These medications don't shrink a person without limit. Each one comes with a real ceiling, and there's a genuine dose-response pattern behind that. Seems like you saw a strong early drop and then plateaued. Regaining on ozempic tracks with a couple things. For one, it generally underperforms mounjaro across the broader population. Tons of people do well on it, and a smaller slice actually do better on ozempic specifically, but that's the exception rather than the rule. Switching over usually means a milder response for most. Beyond that, a fresh randomized trial found that 40% of people who scaled back to 5mg mounjaro to hold steady (down from 10 or 15) regained half of what they'd shed. A big chunk of people genuinely need the full protocol that got them there just to keep it off. Scaling back the dose, or switching over to ozempic, lines up pretty naturally with regaining then.
Were it me, I'd head back to mounjaro right away.
