Why You Feel Like Two Different People Around Food: How Parts Therapy Can Transform Your Relationship with Food

Have you ever found yourself thinking…

"Who even am I?"

On Monday you're meal prepping, drinking two litres of water, smashing your workouts and feeling completely committed to your health.

By Friday you're eating Tim Tams on the couch, wondering where all your motivation disappeared to.

You promise yourself you'll "start again Monday."

Again.

If this sounds familiar, I want to reassure you of something.

You're not broken.

You're not lazy.

And you probably don't need more willpower.

One of the therapeutic approaches I use inside Weight Loss Mindset Therapy has completely changed the way I understand why people struggle to create lasting change. It's called Parts Therapy, and once you understand it, you'll never look at self-sabotage in quite the same way again.

What is Parts Therapy?

Parts Therapy is based on a beautifully simple idea:

We all have different parts of ourselves that step forward at different moments in our lives.

I specifically trained in Resource Therapy, although you may have heard of Internal Family Systems (IFS), which has become increasingly popular in recent years. There are also similarities with Gestalt Therapy, particularly its concept of the "Top Dog" and the "Underdog," and even personality frameworks and archetypes explore similar ideas.

While each approach has its own methods, they all recognise something incredibly important:

Human beings aren't as psychologically simple as we often believe.

We're not one consistent personality.

We're a collection of different parts, each with their own beliefs, needs, fears and ways of protecting us.

If you've ever watched the movie Inside Out, you've already seen this concept brought to life.

Joy.

Sadness.

Fear.

Anger.

Anxiety.

Different emotions step forward depending on what's happening.

Our internal world often works in a very similar way.

Why this matters for weight loss

One of the biggest misconceptions about weight loss is that success simply comes down to discipline.

If that were true, every person who knew what healthy eating looked like would already be at their goal weight.

But that's not what happens.

Most women I work with already know what they "should" be eating.

They know vegetables are healthy.

They know protein is important.

They know moving their body is good for them.

Knowledge isn't usually the missing piece.

The real question becomes:

Why do we keep doing the opposite of what we know we want?

From a Parts Therapy perspective, the answer is often surprisingly simple.

Not every part of you wants the same thing.

One part wants to lose weight.

Another wants comfort.

Another wants freedom.

Another wants to feel safe.

Another simply wants to rest.

None of them are wrong.

They're just trying to meet different needs.

Where do these parts come from?

Our parts don't appear randomly.

They often develop throughout childhood and adulthood as clever ways of helping us cope with life.

Perhaps your Perfectionist developed because achievement was praised.

Perhaps your Nurturer learnt that looking after everyone else made you feel needed or loved.

Perhaps your Teenager developed because there wasn't much room for freedom or fun growing up.

Perhaps your Resting One learnt that shutting down was the only way to recover from chronic stress or burnout.

These parts aren't trying to make life difficult.

Most of them developed with incredibly positive intentions.

The challenge is that what once protected us doesn't always serve us in adulthood.

Four common parts I see in women trying to lose weight

There are hundreds of different parts, and every person is unique.

These are simply four that I meet regularly in clinic.

The Perfectionist

She wants the perfect body.

The perfect meal plan.

The perfect week.

She believes if something is worth doing, it should be done properly.

She's organised.

Driven.

Highly motivated.

She genuinely wants the best for you.

But she's also relentless.

She pushes and pushes until everyone inside is exhausted.

Then the moment life gets messy…

One missed workout.

One takeaway meal.

One birthday dinner.

She throws her hands in the air and says,

"Well…I've ruined it now. I may as well start again Monday."

Ironically, the very part trying to help you become healthier often creates the all-or-nothing thinking that keeps you stuck.

The Protector (she needs Rest)

I jokingly call her "Lazy Daisy" with some clients, but in reality she's rarely lazy at all.

She's usually exhausted.

She's the part asking for comfort.

Recovery.

Slower mornings.

The couch.

A quiet night in.

She's often criticised by the Perfectionist.

But without her we'd probably never stop.

She serves a vital purpose.

The challenge comes when she's only allowed to appear after complete burnout.

The Nurturer

She's beautiful.

Compassionate.

Giving.

She remembers everyone's birthdays.

Makes sure everyone is fed.

Checks in on family and friends.

She genuinely loves caring for others.

The problem comes when she forgets herself.

She slowly transforms into the Martyr.

