How I can help
Who is it for? For you, quite simply
You don’t need to be sporty to book a consultation: most of my patients come for their health, their energy or their weight.
Everyday health
Fatigue, digestion, weight, cholesterol, blood sugar, pregnancy: a way of eating that suits you, without counting calories.
Functional nutrition
Bloating, IBS, PCOS, (peri)menopause, inflammation, fatigue: we link your symptoms to your blood test results.
Getting back in shape
Private or small-group coaching in my studio: get active again, safely and at your own pace.
Sport and performance
Running, triathlon, trail, cycling: training and race nutrition, plus training plans tracked on Nolio.
Connected data
Oura, Garmin, Apple Watch, glucose monitor: we combine your data with how you feel for tailored advice.
Companies
Performance coaching for executives and self-employed professionals, plus nutrition talks and workshops in the workplace.
My approach
No diets, just lasting results
Glycaemic index
Stabilise your blood sugar to better manage hunger, energy and weight.
Connected health data
Sleep, HRV, blood sugar: your wearables working for your plate.
What my own data has taught me
250 nights analysed with my Oura ring
Before offering it to you, I tried it on myself: 250 days of sleep, recovery and training, from my preparation for Ironman Taiwan to today. A few lessons learned:
+ 1 h 20
more sleep when I go to bed before 10.30 pm rather than after 11.30 pm
+ 26 min
of REM sleep, the kind that does the most for my recovery
Just 1
real rest day every 25 days… my next project, and it’s also a question of what’s on my plate
What really matters for me isn’t always the metric everyone looks at. For you, it may be a different one. That’s exactly what we look for together in a consultation.
