Is the Carbohydrate-Insulin Model Dead? The Rumors Have Been Exaggerated
Dr. David Ludwig

Do the people whose defended body weight is measured today represent the same demographic as those whose DBW was measured in the past? If there have been changes in who ends up being weighed for research, there might not be a phenomenon. There might be more clinics in places where poverty and obesity go hand in hand than there were in the past, or more financial support for those who formerly couldn’t afford travel to a clinic, or deeper reach of solicitations for research subjects, courtesy of the internet and satellite TV.

Is the possibility that who is being weighed has changed, rather than human biology, considered in studies that find defended body weight on the rise?
