The most impactful thing you can do for your health and overall quality of life is to be less fat.

That’s it.

Just be less fat.

Not ripped like an athlete or skinny like a runway model. Just less fat. Unfat. And most importantly, not obese.

Obesity is the elephant in the room, the monster hiding in plain sight. For many otherwise preventable health issues, like heart disease and diabetes, obesity is a major cause. It also contributes to more complex concerns like cancer and mental health.

It would be overstating it to say all disease is preventable by avoiding obesity. That would be stupid. Life is more complicated than that. But it is true that obese people are at higher risk of suffering from nearly every disease. So, if you want to prevent heart disease, live longer, and be healthier overall, just don’t be obese, right?

Simple.

Except, looking around, it clearly isn’t.

Obesity has been headline news for decades. In that time, we’ve had every possible solution thrown at us. Diet books. Meal plans. Fitness challenges. Follow-along workouts. Gym memberships. Apps. Courses. Wearables. Influencers in very small shorts explaining why everyone else is wrong.

And yet the problem keeps getting worse.

That should tell us something.

Maybe information isn’t the answer.

Eat Less, Move More? Good Luck.

Compared to 1975, the average person today knows far more about exercise and nutrition.

Back then, most people probably didn’t have a gym membership unless they trained for sport. They certainly couldn’t tell you the difference between protein and carbohydrates. They weren’t arguing about keto, low carb, Paleo, intermittent fasting, seed oils, or whether fruit is secretly making everyone fat.

Today, even people who don’t consider themselves “gym people” know the basics.

They know they should move more.

They know they should eat more protein and vegetables.

They know they should drink more water.

They know they should minimise processed food.

They know they should get more sleep.

They know.

And still, knowing hasn’t fixed it.

We’re more educated and aware of the dangers of obesity than ever before, but we’re also more obese than ever. Perhaps, then, knowing more isn’t the solution.

When we look at obesity, food is the obvious place to start. We eat more than we used to. We eat more calorically rich, highly processed, highly palatable foods. The availability of these foods and the ease with which we can access them is probably ten times what it was in the 70s.

But it’s not just food.

Zooming out, it becomes clear that our lifestyles are equally responsible. We eat more, yes. But we also move less.

Given the rise of gym culture, that seems hard to believe. More people train now than they did forty years ago. More people lift weights. More people wear activewear. More people know what creatine is. But structured exercise is not the same thing as movement.

You can train three times per week and still spend most of your life sitting on your arse.

That’s what modern life has done.

We sit at work. We sit in cars. We sit on trains. We sit on the couch. We sit while scrolling. We sit while ordering food to be delivered by someone else, who is at least moving more than we are.

Technology has removed thousands of tiny physical efforts from our lives.

Washing machines removed work.

Dishwashers removed work.

Uber removed walking.

Food delivery removed cooking.

Online shopping removed carrying things.

Smartphones removed boredom, which used to force people to actually do something.

None of those things are bad on their own. I’m not suggesting you smash your dishwasher and start hand-washing plates in a river like some sort of wellness caveman. But all of these conveniences add up.

We do fewer chores. We spend more time sitting at work. We cook less. We walk less. We carry less. We leave the house less.

Modern life allows the body to opt out.

And most of us have accepted the invitation.

All Sloth, No Sleep

After eight hours sitting at a desk, we get home and, instead of doing something active, flop down in front of the TV to unwind.

Then we get hungry.

So we pull out the smartphone and order food to our door. This usually means more calories than if we had cooked at home. It also means we’re more likely to make poor choices because we’re tired and hungry. Nobody opens a food delivery app at 8:30pm after a long day and thinks, “You know what I’d love? White fish and steamed broccoli.”

On top of that, ordering food removes the movement involved in preparing food. No walking around the grocery store. No carrying bags. No chopping. No cleaning. No bustling around the kitchen.

All because we want to “optimise our time.”

But why?

So we can spend more time doing nothing?

Then we stay up late doing nothing, lying in bed, scrolling on our phones, sacrificing hours of valuable sleep.

Poor sleep is not just about feeling tired. It affects memory, focus, mood, decision-making, hunger, hormones, training performance, and your ability to not be a prick to people you love. It makes everything harder. It creates the perfect environment for poor choices to take hold.

Bad sleep makes you crave more food.

More food makes you fatter.

Being fatter makes sleep worse.

Worse sleep makes training harder.

Harder training makes you less likely to train.

And around we go.

The crazy part is not just that we’re guilty of this. It’s that we know we’re guilty of it.

