GLP-1 Weight-Loss Estimator
This shows the average weight-loss range seen in the major clinical trials, applied to your starting weight — so you can picture what "15%" or "20%" actually means in pounds. It is an educational illustration of published averages, not a prediction of your personal results.
Average trial range for your weight
— lost on average
Read this carefully: these are average
results from clinical trials at the highest doses over roughly 68–72 weeks. Individual
results vary enormously — many people lose more, many lose less, and some
respond minimally. This is not a promise, a prediction, or medical advice. Your real
results depend on your body, dose, diet, activity, and how long you stay on treatment.
Talk to your prescriber about what's realistic for you.
Losing weight is the easy part — keeping your muscle is the work
Get the free GLP-1 Protein Checklist so more of what you lose is fat, not muscle — plus one practical, evidence-based email each week.
