Study Overview In this study, 1791 military veterans with poorly controlled type 2 diabetes were randomly assigned to receive either standard or intensive glucose control Other cardiovascular risk factors were treated uniformly The glycated hemoglobin goal was an absolute reduction of 1.5 percentage points in the intensive- therapy group There was no significant difference between the two groups for the rates of major cardiovascular events, death, or microvascular complications

Study Overview This 2-year trial, which took place in an isolated workplace that facilitated retention in the study, randomly assigned 322 moderately obese subjects to one of three diets: a low-fat, restricted-calorie diet; a Mediterranean, restricted-calorie diet; or a low-carbohydrate, non-restricted-calorie diet The results suggest that the Mediterranean and low-carbohydrate diets are effective alternatives to low-fat diets and that personal preferences and metabolic considerations might inform individualized tailoring of dietary interventions

Changes in Biomarkers According to Diet Group and Presence or Absence of Type 2 Diabetes Shai I et al. N Engl J Med 2008;359:

Conclusion Mediterranean and low-carbohydrate diets may be effective alternatives to low-fat diets The more favorable effects on lipids (with the low-carbohydrate diet) and on glycemic control (with the Mediterranean diet) suggest that personal preferences and metabolic considerations might inform individualized tailoring of dietary interventions
