Chapter Eight of Journey Back to Health addresses a frustrating truth: knowing what to do is not enough.

During my graduate studies in psychology, I conducted research with both children and adults. I asked children as young as three to sort pictures into piles labeled “good for me,” “not good for me,” and “okay.” I tested adults between the ages of 18 and 25 on their knowledge about food and health.

Across ages, the pattern was consistent. People know.

They know what’s better for them. They know what isn’t. They understand the basics of sleep, nutrition, and exercise. And yet, chronic illness rates continue to rise. Diabetes, obesity, and heart disease are increasing, even though access to information has never been easier.

We can Google anything. We can ask questions instantly. There’s no gatekeeping of knowledge anymore.

So why don’t we act?

The answer connects back to earlier chapters — the brain resists change. The brain is designed to conserve energy. It needs fuel just to get through a 24-hour day, remember responsibilities, and manage daily life. When we set massive goals, we’re asking our brains to burn enormous amounts of energy.

Consider the typical Monday reset: I’m going to start Whole30. I’m going to work out daily. I’m going to quit coffee. I’m going to fix my sleep.

That isn’t one habit. That’s dozens.

A new diet includes grocery shopping, meal planning, food prep, decision-making, and emotional regulation. Exercise includes scheduling, clothing, transportation, and physical effort. Sleep changes require routine adjustments. Each of these is a cluster of habits layered together.

The brain sees that mountain and immediately resists.

What actually works is breaking change down into the smallest possible step.

For example, if I want to incorporate exercise, I’ve learned that driving to the gym doesn’t fit my lifestyle. It takes hours. So instead, I follow short YouTube workouts that fit between clients. I wear clothes I can move in. I keep a post-it note visible as a reminder.

The goal isn’t perfection. It’s reducing friction so action becomes easier than avoidance.

Ask yourself: What is one tiny step I can take this week?

Not five steps. Not a life overhaul. One.

Maybe it’s consistently eating one meal. Maybe it’s a 10-minute walk. Maybe it’s journaling once.

Chapter Eight’s action step is beautifully simple: share what you’re learning with someone. Accountability changes things. When we tell someone about our goals, we create gentle pressure and community support.
