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.

After 40, losing weight feels like a lost cause

A slower metabolism, shifting hormones, a life that keeps going. It is not your fault. Support and medication can be the nudge that finally makes it work, without a strict diet.

For us, the focus is on balance and sustainable weight loss, not on strict dieting.

“Over the past few years I’ve helped 1,000+ people lose weight, often alongside weight-loss medication.

I’ve worked at several clinics and seen first-hand what works and what doesn’t.

Together with doctors and specialists, we built Lean Clinic to make medical support digital and affordable.”
