Admit it, it would be a dream to find out which foods make us lose weight and which ones make us fat in a peculiar way through a genetic test. But the DNA diet does not yet exist, in spite of those who propose it with a lot of genetic testing , and this study by the American Society for Nutrition shows that little is known about the relationship between DNA and individual nutrition, but above all that what is known It does NOT make a difference as we hoped.

A sample of nearly 700 people, some with the FTO genotype, a key marker for an increased risk of obesity, was divided into four groups: only one group was informed that they had this genotype and received a controlled diet based on these informations; another group had the same diet but were kept in the dark; the remaining groups followed a controlled diet that is not specific but dietary like those of the other groups. Result?

People who were told they had an FTO genotype lost more weight , but not people who didn’t know and who also followed the exact same diet for their genotype. What does this mean? That most likely the “awareness” factor and the fear of gaining more weight influenced the participants much more than the genetic side.
Scientists are therefore doubtful of the efficacy of a targeted diet compared to a standard dietary diet: the DNA diet is still far to come, but what is known does not create substantial differences in the dietary protocol to be followed, which must be based always on calorie restriction and healthy diet.
