Once-weekly subcutaneous semaglutide 2.4 mg produces significantly greater weight loss in adults without type 2 diabetes (mean -11.57%) compared to those with type 2 diabetes (mean -6.34%).
If you have Type 2 Diabetes, expect semaglutide 2.4 mg to work, but anticipate roughly half the weight loss percentage compared to someone without diabetes. This is due to metabolic factors like insulin resistance and 'glycemic buffering' (where improved blood sugar control reduces calorie loss through urine). Manage expectations by focusing on metabolic health benefits alongside weight metrics, as the drug remains clinically effective for both groups.
The observed difference in weight loss efficacy between the groups was clinically meaningful. While once-weekly semaglutide at 2.4 mg elicited significant weight loss in both populations, the magnitude of effect was notably greater in those without DM.
Why this rating
Based on a systematic review and meta-analysis of 10 RCTs with rigorous statistical synthesis (random-effects model).
