The aim of this study is to evaluate the periodic use of continuous glucose monitoring (CGM) with an AI camera and following diet education among non-insulin-treated type 2 diabetes patients.

The control group used self-monitoring blood glucose (SMBG) for two weeks with a manual food diary followed by diet education and repeated SMBG with a food diary three months later. Treatment 1 group used CGM (Freestyle Libre) for two weeks with an AI food camera followed by diet education, and repeated CGM for two weeks with an AI food camera three months later. Treatment 2 group used CGM for two weeks with an AI food camera followed by diet education without repeat three months later. Every group followed at 6 months for the final outcome. HbA1c at 6 months is the primary outcome.

4. Ages 18 - 80 years old

Exclusion Criteria:
