After 15 years in fitness, Dr. Joey has reversed his stance on three things: that calories alone determine fat loss, that more training volume is always better, and that having kids and a full-time career makes staying fit exponentially harder than it actually turns out to be.
Fifteen years into coaching, a PhD, and building a life that includes two young kids and a company, Dr. Joey's perspective on fitness has shifted in ways his younger self would have argued against. Not because the fundamentals changed, but because real life added nuance that theory alone never could.
Here are the three beliefs he used to hold with total confidence, and what actually changed his mind.
Belief One: Calories Are the Only Thing That Matters
Early in his career, Dr. Joey treated calories as the single lever that mattered for fat loss, full stop. Technically, that's not wrong: a calorie deficit is required to lose fat. But treating it as the only variable worth considering misses everything that determines whether a deficit is actually sustainable.
Food quality, protein intake, and how full a meal actually leaves you feeling all shape whether someone can hold a deficit for weeks or months instead of days. Two diets with identical calories can feel completely different to stick with, and that difference is often what separates progress from another failed attempt.
Belief Two: More Training Volume Is Always Better
For years, the assumption was straightforward: more volume, more intensity, more growth. In college, that meant training five, six, sometimes seven days a week for an hour and a half or more, driven purely by how much he loved being in the gym.
Theoretically, more volume does drive more progress, with one major caveat: you have to actually recover from it. Recovery capacity is shaped by sleep, stress, nutrition, genetics, and simply how much else is going on in your life. Being forced down to three sessions a week for the past several months, due to a fuller schedule, ended up producing results that surprised him.
Six to seven sessions a week, 90+ minutes each, because more volume theoretically means more muscle and strength gained.
Three focused sessions a week, matched to actual recovery capacity, can maintain strength and muscle just as effectively.
Volume that outpaces your recovery doesn't just stop helping, it actively works against progress. The right amount of training is the amount your life can actually recover from, not the maximum theoretically possible.
Belief Three: Kids and a Career Make Fitness Exponentially Harder
It is a little bit more difficult, but it really comes down to prioritization, time management, and making the right choices.
This is the belief Dr. Joey expects to ruffle some feathers. Before having kids, he assumed adding them to an already busy life, doctoral coursework, lab work, teaching, would make health and fitness dramatically harder to maintain. Looking back at how busy he genuinely believed he was during grad school, without kids, now feels almost laughable.
What he's realized is that capacity for work and time management skills both develop over time. Someone in their early twenties without kids often feels maximally busy in the moment, even though, looking back, they had far more slack than they realized. That same pattern repeats at every stage: the current season always feels like the busiest one, until the next season arrives and proves otherwise.
- Calories matter enormously, but food quality and satiety determine whether a deficit is sustainable long enough to work.
- More training volume only helps up to the point your recovery, shaped by sleep, stress, and life circumstances, can match it.
- Three well-structured sessions a week can maintain results that once seemed to require six or seven.
- Kids and a demanding career make fitness somewhat harder, but prioritization and time management matter more than raw free time.
- Your capacity to manage a fuller life tends to grow over time, often further than you'd assume from where you stand today.
None of these shifts came from reading a new study. They came from actually living through the version of life theory alone couldn't predict, and adjusting the beliefs that didn't hold up against it.
Frequently Asked Questions
Are calories really the only thing that matters for fat loss?
Calories matter enormously for fat loss, but treating them as the only variable that matters misses food quality, protein intake, and satiety, all of which determine whether a calorie deficit is sustainable long enough to actually work.
Is more training volume always better for building muscle?
Not necessarily. More volume theoretically drives more growth, but only if your recovery capacity, shaped by sleep, stress, nutrition, and life circumstances, can keep up with it. Beyond your recovery limit, added volume stops helping and starts working against you.
Does having kids or a demanding job make fitness exponentially harder?
It makes it somewhat harder, but not to the degree most people assume before they're in it. Prioritization and time management usually matter more than the raw amount of free time available, and capacity to manage a full schedule tends to grow over time.
Why do busy people underestimate their own capacity for consistency?
People often assume their current, less busy season represents their true capacity, without realizing that time management skills and the ability to handle a full schedule develop with practice. What feels impossible now often becomes manageable once it becomes necessary.
