Genes and obesity

Very interesting interview Eroski Consumer has made Paul Castan, Scientific Director of Genotest, the company that sells Nutricheck, the test that identifies some of your genetic patterns of response to diet. I copy-hit some particularly juicy pieces:

(...) After the Human Genome Project, has been that the body's response to energy consumption, through certain foods that make you fat or thin, and metabolism by 30% depend on what is genetically programmed. The remaining 70% depends on a multifactorial environmental component. Through the sequencing of the human genome has been observed that housekeeping genes (housekeeping, in English) are responsible for the basal metabolism, that is, responsible for maintaining the body (hence the analogy with the maintenance of the house) . Through various studies and meta intervention, it was found that the genetic component is 30%. Furthermore, this percentage is accepted by the Food and Drug Administration (FDA)

(...) Some genes are directly responsible for the fattening food is assimilated; others relate to the nervous system and make after intake, one is left very satisfied with the food or, on the contrary, they are always hungry. This is because there are certain polymorphic variants that make the transmission of impulses satiety less effective. And there are others that have to do with the response of motility (gut action that moves the contents of the mouth to the anus) to certain substances.

Nutricheck is a test that provides sequence variants in the genes of every person. The goal is to see what best fits nutrition genetics of each individual, what foods are metabolized better and worse, what foods cause satiety volume from the legacy of each and if there is any disturbance in satiety , genetically based.

Probably soon enough become a test of this kind to know in great detail what our ideal diet. This is science.
