Mounjaro for Weight Loss: How It Works, Who It’s For & What to Expect

Medical weight loss has evolved rapidly in recent years, and Mounjaro® (tirzepatide) is one of the most talked-about advancements. Originally developed for diabetes management, it is now used under medical supervision to support effective and sustainable weight loss.

At Luna Clinic, we believe weight management is not just about appearance—it’s about long-term health, confidence, and wellbeing. Here’s what you should know before starting Mounjaro.

What Is Mounjaro?

Mounjaro is a once-weekly injectable medication that targets two important gut hormones involved in appetite regulation and metabolism:

• GLP-1 (Glucagon-Like Peptide-1)
• GIP (Glucose-Dependent Insulinotropic Polypeptide)

This dual-hormone mechanism is what differentiates Mounjaro from earlier weight-loss injections.

How Does Mounjaro Support Weight Loss?

Mounjaro works through several proven mechanisms:

1. Appetite Suppression
   Helps you feel full faster and stay full longer, reducing portion sizes and cravings.
2. Slower Gastric Emptying
   Food remains in the stomach longer, improving hunger control between meals.
3. Improved Insulin Sensitivity
   Supports healthier blood sugar regulation and reduces fat storage.
4. Reduced “Food Noise”
   Many patients report fewer urges for emotional or mindless eating.

The result is steady, sustainable weight loss, not crash dieting.

Who Is Mounjaro Suitable For?

Mounjaro may be suitable if you:

• Have BMI ≥ 27 with weight-related concerns
• Have BMI ≥ 30
• Struggle with stubborn weight despite diet and exercise
• Have insulin resistance, PCOS, or metabolic syndrome
• Prefer a medical, evidence-based weight loss approach

Not suitable for:

• Pregnant or breastfeeding women
• Individuals with a history of medullary thyroid cancer
• Certain gastrointestinal or endocrine conditions (medical assessment required)

A doctor consultation is mandatory before starting treatment.

What Results Can You Expect?

Results vary by individual, but commonly include:

• Appetite reduction within 1–2 weeks
• 5–10% weight loss within 3 months
• Up to 15–20% weight loss over 9–12 months with lifestyle support

The goal is fat loss—not muscle loss—supported by nutrition and lifestyle guidance.

What Is the Treatment Process Like?

• Once-weekly injection
• Simple and quick administration
• Gradual dose titration to minimise side effects
• Regular follow-ups to monitor safety and progress

Possible Side Effects

Most side effects are mild and temporary, especially during the early phase:

• Nausea
• Bloating
• Reduced appetite
• Mild constipation or diarrhoea

These usually improve as your body adapts.

Is Mounjaro a Quick Fix?

No—and that’s a positive thing.

Mounjaro works best when combined with:

• Healthy eating habits
• Protein-focused nutrition
• Strength and lifestyle optimisation
• Ongoing medical supervision

This approach supports long-term weight maintenance, not rebound weight gain.
