The paper identifies NTS-KLB glutamatergic neurons as critical for mediating FGF21's effects during dietary protein restriction, showing their role in metabolic and behavioral adaptations.

This study shows that FGF21 in the brain enhances the reward value of protein, increasing motivation to consume it during protein restriction.

This study shows that dietary protein restriction leads to persistent changes in protein preference and brain activity, suggesting long-term effects beyond immediate nutritional state.
