The goal of this clinical trial is to develop a "GlycoBite" snack bar formulation combination of red beans and tomatoes, and to assess its acceptability, nutritional content, and effectiveness on blood glucose levels in diabetic patients. The main questions it aims to answer are:

1. Dose snack bar formulation combination of red beans and tomatoes as a potensial healthy snack for diabetic patients?
2. Does snack bar formulation combination of red beans and tomatoes improve glycemic control
3. Does snack bar formulation combination of red beans and tomatoes lower blood glucose

Researchers will compare GlycoBite (red beans and tomato combine) snack bar to commercial snack bar to see if GlycoBite works to control blood glucose

Participants will:

1. Take 40 grams of GlycoBite or commercial snack bar every day for 3 weeks
2. Weekly fasting blood glucose monitoring and evaluations were carried out.
3. Monitoring glycemic control ( HbA1c Levels) before and after intervention.

Inclusion Criteria:

1. Type 2 DM patients
2. No medication therapy modifications during the intervention; and 4) no
