The Pleasure Prescription: Why Joy Moves the Needle on Your Labs.

Okay, friends. Pull up a chair. I want to tell you about a study that made me grin all the way through my morning coffee.

Stanford researchers (Crum & Langer) gathered 84 hotel housekeepers — women already on their feet all day, scrubbing tubs, hauling linens, climbing stairs. They split them into two groups. One group was told, simply: the work you are already doing counts as exercise. It meets the federal activity guidelines. The other group was told nothing.

Nobody changed their behavior. Nobody added a workout. Nobody changed what they ate.

Four weeks later, the women who knew their movement counted had measurably lower weight, lower blood pressure, lower body fat, lower BMI, and a smaller waist-to-hip ratio than the women who didn't know.

Same bodies. Same buckets. Different story — different physiology.

Let that land for a second. Because this isn't only about exercise. This is about every step you take toward your health, and the story you tell yourself while you're taking it.

The glass of water you actually wanted. The walk you took because the light was beautiful. The dinner you cooked slowly because you wanted to smell the garlic hit the pan. The stretch you did because your shoulders were asking for it. None of those things are small. And the way you feel about doing them is part of the medicine.

This is why joy sits at the center of everything I teach. Not as a garnish. Not as a reward you earn after the "real" work. As the mechanism.

The research keeps confirming it. A one-year follow-up of new exercisers in Frontiers in Psychology found that enjoyment — not motivation, not discipline, not goals — was the single strongest predictor of who was still moving a year later. A 2025 study in Taylor & Francis found that the felt experience of movement (joy, calm, accomplishment) determined whether people came back to it, more than intensity or duration. And a review in PMC concluded that enjoyment is one of the strongest psychological predictors of habit formation, period. We repeat what feels good. What we repeat compounds. What compounds becomes our metabolism.

Here is the part I want you to remember:

You were given five senses for a reason.

You were not built to white-knuckle your way to better labs. You were built to taste, to smell, to see color, to hear your own laugh, to feel the warmth of a hand or a sunbeam or a hot bath. Health that ignores your senses isn't health — it's a sentence. And bodies, it turns out, do not heal under sentencing. They heal under delight.

So this week, a small experiment. Pick one thing you are already doing for your health — the morning walk, the leafy greens, the bedtime wind-down, the glass of water before coffee — and instead of grading it, savor it. Let yourself enjoy it on purpose. Notice the way the air smells on the walk. Notice the crunch of the salad. Notice how your shoulders soften when you finally turn off the screen.

That noticing is not fluff. According to the data, it is one of the most metabolically active things you can do.

Your body is listening to the story you tell about it. Tell it a beautiful one.

(P.S. If this is hitting a nerve and you want to go deeper — I'm hosting a free webinar tonight at 8 PM: Reversing Prediabetes with Joy. We'll talk about exactly how this mindset-and-pleasure piece becomes a clinical tool for moving your A1c. I would love to see you there.)

With joy,
