NCT07450066

Brief Summary

This clinical trial aims to recruit a core cohort of adults with normal weight, overweight, and obesity, but without other metabolic alterations, to undergo a six-month nutritional intervention. The main objective is to compare a genotype- and phenotype-based nutrition approach with a traditional nutrition plan adjusted only to phenotype. To evaluate the effectiveness of each type of intervention, anthropometric measurements and nutritional assessments will be collected at baseline, three months, and six months. In addition, plasma samples will be obtained to analyze clinical and non-clinical biomarkers, providing a more comprehensive evaluation of health status at baseline and after six months of intervention.

Study Arms (2)

Control

ACTIVE COMPARATOR

Participants assigned to this arm (initially comprising 50 individuals) received nutritional counseling to promote adherence to a standard Mediterranean diet, based on general healthy eating guidelines for the Spanish adult population, along with phenotype-tailored recommendations for physical activity.

Other: Diet

Personalized Nutrition

EXPERIMENTAL

Participants in this arm were advised to follow a Mediterranean diet adapted through nutritional and physical activity recommendations tailored to their genetic profile, developed on the basis of a commercial nutrigenetic report.

Other: Diet

Interventions

DietOTHER

A six-month intervention consisting of lifestyle counseling aimed at promoting adherence to a standard Mediterranean diet and providing phenotype-tailored physical activity recommendations.
