For long term weight loss Mounjaro won’t do it all

Tanya Reynard | Last update: 23rd June 2025

You’re on weight loss drugs. Now what?

Let’s be real. GLP-1 weight loss drugs are game-changers. They suppress appetite, help regulate blood sugar, and kickstart weight loss in a way that feels impossible for many of us.

But they won’t fix everything.

And if we’re not careful, they can lull us into thinking we don’t have to do much else.

This is your gentle wake-up call from the SlimrChat community: you still need to show up for yourself, especially if you want long-term weight loss.

“I let the drugs do the hard work… then hit a wall”

“I’m a dietitian, and I still made mistakes on Mounjaro. I let my appetite disappear, skipped meals, didn’t work out, and hit a plateau hard.”

Sound familiar? Many in our community have been there.

The truth is: yes, these meds work. But they work best with you, not instead of you.

Weight loss without movement = muscle loss

You’ll lose weight on GLP-1 weight loss drugs. But if you’re not moving your body and eating enough protein, a chunk of that weight loss will be muscle.

Why does that matter?

• Muscle drives your metabolism: more muscle = more calories burned, even at rest
• Muscle keeps you strong and energised
• Less muscle = harder to maintain weight loss long-term

“When I started walking daily and upped my protein, my energy improved and I stopped feeling like a zombie on the meds.”

What happens if you eat whatever you want?

We get it. Your appetite is down, so it feels like the perfect time to eat what you fancy in small amounts.

But:

• Ultra-processed foods can still cause inflammation, blood sugar crashes, and digestive issues.
• You may be undernourished, fatigued, or prone to side effects like nausea and constipation.

The good news?

You can still enjoy your favourite foods — you just need a baseline of nutrition to support your body and your progress.

What does “Showing up” look like?

You don’t have to become a gym junkie or go full clean-eating mode. But a few simple shifts can make a huge difference:

• Prioritise protein at every meal — aim for 25–30g per meal
• Start resistance training and walking regularly
• Don’t skip meals, even when you’re not hungry
• Focus on balanced meals: protein + fibre + healthy fats + smart carbs
• Stay hydrated (but no need to glug a gallon of water)

“I built my meals using a guide designed for GLP-1 users. No generic weight loss advice. I felt so much better.”

Want to stop the treatments eventually? This is how.

The ultimate goal for many of us? Getting off the meds and keeping the weight off.

To do that, you must create habits that will carry you when the appetite suppression fades.

“I realised I needed to stop relying on the shot and start building a lifestyle. That’s when things clicked.”

Build muscle. Eat real food. Move regularly. Sleep well. Stay connected to your why.

It’s not about perfection — it’s about consistency.

Quick recap

GLP-1s are powerful, but they can’t:

• Build your habits for you
• Maintain your muscle mass
• Fuel your body with quality food
• Keep the weight off once you stop

They’re the assist. You are the driver.

To get the most from your weight loss journey:

• Eat enough protein
• Move regularly
• Don’t skip meals
• Let the drugs support, not replace, your effort
