Mounjaro Weight Loss Journey | Before & After Month 1 Results

I’ve just completed my first month on a GLP-1 medication, and I wanted to bring you along on this Mounjaro weight loss journey as I share all the ins and outs, plus my before and after pictures and progress along the way. It’s clearly a topic that, a lot of people are very interested in right now.

As a health coach, I’ve always said there is no magic pill…

…and yet here we are.

So I want to share my honest experience — week by week — and at the end I’ll also share my Mounjaro weight loss before and after results from month one.

My Apprehensions Before Starting

Going into this, I did have a lot of apprehensions.

If you missed my first post, you can check that out HERE explains my reasoning behind starting and the fears I had around making this decision.

These medications come with warnings. They can have side effects. This wasn’t something I went into lightly.

But one month in, I can honestly say:

I don’t regret starting.

From the beginning, my intention has been to be open and transparent about this journey — and that’s exactly what I want to continue doing.

My Biggest Struggle Before GLP-1

Before starting, I struggled with constant hunger.

I would get episodes where if I didn’t eat, my blood sugar would drop and I’d feel shaky — that “hangry” feeling where you need to eat immediately.

My challenge was never my main meals.

It was the afternoons.

I would get an energy dip, feel intense hunger, and go to the cupboard. I might start with something healthy like a rice cake or an apple — but it would never satisfy me.

Then I’d end up eating crisps, biscuits, chocolate…

And there was no stop button.

Week 1: The Immediate Change

The very first thing I noticed in week one was this:

The constant, powerful hunger disappeared.

I still felt hungry, but it felt normal. Balanced.

I continued eating three solid meals per day because I wanted to do this the right way. I wasn’t interested in starving myself or just eating junk in smaller amounts.

I focused on:

• Protein at every meal
• Whole foods
• Plenty of vegetables
• Good quality fats

My breakfast remained my usual protein smoothie, something I’ve had for years, and I continued adding psyllium husk to support digestion.

And the biggest difference?

No urge to snack between meals.

How My Eating Habits Changed

I haven’t tracked food during this process.

That was intentional, I wanted freedom from obsessing over food.

Instead, I’ve been using a simple hand-portion method:

• Half plate vegetables
• Palm-sized protein
• Healthy fats

I’ve also prioritised nutrient intake because I know hair loss can happen if the body isn’t properly nourished.

So I’ve made sure to include:

• Good quality whole foods
• Fish oil
• Avocado
• Plenty of fibre

What Happens With “Unhealthy” Foods Now

I’ve still eaten out and had occasional treats.

But what I’ve noticed is:

If I eat heavy, fried, processed foods, I quickly feel sick.

So naturally, I gravitate toward healthier options — lots of vegetables, salads, and whole foods.

For me, this journey has been about reducing highly processed, calorie-dense foods while keeping all the nutritious foods in.

Digestion: A Surprising Improvement

One of the most surprising changes has been digestion.

Many people report digestive issues on GLP-1 medications — but for me, it actually improved significantly.

I’ve struggled with digestion for years, often experiencing:

• Constipation
• Bloating
• Discomfort

But over this first month:

• I’ve been more regular
• Bloating has reduced dramatically
• My stomach feels much more comfortable

Reducing gluten and wheat has also made a noticeable difference.

Week-by-Week Weight Loss

Week 1

I lost 4 pounds (2 kg).

This was more than expected, and likely included water weight.

Week 2

I lost 1 pound.

I focused on consistency, strength training, and maintaining habits.

---

Week 3

Another 1 pound lost.

Appetite remained stable and food noise continued to stay low.

Week 4

I lost 2 pounds.

Total Month 1 Results

Over four weeks, I lost:

8 pounds (3.6 kg)

Body Measurements & Changes

I also tracked measurements, which showed significant changes:

• Neck: –1.5 cm
• Arms: –1 cm each
• Chest: –3 cm
• Waist: –4 cm
• Belly: –10 cm
• Hips: –2 cm
• Thighs: –1 cm each

Total reduction across the body:

25 cm (around 10 inches).

This was especially meaningful because I hold weight around my midsection — and reducing belly fat also lowers health risks linked to visceral fat.

This is the smart tape measure I am using from Rempho to more easily measure and track my progress through using the app that comes with it.

Strength, Training & Energy

One of my biggest surprises has been strength.

I expected to feel weaker due to eating less — but actually:

All my lifts have increased.

I feel incredibly strong.

Energy levels have generally been good too. Any fatigue I’ve experienced has been more related to:

• Busy winter lifestyle
• PCOS
• Sleep variations

But overall, I feel energised.

Lifestyle Habits Supporting My Results

I’ve been very consistent with:

• Strength training
• Daily movement (~15,000 steps/day)
• Protein intake
• Hydration
• Sleep routines

I’ve deliberately avoided adding extra cardio because my daily activity levels are already high.

Reduced Food Noise & Sugar Cravings

Perhaps the biggest mental shift has been:

Quieting of food noise.

I still occasionally crave sweets, especially when tired, but now I have the space to pause and ask:

“Do I actually need this?”

This has helped reduce sugar intake significantly — which is especially important for improving insulin resistance.

Supplements Supporting My Journey

To support my health during this process, I’ve been using:

• Lean Greens (for nutrients, collagen, creatine, gut support)
• Happy Mammoth Gut Health
• Psyllium husk

Together, these have helped reduce bloating and improve digestion.

How I Feel After One Month

Honestly…

I feel like I’ve gone back 10 years.

Not just because of weight loss — but because:

• I feel comfortable in my body again
• I feel motivated to train
• I have freedom from constant food thoughts

My Plan Going Forward

I’m staying on the lowest dose (2.5 mg) because it’s working.

My long-term goal has always been:

• Use this tool temporarily
• Improve health habits (reducing sugar and snacking)
• Transition into maintenance

Because this only works long-term if you also change lifestyle behaviours.

Final Thoughts After Month One

This experience has reinforced something I already believed:

GLP-1 medications can be life-changing when approached the right way.

Not as a shortcut — but as a tool alongside healthy habits.

What’s Next

I’ll continue sharing monthly updates as this journey progresses.

If you have questions, leave them in the comments — I read every single one.

And I’m considering creating a guide on:

“How to Do GLP-1 the Right Way”

If that would be helpful, just comment GUIDE and I’ll put it together.
