People with diabetes should receive nutrition counselling by a registered dietitian. Nutrition therapy can reduce glycated hemoglobin (A1C) by 1.0% to 2.0% and, when used with other components of diabetes care, can further improve clinical and metabolic outcomes. Reduced caloric intake to achieve and maintain a healthier body weight should be a treatment goal for people with diabetes who are overweight or obese. The macronutrient distribution is flexible within recommended ranges and will depend on individual treatment goals and preferences. Replacing high glycemic index carbohydrates with low glycemic index carbohydrates in mixed meals has a clinically significant benefit for glycemic control in people with type 1 and type 2 diabetes. Intensive lifestyle interventions in people with type 2 diabetes can produce improvements in weight management, fitness, glycemic control and cardiovascular risk factors. A variety of dietary patterns and specific foods have been shown to be of benefit in people with type 2 diabetes. Consistency in carbohydrate intake and in spacing and regularity in meal consumption may help control blood glucose and weight. Energy As an estimated 80% to 90% of people with type 2 diabetes are overweight or obese, strategies that include energy restriction to achieve weight loss are a primary consideration (26). A modest weight loss of 5% to 10% of initial body weight can substantially improve insulin sensitivity, glycemic control, hypertension and Contents lists available at SciVerse ScienceDirect Canadian Journal of Diabetes j o u r n a l h o m e p a g e : w w w. c a n a d ia n j o u r n a l o f d i a b e t e s. c o m

Resistance training, alone or in combination with aerobic training, may provide psychological benefits in adolescents with overweight or obesity, and therefore could be an alternative to aerobic training for some individuals in the biological and psychological management of adolescent obesity.
