MyGeneMyDiet Trial for Weight Management

Interventions Using Genomics-based Strategies (InGeSt) Towards Enhanced Nutrition Recommendations: A Proof-of-concept RCT for the DNA-based Nutrition and Lifestyle Recommendations in Overweight and Obese Filipino Adults

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.

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.

• Normal thyroid hormone levels in the blood
• Normal blood cortisol level
• Carriers of at least one of the risk alleles of FTO rs9939609, UCP1 rs1800592, and TCF7L2 rs7903146
