We’ve all been there. Fired up with a shiny new goal—whether it’s cutting sugar, hitting the yoga mat more often, or finally getting serious about sleep—only to find ourselves slipping back into old habits a few weeks later.
Why is it that some people can stick with new habits, while others feel stuck in a revolving door of “start strong, fizzle fast”?
Here’s the truth: it’s rarely about willpower. It’s about your “Why.”

Why “Why” Matters
Friedrich Nietzsche said it best: “He who has a Why can endure any how.”
Translation? If you know exactly Why you want something—and that reason is deeply personal—you’ll have the staying power to push through setbacks, cravings, or Netflix binges calling your name.
In functional medicine, we talk a lot about root causes: what’s really driving symptoms, inflammation, or accelerated aging. The same principle applies here. If you want lasting lifestyle change, you need to identify the root cause of your motivation.
The Difference Between a Strong Why and a Weak Why
Let’s be honest. If your Why is “I want to fit into my jeans from college by next month,” chances are slim that motivation will keep you steady when the going gets tough. It’s surface-level, short-term, and usually fueled by comparison.
But if your Why is deeper—like, “I want to reverse my prediabetes so I can be here to see my kids graduate,” or, “I want to heal my gut so I can finally feel comfortable in my body again”—that’s the kind of fuel that doesn’t burn out when temptation strikes.
A weak Why whispers. A strong Why roars.
Your Why needs to be bigger than your excuse. Read that again.
How to Discover Your Why
Finding your Why isn’t always obvious. Most of us don’t sit around reflecting on our inner motivations between Zoom calls and soccer practice. But with a little digging, it will come into focus.
Here are a few ways to unearth yours:
1. Look at Past Wins
Think of a change you actually stuck with. Did you quit smoking? Train for a race? Cut out gluten because it wrecked your gut? Ask yourself: What was so important about that goal that I followed through?
Chances are, you’ll notice a theme—health, freedom, family, energy, confidence. These themes point to your core Why.
2. Ask the “5 Whys”
It’s a simple but powerful exercise: take a goal (say, “I want to cut sugar”). Then ask yourself Why five times.
- Why? → Because I want to lose weight.
- Why? → Because I don’t feel comfortable in my clothes.
- Why? → Because I don’t feel confident in my body.
- Why? → Because I want to feel attractive again.
- Why? → Because I miss feeling connected to my partner.
By the fifth Why, you’ll usually hit gold.
3. Borrow Simon Sinek’s Trick
Simon Sinek (the “Start With Why” Guy) suggests asking friends: Why are you my friend? What do you value about me?
It feels awkward at first, but their answers can shine a light on strengths and values you didn’t even realize were core to your identity. Often, your Why is connected to those same values.
Turning Your Why Into a Roadmap
Once you know your Why, everything else falls into place. Suddenly, waking up early to meal prep or skipping dessert isn’t about restriction—it’s about alignment.
A strong Why transforms daily habits from chores into stepping stones. It gives purpose to your “boring” choices: packing a nourishing lunch, prioritizing sleep, or showing up to therapy instead of numbing out with Netflix.
This doesn’t mean you won’t have off days. But when your Why is strong, you’ll see setbacks as detours—not dead ends.
Habits That Stick: The Functional Medicine Way
In functional medicine, we know that small, consistent actions compound into big change. Healing your gut, balancing your hormones, or calming inflammation doesn’t happen in a week—it happens with steady micro-choices over months.
Lifestyle change works the same way. Here’s how to build habits that last:
- Anchor to routines you already have. Brush your teeth? Add five minutes of meditation right after. Pour coffee? Sip water first. Stack new habits onto old ones.
- Make it stupid simple. Don’t vow to run five miles a day if you’re starting from zero. Start with ten minutes of walking. Build from there.
- Celebrate small wins. Your brain loves dopamine. Give yourself credit for the tiny victories, and your motivation will grow.
- Expect resistance. Change is uncomfortable by design. The trick isn’t avoiding discomfort—it’s reframing it as evidence you’re growing.
The Three Pillars of a Powerful Why
When you’re searching for what really motivates you, these three pillars can help:
1. What Makes You Come Alive?
What lights you up? Is it feeling present with your kids, traveling with energy, or leading with confidence at work? Your lifestyle habits should support those sparks.
2. What Are Your Strengths?
Are you a natural encourager? A planner? A creative problem-solver? Leverage your strengths. If you love structure, build a wellness calendar. If you’re social, buddy up for workouts.
3. What Legacy Do You Want to Leave?
How do you want to be remembered? As someone vibrant, resilient, and full of life—or someone burned out, stuck, and always “too tired”? Long-term vision can reframe short-term sacrifices as meaningful investments.

Functional Medicine + The Why Connection
Here’s where functional medicine makes this conversation unique: your Why doesn’t just motivate you—it can literally change your biology.
Think about it: chronic stress and lack of purpose flood your body with cortisol and adrenaline. Over time, that weakens your gut lining, scrambles your hormones, and accelerates aging.
On the flip side, clarity of purpose creates a sense of safety in your nervous system. This reduces inflammation, balances hormones, and even supports mitochondrial function (a.k.a. your energy engines).
So yes—finding your Why isn’t just motivational fluff. It’s biochemistry.
What This Looks Like in Real Life
Let’s say two women decide to stop drinking soda.
- Woman A’s Why: “I want to lose five pounds before my high school reunion.”
- Woman B’s Why: “I want to lower my blood sugar so I don’t repeat my mom’s struggle with diabetes.”
Guess which one is still soda-free six months later?
That’s the power of a deeply rooted Why. It turns short-term behavior into long-term identity.
Putting It All Together
If you’re feeling stuck or frustrated with lifestyle changes, stop white-knuckling it. Pause. Ask yourself:
- Why does this matter to me?
- What am I really working toward?
- How will my life be different when I get there?
Write it down. Put it on your fridge. Remind yourself daily.
And when you stumble (because we all do), revisit your Why. Let it re-center you.
The Sweet Spot: When Your Actions Align With Your Why
Here’s the magic: when your habits line up with your Why, you stop feeling like you’re fighting yourself.
Eating anti-inflammatory foods becomes less about “what I can’t have” and more about “what makes me feel amazing.” Prioritizing sleep becomes less about FOMO and more about waking up energized for the things that matter most.
The journey stops being punishment and becomes empowerment.
Final Thoughts
Lifestyle change is hard. But it doesn’t have to be a tug-of-war if you anchor yourself to a strong, deeply personal Why.
When you do, you don’t just transform your habits—you transform your biology, your beauty, and your future.
So, ask yourself today: What’s my Why?
Find it. Write it. Live it. And watch as the everyday choices that once felt impossible become the most natural thing in the world.
Because the truth is, lasting transformation doesn’t start with discipline. It starts with desire—rooted in a so powerful, it pulls you forward even on your hardest days.
