Childhood & High School

The Beginning

I don’t have a single memory from my childhood where I wasn’t overweight or where I felt good about my body.

I’ve struggled with my weight for my entire life. I was bullied, had extremely low self-esteem, and I coped with food.

🍫

In high school, I remember eating a whole tub of Pringles and 2-3 Snickers bars almost every single day.

University

Rock Bottom #1

Then I went to university. Living alone, not knowing how to cook, eating out constantly, and drinking with friends…

The First Attempt

I Lost 23 kg… The Wrong Way

That’s when I first truly tried to lose weight — and I did. I lost ~23 kg over the course of a year:

But I did it in the worst way possible. Less than 1,000 calories a day. Tracking everything — including lettuce and cinnamon. Punishing myself with ‘Insanity’ HIIT workouts.

This guy used to haunt me… 😅

I ended up skinny fat. And still not happy.

The Rebound
📈

As soon as the diet was over, I went all-out bingeing and gained back 15 kg in just 3 months.

I felt like a complete failure.

That’s when I started learning. I got into science-based fitness, watched and learned from experts, and finally got into relatively decent shape:

Then COVID Happened. 😔

Gyms closed. My motivation died.

I started ordering food twice a day, every single day, and over the next 3 years…

May 2023 · The Turning Point

The Breaking Point 🔥

That’s it. I’m done. I’m getting my life back together.

I turned 26 and something finally clicked.

This time, I didn’t starve myself. I didn’t do extreme workouts. And I didn’t cut out all my favorite foods.

I focused on building real habits:

🥩 Eating protein at every meal

🚶 Walking daily

🏋️ Training properly

🧠 Finding an approach I could stick to for life

And it worked.

Now I Help Others Do the Same 💪

Now, I’m in the best shape of my life, both physically and mentally. I became a certified Nutrition Coach and Personal Trainer, and all I want to do now is help people.

I want to help people who feel stuck, who have tried everything, who feel like losing weight is impossible for them.

💛

Because that was me.

I know exactly how it feels to struggle, to fail, to feel like nothing will ever work. If I could go back in time and help my younger self avoid all the mistakes, the frustration, and the years of self-doubt, I would do it in a heartbeat.

But I can’t. What I can do is help you.

And It Works for My Clients Too 🙌
