Beyond BMI – redefining how we understand obesity
On World Obesity Day, Yazen brought together leading voices in healthcare to challenge outdated metrics and highlight how body composition is redefining the way we assess and treat obesity.

Beyond BMI – redefining how we understand obesity
On World Obesity Day, Yazen hosted a special webinar exploring one of the most pressing topics in modern healthcare: why BMI alone is not enough to understand or treat obesity – and how a deeper look at body composition can lead to better outcomes for patients.In this engaging and informative session, Martin Carlsson, Chief Medical Officer at Yazen, and Antoine Robiliard, VP of Health Solutions at Withings, take a closer look at what really matters when it comes to assessing health risks and tracking progress in obesity care.Together, they discuss:
- The major limitations of BMI and how it can misclassify individuals
- Why fat distribution, visceral fat, and muscle mass are stronger indicators of health
- The role of body composition in the new Lancet definitions of clinical and pre-clinical obesity
- How smart devices like the Withings scale support long-term behaviour change by providing actionable insights – not just numbers on a screen
The power of tracking trends over time, and how small, sustainable steps can have a big impact. You’ll also hear personal reflections from both speakers – including Magdalena Einarsen Adam, Yazen’s Event Manager and a patient herself – on the challenges, motivation, and mindset shifts involved in managing weight and health.
This webinar is ideal for healthcare professionals, patients, researchers, or anyone interested in the future of personalised obesity care.
Watch the full webinar and discover how Yazen and Withings are helping to shift the conversation beyond BMI – towards a more accurate, compassionate, and science-based approach to health.

The best diet to lose weight quickly – how to do it in a healthy way
When the goal is to lose weight quickly, it’s easy to get caught up in headlines and new trends. However, research consistently points in the same direction: the best diet for losing weight is the one you can maintain over time — one that creates a calorie deficit while still providing enough nutrients, vitamins, and minerals. When your energy intake (kcal) is lower than your energy expenditure, your weight decreases – regardless of what the diet is called (1,2).
How to reduce the risk of loose skin after weight loss
Weight loss can bring significant positive changes for both health and wellbeing. At the same time, many people experience loose skin after substantial weight loss, especially if the weight has decreased rapidly or if they have lived with overweight or obesity for a long time.
Loose skin is a natural result of changes in the skin’s elasticity as the body adjusts. By understanding how the skin is affected after weight loss and which factors influence its elasticity, you can give the skin better conditions to tighten and feel firmer again.
