There is a negative correlation between glycemic control (HbA1c reduction) and body weight reduction at the between-study level in all participants, but a positive correlation exists when analyzing patients with diabetes or non-diabetic participants separately.

For people with diabetes, GLP-1 RAs tend to improve both blood sugar and weight loss together. For non-diabetic individuals, these drugs still cause weight loss, but this may not translate to improved blood sugar markers since their levels are already normal. The relationship between weight loss and glycemic control is complex and depends on your starting health status.

The standardized pooled correlation coefficient between HbA1c levels and body weight was -0.42. A negative correlation between glycemic control and weight reduction was obtained.
