Protocol for evaluating protein intake-induced feeding inhibition in Drosophila using a pre-feeding approach.

Consumption of dietary protein has been shown to elicit the strongest satiety among macronutrients. Protein intake-induced feeding inhibition (PIFI) plays a critical role in the maintenance of nutrition homeostasis. Here, we present an optogenetic pre-feeding protocol for studying the neural mechanisms underlying PIFI in Drosophila.
