Based on average results from the published clinical trials of the treatments we prescribe. Individual results vary. This is context, not a promise.
How to read these numbers
Each figure is the average percentage of body weight lost in the medicine's largest published trial, with diet and activity support on top. Averages hide a spread: in SURMOUNT-1, around a third of people on the highest Mounjaro dose lost 25% or more, while some lost under 5%.
The projection uses your starting weight, because percentages translate differently at 80 kg and 140 kg.
