What is tirzepatide for weight loss?

Tirzepatide (Zepbound brand) is a once-weekly injection used for weight loss, weight management. Tirzepatide works by reducing appetite, increasing the feeling of fullness, and slowing gastric emptying, which helps with weight loss.

Tirzepatide is self-administered as a subcutaneous injection using a pen (autoinjector) or syringe, and should always be used alongside a healthy diet and regular exercise.

How does tirzepatide work?

Tirzepatide is a GIP and GLP-1 receptor agonist and works like both of our natural hormones, GIP and GLP-1. Normally, when we eat, natural hormones called GIP and GLP-1 are released by the gut.

Tirzepatide works by suppressing appetite, slowing gastric emptying, increasing the feeling of fullness, and increasing insulin release and insulin sensitivity.

Tirzepatide works (mechanism of action) by activating both GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 (glucagon-like peptide-1) hormone receptors.

How much weight can I lose on tirzepatide?

Patients on tirzepatide (15mg) lost an average of 52 lbs  (22.5%) of their initial body weight over 72 weeks, compared to the placebo group, who lost an average of 5.3 lbs (2.4%) of their weight. These results were demonstrated in the clinical trial SURMOUNT-1 (NCT04184622). Individual results may vary.

Tirzepatide vs. semaglutide weight loss: SURMOUNT-5 Clinical Trial Results

Tirzepatide dual mechanism of action (GIP and GLP-1 receptor agonist) makes it significantly more effective than semaglutide for weight loss, which only activates GLP-1 receptors, as demonstrated in the head-to-head Surmount-5 clinical trial (NCT05822830), which reported an overall 47% greater weight loss with tirzepatide (Mounjaro, Zepbound) compared to semaglutide.

• Average weight loss: 50.3 lbs with tirzepatide vs. 33.1 lbs with semaglutide
• Average % Weight loss: 20.2% with tirzepatide vs.13.7% with semaglutid
• Waist size reduction: 7.2 inches with tirzepatide vs. 5.1 inches with semaglutide.

The Surmount-5 trial was a compared tirzepatide to semaglutide for weight loss over a 72-week treatment period at their maximum tolerated doses.
