How Much Weight Can You Lose on Mounjaro?

Clinical studies show that Mounjaro (tirzepatide) can help adults lose an average of 16% to 22.5% of their body weight over 72 weeks when used under medical supervision alongside lifestyle changes. This makes it one of the most effective prescription weight-loss medications currently available. In Malaysia, access to Mounjaro for weight loss must always be through licensed medical providers such as OVA Malaysia, with proper screening, prescription, and monitoring.

Key Takeaways

• Average weight loss with Mounjaro ranges from 16% to 22.5% of body weight

• Results depend on dose, duration, and metabolic health

• Most weight loss occurs progressively over 3 to 18 months

• Mounjaro supports weight loss by reducing appetite and improving insulin sensitivity

• Malaysians should only use Mounjaro through licensed providers such as OVA Malaysia

What Do Clinical Studies Show About Weight Loss on Mounjaro?

The largest weight-loss study on tirzepatide is the SURMOUNT-1 trial, published in The New England Journal of Medicine.

Key findings from the trial show dose-dependent weight reduction over 72 weeks:

• 16% average weight loss with 5 mg

• 21.4% average weight loss with 10 mg

• 22.5% average weight loss with 15 mg

For example, a person weighing 90 kg could lose approximately 14–20 kg with proper medical supervision and adherence. These outcomes substantially exceed typical results achieved through lifestyle changes alone.

In Malaysia, accessing Mounjaro safely for weight loss is best done through licensed telehealth providers such as OVA Malaysia, which offer professional screening, prescription management, and ongoing monitoring to ensure effective and safe treatment.

How Fast Do You Lose Weight on Mounjaro?

First 4–8 Weeks

Early weight loss is usually modest and driven by:

• Appetite reduction

• Smaller portion sizes

• Reduced snacking

Typical loss: 2–5% of body weight

3–6 Months

This is when fat loss becomes more visible:

• Clothes fit looser

• Waist circumference reduces

• Blood sugar improves

Typical loss: 8–15% of body weight

12–18 Months

Peak clinical results are usually reached here:

• 16–22.5% total body-weight loss

• Better metabolic health

• Easier long-term weight maintenance

Why Mounjaro Produces Greater Weight Loss Than Older Injections

Mounjaro works on two hormone pathways (GLP-1 + GIP), which:

• Strongly suppress appetite

• Slow gastric emptying

• Improve insulin sensitivity

• Reduce fat storage signals

By comparison, Ozempic activates only GLP-1. While Ozempic also supports weight loss, clinical trials consistently show greater average weight reduction with Mounjaro.

For Malaysians, both medications should be used under licensed medical supervision. Telehealth providers such as OVA Malaysia can facilitate doctor consultations, prescription management, and ongoing monitoring to ensure safe and effective use.

Who Tends to Lose the Most Weight on Mounjaro?

Weight-loss response is strongest in individuals who:

• Have higher starting BMI

• Have insulin resistance or type 2 diabetes

• Follow protein-focused nutrition

• Perform regular strength training

• Remain on treatment for 6–12 months or longer

Those who stop treatment early or skip medical follow-ups typically experience slower results or weight regain.

Is the Weight Loss From Mounjaro Sustainable?

Yes, when used correctly.

Sustainability depends on:

• Ongoing appetite control

• Muscle preservation through resistance training

• Gradual dose titration

• Continuous medical monitoring

Stopping Mounjaro suddenly without changing lifestyle habits often leads to rebound appetite and weight regain, which is why doctor-guided programs such as those offered by OVA Malaysia are essential for long-term success.
