Foundations of Health: Why Your Health Is More Than Diet and Exercise

When I ask people what comes to mind when they think about “being healthy”, the answers are remarkably similar: eating well, exercising, perhaps getting enough sleep.

Those things are important, of course. But I’ve always found it interesting that we instinctively reduce health to a handful of habits, while at the same time knowing that our lives—and our bodies—are much more complicated than that.

A consultation rarely begins with someone telling me they feel unwell because they don’t eat enough vegetables. More often, it starts with something like, “I’ve been so tired lately,” or “I just don’t feel like myself anymore.”

As we talk, the picture becomes richer. Work has been stressful for months. A parent has become ill. Sleep has suffered. Exercise has quietly disappeared from the week. Meals have become something to squeeze in between meetings. Friends haven’t been seen for ages. Before long, we’re no longer talking about one symptom or one habit. We’re talking about a person trying to keep many parts of life moving at the same time.

That is probably one of the biggest lessons general practice has taught me: people are wonderfully complex. Health is too.

The more I learned about lifestyle medicine, the more I realised that this complexity isn’t something we should try to simplify away. It’s something we need to make room for. Our bodies don’t separate nutrition from sleep, movement from stress, or emotions from relationships. We do that because it makes these things easier to study and talk about. The body simply responds to everything that is happening, all at once.

I sometimes think we’ve become very good at zooming in, but not always as good at zooming back out again.

Medicine has benefited enormously from specialisation. We have cardiologists, neurologists, endocrinologists, pulmonologists and many other specialists, each with knowledge that a generalist could never hold in the same depth. We need that expertise. But if you asked the body where cardiology ends and endocrinology begins, it wouldn’t know what you meant.

A poor night’s sleep can change appetite and blood sugar regulation. Chronic stress affects the immune system. Loneliness influences physical health. Regular movement can affect mood, metabolism and sleep at the same time.

A few years ago, I started looking for a way to visualise this. Not because the world particularly needed another health model, but because I noticed how quickly conversations about health became fragmented. We jump from diets to supplements, from exercise to mindfulness, and from hormones to gut health as though these are separate conversations. Usually, they aren’t.

That is how this compass came about.

I eventually settled on seven foundations. Taken together, they cover many of the areas in which our health is shaped.

The first foundation is Fuel. Fuel is everything the body takes in to keep functioning: food, water and air. Food provides energy and building materials, water allows countless processes to take place, and breathing brings in the oxygen our cells depend on. I chose the word Fuel rather than nutrition because eating is only one part of this constant exchange with the world around us.

The second foundation is Act. Act includes movement, but it is broader than exercise. We act when we walk, work, play, create, explore, build and interact with our surroundings. Walking the dog, tending a garden, renovating a home, playing an instrument or chasing children around a park all require us to use our bodies and abilities. We are not made only to take things in and recover. We also need to participate in the world.

Then comes Recover. The body depends on periods of rest and repair, yet recovery is often what gets pushed aside first when life becomes busy. Sleep is central to it, but recovery also happens in quieter moments during the day when we are not constantly working, producing, solving problems or responding to the next notification. Being inactive is not always the same as recovering either. An evening spent exhausted in front of a screen may contain very little real rest.

The fourth foundation is Think & Feel. Thoughts and emotions are not separate from the body. Stress changes our heart rate, breathing, muscle tension, digestion and behaviour. How we interpret what happens also shapes how we experience it and what we do next. Think & Feel is about that inner world: our emotions, beliefs, expectations, attention and the stories through which we understand ourselves and our lives.

The fifth foundation is Connect. Humans have always depended on one another. Relationships give us belonging, support, touch, laughter, perspective and the experience of being known. The absence of meaningful connection affects more than how we feel emotionally; loneliness is also linked to physical health. Connection includes close relationships, but also family, friendship, community and the smaller interactions through which we remain part of the world around us.

The sixth foundation is Grow. We continue changing throughout life, whether we intend to or not. Grow is about our ability to learn, adapt, develop and find meaning in what we are doing. It may involve recovering abilities after an illness, learning a new skill, changing our mind or finding a different way forward when an old way of living no longer works. Our health depends partly on our capacity to respond when our bodies or circumstances change.

Finally, there's Environment. Environment includes the physical and social conditions in which health happens: the food available to us, the air we breathe, noise and light, access to nature, finances, working conditions and the neighbourhoods in which we live. These surroundings shape what is easy, difficult or practically impossible long before willpower enters the picture. Health advice that ignores them misses a large part of reality.

Separating these foundations helps us look at them, but in daily life they constantly overlap.

Take tiredness, one of the most common reasons people come to see me. We can ask whether someone is sleeping enough, but that is only the beginning. Are they eating regularly? Do they spend most of the day sitting? Are they carrying constant mental pressure? Do they have any time in which nothing is expected of them? Have they become isolated? Is noise waking them at night? Sometimes there is a medical cause that needs investigation. Often several things are happening at once.

The compass doesn’t immediately give us the answer, but it stops us from assuming there must be only one.

The same overlap works in the other direction. Better sleep may make preparing a proper meal feel manageable again. Movement can improve sleep. Time outdoors may reduce stress. Supportive relationships can make difficult changes easier to sustain. A small shift in one area sometimes creates space elsewhere.

That is also why the image in the middle of the compass is a path. Health is not a destination that we either reach or fail to reach. It changes as our bodies, circumstances and priorities change. Sometimes we have the energy and space to pay attention to it. At other times, getting through the week is already enough. We may move forward in one area while struggling in another.

I don’t expect anyone to work on all seven foundations at once. The compass is there to help us notice what may be missing from the conversation. When someone feels tired, unwell or unlike themselves, the answer may involve food or exercise. It may also involve recovery, grief, loneliness, a demanding environment or a life that has left very little room for anything beyond coping.

That is what I want to explore through The Health Shift: how all these different parts of health fit together, and what that might mean in the ordinary, often rather messy circumstances of our own lives.
