About me

After completing my training as a Medical Practice Assistant, I pursued a Bachelor of Science in Nutrition & Dietetics part-time.

Subsequently, I worked for five years at the University Hospital Zurich, where I primarily cared for individuals with eating disorders, oncological conditions, and complex digestive and nutritional problems.

In addition to my professional training, my personal experience also shapes my work: A period of burnout and exhaustion showed me how deeply the body and nervous system are connected and that sustainable change requires more than just knowledge.

Central to my approach is that people feel understood, safe, and well-supported.

About Me

I founded ViaSlim to address the growing burden of chronic diseases in Switzerland. My goal: a medical approach that not only treats symptoms but also identifies their root causes, restoring energy, quality of life, and balance to patients.

Since founding ViaSlim in 2024, I have seen how patients with overweight conditions significantly recover and improve chronic complaints within the first year through personalized programs.

About Me

My name is Ana Lasica. I am a physician and Chief Growth Officer at ViaSlim. I completed my medical studies here in Switzerland – in Fribourg and Bern – and then immediately began working in internal medicine. In emergency rooms, intensive care units, and regular wards, I repeatedly encountered patients with obesity. And I saw how profound this disease is – it affects not only the body but a person's entire life. Yet, in the healthcare system, it often isn't treated as effectively as it should be.Then I took a different path. I joined the medical team of one of the major pharmaceutical companies in the GLP-1 field, where I was able to delve deeply into the latest science surrounding metabolic health and modern obesity therapy – and get to know various treatment centers in Switzerland. During this time, I often realized: The possibilities that modern obesity medicine offers today are enormous – but they still too rarely reach patients in the right way. And at that very moment, it became clear to me: I want to go back to the patients. I want to apply this knowledge directly. That's exactly what I found at ViaSlim.I believe that everyone has the right to understand their health and make self-determined decisions.

About me

My focus is on a holistic and psychologically-informed approach to supporting individuals with overweight and obesity. As a psychologist (M.Sc.) and health coach, it's particularly important to me to address not only eating habits but also the emotional and mental factors behind weight.

Through my own experience with obesity, binge eating, and food noise, I understand the challenges many affected individuals face, not just from a professional but also from a personal perspective. That's precisely why empathy, understanding, and support on equal footing are central to my approach.

My approach is free from pressure and focuses on sustainable changes that are achievable in everyday life.

Why ViaSlim?

At ViaSlim, as a patient myself, I felt heard and understood from the very beginning. It was the first time a doctor communicated with me as an equal and took me seriously. I'm also succeeding for the first time in losing weight sustainably and preventing my emotional eating episodes. I've never felt this good!

Because I know the struggles of those affected so well, I now want to help them as part of the ViaSlim team so that they too can finally feel understood and address their issues with medical and psychological support.
