Laura Konstantinović

As a mom of a teenager, juggling work and school left my eating habits far from ideal – skipping breakfast, relying on coffee and pastries, and eating sweets regularly. This caused digestive issues, fatigue, and a feeling of heaviness.

Two years ago, I started with Herbalife Nutrition. In just two months and four challenges, I added a healthy breakfast, improved digestion, and eliminated fatigue. My body composition also improved.

I realized that change doesn’t have to be complicated – small steps can make a big difference. Now, I have more energy and less stress, and I help others find simple solutions for better health and energy.

Duško Žigić

As an entrepreneur, my business travels, lunches, dinners, and sedentary lifestyle led to weight gain. At 182 cm, I reached 104 kg, feeling unwell and low on energy. In 1999, a friend introduced me to HL nutrition.

By adopting new dietary habits and drinking enough water, I lost 14 kg and 15 cm around my waist in just 90 days. After only a few days, I started feeling fantastic, and people around me noticed the change.

Thanks to my own experience, I’ve been helping clients for 25 years, supporting their transformations with excellent results. I’ve helped thousands of clients, and I can help you too on your journey to a healthier, happier life.

What Clients Say

Željko, Maribor

I started using Herbalife products about a month ago, and here are some changes I’ve noticed! In less than a month, I’ve lost about 8 kilograms, and my waist, chest, and hip measurements have each decreased by approximately 10 centimeters. I feel much healthier, more agile, and I absolutely plan to continue using Herbalife products and maintaining healthy habits! I’d also like to praise the expert team, who are always there to provide support and answer my questions.

Slide
Nina, Belgrade

So, 3 cm less in the chest, 3 in the waist, and 6 in the hips since the last marathon.

Slide
Matea, Zagreb

When you see results, it motivates you—and that’s the most important thing.
14 cm, 4 kilograms, 1% body fat, and 4 years of life regained in just one month. That’s no small thing.

Slide
Irena, Zagreb

A good mentor, group support, and photos—I never would have thought of trying this on my own. The advice and motivation... This isn’t just my success; it’s our collective success!
That said, I didn’t start this journey for the numbers; I started for health reasons (I could no longer tie my own shoes). Climbing three flights of stairs felt like scaling Mount Everest… Thank you all! The help I received has been truly invaluable.

Slide
Vlada, Maribor

Six months ago, I couldn’t run 100 meters… Thank you for your support over all these months… we’re moving forward with even more determination.

Slide
Marija, Belgrade

More energy, -2.4 kg, improved digestion, and no bloating.

Slide
Sandra, Belgrade

In the second round of the fit marathon, I lost 1.4 kilograms, 3% body fat, and 18 cm overall. I have so much energy, confidence, and I’m thrilled with the results

Slide
Anita Boceva, Macedonia/Netherlands

Hi, I’m Anita Aleksic, born in Bitola, Macedonia, and living in Holland. I’m 50 years old. This was my first fit marathon with Sandra, and I lost 2.5 kilograms. I feel amazing and will continue working towards my goal.

Slide
Andreja, Zagreb

Thank you for the support—I couldn’t have done it alone without the entire team and, of course, the guidance of our leader. I’m definitely signing up for the next round.

Slide
Violeta, Serbia/Italy

With Herbalife products, results are guaranteed. I started at 96 kilograms before my first marathon and reached 86.8 kilograms. I’m grateful to Laura, Duško, and the entire team for the motivation.

Slide
Ivana, Zagreb

Today, someone told me I’ve lost my belly and shaped my waist and legs.

Slide
Aleksandra, Osijek

Wow… Did I lose the most weight here? By summer, I’ll be like a rocket—or a toothpick!
Thanks, Fit Marathon.

Slide
Gordan, Zagreb

I never expected it would be possible to lose so many kilograms and centimeters in less than a month. Thank you, Duško and the team, for this amazing journey.

Slide
Ivana, Split

Now, let someone tell me, “That’s just chemicals.”
Wow, what results!

Slide
Ivana, Split

I can’t believe I’m saying this, but at the moment, my weight doesn’t even matter. For the first time since 2012, I’ve been able to sleep through the night. I no longer need to nap during the day, and in the evening, I have so much energy—even with work and two kids that I’m currently taking care of on my own. My goal now is that, come April, my husband won’t recognize me at the airport because on December 9, he left a woman who weighed 100 kilograms.

Slide
Violeta, Serbia/Italy

I started this journey by chance out of curiosity eight years ago and achieved amazing results. I reduced my measurements and dropped six dress sizes while increasing my energy. I no longer needed to nap during the day and could stay active late into the night. At 38, I began treatment for high blood pressure, but over time, I’ve reduced my medication intake. These past two years, these marathons have been incredibly meaningful to me—primarily for the motivation, team support, and mentorship, which I truly missed.
