How much weight can you expect on GLP-1?
Direct answer: trial averages vary by drug and dose — semaglutide trials report ~12–17% average loss at 68 weeks; tirzepatide trials report higher averages. This tool linearizes those percentages to provide a short-term projection.
Why individual results vary
Direct answer: baseline BMI, adherence, dose escalation, diet composition, and physical activity all shape outcomes. Use projections as a rough guide, not a promise.
Where the numbers come from
Representative sources: STEP trials for semaglutide and SURMOUNT trials for tirzepatide. These are averages — your mileage will vary.
