The take home messages from the presented prevention studies are:

bulletType 1 diabetes:  too early, more research required.
bulletType 2 diabetes:  Listen to your grandmother.  True improvement in diet and exercise habits (associated with weight loss) does at least delay, and may actually decrease the incidence of diabetes in at risk individuals. 


bulletYou should discuss with your diabetic patients the risk for diabetes in their siblings and offspring.  You should point out that their relatives should be given counseling about their risk for diabetes and the interventions that may limit this risk.
