The 6 Most Important Concepts for a Healthy Life
You can’t really talk about nutrition without acknowledging everything around it — because what’s on your plate is only ever part of the picture. Real, lasting health comes from the connection between what we eat and how we live, and from learning to nourish your own unique body rather than following someone else’s rules. These are the six concepts at the heart of how I coach — and, I think, of a healthy life you can actually enjoy.
1. Bio-individuality
Everyone is different — and that’s a good thing. There’s no single diet or wellness routine that works for everyone, and a growing body of research backs that up. What leaves one person energised can leave another flat. So rather than comparing yourself to anyone else, the real work is discovering what your body needs. When you're eating mostly whole foods and genuinely feeling good on them, the possibilities are wonderfully wide open.
2. Primary food
Real health is about far more than food. You can eat all the vegetables in the world, but if you dislike your work, feel unfulfilled in your relationships, never move your body or never make time for yourself, you’ll still feel undernourished — just not in a way a meal can fix. I call these the “primary foods”: your career, your relationships, your sense of meaning, movement and the things you’re passionate about. They feed you every bit as much as what’s on your plate.
3. Crowding out
Most diets fixate on what you must give up — which only creates a cycle of deprivation, pressure and, eventually, “failure.” I work the opposite way: by adding more good things in, rather than taking things away. As nourishing foods fill more of your plate and your day, they naturally “crowd out” the less helpful ones — no white-knuckling required. Over time, your tastes shift, your cravings settle, and balance starts to feel much easier. (You can read more about that gentler, no-deprivation approach here.)
4. Be your own kind of healthy
Have you ever quietly disagreed with how everyone around you approaches health — but said nothing, not wanting to stand out? Most of us are wired to “fit in.” But your wellbeing is yours. I’d much rather you do the things that genuinely make you feel good, even if they look a little different from the crowd. Being authentic isn’t only more comfortable in the long run — it tends to quietly inspire the people around you, too.
5. The 90/10 balance
Here’s something else that’s good for you: pleasure. I believe in balance, and balance means letting go sometimes so you can actually enjoy your life. The 90/10 idea is a simple reminder that if you eat well and look after yourself around 90% of the time, your body can happily take a slice of cake or a glass of wine the other 10%. The goal of healthy living was never to be so strict that you squeeze the joy out of it — you deserve to relax and savour the moment.
6. Eat real food
And, last but not least, the foundation: eat whole, minimally processed food. Eat with the seasons, and enjoy variety — different colours and textures, plenty of vegetables and fruit, wholegrains, a range of proteins, legumes, nuts and seeds. Whether you’re omnivore, vegetarian, vegan, Mediterranean, gluten-free or any mix of these matters far less than one thing: learning to truly listen to your body, and giving it more or less depending on what makes you feel your best.
Common questions
What is bio-individuality? It’s the idea that there’s no one-size-fits-all diet — the right way of eating is the one that suits your body, life and preferences. It’s the starting point of everything I do.
Do I have to give up the foods I love to be healthy? No. Rather than restricting, I focus on “crowding out” — adding more good things so the rest naturally takes up less space. The 90/10 balance leaves plenty of room for the foods you enjoy.
This is just the tip of the iceberg. If it resonates and you’d like to explore what it looks like for you, you’re welcome to book a chat.
