Ozempic Weight Loss Calculator
Estimate your results by month and starting weight
Use clinical-trial averages to estimate your weight loss on Ozempic (semaglutide) — both how it builds over time and roughly how many pounds that is for your starting weight. These are population averages, not a promise; your own result depends on dose, diet, activity, and individual response.
How to estimate your Ozempic weight loss
Weight loss on semaglutide builds gradually as you titrate up and your body responds — most of it comes over the first 6–12 months. To estimate your pounds lost, multiply your starting weight by the percentage figures below.
Ozempic (semaglutide, dosed up to 2 mg for type 2 diabetes) typically produces about 6–14% total weight loss in studies; the higher-dose 2.4 mg version (Wegovy) reaches roughly 15% at 68 weeks. Use the lower end if you are on a lower dose.
Typical weight-loss timeline (semaglutide averages)
| Time on treatment | Typical total weight loss |
|---|---|
| Month 1 | ~2–4%Best |
| Month 3 | ~5–7% |
| Month 6 | ~8–11% |
| Month 9 | ~11–13% |
| Month 12+ | ~12–15% (higher at 2.4 mg / Wegovy) |
Estimated pounds lost by starting weight
| Starting weight | At 10% loss | At 15% loss |
|---|---|---|
| 150 lb | 15 lb → 135 lb | 23 lb → 127 lbBest |
| 180 lb | 18 lb → 162 lb | 27 lb → 153 lb |
| 200 lb | 20 lb → 180 lb | 30 lb → 170 lb |
| 250 lb | 25 lb → 225 lb | 38 lb → 212 lb |
| 300 lb | 30 lb → 270 lb | 45 lb → 255 lb |
What changes your result — and safety
Dose, how long you stay on treatment, diet quality, protein intake, activity and resistance training, sleep, and individual biology all move your number up or down. People who reach and hold a higher maintenance dose, and who pair it with lifestyle changes, tend to land at the upper end.
These are estimates from trial averages, not medical advice or a guarantee. Your prescriber sets your dose and plan. Track your actual weekly weight in Shotlee to see your real curve instead of an average.
Frequently Asked Questions
On average, semaglutide produces about 6–14% total body weight loss for Ozempic (≤2 mg) and around 15% for Wegovy (2.4 mg) over roughly a year. For your pounds, multiply your starting weight by the percent — e.g. 200 lb × 10% = 20 lb. Individual results vary.
Most people see a few percent in the first month or two as they titrate up, around 5% by month 3, and the bulk of the loss over 6–12 months. Weight loss is gradual, not immediate.
Common reasons include still being on a low starting dose, early plateaus, diet, or individual response. The averages assume reaching a therapeutic dose over time. Tracking weight, dose, and food in Shotlee helps you and your prescriber spot what to adjust.
Both are semaglutide, but Wegovy goes up to 2.4 mg and reaches ~15% in trials, while Ozempic is dosed up to 2 mg with somewhat lower average weight loss. The higher dose generally means more weight loss.