She gives until she has nothing left.

By the end of the day, she's emotionally empty—and food often becomes one of the few things that feels nurturing.

The Teenager

She's one of my favourites.

She's the rebel.

She doesn't like being told what to do.

When life becomes too restrictive…

Too controlled…

Too responsible…

She pushes back.

She's often blamed for emotional eating.

Wine on a Friday night.

Impulse shopping.

Breaking the rules.

But underneath, she's usually asking for something incredibly healthy.

Freedom.

Play.

Adventure.

Joy.

Connection with yourself.

Without her, life becomes all responsibility and no fun.

Monday You vs Friday You

Let's see how these parts might show up across an ordinary week.

Monday morning.

The Perfectionist has the driver's seat.

You've meal prepped.

You've exercised.

You've hit your protein target.

You've filled your water bottle three times.

Everything feels under control.

Then Tuesday arrives.

Work becomes hectic.

The kids need something.

Lunch becomes whatever you can find between meetings.

The gym doesn't happen.

The Perfectionist quietly whispers,

"Well...that's ruined the week."

The Nurturer steps in.

She gets everyone organised.

Dinner gets cooked.

Homework gets done.

Everyone else's needs are met.

By Tuesday evening you're completely exhausted.

The Protector arrives.

The couch feels irresistible.

Netflix sounds perfect.

The Tim Tams suddenly make complete sense.

Wednesday and Thursday become a dance between caring for everyone else and trying to recover from the exhaustion.

Then Friday rolls around.

The Teenager has had enough.

"Stuff this."

She wants takeaway.

Dinner out.

Wine with friends.

A break from responsibility.

Sunday afternoon arrives.

The Perfectionist quietly returns.

A new meal plan.

A fresh shopping list.

Another promise that next week will be different.

It's a cycle I see over and over again.

Not because women lack motivation.

But because different parts have been taking turns driving the bus without ever talking to each other.

The goal isn't to get rid of your parts

This is one of the biggest misunderstandings about Parts Therapy.

The goal isn't to eliminate your Perfectionist.

Or silence your Teenager.

Or stop your Resting One from appearing.

Every single part has a positive intention.

Every single part deserves to be heard.

The real goal is helping them work together.

Imagine if your Perfectionist could aim for progress instead of perfection.

Imagine if your Resting One was given permission to recover before burnout happened.

Imagine if your Teenager was regularly given freedom, adventure and fun instead of having to create chaos just to be noticed.

Imagine if your Nurturer learnt that caring for herself wasn't selfish.

That's alignment.

And when your parts begin working together instead of fighting each other, healthy habits become much easier to maintain.

What does this look like in a One of my sessions?

People often imagine this work is about analysing every childhood memory or trying to "fix" parts of themselves.

That isn't my approach.

Instead, we become curious.

We notice which part is showing up.

We explore what she's trying to protect.

We understand what she needs.

Then we help the different parts communicate so they begin working together instead of pulling in opposite directions.

These conversations are often incredibly insightful.

Clients regularly tell me,

"That makes so much sense now."

And from that understanding comes something powerful.

Choice.

Self-awareness changes everything

One of my favourite quotes is:

Knowledge creates understanding. Awareness creates transformation.

You can know everything about nutrition.

You can know exactly how many calories are in an avocado.

You can memorise every healthy recipe on Instagram.

But lasting change comes from understanding yourself.

Because when you understand why you're reaching for food, why you keep starting over, and why different versions of you seem to appear throughout the week…

You stop fighting yourself.

You start working with yourself.

And that's where real transformation begins.

A few questions to reflect on

As you've been reading this article, which part stood out to you the most?

Which one has been driving your life recently?

Which part rarely gets a chance to speak?

What do you think she's trying to protect?

You don't need to judge her.

Simply become curious.

Sometimes curiosity is the first step towards lasting change.

Ready to understand yourself on a deeper level?

Parts Therapy is just one of the therapeutic approaches I use inside Weight Loss Mindset Therapy.

Because lasting weight loss isn't simply about changing what you eat.

It's about understanding the different parts of you that influence why you eat, how you respond to stress, and what keeps pulling you back into old patterns.

When we bring those parts into alignment, healthy choices begin to feel less like a battle and more like a natural expression of who you are becoming.

If this article resonated with you, I'd love to hear from you.

Which part did you recognise first?
