Diet and exercise regimen results `predictable`
Washington: It could be possible to predict whether a specific diet and exercise regimen would actually help you lose weight.
Scientists have identified five epigenetic biomarkers in adolescents that were associated with a better weight loss at the beginning of a weight loss program.
Not only could this could ultimately help predict an individual`s response to weight loss intervention, but it may offer therapeutic targets for enhancing a weight loss program`s effects.
"Successful obesity treatment during adolescence could reduce morbidity at later stages of life and lead to a better quality of life. It is crucial to find new markers for obesity treatment. Here, we describe five putative epigenetic biomarkers that could help to predict the response to a weight loss intervention in obese adolescents," said Amelia Marti, Ph.D., Pharm. D., co-author of this study from the Department of Nutrition, Food Science, Physiology and Toxicology at the University of Navarra in Pamplona, Spain.
To make this discovery, Marti and colleagues first performed a global methylation assay in 24 adolescents who had the best and worst response to the EVASYON weight loss program, and then expanded the sample to include 83 more adolescents.
Researchers measured an epigenetic marker, DNA methylation levels, in obese adolescents from a blood sample at baseline and again at the end of the 10-week program. Participants were then divided into two groups (high and low responders) according to the weight loss achieved.
The researchers found that the baseline DNA methylation levels of five epigenetic markers were associated with better weight loss response.
This EVASYON program is a lifestyle and nutritional educational weight loss program that includes a multidisciplinary team of nutritionists, physiotherapists, psychologists and pediatricians. EVASYON was conducted in five Spanish cities: Granada, Madrid, Pamplona, Santander and Zaragoza.
The research published in the June 2013 issue of The FASEB Journal.
