A brighter tomorrow, together.
How KO works
Free 30 minutes with your coach. You talk through what you have tried so far, what you want to achieve and how we can make your changes sustainable together.
You have one dedicated coach for the whole programme. Together, you build a practical plan for eating, movement and sleep, and find coping mechanisms for difficult moments.
A BIG-registered doctor reviews whether treatment is medically appropriate and discusses your options with you.
Your treatment is combined with weekly check-ins, coaching and practical support.
From day one, you work on habits that will continue even when your treatment changes or ends.
The complete programme is shown below. Personal coaching focuses on your coach, check-ins and habits.
Our approach
Many people who come to us have already tried a lot. What was often missing was not motivation, but a plan that continues to work when things get difficult. That is why KO does not start with a prescription. We start with you, and one coach who knows your story. Together you work on eating, movement, sleep, and identify the moments that in the past have derailed your progress. Medication can create room for change. Our support helps you hold on to it.
A BIG-registered doctor assesses what is appropriate.
Prescribed only after consultation with the doctor.
One dedicated coach for the whole programme.
Eating, movement, sleep and stress, in small steps.
A practical plan that fits your work, family and difficult days.
A plan for what comes next, when treatment changes or ends.
Medication can make the first step easier. With support and new habits, you can keep going.
Personal coaching
You do not have to start over at every appointment. Your dedicated coach gets to know your goals, daily life and relevant health context, and builds on what you have already shared.
A question does not have to wait until your next check-in. You can message your coach anytime, whenever it suits you.
No standard list of rules, but small steps that feel achievable. Together with your coach, you work on nutrition, movement, sleep and stress, all adapted to your work, family life and the days when things do not go as planned.
During weekly check-ins, you and your coach look at how things are going. If something does not go as planned, you simply adjust the plan together.
Medical care
Your coach helps you build healthy habits, establish structure, and stay consistent. Medical decisions are made by a BIG-registered doctor with specialized expertise and experience in weight management. The doctor assesses whether treatment is suitable for you, prescribes medication when appropriate, and discusses what is medically safe and responsible for your individual situation. Following medical approval, your doctor may prescribe semaglutide (Ozempic) or tirzepatide (Mounjaro). Your medication is dispensed by a registered Dutch pharmacy.
Clear and transparent
Everything you need to start with confidence, explained clearly.
Your personal information is treated confidentially and is only used for your coaching and treatment, in accordance with applicable privacy legislation.
Your first conversation is free and does not commit you to anything. You get to know your coach, ask all your questions and then decide in your own time whether you want to continue. No pressure, no sales pitch.
You know what to expect before you start. We explain the cost of the programme and what is included, so there are no unexpected surprises.
You are not the only one. Many people who come to us have already tried different diets and programmes. That says nothing about your determination. It often means you have not yet had the right support. Together, we look at what did not work before and what you need to approach things differently this time.
Having a difficult week or struggling with something? Your coach is there for you, including between your weekly check-ins. You do not have to figure everything out by yourself.
There is no rush and no ideal image you need to live up to. Together with your coach and doctor, you decide which steps are right for you and adjust the plan when needed.

Client experiences
The intake was not just about my weight. We also talked about work, sleep and difficult moments. That made the plan feel genuinely personal.
Joe, 42
Feeling heard
I liked being able to send a question between appointments. We picked it up together at my check-in, without me having to explain my whole story again.
Karen, 36
Support between visits
We started with a few small changes that fitted my week. It was not about doing everything perfectly, but working out together what was realistic.

Why KO
You do not have to start over at every appointment. Your dedicated coach gets to know your goals, daily life and relevant health context, and builds on what you have already shared.
A question does not have to wait until your next check-in. You can message your coach anytime, whenever it suits you.
No standard list of rules, but small steps that feel achievable. Together with your coach, you work on nutrition, movement, sleep and stress, all adapted to your work, family life and the days when things do not go as planned.
Choose coaching without medication or the complete programme. For a medical programme, a BIG-registered doctor assesses what is appropriate. Your coach supports the everyday work.
We look beyond getting started. You work on habits from day one and discuss the support you need when treatment changes or ends. Medical changes are discussed with the doctor.
Personal coaching from €99 per month, with medical guidance from €149 per month. No sign-up fee and no charge per conversation.
My story
You should not have to figure it all out alone.
Weight has been a personal topic for me for as long as I can remember. As a child and young athlete, I was often the chubby girl in the team. I trained hard, but I also noticed something important: when I lost weight, I felt more confident and performed better.
That confidence changed a lot for me. I went on to become a Ukrainian champion in two sports: sports aerobics and fitness. Looking back, I understand that it was not simply about becoming lighter. It was about how I felt about myself.
That curiosity eventually led me to study psychology. During my Master's degree, I became particularly interested in the relationship between stress, emotions and eating behaviour. It was not only an academic subject for me. I knew from my own experience what it was like to eat in response to stress and to struggle with patterns that were difficult to change.
I have spent more than 20 years working in the fitness and wellness industry. Over time, one thing became very clear to me: exercise alone is rarely the whole answer. How we eat, move, sleep, manage stress and live our everyday lives all matter.
After moving to the Netherlands, I started my own coaching programme and wrote a book for people who wanted to lose weight. Later, my career took me into the corporate world, working on fitness, health and innovation.
In 2025, I became fascinated by the development of GLP-1-based treatments. I saw how powerful they could be as an additional tool for people struggling with weight. But I also became convinced that medication works best as part of a bigger picture.
Medication can make the first step easier. With support and new habits, you can keep going.
After supporting several people together with a doctor, I saw how much difference it made when someone had both appropriate medical care and a person beside them who knew their story.
That is why I created KO.
I want KO to be the place where you are known as a person. Where someone thinks things through with you, supports you when things get difficult and helps you choose a realistic next step.
Because lasting change is not only about what treatment you take.
It is about building a way of living that works for you.
