Weight loss drug tips and the mistakes to avoid for staying on track
Robert Price | Last update: 18th June 2025
Weight loss drugs like Wegovy and Mounjaro have opened up a whole new chapter for many of us who’ve battled with our weight over the years. But long-term success comes down to more than just the drugs — our mindset, habits, and the little changes we make to keep us moving forward.
So, whether you’re just starting out or have already faced a few bumps in the road, here’s a friendly guide to help you dodge common pitfalls and stay on course towards a healthier and happier you.
Mistakes to avoid
1. Trying to change everything quickly
It’s natural to feel excited and want to transform your entire lifestyle from day one — overhauling your diet, hitting the gym, drinking gallons of water. Enthusiasm can quickly fizzle out so take a gentler, more effective approach. Tackle one change at a time. Maybe it’s adding a bit more protein to your meals or going for a short walk each day. Small wins build momentum — and they’re much easier to stick to.
2. Expecting overnight results
Weight loss drugs can be incredibly effective, but they’re not an instant fix. Often, it takes a little time for the treatments to reach full potential, especially in those early weeks as doses are gradually increased. While you’re waiting for the numbers on the scale to budge, keep an eye on other victories — maybe you’re sleeping better, feeling less out of breath, or slipping into clothes that used to feel tight. Progress comes in many forms!
3. Relying on the treatments alone
Weight loss drugs are a brilliant tool, but they work best alongside healthy habits — think balanced meals, gentle movement, and a bit of planning. Rather than seeing the treatment as “doing the work,” treat it as a helpful partner on your journey.
4. Skipping meals
One of the most noticeable effects is a reduced appetite. But skipping meals altogether can backfire, leaving you drained, lightheaded, or short on key nutrients. Try to nourish yourself with small, balanced meals packed with protein, fibre, and healthy fats. Your body — and your energy levels — will thank you.
5. Don’t throw in the towel
Weight loss isn’t always a straight line, and the scales don’t always reflect your efforts straight away. Take a broader view: track your progress with photos, measurements, or even by noticing how you feel in your own skin. And don’t forget to celebrate the small wins along the way — they’re all part of the bigger picture.
6. Brushing off side effects
Mild side effects like nausea or constipation are common, especially early on. Don’t let them derail you. Simple tweaks — staying hydrated, eating smaller portions, adding more fibre — can often help. And if problems persist, it’s worth having a chat with your healthcare provider. There’s no need to tough it out alone.
7. Going it alone
Let’s be honest — weight loss can feel lonely at times. It doesn’t have to be that way. Join a supportive community, whether online or in person, and it will make all the difference. Places like SlimrChat are brilliant for seeing more tips, sharing success stories, and finding a little boost on the tougher days.
