### Question
List out full name of patients who have "Diabetic diet" in the description of the care plan.

### Hint
full name = first, last; Diabetic diet refers to careplans.DESCRIPTION = 'Diabetic diet';

### SQL
SELECT DISTINCT T2.first, T2.last FROM careplans AS T1 INNER JOIN patients AS T2 ON T1.PATIENT = T2.patient WHERE T1.DESCRIPTION = 'Diabetic diet'
