Coaching, Cake, and the Real Purpose of Exercise

If you've ever felt like exercise only "counts" if it changes your body size, you're not alone. That belief is everywhere—and it's one of the fastest ways to turn movement into pressure, shame, and burnout.

What Actually Happened (and Why It Matters)

Last week, I shared a lighthearted moment on Facebook about a client who trained four times a week for three weeks before Christmas. In the post, I jokingly warned them not to eat "all the yams and cakes" over the holidays.

They looked me dead in the eyes and said they were doing the extra work precisely because there was a whole black forest cake with their name on it—and Haitian yams to show out for.

I couldn't even be mad. It was funny. It was human. It was a moment of genuine connection between coach and client.

One commenter, however, saw something else entirely:

"You a horrible coach," they wrote. "You need to let the clients know the honest truth. You can not out exercise a bad diet so she basically set herself back and those workouts was for nothing."

In that moment, a silly, celebratory exchange became a straw man for everything that can go sideways in fitness culture: the idea that exercise only "counts" if it changes body size, that coaches should police food, and that a single social media snapshot can accurately represent an entire coaching relationship.

The commenter saw a coach "allowing" a client to fail. I saw a coach recognizing a client's autonomy, cultural joy, and the reality that health isn't built—or destroyed—by a single holiday meal.

"You can't out-exercise a bad diet": the truth inside the cliché

"You can't out-exercise a bad diet" is one of those sayings that contains a grain of truth wrapped in a lot of oversimplification.

If someone's only goal is weight loss, exercise by itself often produces smaller changes on the scale than people expect. That's partly because bodies adapt: when activity increases, total daily energy expenditure doesn't always rise in a perfectly linear way.

But here's the part that gets lost: exercise is still profoundly protective for health, even when weight doesn't change much.

If weight loss isn't your goal, what can movement be for?

Movement can support:

• Steadier mood and stress tolerance
• Better sleep quality
• Strength for daily life (stairs, carrying groceries, getting up off the floor)
• Blood sugar regulation
• Joint support and pain management
• Confidence and trust in your body
• A sense of agency—doing something because it serves you, not because you're being punished

Those are real outcomes. They matter. And they're not "for nothing" just because someone ate cake.

Exercise works in ways the scale can't measure

Higher cardiorespiratory fitness (CRF) is consistently associated with lower risk of all-cause and cardiovascular mortality across body sizes. Fitness matters, and it matters a lot.

So when my client trained four times a week before Christmas, they weren't "setting themselves back." They were building fitness, strength, and consistency—benefits that aren't erased by enjoying cultural foods during a holiday.

The problem with weaponizing "calories in, calories out"

As Dr. Fatima Cody Stanford (Harvard Medical School) has put it, the simplistic framing of "a calorie in and a calorie out" for weight loss is "not only antiquated, it's just wrong."

Bodies aren't calculators. Appetite, stress, sleep, hormones, medications, chronic illness, and metabolic adaptation all influence how intake and expenditure play out in real life.

Holidays don't derail people—shame spirals do

A day or two of "fun foods" doesn't erase weeks of training. What does derail people is the shame spiral: "I messed up, so I might as well quit."

My client's confidence in their choice—and our shared laughter about it—protected against that spiral. That matters.

The scope of a coach: guide, not gatekeeper

My job isn't to police what my clients eat. My job is to provide evidence-informed guidance, education, and support while respecting autonomy.

Approaches grounded in autonomy support emphasize curiosity, collaboration, and helping clients make choices they can sustain. Rigid rules and shame can create short-term compliance. They rarely create long-term change.

A better framework for thinking about exercise and food

• Exercise for health, not punishment. Movement is not penance for eating.
• Focus on consistency, not perfection. One meal doesn't define health.
• Respect autonomy. Adults deserve to make informed choices without shame.
• Measure what matters. Strength, stamina, sleep, mood, function, confidence—these are real outcomes.

Conclusion

My client who trained for cake wasn't being failed by their coach. They were being treated like a whole person—someone with cultural traditions, celebratory moments, and the capacity to make their own choices.

The cake was eaten. The yams were enjoyed. The client was happy. And the coaching? It worked exactly as it should.
