This study is for Black adults with type 2 diabetes, which is a condition where the body has trouble using sugar for energy. The study is testing if a program called GEM can help. GEM involves coaching to eat less carbohydrates (sugars and starches) and exercise more after meals. A special device called a continuous glucose monitor (CGM) will be used to provide feedback on blood sugar levels.

The study aims to see if GEM can improve blood sugar control, decrease diabetes-related stress, and boost confidence in managing diabetes. Participants should not be using insulin or medications that make it hard to lose weight. Pregnant women or those planning to get pregnant soon cannot join.

• The study does not involve any medication treatments.
• Participants will receive coaching and use a CGM device.
• The study is designed to be safe, with no significant risks reported.
