title: Effect of Caloric Intake 25 or 30 kcal/kg/day on the Glycemic Control in Obese Patients With Type 2 Diabetes.
abstract: BACKGROUND
  The recommended total dietary energy intake prescribed medical nutrition therapy for obese or overweight patients with type 2 diabetes in Japan is often set at 25 kcal/kg ideal body weight (IBW)/day. This study was conducted to determine the impact of the total dietary energy intake (25 or 30 kcal/kg IBW/day) on the glycemic control, lipid profile, and satisfaction level in overweight patients with type 2 diabetes.
  
  
  METHODS
  We performed interview and a designed prospective, randomized, controlled, multicenter study trial. Recruitment for interview for doctors and hospitalization of the obese or overweight patients with type 2 diabetes began from September 2008 and continued until June 2010. The subjects were randomly assigned to 25 kcal/kg IBW/day group (25 kcal group) or 30 kcal/kg IBW/day group (30 kcal group). The primary endpoint was the body weight of the subjects at the time of hospitalization, at the time of discharge from the hospital, and at 3, 6 and 12 months after discharge from the hospital.
  
  
  RESULTS
  The glycemic control, lipid control and body weight were similar between the 25 and 30 kcal groups during the 12-month follow-up, and the degree of satisfaction in respect of the medical treatment was significantly higher in the 30 kcal group than in the 25 kcal group at 1 year after discharge.
  
  
  CONCLUSIONS
  It is considered to be preferable for the caloric intake to be set at 30kcal/kg IBW/day rather than at 25 kcal/kg IBW/day for obese or overweight patients with type 2 diabetes.
