Helping women 40+ feel better, more energised and more in control of their health.
Personalised health coaching to support your energy, healthy weight, sleep, nutrition and everyday wellbeing — while helping you understand what your body needs and build healthier habits that last.
WELCOME
You know you want to feel better. You’re just not quite sure where to start.
Perhaps your energy isn’t what it used to be. Your weight has become harder to manage, your sleep isn’t as good, you’re experiencing more cravings or changes in digestion, or stress seems to affect you more than it once did.
Or maybe nothing feels particularly wrong. You simply know that now you’re over 40, you want to take better care of your health and feel your best for the years ahead.
With so much conflicting advice around nutrition, hormones, fasting, supplements, exercise and longevity, it can be difficult to know what your body actually needs.
That’s where I can help.
I take the time to understand you, your lifestyle and what you want to change. Together, we focus on the foundations that can make a real difference to how you feel — nutrition, blood sugar balance, sleep, stress, movement, gut health and everyday habits.
The aim isn’t perfection or changing everything at once. It’s helping you understand what works for you and make realistic changes you can continue long after our work together.
Hi, I’m Myriam armstrong.
I’m originally from Switzerland. I met my British husband skiing — about as typical as it gets for a Swiss woman — and moved to London over 30 years ago, a city I still love and where I raised my two children.
Life, however, didn’t unfold quite as I had imagined. I lost my husband suddenly when I was 39 and had to find my way forward, emotionally and personally, while raising my family.
That experience changed the way I looked at health. At first, it wasn’t about longevity or trying to do everything perfectly. I simply began paying more attention to the things that helped me feel better — how I ate, how I moved, how I slept, how I managed stress and the small choices I made every day.
The more I learned, the more fascinated I became by how connected our health really is.
Six years ago, I decided to take that interest further and trained as a certified Holistic Health Coach with the Institute for Integrative Nutrition in New York, followed by further training in hormone health. Today, at 55, I’m continuing my studies in Nutritional Therapy at the College of Naturopathic Medicine (CNM) in London
I now bring that knowledge together with my own life experience to help women 40+ understand their health, make realistic changes and build foundations that can support them for years to come.
Because I truly believe it’s never too late to start looking after yourself differently.

ROSA, 57
More energy · Better sleep · 9kg lost over four months
“I am 57 and I had been dealing with a lack of energy and weight gain. I felt the urgency to change my way of living in order to get more energetic and lose some weight, particularly around my tummy.
The Foundations Programme gave me enough insight to reshape my habits, with very easy-to-prepare meals that I could also take to work.
The result: a lot more energy, softer skin, sleeping like a princess again and weight loss. Thank you, Myriam, for your assistance and positive approach.”
Four months later, Rose had lost a total of 9kg by continuing to apply what she learned through The Foundations Programme — and has sustained her results.
TANIA, 49
Fewer sugar cravings · More energy · Better sleep · Feeling in control again
“Before The Foundations Programme, I was constantly craving sugar. It felt like I needed something sweet after every meal and as snacks, and my energy levels were all over the place.
Myriam made it so simple and doable. The meals were satisfying and, for the first time in ages, I didn't feel deprived. Within the first week, my sugar cravings started to fade, and I noticed my mood and sleep improved too.
By the end of the programme, I'd lost a few pounds, but more importantly, I felt in control again. I've got more energy, clearer skin, and I'm not constantly thinking about food.”
SARAH, 52

My approach
My approach is practical, personalised and grounded in evidence. I believe that lasting change comes from understanding your health, focusing on the areas that matter most, and making realistic changes that work in your everyday life.
Rather than trying to change everything at once, we build the foundations step by step.
① UNDERSTAND
We start by looking at the whole picture — your current health, nutrition, energy, sleep, stress, digestion, movement, lifestyle and what you would most like to change.
Understanding where you are now helps us identify where to focus first.
② Build
Together, we introduce practical nutrition and lifestyle changes around the areas that need the most support — from blood sugar and energy to sleep, stress, gut health and everyday habits.
Everything is personalised to you and designed to fit into your life
③ Sustain
The goal is not simply to follow a plan while we work together. It is for you to understand what works for your body and develop habits you feel confident continuing on your own.
So that looking after your health becomes part of the way you live — not another programme you finish and forget.
Areas I Can Support You With
