This paper presents data for the estimation of obesity levels in individuals from the countries of Mexico, Peru and Colombia, based on their eating habits and physical condition. The data contains 17 attributes and 2111 records, the records are labeled with the class variable NObesity (Obesity Level), that allows classification of the data using the values of Insufficient Weight, Normal Weight, Overweight Level I, Overweight Level II, Obesity Type I, Obesity Type II and Obesity Type III. 77% of the data was generated synthetically using the Weka tool and the SMOTE filter, 23% of the data was collected directly from users through a web platform. This data can be used to generate intelligent computational tools to identify the obesity level of an individual and to build recommender systems that monitor obesity levels. For discussion and more information of the dataset creation, please refer to the full-length article "Obesity Level Estimation Software based on Decision Trees" (De-La-Hoz-Correa et al., 2019).

Obesity has become a global epidemic that has doubled since 1980, with serious consequences for health in children, teenagers and adults. Obesity is a problem has been growing steadily and that is why every day appear new studies involving children obesity, especially those looking for influence factors and how to predict emergence of the condition under these factors. In this study, authors applied the SEMMA data mining methodology, to select, explore and model the data set and then three methods were selected: Decision trees (J48), Bayesian networks (Naïve Bayes) and Logistic Regression (Simple Logistic), obtaining the best results with J48 based on the metrics: Precision, recall, TP Rate and FP Rate. Finally, a software was built to use and train the selected method, using the Weka library. The results confirmed the Decision Trees technique has the best precision rate (97.4%), improving results of previous studies with similar background.
