About Len De Nys

Experience and expertise

Healthy Ageing education

I want to create awareness about the science of targeted diet- and lifestyle interventions to increase healthspan. That is why I founded the 'House of Lifestyle', a place for education and consultancy for healthy ageing and longevity. I'm always in for a talk or a lecture about diet-and lifestyle strategies for health and well-being.

Personal story

Through personal and clinical experiences, I discovered the effectiveness of healthy lifestyle strategies in tackling chronic health conditions. Through my in-depth knowledge and passion about the science of Lifestyle Medicine, I hope to inspire professionals and patients on their health journey.


I have a Master's in Rehabilitation Sciences and Physiotherapy and conducting a PhD study about Stress, Healthy Ageing en Physical Exercise at the University of Stirling of Scotland. My clinical expertise is in stress and sleep management and auto-immune conditions.

About my courses

Translating the latest relevant scientific knowledge about healthy ageing and diet-and lifestyle interventions into clinical practice.

Creating healthy and long-lasting habits

Providing the right information doesn't always result in long-lasting healthy behaviours. You will get insights on how to create healthy habits to change your behaviour to sustain your health.

Theoretical background and practical tools

I gather novel and innovative scientific knowledge about diet- and lifestyle interventions in the Healthy Ageing field. I aim to provide tips and tricks applicable in clinical practice.

Topics of the courses and special expertise

Currently, the focus of my courses is in the area of diet- and lifestyle interventions for (1) Healthy Ageing, (2) Stress and sleep management or (3) Auto-Immunity.

The effects of physical activity on cortisol and sleep

Managing stress and having good quality sleep are essential for health, and both factors seem to be affected by physical activity. Although there is an established bidirectional relationship between stress and sleep, remarkably few studies have been designed to examine the effects of physical activity on cortisol, a biomarker for stress, and sleep. Therefore, we conducted a systematic review.

Systematic review and meta-analysis

Exercise can reduce stress and improve sleep – particularly for women with breast cancer

An article that explains the research we conducted about stress and sleep for the lay public. With over 5000 reads in two months, we might conclude that many people suffer from stress and sleep complaints.

Minder stress en betere nachtrust dankzij lichaamsbeweing

Blogpost in EOS

Stress en slaap zijn verbonden en kunnen positief beïnvloed worden door lichaamsbeweging. Welk soort beweging heeft de beste impact op stress en slaap? Wat is het beste tijdstip om aan lichaamsbeweging te doen? PhD-onderzoeker Len De Nys onderzocht het en schreef er deze blog over.

The effects of physical activity on cortisol and DHEA(S) in older adults

Systematic review and meta-analysis

Age-related changes affect the ratio between two steroid hormones of the hypothalamic-pituitary-adrenal axis, cortisol and dehydroepiandrosterone (sulfate) (DHEA[S]). Physical activity (PA) may buffer the effects of chronic stress and counteract the aging decline of DHEA(S). Therefore, a systematic review was conducted to understand how PA influences physiological markers of cortisol and/or DHEA(S) and whether there is a difference in observational associations or experimental effects in older adults aged 65 years and older.
