Methods: This will be a two-arm, triple-blinded, randomized controlled trial with 54 subjects with food craving assigned to either: 1) a 10-session treatment protocol of real taVNS, or 2) a 10-session treatment protocol of sham taVNS, besides qualitative electroencephalogram (qEEG) and heart rate variability (HRV). Participants will be evaluated for primary outcome measures (Food Craving Questionnaire - State [FCQ-S] and Food Craving Questionnaire - Trait [FCQ-T]) before and after intervention, with a follow-up visit of 30 days after the end of treatment. A comparison between sham and active groups will be performed in three occasions [baseline (T1), at the end of the stimulation protocol (T2) and 30 days after the last day of stimulation (T3)].
