Sugar-free November · 2–29 November

Four weeks less sugar, guided and together.

Cutting sugar overnight rarely sticks. So we do it in steps, with nutrition therapist Shakhnoza Cetintas guiding the group, and a WhatsApp chat where everyone checks in every evening.

You join for €29. That includes the whole challenge and your place at the club meeting on 29 November, where we finish together. Sign up by Sunday 1 November; we start on Monday 2 November.

  • Start
    Sugar self-check

    Eight quick questions, so you know how strong your pull to sugar is and how gently to start.

  • Weeks 1–2
    Step by step

    We gradually reduce sugar, find swaps that work for you, and cut down slowly. No cold turkey.

  • Weeks 3–4
    As sugar-free as you can

    Maximum cut: no added sugar, honey and syrups too. This is when Sweet Shield, kindly provided by Nosu, helps most.

  • Every day
    Check in in a separate chat

    A short daily report in our challenge chat: how it went, your cravings and energy out of 10. Shakhnoza shares tips every week.

  • Optional
    Test before and after

    Want to see it in numbers? Do a fasting blood test before 2 November and again on 27–30 November: triglycerides and glucose, ideally plus fasting insulin. Same lab, same morning time, no alcohol or hard workout the day before. HbA1c moves slowly, so test it now and again at the end of January.

  • 29 Nov
    The finish line

    We meet at Moychay, share results and ask Shakhnoza everything.

Monthly meeting · 29 November

How to eat less sugar

Why does sugar pull so hard, what happens in your body when you cut it, and how much is hiding in the "healthy" food in your kitchen? Shakhnoza walks us through it, and then we put it to the test with a live quiz. It's also the finish line of Sugar-free November, so expect real stories from four weeks without sugar.

Your guide in November

Shakhnoza Cetintas

Nutrition Therapist in training · CNM, UK

How a meeting goes

A small room, one subject, and people who get it.

You'll actually talk to people, and the speaker can answer your question rather than a general one.

No pitching and no business cards. Just a subject worth understanding and people who find it as interesting as you do. Come back next month and the same faces will be here.

  • 12:30
    Tea and arrivals

    Get yourself a drink at the bar and settle in.

  • 12:40
    Speed-meet

    Two short conversations with new faces.

  • 12:50
    The talk and a sugar quiz

    How many sugar cubes are in your granola?

  • 13:20
    Your questions

    The real ones. Then a group photo, and stay as long as you like.

How our first meeting went

Know your numbers, with Vincent Schot of Biowell

A full room at Moychay, a talk on what your bloodwork actually tells you, and a lot of very good questions. Thank you to everyone who came. The next meeting is on Sunday 29 November.

Anna Leona, founder of Longevity Club Amsterdam
Why this exists
I only found out because I looked.

At some point I was tired all the time and my hair was falling out. I put it down to stress, the way everyone does. Then I did something ordinary: I got my bloodwork done. My ferritin was low. Low enough to explain months of feeling flat and wondering what was wrong with me.

Nobody had told me any of that. I only knew because I looked.

Two years ago my father died of cancer. He had never checked anything. There were signs, and they went unlooked at. That is the reason I stopped waiting to feel unwell before paying attention.

Here, if you feel more or less fine, looking after your health is mostly something you have to go and do yourself. So I did. And I found out how quiet that is: reading late at night, making decisions alone, with no one to ask whether any of it makes sense.

That is what these mornings are. A room of people doing the same thing, and someone who genuinely knows the subject to answer the questions we all arrive with. I run Moychay, a tea house in Amsterdam. It is where we meet. Tea turns out to be a very good reason to sit with people for a morning.

If that sounds familiar, come on the 29th. You will know by the end of the morning whether it is your kind of room.

Who this is for

For people who take it seriously and want the company.

This isn't a clinic, a gym, or a networking night. If that's what you're after, you'll be disappointed, and we'd rather say so now.
  • You've read more about health at midnight than you'd like to admit, and had nobody to ask about any of it.
  • You moved to Amsterdam in the last few years and your circle is still mostly work.
  • You'd rather talk over tea or a walk than over drinks.
  • You'd like to get ahead of things rather than wait for something to go wrong.
  • You're not looking for one more event, you're looking for something that keeps happening.

Where this is going

The last Sunday of every month.

We meet on the last Sunday of every month, each time with a different subject and a different speaker. In December we run the Longevity Advent and meet online on Sunday 27 December; we're back at Moychay on Sunday 31 January.

The point isn't the talks. It's that the same people come back, and by the third month the room knows your name.

Can't make the 29th? Join our WhatsApp group and you'll hear about the next one first.

Questions

Good to know

How much is it?

A ticket for the monthly meeting is €15. Sugar-free November is €29 and includes the 29 November meeting.

How does Sugar-free November work?

From 2 to 29 November, in a WhatsApp group guided by nutrition therapist Shakhnoza Cetintas. A short self-check at the start, two weeks of gradually reducing sugar and finding swaps, two weeks of cutting it out as far as you can, and a daily report in a separate challenge chat. We finish together at the meeting on 29 November.

Do I need to know anything about health already?

Not at all. Most people arrive with questions rather than answers. Curiosity is the only requirement.

Will I know anyone there?

Probably not at first. That's rather the point: we start with a short speed-meet, and people talk.

How long is the meeting?

12:30 to 13:30. The tea house is open all day, and most people stay on.

Is everything in English?

Yes, from start to finish.

Is this medical advice?

No. We're a community, not a clinic. Nothing here is medical advice, and we don't diagnose or treat. If you have diabetes, take medication, are pregnant, or have a history of eating disorders, please check with your doctor before joining the challenge.

What if I can't make this one?

Join our WhatsApp group and you'll hear about the next date first. We meet on the last Sunday of every month.

See you on the 29th?

A small room, one subject, and people who get it. Come and see.

We're a community, not a clinic. Nothing on this page is medical advice, and we don't diagnose or treat.
