Inclusion Criteria: * Eligible participants (N=120; 60 Chinese Americans and 60 Vietnamese Americans) * Community-dwelling adults aged ≥ 18 with independent living; * Diagnosed with T2D; * Hb1Ac\>7.0% * Self-identified as first- or second-generation Chinese or Vietnamese immigrants; * Able to communicate in English, Chinese, or Vietnamese. We will focus on Mandarin-, Cantonese- or English-speaking Chinese Americans because the two best-known and most-spoken variants of Chinese are Mandarin and Cantonese, who use the same writing system; * Have a smartphone, iPad, tablet, or Apple watch Exclusion Criteria: * Taking hypoglycemia agents (e.g., insulin and sulfonylureas) with the major side effect of hypoglycemia that need close monitoring the occurrence of hypoglycemia to adjust/reduce medications to avoid future hypoglycemia. * Taking medications that impede weight loss (e.g., prednisone) within the last 3 months. * Currently pregnant, breastfeeding, or contemplating pregnancy within the next 6 months. * Have serious physical complications (e.g., severe neuropathy cardiovascular disease, COPD/emphysema, osteoarthritis, or stroke) or mental disease (e.g., schizophrenia, bipolar disorder, manic depressive illness, severe depression, or active substance abuse). * Have conditions that restrict diet, such as severe gastroparesis, ulcers, or food allergies. These conditions may need special dietary intervention. * Undergoing treatment for cancer, as cancer treatment may impact the outcome of glucose changes. * Have marked renal impairment (eGRF\<45; CKD-3b), as renal impairment may needs special dietary intervention and they also may impact glucose changes. * Are taking psychotropic medications that raise blood glucose (e.g., atypical antipsychotics). * Are prior or current CGM users including both Dexcom and FreeStyle Libre and plan to continuously use these CGMs in the next 6 months. * Are participating in another T2D intervention study.
