PEREZ-ORTIZ, Alejandro et al. Eating speed in people with normal-weight and overweight-obese: An experimental analysis. Rev. Mex. de trastor. aliment [online]. 2022, vol.12, n.1, pp.15-24.  Epub 10-Jun-2024. ISSN 2007-1523.  https://doi.org/10.22201/fesi.20071523e.2022.1.719.

Obesity has become one of the main public health problems in Mexico. Its study involves the analysis of eating behavior (EB) and some of its parameters, such as eating speed (ES). The objective of this study was to compare the ES, size and number of bites, number and pattern of chewing performed by normal-weight (n = 5) and overweight-obese (n = 4) individuals. Using a single-assessment quasi-experimental design, participants were videotaped while eating a slice of pizza (90 grams). Significant differences were found in bite size (Z = 2.357, p = 0.016) and number of bites (Z = -2.357, p = 0.016), with a small effect size in both parameters (r = 0.29), indicating that overweight-obese individuals have a larger bite size and take a smaller number of bites. Mexico has an obesogenic environment and a high prevalence of chronic degenerative diseases, which share EB as one of the main causes of their genesis; continuing with the study of ES and associated parameters will allow us to lay the foundations for the design of interventions for the prevention of overweight-obesity.
