What's the actual risk of losing too much weight when combining a stimulant and a GLP-1 medication?

Combining two medications that both commonly suppress appetite raises a legitimate practical concern about excessive or too-rapid weight loss and inadequate nutrition, more than it represents a specific studied "combined risk" figure, since dedicated research on this exact combination is limited. It's part of why providers managing both medications typically want to know about the other prescription, so they can monitor weight trend and nutrition more closely than they might with either medication alone.
