Genetic obesity - Is Obesity Genetic or Environmental?
May 23rd, 2008, Posted in Obesity TreatmentThere is no such thing as “only genetic” or “only environmental” obesity. All organisms are both programmed genetically, and living in a particular environment. One cannot separate them in this way. Only if two people are put into the exact same environment and show different responses can one say that one is perhaps genetically predisposed to be different than the other. Each organism has a norm of reaction which specifies their possible response to a particular environment. Simply because one or more “obesity genes” have been located does not mean that humans who carry these will become definitively obese regardless of environmental intervention. It also does not mean that humans who do not express these genes cannot become obese.
