Mounjaro
If you’re considering Mounjaro (tirzepatide) for weight loss, one question is probably on your mind:
“How much weight can I actually lose?”
The honest answer is — a lot more than you might expect.
Unlike traditional diets or over-the-counter supplements, Mounjaro has been proven in clinical trials and real-world use to deliver substantial, lasting fat loss — often over 20% of body weight within a year.
At PPRX Online Pharmacy, we provide genuine UK Mounjaro pens, prescribed and dispensed by licensed healthcare professionals, helping people across the UK achieve safe, medically guided weight loss.
What Is Mounjaro and How Does It Work?
Mounjaro is a once-weekly injection that contains tirzepatide, a dual-action weight-loss medicine that mimics two powerful hormones:
- GLP-1 (Glucagon-Like Peptide-1)
- GIP (Glucose-Dependent Insulinotropic Polypeptide)
Together, these hormones:
- Reduce appetite and cravings
- Slow digestion so you feel full longer
- Improve insulin sensitivity
- Help your body burn stored fat for energy
Unlike calorie-restrictive diets that force willpower, Mounjaro works on the root cause of weight gain — hormonal imbalance and appetite dysregulation.
How Much Weight Can You Lose? (Realistic Results)
Results vary based on your starting weight, dose, and lifestyle, but both clinical studies and PPRX patient data show impressive outcomes.
1. Clinical Trial Results
In global studies published by Eli Lilly (SURMOUNT-1 and SURMOUNT-2):
- Average weight loss after 9 months: 15–20% of body weight
- Average after 12 months: 21–22%
- Some participants lost more than 25%
That means if you start at 90 kg, you could lose up to 18–20 kg (around 3 stone) within a year under proper supervision.
2. Real PPRX UK Patient Results (2025 Data)
Our UK patients report the following average progress:
| Duration | Typical Weight Loss | Experience |
|---|---|---|
| 1 month | 2–4 kg | Appetite reduction, smaller portions |
| 2 months | 5–8 kg | Noticeable drop in waist size |
| 3 months | 8–12 kg | Clothes fit better, visible transformation |
| 6 months | 12–18 kg | Steady fat loss, energy boost |
| 12 months | 18–22 kg | Long-term maintenance achieved |
These results are consistent across men and women, including patients with PCOS, prediabetes, or insulin resistance.
How Fast Will You See Results?
You’ll likely notice appetite changes within the first 1–2 weeks, followed by steady weight loss starting around week 3 or 4.
Here’s what the average journey looks like:
Weeks 1–4:
Your appetite decreases, you feel full quicker, and cravings fade.
Weeks 5–8:
Visible weight loss begins — most people lose 4–6 kg by this point.
Weeks 9–12:
Body fat continues to drop, especially around the stomach, arms, and face.
3–6 months:
You’ll experience major transformation — typically 10–15 kg lost, with a noticeable change in confidence and energy.
Why Mounjaro Works Better Than Diets
Unlike diets that cause short-term water loss, Mounjaro encourages your body to burn stored fat while preserving lean muscle.
It also stops the “rebound” effect that often follows crash dieting.
| Aspect | Traditional Diet | Mounjaro |
|---|---|---|
| Appetite control | Temporary, relies on willpower | Long-term, hormone-driven |
| Weight regain | Very common | Rare with consistent use |
| Fat loss vs muscle | Muscle loss common | Focused on fat loss |
| Sustainability | Difficult | Designed for long-term success |
This combination of dual hormone activation makes Mounjaro more effective than single-action treatments like Ozempic or Wegovy.
How to Maximise Weight Loss with Mounjaro
While the medicine does most of the work, your lifestyle habits can accelerate your progress.
1. Eat Balanced, Protein-Rich Meals
Include lean protein at every meal — it keeps you fuller and supports fat burning.
2. Stay Hydrated
Drink 1.5–2 litres of water daily to aid digestion and prevent nausea.
3. Move Your Body
Even 30 minutes of walking or light exercise per day can enhance your results.
4. Be Consistent
Inject on the same day each week — consistency helps stabilise your hormones.
5. Get Enough Sleep
Poor sleep disrupts appetite hormones. Aim for 7–8 hours per night.
