Treatments and medicines
Mounjaro before and after: what to expect month by month, according to the trials
Mounjaro can start to show weight loss within the first few weeks, but the first month usually coincides with the 2.5 mg starting dose and is a long way from the final result. Trials and clinical practice point to a gradual trajectory: early changes, further loss at 3 and 6 months and a greater average as you approach the one-year mark, with considerable variation from person to person.
