From the change in self-regulation, memory is inhibited, allowing individuals to suppress or ignore unwanted or outdated associations and thus help to filter information relevant to dietary goals from irrelevant information.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 Contínua (ETCC) is a neuromodulating tool in which a low-intensity electrical current is applied to the scalp to modulate neuronal activity.

change in desire to consume food.
Questionnaires of Intense Food Desires - Trait (QDIC-T) validated for Brazilian Portuguese. The higher the score, the greater the amount of food craving presented.The QDIC-T scale is done on a 6-point scale with scores ranging from 39 to 214 points.
Time frame: pre-intervention.

Time frame: post-intervention (immediately after the end of study participation).
change in the executive brain functions - working memory
Trial Making Test (A and B). Assessments with single measurements (measurement of time, in seconds, to perform the test). the measurement unit for evaluating the outcome of these tests will be the amount of errors presented and the execution time (in seconds). The shorter the time and fewer errors, the better the result.
Time frame: pre-intervention.
change in the executive brain functions - cognitive flexibility
Stroop Tests. Assessments with single measurements (measurement of time, in seconds, to perform the test). the measurement unit for evaluating the outcome of these tests will be the amount of errors presented and the execution time (in seconds). The shorter the time and fewer errors, the better the result.
Time frame: post-intervention (immediately after the end of study participation).
change in the final value of inflammation scores
inflammation markers (PCR in serum). The biochemical dosage of all elements will be in mg/L, higher values will represent a higher concentration, that is, a greater degree of inflammatory processes.

change in desire to consume food.
Questionnaires of Intense Food Desires - State (QDIC-E); validated for Brazilian Portuguese. QDIC-E is made up of a five-point scale, ranging from 15 to 75 points. The higher the score, the greater the amount of food craving presented.
