Your Identity Drives Your Behaviour: Become Someone Who Values Their Health

Most of us approach health by focusing on what we want to achieve.

“I want to lose weight.”

“I want to get fitter.”

“I want to eat better.”

“I want to have more energy.”

There’s nothing wrong with having a goal. Goals can give us direction and something meaningful to work towards.

But there’s another question we don’t ask nearly as often:

Who do I need to become?

Because there’s a difference between constantly trying to do healthy things and beginning to see yourself as someone who values their health.

The connection between identity and behaviour change is important: when healthy choices begin to feel consistent with the person you believe yourself to be, they can become easier to repeat.

If you repeatedly tell yourself:

“I’m unhealthy.”

“I have no willpower.”

“I never stick to anything.”

those statements can become more than passing thoughts.

They can become part of your identity.

And once something feels like part of who you are, behaving differently can become much harder.

But identity isn’t fixed.

Every choice you make can provide a small piece of evidence about the person you’re becoming.

In the previous article in our Body Image series, we explored why being harder on yourself doesn’t necessarily create lasting change, and how acceptance can provide a healthier starting point.

Now we’re going to take the next step.

Instead of asking only:

“What result do I want?”

we’re going to ask:

“What kind of person am I becoming?”

What You’ll Learn

By the end of this article you’ll learn:

✔ How the way you see yourself can influence your everyday behaviour.

✔ Why identity can be an important part of creating lasting habits.

✔ How small choices can provide evidence for a new identity.

✔ Why healthy choices are more sustainable when they’re connected to your own values.

✔ How to begin making decisions from self-respect rather than criticism.

Identity and Behaviour Change: The Stories We Tell About Ourselves

We all carry stories about the kind of person we are.

Some are helpful:

“I’m reliable.”

“I’m someone who looks after my family.”

“I’m determined.”

Others can quietly hold us back:

“I’ve never been sporty.”

“I’m terrible with food.”

“I’m just not disciplined.”

“I always give up.”

The problem is that these statements don’t simply describe our past.

They can begin influencing what we expect from our future.

Imagine you’ve told yourself for years:

“I’m someone who never sticks to exercise.”

You start a new routine.

For three weeks, things go well.

Then you miss a few sessions.

What does your mind say?

“See? I knew this would happen.”

The missed sessions become evidence for the old identity.

But there’s another way to interpret exactly the same situation:

“I’ve exercised consistently for three weeks. I’ve had a difficult few days, and now I’m going to get back to it.”

Same situation.

Very different story.

And the story matters.

The Science (Made Simple)

Psychological research into identity-based motivation suggests that our sense of identity can influence which behaviours feel relevant and natural to us.

Put simply:

We’re often drawn towards behaviours that feel consistent with the person we believe ourselves to be.

If you think of yourself as someone who enjoys being active, going for a walk doesn’t necessarily feel like completing a task from a health plan.

It’s simply something you do.

If you see yourself as someone who values sleep, going to bed earlier isn’t punishment.

It’s consistent with what’s important to you.

This doesn’t mean you simply announce:

“I’m a healthy person”

and suddenly every behaviour changes.

Identity develops through experience.

You begin giving yourself evidence.

One decision at a time.

Every Choice Is Evidence

Imagine you’d like to become someone who takes better care of their health.

Today you go for a 20-minute walk.

That’s evidence.

Tomorrow you prepare lunch rather than buying something because you’re rushed.

More evidence.

You turn your phone off a little earlier and get to bed on time.

More evidence.

None of those choices transforms your health overnight.

But each one reinforces a message:

“I’m someone who looks after myself.”

Then perhaps Thursday doesn’t go well.

You’re exhausted.

Dinner isn’t what you’d planned.

You don’t exercise.

Does that erase the evidence from Monday, Tuesday and Wednesday?

Of course not.

You’re not trying to prove that you’re perfect.

You’re gradually changing the balance of evidence.

That’s a very different approach from waiting until you’ve achieved a goal before allowing yourself a new identity.

You don’t need to lose the weight before becoming someone who values their health.

You practise becoming that person while you’re getting there.

Stop Chasing the Result

Many health goals focus almost entirely on outcomes.

A number on the scales.

A clothes size.

A race time.

A blood result.

There’s nothing inherently wrong with those goals.

The difficulty is that outcomes aren’t always completely within our control, and they often take time.

Behaviour gives us something more immediate to work with.

Instead of asking:

“Can I lose two stone?”

try:

“What would someone who values their health do next?”

Instead of:

“Can I get fit?”

ask:

“What would an active person do today?”

Instead of:

“Can I sort my diet out?”

ask:

“What would someone who wants to nourish their body choose for their next meal?”

Notice the word next.

Not forever.

Not every day for the rest of your life.

Just next.

That’s how identity begins to shift.

Be Careful With the “Healthiest Version of You”

There’s an important distinction here.

Asking:

“What would the healthiest version of me choose?”

can be useful.

But it shouldn’t become another demand for perfection.

The healthiest version of you doesn’t necessarily choose salad at every meal, exercise every day and go to bed at 9pm.

