A USC interview ask hit while my weight loss stalled

I got an email this week from a USC grad student looking for U.S. women 21–40 on GLP-1s for an online interview. I'm 34, almost 14 months in, and the last nine weeks have been a slog: same 4-pound window, same 6 a.m. protein shake, same 20-minute lunch walk. I want to say yes because I remember how little I knew at the start. But I'm also tired of describing this as a before-and-after when my graph is basically a bored squiggle right now. The questions are supposed to be about access, side effects, and daily life, not just pounds, which makes me more willing. Still, I'm wondering if I'll get weirdly defensive talking about the stall. Has anyone else done one of these interviews? Did it feel useful or just like unpaid emotional labor?
