Clinical perspective, offered as context rather than as advice.

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.

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

How would you tell the difference between that and the alternative explanation?

When to call your doctor about mental health side effects — a reference I wish I'd had:

Call immediately:

  • Severe abdominal pain (could be pancreatitis)
  • Vision changes (thyroid concern)
  • Lump in neck (thyroid nodule)
  • Severe vomiting/can't keep fluids down for 24h+

Schedule an appointment:

  • Persistent nausea beyond 4 weeks
  • Significant hair loss
  • Mood changes or depression
  • Gallbladder symptoms (RUQ pain after eating)

Right, and the exception is worth naming rather than left implied, because the exception is where people get into trouble.

Moderator note: reminder that nothing in this thread is medical advice, and that clinical claims need a source. Tagging this one for the weekly digest.
