Summary: the purpose of this study is to find out if learning about healthy eating can help people with diabetes control their blood sugar better. this study is for men and women between 18 and 70 years old who use insulin at least twice a day but still have high blood sugar. we want to answer the following questions: can nutrition education help lower hba1c (a blood test that shows average blood sugar over the past 3 months)? can it improve knowledge about nutrition, quality of life, and make blood sugar more stable? will it help reduce fasting blood sugar, lipid levels, body weight, and the number of times low blood sugar (hypoglycemia) happens? participants will be divided into two groups: one group will receive a nutrition booklet. the other group will receive the same booklet and join four monthly lessons with a researcher. the four lessons will talk about: goals for managing diabetes main nutrients in food how to plan meals how to eat in a way that supports better blood sugar control

this study will involve 115 people with diabetes who need to take insulin at least twice a day. it includes those who already use multiple insulin injections but still have high blood sugar, and those who are newly switched to at least two insulin shots daily because their blood sugar is not well controlled with pills or pills plus one injection. the study will take place at cho ray hospital in ho chi minh city, vietnam, and will run from 2025 to the end of 2026. people will be invited to join at the endocrinology consultation unit. if they agree, their phone number will be collected and the research team will call them later to explain more about the study. if they are still interested, they'll be asked to keep a food diary for three days before their screening. on the screening day, they'll sign a short consent form, get blood tests to check their sugar, hba1c, cholesterol, and kidney function, talk with a nutrition researcher about their food diary, and have a usual consultation with their doctor. if they meet all the criteria and agree to take part, they'll sign the full consent form and take short tests on nutrition knowledge and quality of life. the quality of life questionnaire used is the sf-36 questionnaire, and nutrition knowledge is assessed using the diabetes-related nutrition knowledge questionnaire (drnk-q). after that, they will be randomly assigned to one of two groups. one group will get a nutrition booklet only. the other group will receive the booklet plus attend four monthly sessions with a researcher to learn about healthy eating for diabetes. in each group, 10 participants will also wear a flash glucose monitor (a small device that checks sugar levels without finger pricks) three times: at the beginning, after 3 months, and after 6 months. these participants will be selected based on age, hba1c level, ability to use the device, and whether they often experience low blood sugar. during the 6-month study period, all participants will have blood tests every 3 months to check hba1c, fasting sugar, and lipid; they will be asked monthly about any low blood sugar episodes; they will repeat the nutrition and quality of life tests at 6 months; their weight and waist size will be measured every 3 months, and their height will be measured at the start of the study
