Mounjaro has no pivotal weight-loss trial behind it — it is not FDA-approved for weight management, and any weight change seen with it was a secondary observation in trials designed for blood-sugar control. If weight loss is the goal, the medications approved for it are the ones to compare.
What Mounjaro is approved for
Blood sugar control in adults and children 10 and older with type 2 diabetes, and lowering the risk of heart attack, stroke and cardiovascular death in adults with type 2 diabetes at high risk of them. It is not approved for weight loss; Zepbound is the same medicine approved for that.
Mounjaro weight-loss results
We do not publish a weight-loss trial figure for Mounjaro, because there isn't an honest one to publish: it was not studied as a weight-management drug and is not approved for that use. See the FDA label for the trials that supported its approved indication.
Why results vary, what happens after stopping, and how GLP-1 medicines compare with other approaches are covered once for the whole class in GLP-1 weight-loss results. Side effects that make people stop early are on the Mounjaro side effects page.
