If you’ve tried diet and exercise but still carry stubborn fat around your belly, hips, or thighs, you’re likely exploring prescription options. Many UK patients are now asking: “Mounjaro vs Saxenda — which is better for stubborn fat?”
At PPRX, we offer both options through private prescription. Here's how they compare and what you should consider if you're targeting hard-to-lose fat.
What Are Mounjaro and Saxenda?
- Mounjaro (tirzepatide) is a once-weekly injection. It’s a dual GIP and GLP-1 receptor agonist that reduces appetite, slows digestion, and improves insulin sensitivity.
- Saxenda (liraglutide) is a once-daily GLP-1 receptor agonist, used in the UK since 2017 for weight management.
Which One Works Better for Stubborn Fat?
Effectiveness
- Mounjaro: Average weight loss of up to 20% of body weight in trials.
- Saxenda: Average weight loss of 6–10%.
Mounjaro tends to work faster, particularly for visceral fat and areas resistant to diet changes.
Ease of Use
- Mounjaro: Inject once a week.
- Saxenda: Inject daily.
Weekly dosing is more convenient and improves long-term adherence.
Impact on Belly Fat
Both drugs reduce central fat, but Mounjaro has shown stronger results in reducing waist size and improving markers linked to metabolic fat.
Side Effects
- Mounjaro: nausea, constipation, reduced appetite (typically milder after week 2)
- Saxenda: nausea, headache, possible injection site reaction
Mounjaro’s weekly dose may be easier to tolerate long term.
Which Is More Affordable?
Saxenda pens are generally more cost-effective upfront, but Mounjaro may offer better value due to its stronger results at lower doses and reduced injection frequency.
