How these projections are calculated
Projections use weekly weight-loss rates derived from clinical trial data (STEP and SURMOUNT trials) applied as a percentage of current body weight. Conservative reflects the 25th percentile of trial outcomes; typical reflects the median; best case reflects approximately the 75th percentile. Exercise multipliers reflect real-world data showing resistance training improves body composition outcomes by 8–22% compared to medication alone.
Weight loss is not linear — expect faster loss early and gradual slowing as you approach goal weight. Plateaus of 4–6 weeks are normal. These projections assume consistent adherence and do not account for dose titration delays or side-effect-related dose holds.
