Byetta 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 Byetta is approved for

Byetta weight-loss results
We do not publish a weight-loss trial figure for Byetta, because there isn't an honest one to publish: it was not studied as a weight-management drug and is not approved for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 Byetta side effects page.
