Medications like Ozempic®, Wegovy®, and Mounjaro® have dominated headlines in recent years, hailed as game-changers in the treatment of obesity. As interest grows, so do questions — how do they work? Who are they for? And are they a “magic bullet” for weight loss?
At Zenvité, we take a balanced, evidence-based approach to weight management, including the use of GLP-1 medications where appropriate. Here’s what you need to know about these modern weight loss injections.
What Are GLP-1 Medications?
GLP-1 medications are a class of drugs that mimic the hormone glucagon-like peptide-1 (GLP-1), which helps regulate appetite and blood sugar.
They were originally developed for type 2 diabetes but have since been approved for weight management in people with obesity or overweight and certain health risks.
Common examples include:
🌱 Semaglutide (Ozempic® and Wegovy®)
🌱 Tirzepatide (Mounjaro® – which also targets a second hormone, GIP)
How Do They Work?
GLP-1 receptor agonists act on multiple systems to support weight loss:
✔ Reduce Appetite – they slow gastric emptying and act on brain centres to increase feelings of fullness and reduce cravings.
✔ Improve Blood Sugar Control – by stimulating insulin release and reducing glucagon secretion, they help stabilise glucose levels.
✔ Potential Cardiovascular Benefits – some studies suggest a reduction in cardiovascular events in high-risk patients.
Who Might Benefit From GLP-1 Medications?
GLP-1 medications may be considered if you:
🌱 Have a BMI ≥30 (obesity)
🌱 Have a BMI ≥27 (overweight) plus weight-related health issues such as type 2 diabetes, high blood pressure, or sleep apnoea
🌱 Have tried lifestyle interventions without sufficient success
They are not intended as a first-line treatment but as part of a broader weight management plan.
What to Expect With GLP-1 Treatment
Dosage and Administration
Administered as a once-weekly injection (self-administered with a pre-filled pen)
Dose typically titrated up gradually to minimise side effects
Weight Loss Outcomes
Clinical trials show average weight reductions of:
✔ 10–15% of body weight with semaglutide (Wegovy®)
✔ Up to 20% with tirzepatide (Mounjaro®)
Results vary and are most sustainable when combined with lifestyle changes.
Common Side Effects
Most are gastrointestinal and often improve over time:
🌱 Nausea
🌱 Diarrhoea or constipation
🌱 Heartburn
🌱 Rarely, more serious risks like pancreatitis or gallbladder issues
Addressing the Myths
“Is It a Quick Fix?”
No. While effective, these medications require ongoing use to maintain benefits. Stopping treatment often leads to weight regain if lifestyle habits haven’t changed.
“Does It Replace Diet and Exercise?”
No. GLP-1 medications work best as part of a comprehensive plan that includes nutrition, movement, sleep, and stress support.
