Abstract
The purpose of this paper is to introduce an Evolutionary Recommender System focused on promoting a healthy lifestyle through suggestions that jointly consider meals and physical activities, based on users’ aims and their preferences. Our solution considers a Genetic Algorithm as the main driver of the recommendation process. An experimental study of algorithmic performance is conducted on users with different goals, along with a cohort study to analyse how real users perceive the recommendations suggested to them. © 2019 Copyright for the individual papers remains with the authors.
