> because without changing habits, if a patient stops using the drug, they'll regain the weight in a short time...

Not a short time, in whatever the time would normally be they would gain the weight if they continue on their prior habits, or in a less time if they only mildly improve their habits, and a lot longer time if they make significant changes, and not at all if they make dramatic changes.

So far, it has little to nothing to do with the drug. This line of argument always makes no sense to me, because whatever weight was lost with the drug, wasn't gained in that time. So you remove the weight lost, and the weight that would have been gained.

It's like setting yourself back to a starting line in a race. Yes, maybe you still run as fast, and will make it back to where you were, but it has nothing to do with the setting yourself back to the starting line.

It's such a weird line of thinking. It really makes no sense to me.

Since you might still keep running, we shouldn't bother setting you back at the starting line....

there's studied that say between 1 and 2 years, that sounds like short time to me.

One study looked at patients with obesity or overweight without diabetes who stopped taking tirzepatide 10 mg or 15 mg after taking it for 36 weeks. Patients who stopped taking tirzepatide experienced a 14% weight regain after 1 year.

However, there are not enough studies to draw scientific conclusions, but all evidence points to what I said.

As does the discussion in places like reddit by people doing it. If they change their habits, they don't gain weight back. If they only change them somewhat, it just happens more slowly.
