## How long does tirzepatide take to work for weight loss?

Most people start to lose weight within about 4 weeks of starting tirzepatide. The more noticeable weight loss usually happens over about 3 to 8 months, and many people keep seeing progress for up to a year.

Some people notice appetite changes in the first week, but the scale often moves a little more gradually. How quickly it works can depend on your dose, how slowly your dose is increased, your metabolism, and how consistent you are with weekly treatment and daily habits.
