From the change in self-regulation, memory is inhibited, allowing individuals to suppress or ignore unwanted or outdated associations and thus help to filter information relevant to dietary goals from irrelevant information. Provoking changes in neuroplasticity and cortical excitability contribute to the regulation of neural activity. Both could be modified by applying direct electrical current to the sensorimotor cortex, with polarity/current-dependent results, and their effect would last for hours after the end of stimulation. Transcranial Direct Current Stimulation (tDCS), translated into Portuguese as Estimulação Transcraniana por Corrente ContÃnua (ETCC) is a neuromodulating tool in which a low-intensity electrical current is applied to the scalp to modulate neuronal activity.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| tDCS + speech therapy+ sham | Experimental | Participants will receive real tDCS and tDCS sham for 5 sessions during each treatment period. The interstice period of the total intervention will be 25 days, with 15 days of wash out between the two interventions. The probabilistic, simple randomized sample will consist of participants with food cravings randomized into two groups, according to the presence or absence of changes in eating behavior and within each group there will be subdivision to receive or not neuromodulation, according to the flowchart |

The study will be a randomized, double-blind, parallel clinical trial. Participants will receive real tDCS or tDCS sham for 10 sessions during the treatment period. The interstice period of the total intervention will be 15 days (2 subsequent weeks, 10 working days, to apply the intervention). The probabilistic, simple randomized sample will consist of participants with randomized food cravings into two groups, there will be subdivision to receive or not neuromodulation, according to the flowchart.
