Your journey towards lasting and sustainable weight loss

Get started

Free consultation

Start by answering a few questions about your health. Then download the Yazen app, where you’ll connect with a nurse who will guide you through a questionnaire about your current situation and help you take the next step. This step is free of charge.

A warm welcome to Yazen – we are here for you and take care of the comprehensive approach!

Health check-up

We offer a comprehensive health check, including blood tests to assess hormones, metabolic markers, and vitamins. A standard test costs £119. The blood test can be taken at home or at a health check facility. If you have had a health check with a blood test within the last 12 months, you can submit those results instead.

Personalised treatment plan

Your doctor will review your consultation responses and test results, and then you and your doctor will agree on a treatment plan that includes medication and lifestyle changes tailored to your needs, lifestyle, and goals. Throughout your weight journey, the doctor will be responsible for your medical treatment and will adjust your medication when necessary. The team supports and guides you throughout the treatment, ensuring that side effects are minimised.

Tailored treatment plan and support

Based on your individually tailored medication and treatment plan, you will gradually make lifestyle changes to reach your weight goal. You will learn how your body responds to the changes you make, and with the support of your medication and team, you will create new healthy habits. We are here to answer your questions, provide inspiration, and – based on your circumstances – find what works best for you.

* Yazen's subscription starts at just £69 per month, offering a cost-effective pathway to sustainable weight management. We partner with a leading online pharmacy, ensuring access to medications at competitive prices. For example, you would typically pay between £50 and £100 per month for your medications, making the total cost for the service and medication range between £125 and £200 per month. This comprehensive solution allows you to collaboratively determine the dosage with your doctor, tailored to your individual needs, ensuring optimal care and value.

Expert guidance

Together with your YazenCoach, you will set goals and identify what helps you succeed – and what may be holding you back. With the support of your team, you will work towards improving your health and wellbeing. You will still have contact with your doctor, but it’s your YazenCoach you will be in closest contact with. If needed, your coach can also guide you to further support from a psychologist, dietitian, or physiotherapist.

In the app, you’ll find everything you need for your weight loss journey, always just a tap away. We respond to your questions within 24 hours. In our Community, you can connect with other patients and experts for more inspiration and support.

Build lasting habits

You will create new healthy habits and, together with your doctor, fine-tune your medication. Through our modular educational programme, Yazen Commit, you will receive daily lessons which will guide, inspire and support you to make the behavioural changes needed to lose weight and maintain a healthier weight. The Yazen Model takes a holistic approach to weight loss and health, focusing on diet, physical activity, recovery, and well-being, both physically and mentally. 

The Change phase lasts between 12 to 24 months, depending on your progress. You and your doctor will decide the right time to transition to the Clarity phase, but it will never be more than 24 months.

Give yourself the best conditions to create new habits for your health and empower yourself, inside and out!

Maintenance dose or gradual reduction?

When you reach your target weight, you and your doctor will discuss reducing your medication to a maintenance dose. If you wish to try stopping the medication, you will receive support from your YazenCoach and doctor to ensure the process goes as smoothly as possible.

Live life with newfound strength

This is an exciting time. You’ve developed healthy habits and learned effective tools to help you stick to them, even in more challenging situations. Your journey continues now, towards better health and wellbeing, and maintaining your new weight.

After 12 to 24 months, you and your treatment team will discuss whether it's time to reduce your medication to a maintenance dose. If you want to try stopping the medication entirely, you will receive support from your YazenCoach and doctor to ensure the process goes as smoothly as possible.

A new pricing model for the Clarity phase will be launched in 2025. Stay tuned for more details!

Real people. Real results.

Thanks to Yazen, I’ve started 2025 two sizes down, feeling healthier, happier, and finally free from the never-ending battle with dieting.

Gemma Collins is a British television personality, actress, and businesswoman, best known for her role on the reality series, The Only Way Is Essex.  Gemma started 2025 two sizes down, after just two months using Yazen's Weight Loss app and medication. “It has absolutely changed my life,” she says.

Having tried every diet, Gemma has finally found something she can actually lose weight on. She feels healthier and happier, without that constant noise in her head “You need to eat,  you need to eat.” 

Gemma is keen to share this approach with anyone that suffered their whole life like her - being bullied all her life by the media for being overweight. She will finally be able to live her best life and be free from the upset, stress and turmoil that comes with constantly trying to lose excess weight.

"I really can’t wait to get stuck back in hiking. Mount Kilimanjaro, here I come!"

Alex, a lifelong Londoner, shares her journey with a weight loss programme combining medication and personalised coaching. After struggling with weight gain due to mental health medication, she tried various diets with little success. Thanks to daily support from her YazenCoach and a more balanced approach to food, Alex is finally on the right path. She’s now focused on returning to more challenging hikes, with plans to tackle Mount Kilimanjaro.

"With Yazen, I’ve received a level of support I’ve never felt before in anything I’ve gone through in my life."

Erica, a London-based photographer with an active career, started her weight loss journey after discovering she had high cholesterol. Despite trying various diets, she struggled to lose the 20-30 lbs she had gained over the years. After joining Yazen, she received comprehensive support, including medication, diet guidance, exercise tips, and emotional support from a dedicated team of professionals. She’s also adopted a healthier lifestyle, incorporating better food choices and regular exercise into her routine.
