Background: Type II diabetes mellitus (DM) is a chronic metabolic disease characterized by hyperglycemia due to impaired insulin secretion or resistance. Nutrition education plays an important role in regulating diet and controlling blood glucose levels. Objective: This study aims to determine the effect of nutrition education on Blood Glucose Levels (GDS) and macronutrient intake in patients with type II diabetes mellitus. Methods: The study used a quasi experiment design with a non-equivalent control group pretest-posttest design. A total of 30 respondents were divided into two groups: 4-week nutrition education and no education controls. Data was collected through periodic blood glucose checks, and 24-hour food recalls.Results: Nutrition education had no significant effect on blood glucose levels during (p=0.701). However, there was a significant effect on changes in carbohydrate intake (p=0.002), while energy intake (p=0.133), protein (p=0.735), and fat (p=0.066) showed no significant change. Conclusion: Nutrition education does not have a significant effect on reducing blood glucose levels at any time, but it has a significant effect on increasing carbohydrate intake, although it is not optimal for energy, protein, and fat.
