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

Positive side effects of mental health that surprised me:

  1. Clearer skin — inflammation reduction improved my rosacea
  2. Better sleep — weight loss resolved mild sleep apnea
  3. Improved libido — better body image + improved cardiovascular health
  4. Less joint pain — obvious mechanical benefit
  5. More energy — metabolic improvements across the board

Not everything about GLP-1 therapy is a struggle. There are genuinely wonderful changes too. ✨

One thing that is still open after Dr.PulmRoch’s answer:

Was that from a primary source or from a summary of one?

One year anniversary on mental health — reflections:

What I wish I'd known: the side effects are temporary, the benefits compound over time, protein is more important than I thought, and the mental health aspect needs as much attention as the physical.

What surprised me: how much my relationship with food changed, the cascade of health improvements beyond weight, and how supportive this community is.

What I'd do differently: start therapy earlier, prioritize resistance training from day 1, and stop comparing my progress to others. Everyone's journey is unique.

Closing the loop on my own question.

Update: I got the sleep and the intake sorted before deciding it was the drug, and most of the flatness went with them. Not all of it, and I am watching the rest.

Therapy insights from my mental health journey: my therapist introduced me to the concept of "identity updating" — the psychological work of becoming a new version of yourself.

Key realizations: I used food to manage emotions, I had internalized fatphobia that I'm still unpacking, my social identity was partly built around being "the big guy/girl," and learning to accept compliments is surprisingly hard when you've been invisible for years.

Physical transformation without emotional processing is unstable. Do both.
