• The primary objective of this study is to evaluate the effect of a diet program including Glucerna SR as a meal replacement on postprandial glucose response after using Glucerna SR for 24 weeks in obese Asian subjects with type 2 diabetes [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
  

• evaluate the efficacy and safety of a meal replacement program with Glucerna SR vs. an EDP based on the nutrition therapy recommendations from the ADA on anthropometric measurements, lipid profile, meal-related metabolic changes and quality of life [ Time Frame: 24 weeks ] [ Designated as safety issue: Yes ]
  

A sufficient number of Asian subjects (expected to be approximately 90) with type 2 diabetes who have a BMI 18 between 25-40 kg/m2 and meet all the inclusion criteria and none of the exclusion criteria will be entered into the study to randomize approximately 60 subjects. The eligible obese subjects with type 2 diabetes will be entered into a 2-week lead-in period with EDP after individual diet/lifestyle consultation to implement nutrition therapy into their existing diabetes management. The diet recommendations of the EDP at the lead-in period will be based on the nutrition recommendations from the ADA including carbohydrate and monounsaturated fat together provided 60-70 % of energy intake, reduced intakes of saturated fat (< 10 % of total calories) and cholesterol (< 300 mg/day) and protein intake around 15-20 % of total daily energy.

Approximately 60 participants will be randomized at Week 0 (Visit 3) in a 1:1 ratio to receive either (1) a meal replacement program with Glucerna SR on top of the EDP or (2) an caloric-matched EDP only. The participants will receive an educational program of diet, exercise, and behavioral strategies at randomization. Each randomized subject in the meal replacement group will receive Glucerna SR to replace one meal (breakfast) and one pre-sleep snack for 24 weeks. The subjects in the group with EDP only will receive a meal plan like they have in the lead-in period. All study subjects will be placed on a diet plan with 500 ~ 800 kcal/day less than their estimated daily maintenance energy requirement and receive an individualized exercise prescription to facilitate an optimal diabetes management. The participants will visit the clinics at 4-week intervals for 24 weeks after randomization to evaluate the efficacy and the safety parameters. The participants will receive two different meal tests at both the baseline and the end of the study. The macronutrient composition in the meal test protocol 1 is a 480 Kcal Glucerna SR breakfast with 50 % CHO, 20 % protein, and 30 % fat. The test meal protocol 2 is a 480 Kcal sandwich breakfast with 63 % CHO, 20 % protein, and 17 % fat. The primary efficacy variable will be the change from baseline in incremental area under curve (∆AUC) of glucose response after a Glucerna-SR test meal between the two groups.

A telephone follow-up will be performed 2 weeks after the study to evaluate any condition related to the study.
