diet

This study shows that an obesogenic diet during adolescence impairs fear extinction learning and memory retention in rats, linked to reduced dopamine receptor D1 mRNA levels in the prefrontal cortex.
