"Predictive Models of the Morphological Evolution of the Human Body to Improve Adherence and Motivation in Dietetic-nutritional Treatments of Overweight and Obesity" [Modelos Predictivos de Evolución Corporal Para Mejorar la Adherencia en Tratamientos de Sobrepeso y Obesidad]

The objective of this clinical trial is to evaluate the effect of a personalized intervention based on the benefits of 4D body modeling and virtual reality techniques, combined with a dietary-nutritional treatment focused on the Mediterranean Diet, as a tool to improve motivation for change, adherence to treatment and health parameters in patients with overweight and obesity. The main research questions to be addressed are: * How can a 4D computer vision model combined with virtual reality improve clinical diagnoses, the analysis of morphological changes in the human body over time, and adherence to dietary-nutritional treatment? * Does adherence to an intensive multifactorial dietary-nutritional treatment based on the Mediterranean Diet (MD), supported by 4D immersive virtual reality technology, lead to improvements in cognitive functioning? * What impact does a nutritional intervention program based on the Mediterranean Diet and the use of virtual reality have on body image perception? * Can an intensive intervention based on the Mediterranean Diet and 4D virtual reality technology improve overall health? Researchers will compare the control group (which will receive nutritional recommendations based on the Mediterranean Diet) with the experimental group (which will receive nutritional recommendations based on the Mediterranean Diet and visualize their morphological changes through VR) to determine whether a personalized intervention based on the benefits of 4D modeling and virtual reality, combined with a Mediterranean Diet-focused treatment, is effective in addressing overweight and obesity. Participants are expected to: * Follow the dietary-nutritional recommendations throughout the 6-month intervention. * Visit the clinic once a month for follow-up. * Complete all clinical and psychological assessments.
