Gewichtsverlies

Ons verhaal
Jake Prins en Andreas Niessl, oprichters van Lean Clinic

We hebben van dichtbij gezien hoe mensen jarenlang worstelen met overgewicht, en hoe weinig bestaande oplossingen écht werken. Als levenslange vrienden, met een gedeelde passie voor leefstijl en gezondheid, hielpen we al ruim vijftien jaar geleden mensen met afvallen. Het onderwerp heeft ons nooit losgelaten.

Maar na onze studie gingen we eerst ieder onze eigen weg. Andreas verdiepte zich verder in de obesitaszorg en werkte jarenlang bij de grootste klinieken van Nederland. Hij begeleidde meer dan duizend mensen één-op-één en zag van dichtbij hoe groot het effect van GLP-1-medicatie kan zijn, maar vooral hoeveel meer er mogelijk is als je leefstijl en gedrag echt serieus neemt.

Jake sloeg een andere weg in. Na op topniveau te hebben gebasketbald en een boek over leefstijl te hebben gepubliceerd, belandde hij in de wereld van software en technologie. Zorgplatforms, educatieve apps, zijn eigen softwarebedrijf.

Als vrienden spraken we vaak over de obesitaszorg en waarom het probleem in Nederland alleen maar groter werd. GLP-1-medicatie verandert veel, maar een aanpak die medische zorg écht combineert met leefstijlverandering en technologie? Die ontbrak.

Die gesprekken werden plannen. Die plannen werden een platform. We verzamelden een team van artsen dat gelooft in dezelfde aanpak. En nu staan we hier, met echte resultaten en een missie die nog lang niet af is.

Want dit probleem verdient een aanpak die verder gaat dan alleen medicatie.

Why Lean Clinic?

Excess weight has been a growing problem in the Netherlands for far too long. The health risks are serious, and existing solutions simply don't work well enough. We've seen up close what works and what doesn't. That's why we combine medical guidance, lifestyle change and technology into one approach. And we see that it works.

The problem

More than half of adults in the Netherlands are overweight. Obesity is a medical condition, increasingly described as a "gateway disease" that raises the risk of more than 200 other conditions. Not just physically, but mentally too. It affects your energy, your health, your confidence.

Diets, exercise plans, weight-loss programmes, they've been around for years. Yet the problem keeps growing. Because it's a complex issue with no simple solution.

Feiten en cijfers

1 op de 2 volwassenen

Meer dan de helft van de volwassen Nederlanders heeft overgewicht. Bij 1 op de 6 is sprake van obesitas.

Een groeiend probleem

Het aantal mensen met obesitas is de afgelopen decennia verdrievoudigd en neemt nog steeds toe.

Medicatie + leefstijl werkt

GLP-1-medicatie in combinatie met leefstijlbegeleiding laat consistent betere resultaten zien in klinisch onderzoek.

Digitale zorg helpt

Online begeleiding verhoogt therapietrouw en verbetert aantoonbaar de resultaten bij leefstijlinterventies.

Our approach

Lean Clinic is built on three pillars. Each one equally important. Together, they make the difference.

Three pillars of Lean Clinic: lifestyle, medical and technology
  1. Real lifestyle change: not diets you abandon after three weeks, but guidance that fits your life. Building healthier habits, one step at a time.
  2. Medical guidance: GLP-1 medication under the supervision of experienced doctors. Safe, responsible and effective. The medication is there to support you.
  3. Everything in one place: track your progress, stay in touch with your team, get guidance whenever it suits you. 100% online, always available.

What we stand for

Lifestyle as the foundation, not an afterthought

We started as lifestyle coaches. You can feel that in everything we do. Medication can be a powerful tool, but real change comes from changing your behaviour. We help you not just lose weight, but improve your health and quality of life.

Digital and responsible

We believe online care can actually be better. Good monitoring, easy access to your team, support when it suits you. Without compromising on quality or safety.

Honest and transparent

We're open about how our treatment works, what you can expect and what you can't. Not everyone is the right fit for our programme, and we'll tell you that honestly.

Always improving

The science around GLP-1 medication, lifestyle interventions and technology moves fast. We keep up with the latest developments and continuously refine our approach.

The programme

This is what the Lean Clinic programme looks like

Lifestyle modules, personal coaching, a warm community and ongoing medical supervision. All in one structured programme.

Reviews & experiences

Experiences with medical weight loss at Lean Clinic

Real experiences from real people

Exactly what you need for a lifestyle that lasts

I'm so glad I started at Lean Clinic. The online contact is open and honest, and you notice straight away how knowledgeable and committed they are. You genuinely feel seen and heard: these are experienced professionals who understand what you need, at every stage of your programme. The extensive library, the practical tips, the clear explanations and the loyalty programme all help you build a lifestyle that lasts. And it's affordable too. I'm a fan!

Pauline

Professional and warm support

From the very first contact it felt clear, transparent and carefully thought through. No empty promises and no one-size-fits-all approach, but a programme that really looks at the person behind the goal. Respectful, engaged and approachable, without ever becoming pushy. You feel heard and taken seriously, and that matters enormously when you're working on something as personal as your health.

Serina

An educational journey with good support

I'm very happy with my programme at Lean Clinic. The advice is expert, the platform is pleasant to use and you genuinely learn something from the modules. They're also always easy to reach for a quick question or a bit of extra advice.

Dora

So much more than just losing weight

A team that stays positive, thinks along with you and never judges. Having both a doctor and coaches beside you builds trust, and the weekly online programme helps you build new habits step by step. No harsh perfectionism, just room to be human.

Anna

A programme with great guidance

Clear information on the website. The intake with the doctor was scheduled quickly and went smoothly. Throughout the programme you're well supported, with tips and advice on nutrition, exercise and sleep.
