Summary

This randomized clinical trial was carried out from January 2017 to December 2017 at the facilities of the Catholic University of Murcia. Written informed consent was required from each patient. The protocols of the present clinical trial follow the CONSORT standards. To measure the impact of cognitive training on weight loss in overweight / obese subjects, a double-blind study (de facto masking) was designed. Both the participants and the statistical assessors were unaware of the study hypothesis. Participants were unaware of treatments and possible assignments between groups, and only those subjects who were randomly assigned to the cognitive training group were informed that such training was part of dietary therapy. The principal investigator of the present study (J.J.H.M.) carried out the randomization, with the assistance of the Microsoft Excell program, with the help of a macro designed in Visual Basic® for that purpose. The randomization divided the subjects into two groups, as they were treated with a hypocaloric diet plus 12 nutrition education sessions (CONTROL group) or a group that were treated with a hypocaloric diet plus 12 sessions of cognitive training (COGNITIVE group). In order to obtain a similar size in both groups, a randomization in blocks with a 1: 1 allocation ratio was performed. Cognitive performance measures were performed before and after training. One week before the beginning of the cognitive and dietary intervention, the participants performed a series of cognitive tests. After 12 weeks of both dietary and cognitive intervention, participants were reexamined to measure performance on neurocognitive tests.

Interventions

Type	Name	Description
BEHAVIORAL	Cognitive Training	The intervention was carried out with the PC game Brain Exercise TM (Bandai Namco Games Ltd.). Participants held the training sessions on an HP 250 G3 Notebook PC (Windows 10), with a 15-inch screen, and a resolution of 1366x768x40 Hz. The performance achieved by each participant in each session was recorded to analyze the evolution of the subjects. The participants made a total of 12 practice exercises, which implies approximately 30 minutes of duration per session.
