If you’ve ever started a new diet or exercise plan, felt motivated for a couple of weeks, and then quietly stopped… you’re absolutely not alone. Most people think this is a “willpower problem”. In reality, it’s usually a strategy problem.
Sticking with a health plan over the long term isn’t about being a superhero. It’s about understanding the forces that get you started, and the ones that keep you going when things get tough.
In this article, I will walk you through a simple framework I use with my clients over 50 to help them stay consistent with diet and exercise for long enough to see real results.
There are five key elements:
- Inspiration
- Motivation
- Discipline (willpower)
- Habit
- Passion
You don’t need all five on day one, but knowing how they work together can completely change how you approach your health.

1. Inspiration: The Spark That Gets You Started
Inspiration is that initial “lightbulb moment”:
- You see a friend who has lost weight and looks healthier
- You watch someone your age do something active you’d love to be able to do
- You get a wake-up call from your doctor
You feel a strong pull to change – today. That’s inspiration. It’s powerful, but it’s also short-lived. You might feel on fire for a few days… and then normal life creeps back in. The feeling fades, and so does the behaviour.
Inspiration is useful because it gets you moving. But it’s never enough on its own to carry you through months or years of change.
That’s where the next piece comes in.
2. Motivation: Your “Why”
Motivation is what keeps you going once the initial excitement has worn off.
It answers the question:
“Why am I actually doing this?”
Your motivation can be:
- Internal – “I want to feel stronger, more confident, and more in control of my health.”
- External – “I want to walk my daughter down the aisle,” or “I’ve signed up for a charity walk.”
And it can be:
- Positive – moving towards something you want
- Negative – moving away from something you don’t want (for example, another health scare or losing independence)
Both types can be useful. For example:
- A client once told me his main motivation was to be able to walk his daughter down the aisle in six months. That’s a powerful positive motivator.
- Another person only really decided to change after someone casually remarked in the supermarket that he “didn’t look well” – a painful but effective negative motivator.
Motivation gives you a reason to keep going. But just like inspiration, it isn’t always there when you wake up at 6am on a cold, dark morning.
So what fills the gap on those days?
3. Discipline: What You Do on the Hard Days
Discipline (or willpower) is what gets you moving when you don’t feel like it:
- Choosing the lighter meal when you’d rather have the burger
- Going for your walk when the sofa looks far more appealing
- Doing your exercises even though you’re tired and a bit grumpy
Discipline is essential, but it has a big limitation: it’s finite.
If you have to lean on willpower all day, every day, eventually it wears thin. That’s why relying on “just be stronger” is such a fragile strategy.
You do need discipline, especially at the beginning. But the goal is not to live on willpower forever. The goal is to use it long enough for the next stage to develop.
4. Habit: Where It Starts to Feel Easier
This is where things really start to change.
A habit is a behaviour you do almost automatically, with very little mental effort. For example:
- Putting your walking shoes on after breakfast without really thinking about it
- Going to the gym every Monday, Wednesday, and Friday because “that’s just what you do”
- Reaching for a glass of water instead of a fizzy drink out of sheer familiarity
At first, these behaviours require effort and discipline. But after a few weeks or months, they begin to feel normal – even easier than not doing them.
I see this a lot with my clients. Someone who once hated the idea of walking becomes the type of person who says:
“I feel strange if I haven’t been out for my walk today.”
That’s a habit. The key things to know about habits:
- They take time to build (those first 6–12 weeks are often the toughest)
- Once they’re established, they save you an enormous amount of willpower
- They make long-term success possible
This is one reason why, counterintuitively, it can sometimes be easier to do something every day (even a small version of it) than to do it “a couple of times a week”. Daily repetition cements the habit faster.
5. Passion: When You Actually Enjoy It
Not everyone will get to this stage with every behaviour – and that’s okay. But when it happens, it’s incredibly powerful.
Passion is when you genuinely like the activity that supports your health:
- You look forward to your walks or gym sessions
- You read about your chosen activity in your spare time
- You talk about it with friends and family because you enjoy it
For some people, that might be hiking. For others, it’s strength training, swimming, cycling, yoga, or a particular sport.
Passion usually develops after you’ve:
- Spent time building the habit
- Felt some of the benefits
- Gained a bit of competence and confidence
You can’t force passion. You can only create the conditions for it to grow by sticking with something long enough.
The Takeaway
Long-term success with diet or exercise isn’t about being “stronger” than other people. It’s about understanding how these five pieces fit together:
- Inspiration – gets you started
- Motivation – gives you a reason to continue
- Discipline – carries you through the tough days
- Habit – makes good choices automatic
- Passion – makes the whole process far more enjoyable
You don’t need to get this perfect. If you’re working on a change right now, try this:
- Clarify your why (write it down somewhere you’ll see it)
- Use discipline to show up for a small, realistic action most days (even 5–10 minutes counts)
- Give it long enough for the habit to take root before you judge whether it’s “working”
Over time, things that once felt impossible can become part of who you are.