Sometimes the healthy choice is movement.

Sometimes it’s rest.

Sometimes it’s cooking a nourishing meal.

Sometimes it’s enjoying a meal with your family without analysing every ingredient.

Sometimes it’s saying yes.

Sometimes it’s setting a boundary and saying no.

Health exists within a life.

The aim isn’t to construct a perfect imaginary version of yourself and then criticise yourself whenever you don’t live up to it.

It’s to understand what you value and allow those values to guide more of your decisions.

What Do You Actually Value?

This brings us to an important question.

Why do you want to be healthier?

It’s easy to answer:

“To lose weight.”

But go a little deeper.

Why does that matter?

Perhaps you want more energy to play with your children or grandchildren.

Maybe you want to feel physically capable as you get older.

Perhaps you want to reduce your risk of future illness.

Maybe you want greater independence.

Better sleep.

More confidence.

More freedom.

Or simply to feel better day to day.

Those reasons matter because they’re connected to your life, rather than somebody else’s expectations.

And that’s where motivation can become much more meaningful.

A Lesson I’ve Learned Through Coaching

People often assume they need more motivation.

But motivation naturally rises and falls.

You can feel incredibly motivated on Sunday evening and completely differently by Wednesday afternoon.

That’s why relying entirely on motivation makes behaviour change difficult.

A more useful question can be:

“What matters to me?”

If somebody tells me they want to exercise more, I’m interested in why.

If the answer is:

“Because I know I should,”

there often isn’t much to hold onto when motivation disappears.

But perhaps exercise means remaining mobile enough to travel when they’re older.

Perhaps improving their health means having energy for their children.

Perhaps eating differently means avoiding the afternoon crash that makes every working day difficult.

Now the behaviour has meaning.

We’re no longer following a rule.

We’re acting in a way that’s consistent with something we value.

That’s a much stronger foundation for change.

Identity Doesn’t Have to Be Earned

There’s another trap worth recognising.

You might think:

“I can’t call myself an active person. I only walk twice a week.”

Why not?

An active identity doesn’t require you to run marathons.

“I can’t say I eat healthily. I still eat chocolate.”

Eating healthily doesn’t require dietary perfection.

“I can’t say I look after myself. I still have bad weeks.”

Looking after yourself doesn’t require never struggling.

Be careful not to create an entry requirement for the identity you’re trying to build.

You’re not claiming perfection.

You’re choosing a direction.

Instead of:

“I am perfectly healthy.”

try:

“I’m becoming someone who takes care of their health.”

That leaves room for growth.

Your Past Doesn’t Have to Become Your Identity

Perhaps you’ve tried to change before.

Maybe many times.

That history is real.

But there’s a difference between saying:

“I’ve struggled to maintain this habit in the past.”

and:

“I’m someone who can’t stick to anything.”

One describes experience.

The other turns experience into identity.

Your past can teach you something without defining what happens next.

If previous diets were too restrictive, that’s information.

If gym memberships never lasted, that’s information.

If elaborate routines collapsed when work became busy, that’s information.

You don’t need to conclude:

“I always fail.”

You can ask:

“What have these experiences taught me about what I actually need?”

That’s awareness.

And awareness gives you the opportunity to choose differently.

Take a Moment…

Complete this sentence:

“I’m becoming someone who…”

Try not to make it about appearance.

Instead think about the relationship you’d like to have with your health.

Perhaps:

“I’m becoming someone who values their energy.”

“I’m becoming someone who moves regularly.”

“I’m becoming someone who prioritises sleep.”

“I’m becoming someone who nourishes their body.”

“I’m becoming someone who listens when their body needs rest.”

Then ask:

What would provide one small piece of evidence for that identity today?

Not ten things.

One.

One Small Step Today

Before your next health-related decision, pause for a few seconds.

Ask:

“What would someone who values their health do next?”

Then add a second question:

“Is that choice coming from care or criticism?”

Those two questions bring this week’s ideas together.

You’re considering the person you’re becoming.

And you’re considering the relationship you want to have with yourself while becoming them.

Your answer doesn’t need to be perfect.

Sometimes you’ll still choose differently.

That’s okay.

You’re not trying to win every vote.

You’re trying to gradually cast more votes for the person you want to become.

The Trust Health Coaching Takeaway

Lasting health isn’t only about achieving a result.

It’s also about the person you’re becoming while you pursue it.

If your health journey constantly reinforces:

“I’m not good enough.”

“My body is a problem.”

“I need to punish myself into changing.”

even achieving the result may not create the relationship with your body you expected.

There’s another way.

You can begin practising the identity now.

I’m someone who values my health.

I’m someone who deserves looking after.

I’m someone learning to make choices that support my wellbeing.

Then let your actions provide the evidence.

A walk.

A nourishing meal.

An earlier night.

A boundary.

A moment of rest.

One choice doesn’t define you.

But repeated choices can gradually change the story you tell about yourself.

And perhaps the most important shift is this:

You don’t look after yourself because you’ve finally become worthy of care.

You look after yourself because you’re worthy of care now.

Awareness is the first step towards meaningful change.
