Sleep problems are associated with poor blood glucose control, but current diabetes self-management programs do not include sleep education. This study will randomize participants into two groups: one that receives sleep education and one that does not. The researchers expect both groups to experience reductions in blood glucose. The researchers hypothesize that individuals who receive sleep education as part of their diabetes self-management training will experience greater improvements in blood glucose control, as measured by hemoglobin A1c, compared to the control group.

Inclusion Criteria:

• Individuals with a diagnosis of type 2 diabetes who are patients at the Michigan State University (MSU) Endocrinology clinic,
• a diagnosis of overweight or obesity (Body Mass Index greater than or equal to 25.0 kg/m2),
• the most recent hemoglobin A1c value greater than or equal to 7.5%, and
• the ability to attend online program sessions.

Exclusion Criteria:

• significant psychiatric disorders,
• advanced medical conditions that require alterations to the MNT for DM2, e.g., advanced chronic kidney disease, and
• an inability to follow recommendations due to cognitive deficits.
