The Genetics of Obesity, Part III

Genetics Loads the Gun, Environment Pulls the Trigger

Thanks to a WHS reader* in support of reminding me of the beyond citation by Dr. Francis Collins, director of the US National Institutes of Health**.  This is a model so as to help reconcile the following two seemingly contradictory observations:

1.     Roughly 70 percent of stoutness hazard is genetically inherited, leaving simply 30 percent of hazard to environmental factors such as diet and lifestyle.
2.     Diet and lifestyle allow a big force on stoutness hazard.  The prevalence of stoutness has tripled in the keep up 30 years, and the prevalence of extreme stoutness has increased by almost 10-fold.  This is presumably not an adequate amount of instant in support of genetic changes to story in support of it.
