Aim: The aim of the present research was to evaluate the effectiveness of a therapy package for weight control based on Acceptance and Commitment with the Matrix Approach and Transcranial Direct Current Stimulation (tDCS) on Food Craving and Physical Activity in overweight individuals. Methods: The research Design was a quasi- experimental with pretest and posttest and An Active Control group. For this purpose, 40 person were selected via availability sampling and in regard to include and exclude criteria. The instrument of the study were Baecke's Physical Activity Questionnaire (1982) and Food Craving Questionnaire-Trait of Cepeda- Benito (2000, FCQ-T). The experimental group received the intervention package in 12 online group sessions of 2-hour weekly sessions and 8 individual sessions of tDCS AR/CL stimulation(2Ma for 20 minutes) and the control group received only 8 individual tDCS sessions of AR/CL stimulation(2Ma for 20 minutes). Results: The results of between- within group mixed analysis of variance showed that the combined intervention package of weight control based on Acceptance and Commitment with the Matrix Approach and Transcranial Direct Current Stimulation (tDCS) had a significant effect on physical activity and cravings of overweight people in comparison with tDCS alone. Conclusion: According to the results, it can be concluded that the therapeutic package of the present study can be a good option to increase Physical Activity and reduce Food Craving.
