Stopping Mounjaro: How to Avoid Weight Regain

Stopping Mounjaro: How to Avoid Weight Regain

Most people who stop Mounjaro (tirzepatide) regain a significant amount of the weight they lost, because appetite returns once the medication leaves the body. That doesn’t mean you have to stay on injections forever. With a plan in place before you stop, you can protect your results. This guide explains what happens when you stop, how much weight people typically regain, and the options consultant bariatric surgeon Mr Georgios Vasilikostas offers to help you keep the weight off.

What Happens When You Stop Mounjaro?

• Hunger returns. Tirzepatide reduces appetite and slows stomach emptying. Within weeks of stopping, most people notice hunger and cravings coming back.
• Portions increase. Without the medication, it becomes much easier to eat larger meals again.
• Weight comes back gradually. Your body’s natural drive is to return to its previous weight.
• Health benefits can reverse. Improvements in blood sugar, blood pressure and cholesterol may fade as weight returns.

Why People Stop Mounjaro

• The ongoing cost of long-term treatment
• Side effects such as nausea, reflux or constipation
• Weight loss has plateaued
• Planning a pregnancy (always discuss this with your doctor)
• Not wanting to take a weekly injection indefinitely

How to Stop Mounjaro Without Regaining Weight

1. Speak to your prescriber first. Don’t stop suddenly without medical advice; they may recommend a gradual approach.
2. Build habits while you are still on treatment. High-protein meals, portion control and regular strength training are easier to establish while your appetite is low.
3. Weigh yourself regularly. Agree a “trigger weight” with your clinician so that small gains are acted on early.
4. Get structured support. Dietitian and behavioural support improve long-term maintenance.
5. Consider a procedure to keep appetite in check. For many patients, this is the most reliable way to protect their results long term.

Procedures That Can Help You Keep the Weight Off

Unlike medication, a procedure keeps working without a weekly injection. Options at The GV Clinic include:

• Endoscopic Sleeve Gastroplasty (ESG): a non-surgical procedure that reduces stomach capacity by around 65–70% using stitches placed through the mouth. No incisions, usually home the same day, back to work in around three days. Suitable from BMI 30. Compare ESG vs Mounjaro.
• Gastric balloon: a temporary option to help control appetite while new habits become established.
• Gastric sleeve or gastric bypass: surgical options for people who still need significant weight loss, generally with a BMI of 40+, or 35+ with a condition such as type 2 diabetes.
• Combination therapy: a tailored plan that may combine a procedure with medication.
