Resting-state functional magnetic resonance imaging session. All participants were instructed to abstain from any food or drinks apart from water for at least 3 h before their visit to the laboratory. Approximately 30 min before the resting-state functional magnetic resonance imaging (rs-fMRI) scanning, each participant was instructed to consume pre-prepared snacks (280 kcal) to standardize their internal states of hunger and fullness. Approximately 10 min before the rs-fMRI scanning, participants rated their levels of hunger and fullness.
