MedicalResearch.com: What are the main findings of the study?
Answer: It has been known that weight loss diets may improve metabolic status, in parallel with reduction of body weight. We found that the beneficial of various weight loss diets, such as high-fat and low-fat diets, may be different for people carrying different genotype.
MedicalResearch.com: Were any of the findings unexpected?
Answer: For long time, it is thought that a diet may affect people uniformly. However, our findings show evidence that this may be not true.
MedicalResearch.com: What should clinicians and patients take away from your report?
Answer: When people consider to reduce body weight or improve their metabolic status, they would choose the appropriate method, for example various weight-loss diets, according to their genetic feature. It is time to think about change from one-size-fits-all diet intervention toward personalized manner, by referring to ‘individuality’ of human genome.
MedicalResearch.com: What recommendations do you have for future research as a result of this study?
Answer: I would suggest to perform more comprehensive evaluation, for instance using genome-wide approach, in multiple intervention trials.
