Trial Outcomes & Findings for Personalized Lifestyle Intervention and Weight Control (NCT NCT04079972)

NCT ID: NCT04079972

Last Updated: 2026-01-06

Results Overview

Change was calculated as the value at the later time point minus the value at baseline (i.e., value at about 5 months after randomization minus baseline, and value at study completion (\~17 months) minus baseline). Positive values represent increases from baseline, and negative values represent decreases.

Experimental: Disclosure of Obesity-related Genetic Risk With Tailored Lifestyle Recommendations
Participants received their obesity-related genetic test results, including variants in FTO (rs9939609), MC4R (rs17782313), and BDNF (rs6265), along with genotype-tailored lifestyle recommendations. The counseling materials encouraged risk-allele carriers to adopt healthier behaviors such as reducing fat intake, limiting snacking, and avoiding emotional eating. Personalized genetic results and recommendations were delivered at baseline through a user-friendly report.
Active Comparator: Disclosure of Non-Obesity-related Genetic Traits Only
Participants received genetic test results limited to non-obesity-related traits (e.g., beauty-related genes). They did not receive any obesity- or metabolism-related genetic information or tailored lifestyle recommendations. The full obesity-related genetic results were disclosed only after completion of the final follow-up.

PRIMARY outcome

Timeframe: About 5 months after randomization and at study completion (~17 months)

Population: number of started population differs from completed population

Change was calculated as the value at the later time point minus the value at baseline (i.e., value at about 5 months after randomization minus baseline, and value at study completion (\~17 months) minus baseline). Positive values represent increases from baseline, and negative values represent decreases.