We know we’re doing it.

We know it’s a problem.

And we keep doing it anyway.

Knowing Isn’t Doing

This is the Health Paradox.

We know what helps us, and we avoid it.

We know what hurts us, and we keep doing it.

Most people don’t need another lecture about vegetables. They don’t need another podcast telling them sleep matters. They don’t need another list of the benefits of walking. They don’t need some shirtless bloke on Instagram explaining that lifting weights is good for you as if he cracked the human code.

Most people already know enough to get into much better shape.

They know they should move more.

They know they should make better food choices.

They know they should sleep more.

They know they should drink less.

They know they should probably stop eating like a raccoon with a credit card.

We all know this.

And don’t fix it.

Why?

If we know what to do, and even how to do it, why do we keep fucking up?

That’s the question underneath everything.

The problem is not really choice. Not in the simple way people talk about it. The problem is habit. Conditioned actions repeated so often they become automatic.

To solve the Health Paradox, we need to interrupt the interruptions. It’s not just about starting to do the things we know we should. We need to learn how to stop not doing them.

That starts with understanding why we’re not doing them.

Because your life is set up to make unhealthy choices easy.

Because your environment rewards convenience.

Because your habits are stronger than your intentions.

Because the immediate reward usually beats the future benefit.

Because your current identity is built around the behaviours you keep repeating.

That’s the bit people miss.

You don’t become healthy because you know more. You become healthy because you start acting like a healthy person often enough that, eventually, you believe it.

Why Terrible Is Better Than “Not Bad”

The Health Paradox dovetails with another phenomenon, called the Region-Beta Paradox.

The basic idea is that we often wait for a problem to become bad enough before we take effective action. If something is terrible, we act. If it’s only “not bad,” we tolerate it.

This happens with health all the time.

If you’re fifty pounds overweight and your doctor gives you a serious warning, you might finally take action. But if you’re only five or ten kilos heavier than you’d like, you probably won’t. You’ll tell yourself it’s not that bad. You’ll fix it after the busy period. After Christmas. After the holiday. After work settles down. After life becomes less life-like.

But life doesn’t calm down.

The problem with “not bad” is that it lets you lie to yourself.

You can still function. You can still work. You can still make money. You can still wear the bigger shirt. You can still avoid photos. You can still tell yourself it’s just a phase.

Then one day it’s not a phase.

It’s your body.

It’s your identity.

It’s who you’ve become.

In other words, it can actually be “better” to be in terrible shape than slightly out of shape, because terrible gets your attention. “Not bad” lets you keep drifting.

It’s Not Your Fault, But It Is Your Problem

This is where people get defensive, because conversations about obesity and health choices can easily start sounding like blame.

That’s not useful.

The modern world was not designed around your long-term health. It was designed around convenience, profit, speed, entertainment, and removing friction.

None of this was intentional or nefarious. There’s no evil mastermind twisting his moustache and rejoicing in a world full of obese people. We all got here together.

Technology made life easier.

Food became more available.

Work became less physical.

Entertainment became endless.

Comfort became normal.

Over time, we became bad at dealing with challenge itself. We got used to fast rewards, easy food, constant stimulation, and the removal of discomfort.

So no, it’s not entirely your fault.

But it is your problem.

Your body is your responsibility. Your energy is your responsibility. Your health is your responsibility.

That might sound harsh, but it’s actually freeing.

Because if your current body and habits were built by repeated choices, your future body and habits can be built the same way.

Not through one heroic moment.

Not through a twelve-week transformation where you train like a lunatic, eat like a monk, and then rebound because living like that is miserable.

Through small, repeated behaviours.

Walking.

Training.

Sleeping.

Eating proper food.

Drinking water.

Tracking what matters.

Doing the boring shit long enough that it becomes normal.

That is identity change.

You stop being a person trying to get healthy and become a healthy person.

A healthy person doesn’t need to negotiate with themselves every time they go for a walk. They don’t need a motivational speech to eat protein. They don’t need their life to be perfect before they train.

They do the things a healthy person does.

Not perfectly. Not always. But consistently enough.

That’s the way out of the Health Paradox.

Not more information.

Not more motivation.

Not waiting until the problem becomes terrible.

You need to stop stopping. Quit quitting. Build evidence that you are the kind of person who does what they say they’re going to do.

Because the time will pass anyway.

A year from now, 365 tomorrows will have passed. You can spend them reinforcing the habit of not changing, or you can use them to build something better.

You don’t need to fix everything today.

But you do need to stop telling yourself you’ll start later.
