Objective:
To review evidence from literature on type 2 diabetes pertinent to physical activity and diet and lifestyle modification, and to determine the relevance of this evidence to clinical practice.
Quality Of Evidence:
Direct (level I) evidence supports interventions for physical activity and diet modification for primary prevention and management of type 2 diabetes. Few studies examine the effectiveness of primary health care providers' making such interventions.
Main Message:
Family physicians have an important role in identifying people at risk of developing type 2 diabetes and managing those diagnosed with the disease, yet they struggle to deliver practice-based interventions that promote sustainable behaviour change among their patients.
Conclusion:
It is evident that supporting patients to make changes in their physical activity and dietary habits can prevent onset of type 2 diabetes. Translating this finding into effective recommendations for clinical practice requires further effort and evaluation.
