Key Points

What is Mounjaro?

Mounjaro (tirzepatide), is an FDA-approved injectable medication for type 2 diabetes. It is prescribed in combination with diet and exercise to improve blood sugar control. While not officially a weight loss drug, weight loss is a common side effect. In clinical trials, participants lost up to 7.8 kg (17.1 lb) over 40 weeks.

How Much Weight Do You Gain Back After Stopping Mounjaro?

Many users wonder, “Do you regain weight after stopping Mounjaro?” There is limited research on weight regain after stopping Mounjaro for type 2 diabetes. However, a study on tirzepatide (the active ingredient) in adults without diabetes found that participants regained about 14% of their lost weight within a year after stopping treatment. This was an average weight gain of 11.1 kg (24.5 lb).

Why Do People Gain Weight After Stopping Mounjaro?

While on Mounjaro, the medication suppresses appetite by mimicking natural hormones (GLP-1 and GIP) that promote satiety and reduce food cravings. Once Mounjaro is stopped, hormone levels return to baseline, leading to the return of previous hunger signals. This is why gaining weight after stopping Mounjaro is common, especially if lifestyle changes aren't well established.
