Dietry and physical activity counselling in the prevention of type 2 diabetes

Type 2 diabetes, formerly known as non-insulin-dependent diabetes (NIDDM), constitutes a major portion (90-95%) of all cases of diabetes worldwide. The objective of this study was to evaluate and provide evidence on current published literature about diet and lifestyle in the prevention of type 2 diabetes and thereby making disease-specific recommendations. There is a convincing evidence for a decreased risk of type 2 diabetes in adults who are physically active and maintain their normal body mass index (BMI). Also an increased risk for developing type 2 diabetes is associated with overweight, obesity and physical inactivity.On the basis of available evidence regarding diet and lifestyle in the prevention of type 2 diabetes, it is recommended that a normal weight status in the lower BMI range (BMI 21–23) and regular physical activity be maintained throughout adulthood; abdominal obesity be prevented; and low intake of saturated fats be encouraged.
