For yourself — and together. Because lifestyle makes an impact.

At Ancora, we understand that change isn’t always easy. Especially when you’re in the middle of a journey full of hope, tension, and uncertainty. That’s why you’re not doing this alone. 
Support along the way:

With the easy-to-use Ancora app, two dedicated coaches, and a group of like-minded women, you’ll work step by step on nutrition, physical activity, sleep, and stress. In a way that fits your life — from home and fully covered by your health insurer. 

Stronger together:

Want to participate with your partner? Absolutely! This is possible if they meet the criteria or choose to join only certain elements. Working on your lifestyle together not only strengthens your motivation but also leads to more understanding and support at home, which increases the chance of lasting change. 

Support that fits:

You deserve support that matches your pace, with attention to both body and mind. That’s why we combine medical expertise with personal coaching, digital tools, and group sessions with women (and partners) who are in the same special phase as you. 

More chance of a natural pregnancy 

1 out of 2 participants achieve between 5-20% weight loss resulting in reduced blood pressure and significantly lower stress levels.
Body and cycle in balance
Bring calm to your body and support hormonal balance — crucial for increasing your chance of a natural pregnancy. 
Nourish instead of diet
Discover how your eating habits affect fertility. Give your body the right fuel to feel more balanced and rested. 
More energy and resilience
Learn to cope better with stress, fatigue, and hormonal fluctuations, and feel stronger inside and out. 
Healthy weight, lasting results
Even a small weight loss can improve fertility and give your baby a healthier start. We help you lose weight responsibly — and keep it off.

Lifestyle and fertility

A healthy lifestyle plays a bigger role in fertility than often assumed.

Research shows that factors like nutrition, physical activity, weight, stress, and sleep directly influence your chances of getting pregnant. Our approach aligns with fertility treatments such as IVF or IUI, or helps increase the chance of natural conception. 

Even a 5 to 10 percent weight loss can lead to a more regular menstrual cycle, restored ovulation, and increased chances of pregnancy. Reducing stress and stabilizing your blood sugar levels also play an important role.

“A healthy lifestyle significantly increases the chances of a natural pregnancy and contributes to a healthier pregnancy overall. In a previous pilot, we saw that a large proportion of participants eventually became pregnant. This motivates us to make lifestyle support a structural part of fertility care.”  

Drs. Jolijn Huisman, Expert in fertility and lifestyle, with eight years of experience as a fertility physician

How does SLIMMER work?

1. Start

The program begins with a conversation with your GP or practice nurse. Together, you will assess whether participation in this lifestyle program is appropriate for your situation — and if your partner wants to join, for theirs too. Many GPs can register you directly through their referral platform. For full participation, both you and your partner need your own referral. As soon as we receive your referral letters, we will create an online account for both of you. After that, you each fill out an intake form and schedule your first coaching session.

2. Do

You’ll receive personal coaching and online group sessions where you work step by step on nutrition, movement, sleep, stress, and hormonal balance. All factors that influence fertility.

You follow the program entirely online, via the Ancora Health app. There you’ll receive tips, assignments, and direct contact with your coach — tailored to your body, goals, and daily life.

If your partner is not eligible or doesn’t want to follow the full program, they can still join individual sessions like group or coaching sessions. A referral is not required for this.

3. Live Healthy

Together with a group of like-minded participants, you’ll continue to work on maintaining your healthy routines — even in the long term. You’ll motivate and support each other, especially during a time that can feel uncertain.

In the Ancora Health app, you’ll track your progress and see improvements in your energy, or weight, and continue to get new inspiration. This way, you keep building a healthier body that’s ready for the next step.

Hear from our users

The choice for SLIMMER Online was quite easy for me, because the physical GLI only took place during the day and that did not fit into my work schedule. The digital program gave me the flexibility to work on my goals without disrupting my work.

Richard, Slimmer patient

I see participants taking steps every week and hear the gratitude in their stories. That gives them a lot of energy and motivation to offer them that little bit of support every time.

Jordy Oud, online SMARTER lifestyle coach at Ancora Health

The digital program really enhances accessibility, allowing my participants to progress flexibly while enabling me to provide meaningful support from anywhere.
