Why Am I Not Losing Weight on Mounjaro? (UK Guide)
If you’ve started Mounjaro and expected fast results, it can be frustrating when the scale doesn’t move. The reality is that several factors influence your progress.
Common reasons:
- Still on a starter dose (2.5mg)
- Low protein intake
- Hormonal resistance (menopause, PCOS)
- Hidden calories (snacks, alcohol)
- Not enough time (results often show after 6–10 weeks)
What to do:
- Optimise your dose
- Prioritise protein (80–100g/day)
- Hydrate properly
- Review lifestyle habits
👉 If progress stalls after 12 weeks, a personalised plan is key.
