Prevention of type 2 diabetes
This is a nice review of a research study that showed that lifestyle changes can have a major impact in lowering risk of diabetes. The interesting note to this is that the authors used impaired glucose tolerance as a marker for risk of diabetes. The ironic thing about this is that impaired glucose tolerance is virtually unheard of in mainstream medicine, and yet lab values identifying insulin resistance can yield very clinically important information. And with this information lifestyle changes can be implemented to lower risk of diabetes.
