PORTIONS-4

The general goal of PORTIONS-4 is to deepen the knowledge on the factors associated with the failure of interventions focused on changing habits, particularly those related to food, and to seek attractive, easy to implement, sustainable and affordable solutions for the population.

Portion control is an essential factor in the correct approach to obesity. Adequate portion management management in the context of an overall behavioral intervention can lead not only to an improvement in the nutritional quality of per diem expenses, but also to the recognition of internal cues of satiety and triggers of uncontrolled eating. Moreover, managing portions well as part of balanced and appealing recipes that include local and seasonal foods can improve food appreciation while decreasing preparation time, cost, and waste, all of which can promote adherence to a healthy per diem expenses .

This project aims to optimize the process of implementing interventions, favoring adherence and thus the effectiveness of the intervention, through the combined use of tools and support techniques for ration control, previously optimized and tested at laboratory. It is also proposed to develop healthy recipes, in line with current nutritional recommendations, that are tasty, quick and easy to prepare, and increase attractiveness, sustainability and affordability.

Taking into account the difficulty in measuring spontaneous behaviors in the laboratory, the second goal of this project is to explore the applicability of neurophysiological analysis technologies (Electroencephalography - EEG) to identify possible brain patterns, which could explain the lack of adherence to dietary interventions, and to explore new methodologies of assessment of eating behavior in the natural context of the person (outside the laboratory).
