About

The aim of this study is to evaluate the effect of premeal protein-enriched bar in long-term glycemic control in patients with type 2 diabetes mellitus. Glucose levels in subjects who intake premeal protein-enriched bar with dietary modification will be compared to those in subjects who only do the dietary modification.

Full description

Forty subjects with type 2 diabetes will be recruited. Every subject will be randomized in two groups, which are premeal protein bar with dietary modification group and dietary modification only group. The study will be conducted for 12 weeks for each participants. All participants will receive diabetes diet education. Intervention group will consume protein-enriched bar before each meals (at least twice a day) and control group will follow diabetes diet education without other additional supplements. Primary outcome is change of HbA1c from baseline for 12 weeks, and secondary outcomes are changes of fasting blood glucose level, body weight, waist circumference, blood lipid level, HOMA-IR and HOMA-beta from baseline for 12 weeks.
