Brief summary
The study aims to determine if genotype-based nutrition and lifestyle advice is effective for the management of overweight and obesity among Filipino adults compared to the usual standard of care.
Detailed description
The primary objective of the study is to determine if providing a nutrition and lifestyle advice with genetic information can promote the attainment of 5-10% weight loss, and improvements on body mass index, waist circumference, and body fat percentage among Filipino adults with overweight and obesity. Additionally, changes in dietary intake, eating behaviour, physical activity level, biochemical parameters (HbA1c and blood lipid profile), motivation for weight loss, and knowledge and perceptions on nutrigenomics and genetic testing will also be assessed.
Interventions
GENETICMyGeneMyDiet® Recommendations for Weight Management
This group will receive Nutrition and Lifestyle recommendation based on SNPs known to have an impact to body weight and body composition, and responses to physical activity and dietary fat intake
OTHERUsual Standard of Care for Weight Management
