Already got the injection, but if you stop taking it afterward, it will still rebound.

You still need to control your diet and exercise regularly, and develop good habits.
As far as I remember, tirzepatide was originally used for diabetic patients. Its main function is to suppress appetite and change the body's metabolism.
But when the drug's effects wear off, the body will gradually return to its original metabolic state, causing appetite to rebound and calorie intake to increase. You need to maintain the original dietary habits.
However, if you rebound after stopping the medication and start using it again, it forms a cycle of "injection-stop medication-rebound-inject again," and the consequences of this can be very serious.
