The mental-health dimension is under-measured in the trial literature and the reports here are consistent enough to take seriously.

...mental health should only be used alongside therapy...

I'd say therapy should be AVAILABLE to all GLP-1 patients, but requiring it as a precondition for treatment would create an access barrier.

Not everyone can afford therapy. Not everyone needs it. Some people do just fine with medication + lifestyle changes. But for those with emotional eating, body image issues, or disordered eating history, therapy is extremely valuable.

My recommendation: make mental health screening part of the initial assessment, offer therapy as a recommended adjunct, but don't gatekeep medication access behind it.

Following on from sophie_paris — and this may be the naive question:

How long did you give it before you decided it was working?

Before/after narrative for mental health — one year in:

Before (286 lbs): Winded climbing stairs, chronic back pain, pre-diabetic, on 3 medications, dreaded mirrors, avoided photos, social anxiety about my weight.

After (191 lbs): Run 3 miles regularly, pain-free, A1C normal, down to 1 medication, bought a swimsuit for the first time in a decade, actually enjoy being photographed.

Total weight lost: 71 lbs. Total life gained: immeasurable. This isn't just about weight — it's about reclaiming your identity.

OP back with an update, since a thread like this is useless without one.

Follow-up — I put something in the gap where food used to be rather than waiting for the gap to close on its own. That was the part nobody told me.

Body image adjustment with mental health: I've lost 92 lbs but when I look in the mirror, I still see my old self sometimes. "Phantom fat" is a real phenomenon.

My therapist specializes in body image issues with weight loss patients. She says it can take 12-18 months for your brain's body map to update. In the meantime: take progress photos (your eyes lie but cameras don't), try on old clothes, and be patient with yourself.
