Why You Don’t Actually Need a “Faster” Metabolism — And What Matters More

If you’ve ever found yourself thinking, “My metabolism must just be slow,” you’re not alone.

It’s something I hear all the time, from clients, friends, even family members who are trying to do all the right things but still feel stuck. Maybe the weight won’t shift, the energy never quite returns, or it feels like you’re constantly working harder than others for fewer results.

And I get it. Because at some point, most of us wonder the same thing: Is my body just not built for this?

Here’s the truth, not the pop culture version, not the supplement marketing version, but what the science actually says.

What “Metabolism” Really Means

We’ve been sold this idea that metabolism is like a speed dial, something you can crank up with the right foods, workouts, or miracle products. But your metabolism isn’t a switch you flick, it's the sum of everything your body is doing to stay alive and functional, from hormone production and digestion to tissue repair and movement. It’s not a speed; it’s a system.

So when someone says they want to “boost their metabolism,” what they usually mean is: “I want to burn more energy without feeling like I have to do more.” That feeling, of wishing your body could do more with less effort, is completely valid. But to shift that reality, we need to understand what actually drives the system.

Your Total Daily Energy Expenditure (TDEE)

The lens I use with every client, whether their goal is fat loss, better energy, or simply clarity, is TDEE, or Total Daily Energy Expenditure. This refers to the total amount of energy your body burns over a 24-hour period. TDEE has four key components:

1. Resting Metabolic Rate (RMR) – 🧠🫀🫁~60–70% of your daily energy expenditure. This is the baseline cost of being alive, the energy needed to power your brain, organs, and basic cellular functions at rest.

2. Non-Exercise Activity Thermogenesis (NEAT) – 🚶‍♀️💼🧍~15–30%, depending on lifestyle. These are the calories you burn through unstructured movement: standing, walking, fidgeting, doing household tasks, or even pacing while thinking. NEAT is highly variable, and highly trainable.

3. Thermic Effect of Food (TEF) – 🍽️🔥~8–15%, depending on food quality and macronutrient composition. This is the energy your body uses to digest, absorb, and metabolise your meals. Protein has the highest thermic effect, followed by carbohydrates, and then fat.

4. Exercise Activity Thermogenesis (EAT) – 🏋️‍♂️🏃‍♀️🚴~5–10% for most people. This includes intentional exercise, structured workouts like strength training or cardio sessions. While important, it’s often overestimated in its contribution to daily energy burn.

Why This Actually Matters More Than You Think

Here’s where it gets interesting. The two most powerful, and controllable, levers you can pull to influence your TDEE are:

• Building or maintaining muscle, which elevates RMR

• Increasing your daily movement, which improves NEAT

Most people focus solely on workouts, thinking that the key to “burning more” is training harder or longer. But exercise (EAT) often accounts for less than 10% of your daily burn, unless you’re an elite athlete.

NEAT, on the other hand, can quietly account for up to 30% of your energy use, and it’s happening all day long. Choosing to stand instead of sit, walk the dog, or take a call while pacing, those choices add up far more than you think.

And your Resting Metabolic Rate, driven heavily by muscle mass, is by far the largest slice of the pie. This is why preserving muscle as you age is arguably one of the most critical things you can do for long-term metabolic health.

The “Higher Delta” Advantage

Let’s imagine two people who maintain their weight and performance equally well. One consumes 2,000 calories per day. The other can do it on 3,000.

The second person has a higher metabolic capacity, more flexibility, more nutrient throughput, more resilience. They can eat more, recover better, and adapt faster to change.

That doesn’t come from luck. It comes from having more lean mass, better daily movement habits, and a system that’s trained to burn and rebuild efficiently. This concept, sometimes called the “higher delta” is one of the most powerful advantages you can build into your body. Not just for fat loss, but for how you feel, function, and age.

So, Can You Actually Boost Your Metabolism?

Not in the way the ads promise. You can’t “speed it up” like revving a car engine.

But you can absolutely:

✅ Burn more energy by building muscle ✅ Support your body’s natural adaptation with more movement ✅ Choose foods (like protein) that cost more to digest ✅ Build a system that feels faster because it's more efficient and responsive

You don’t need to outsmart your metabolism. You need to align with how it works, and support it to do what it already wants to do.

If You’ve Made It This Far

You’re likely someone who values logic, evidence, and practical strategies over hype.

Maybe you’ve tried things that didn’t work. Maybe you’re tired of the noise, the conflicting advice, and the short-term thinking. Or maybe you’re just curious about how to build a body that works with you, not against you.

If that’s you, I’d love to help.

No sales pitch. No magic fix. Just a thoughtful conversation about how your metabolism works, and how to create a strategy that supports the version of health you actually want to live with.

Because the goal was never a “faster” metabolism. The goal is a smarter one.
