Weight loss medication calculator

Applies the average result from each medication's main trial to your starting weight. It is not a prediction of your result.

How to read this

• Results are averages across thousands of people. Many lost more and many lost less.
• The placebo comparison is people who got lifestyle support but not the drug.
• Trials lasted 56 to 72 weeks. Weight tends to return after stopping the medication.
• Most trials were funded by the drug's manufacturer. See the full comparison.
