How this projection works

We take the average loss reported in SCALE Obesity and Prediabetes (3,731 adults with obesity or overweight, without diabetes) and fit a smooth curve that reaches it at week 56. Real progress is lumpier: early weeks include water, increases follow the dose steps, and individual results range widely around the average. Diet and activity changes were part of the trial for everyone, including placebo.
