People come to The Loft looking for answers. And Joe gives them many things ... a safe space, hard conversations, tools for navigating the hardest seasons of life. But there's one framework he comes back to again and again, in session after session, with client after client.
Five things. Five things you can actually control when it comes to mental health. Not just mood or behavior, but the actual health of your brain.
He calls them the controllables.
Why the brain first?
Most of us were taught to think about mental health as something that happens in the mind. Thoughts, feelings, behaviors. And that's true but it's only part of the picture.
The brain is a physical organ. And like every other organ in the body, what you do to it (and for it) every single day matters. The food you eat, the sleep you get, how much you move, how connected you feel, and how much time you spend in the natural world all have a direct and measurable impact on how the brain functions.
This isn't theory. It's biology. And it means that some of the most powerful things you can do for your mental health happen outside of a therapist's office.
The five controllables
Sleep
The brain does its most important work during sleep; consolidating memories, regulating emotions, clearing waste products that build up during the day. When sleep is disrupted or cut short, everything else suffers. Focus, mood, impulse control, anxiety, all of it gets harder. Sleep isn't a luxury. It's the foundation everything else is built on.
Nutrition
The brain runs on what you feed it. Protein, healthy fats, complex carbohydrates, these are the building blocks of neurotransmitters, the chemicals that regulate mood, attention, and stress response. Skipping breakfast or running on processed food means running the brain on empty. A protein-rich meal within 90 minutes of waking is one of the simplest and most impactful changes anyone can make.
Movement
Moving your body is fertilizer for the brain. It increases blood flow, stimulates the growth of new neural connections, and releases the chemicals that make focus and emotional regulation possible. For anyone dealing with anxiety or dysregulation, moving your body before a mentally demanding task isn't just helpful, it's often essential. Even 20 minutes changes the brain's chemistry.
Community
Human beings are wired for connection. The brain literally functions differently in the presence of safe, trusted relationships — stress hormones decrease, oxytocin rises, and the nervous system settles. People who feel genuinely connected are more resilient, more regulated, and more able to do the hard work of growth. Isolation, even quiet isolation behind a screen, has the opposite effect.
Nature
This one surprises people. But the research is clear! Time in natural environments reduces cortisol, lowers heart rate, and improves attention and mood. The brain didn't evolve in fluorescent-lit offices and overscheduled days. Unstructured time outside, even 15 minutes, is one of the most underused tools available to anyone.
What this means for you
Joe isn't sharing this framework to add more to your plate. He's sharing it because most people are already doing some of this — and don't realize how much it matters. And most people have one or two controllables that are quietly dragging everything else down.
The Family Brain Audit was built around exactly this framework. It's a free one-page check-in that helps you see where you're strong and where one small change could make a real difference.
There's a sixth controllable Joe has been thinking about for a while. Can you guess what it is? We'll be sharing it soon.
