About me

After training as a registered dietitian (BSc), I worked for several years at Glarus Cantonal Hospital before moving on to the Centre for Internal Medicine in Aarau for many years. There I worked in both outpatient and inpatient settings. This combination showed me how valuable it is to accompany people along their entire journey. In the process, I became increasingly interested in what moves people when it comes to food: habits, emotions, experiences and everyday life shape our eating behaviour just as much as knowledge does. This holistic view has become my focus. To deepen it, I have undertaken further training in nutritional psychology and clinical hypnotherapy.

Education & qualifications

• Bachelor of Science in Nutrition and Dietetics, Bern University of Applied Sciences
• CAS Applied Nutritional Psychology, Bern University of Applied Sciences
• Foundation course in clinical hypnotherapy, Swiss Institute for Medical Hypnosis

Why ViaSlim?

I am excited by modern medicine and the pace at which it is evolving. At ViaSlim I actively help shape what the nutrition coaching of the future looks like: evidence-based, creative and close to the people we support.

About me

After training as a medical practice assistant, I completed a Bachelor of Science in Nutrition & Dietetics alongside my work.

I then worked for five years at University Hospital Zurich, where I mainly cared for people with eating disorders, oncological diseases and complex digestive and nutritional problems.

Alongside my professional training, my personal experience also shapes my work: a period of burnout and exhaustion showed me how closely the body and nervous system are connected and that sustainable change takes more than knowledge alone.

Education & qualifications

• Medical Practice Assistant EFZ (2009–2012)
• Vocational baccalaureate in health and social care (2013-2014)
• Bachelor of Science in Nutrition & Dietetics (2016–2020)
• Yoga teacher (200h, 2024)

Why ViaSlim?

Sustainable change happens where physical, psychological and behavioural factors are considered together.

At ViaSlim I have the opportunity to support patients in an evidence-based, individual and holistic way – with nutrition coaching that goes beyond counting calories, plans and weight targets.

For me, the key is that people feel understood, safe and well supported.

About me

My name is Ana Lasica. I am a physician and Chief Growth Officer at ViaSlim. I completed my medical degree here in Switzerland – in Fribourg and Bern – and then went straight into internal medicine. In emergency departments, intensive care units and general wards, I encountered patients with obesity again and again. And I saw how profound this disease is – it affects not only the body but a person's entire life. And yet the healthcare system often does not treat it the way it should. 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 immerse myself in the latest science on metabolic health and modern obesity therapy – and to get to know various treatment settings across Switzerland. I often found that the possibilities modern obesity medicine offers today are enormous – but they still reach patients in the right form far too rarely. And at that very moment it became clear to me: I want to go back to patients. I want to put this knowledge to use directly. That is exactly what I found at ViaSlim. I believe that every person has the right to understand their health and to make self-determined decisions.

Why ViaSlim?

‍Because here I can practise medicine the way I have always wanted to: truly understanding people, recognising connections and developing solutions – together with doctors, nutrition and lifestyle experts.

About me

My particular interest lies in modern, scientifically grounded care for people with obesity. In my previous work in internal medicine and endocrinology, I have supported many people with metabolic diseases. I have learnt that nutrition, exercise, sleep and how we deal with stress are important foundations for our long-term health, and that treatment goes far beyond mere weight loss.

At the same time, it takes modern medical treatment that takes scientific evidence into account and is tailored to each person's individual needs. I want to support my patients on their personal health journey with my medical knowledge and our team – because long-term change works best when you do not have to walk this path alone.

Education & qualifications

• Medical degree, Medical University of Innsbruck
• Specialist training in General Internal Medicine
• Clinical experience in endocrinology & diabetology
• Research work in the field of gastrointestinal diseases and obesity in Boston, at Aarau Cantonal Hospital and University Hospital Zurich

Why ViaSlim?

Because here I can practise modern obesity medicine the way I envision it – with a motivated team, modern therapeutic approaches and the shared goal of promoting health in the long term. At ViaSlim, a healthy, sustainable relationship with weight is at the centre for me – not just the number on the scales.

In recent years I have worked as a general practitioner, supporting patients in their everyday lives – where health is truly lived. My particular focus is on metabolic and hormonal medicine: I support patients on their path to a healthy weight, stable hormones and lasting well-being. I rely on evidence-based therapies – from nutrition and exercise to modern medical treatments.

About me

While working as a personal trainer, I decided to deepen my knowledge with a degree in nutrition and dietetics. Today I combine my experience from sport and nutrition coaching and support people on their path to better health and well-being in an evidence-based way. I have gained professional experience in an obesity centre, in the fitness sector and currently at ViaSlim, among others.
