Why you can't build an empire with sugar brain
How to eat and move like a high performance CEO
If you cannot manage your insulin, you have no business trying to manage a balance sheet. Most high-performers are building empires on a foundation of wet sand. You think you can trade your health for money and just “fix it later,” but your biology doesn’t work that way.
I have seen brilliant operators with $50 million exits who are effectively dead inside because they treated their bodies like a dumpster for two decades. That isn’t success. It is a slow-motion suicide pact with your own ambition.
I remember sitting in a meeting in 2019 with a $3.2 million marketing contract with the biggest personal injury attorney in Colorado on the table... my hands were literally shaking because I had spiked my glucose with a “quick” bagel and then crashed into a hypoglycemic abyss.
I looked like a nervous amateur because I didn’t have the energy to stay stable. I was making world-class decisions with a brain that was starved of fuel. You are currently doing the same thing every time you choose convenience over chemistry. You are burning through your most valuable currency: ABILITY.
The science is cold and unforgiving. According to research from Oxford, insulin resistance is the silent killer of executive function. When your insulin levels are chronically high, your body loses the ability to access its own fat stores for fuel. You become a slave to the next sugar hit just to keep your brain from fogging over.
High-quality protein and healthy fats are not optional “diet” choices. They are the structural requirements for a brain that can handle high-stakes pressure without folding.
You need to pivot to a high-protein, high-fat protocol if you want to protect your nervous system. Fat is a slow-burning, high-octane fuel that doesn’t cause the massive insulin spikes that rot your focus. Protein provides the amino acids that build the neurotransmitters you need to lead.
Harvard research has shown that high-sugar diets actually shrink the hippocampus... the part of your brain responsible for memory and learning. You are literally making your brain smaller to satisfy a craving for refined carbs.
Muscle is your metabolic insurance policy. It is not about looking good in a tailored suit. It is about building a “glucose sink” that protects your brain. Every pound of lean muscle mass you carry is a dedicated storage unit for excess blood sugar.
Research from the Mayo Clinic proves that resistance training is one of the most effective ways to improve insulin sensitivity. If you don’t have muscle, every gram of sugar you eat stays in your bloodstream longer... causing inflammation and destroying your blood-brain barrier.
You need to stop treating exercise like a “nice-to-have” hobby you do when the work is done. It is a non-negotiable part of your scale strategy. If you don’t have the muscle to absorb the glucose, your body will pump out more insulin to compensate. This leads to systemic inflammation that makes you tired, reactive, and irritable. You can’t lead a team if you can’t even lead your own hormones.
The price of leadership is VIGILANCE. You need to audit your fuel with the same intensity you audit your P&L. If you aren’t hitting at least one gram of protein per pound of ideal body weight and lifting heavy weights twice a week, you are leaving your best years on the table. You are trading your long-term autonomy for a short-term dopamine hit.
The grind won’t kill you, but the inflammation will. Stop being a highly-paid operator with a failing engine. Build a body that can actually sustain the life you are trying to design. There is no freedom in being a prisoner to a sugar crash. You protect your equity with lawyers... now protect your biology with discipline.
3 Actionable Steps to Reclaim Your Health and Your Brain
1. Start a 30-Day Sugar Reset
No sodas, no sweets, no refined carbs. Add protein and vegetables at every meal to stabilize blood sugar. Track your focus, energy, and sleep.
2. Commit to Movement
3 strength sessions per week + three 20-30 minute walks outside. Treat them as non-negotiable meetings, they’re that important. You can even turn your meetings into “walking meetings.” I have those every week.
3. Audit Your Fuel
If the ingredient list looks like a chemistry experiment, it’s not food. Stick to whole, single-ingredient foods. Avoid ultra-processed items cooked in cheap oils. Watch how your brain clarity, mood, and productivity respond.
We chase success because we want freedom.
But there’s no freedom in feeling exhausted, foggy, or dependent on sugar and caffeine just to function.
Protect your body the way you protect your business.
Because at the end of the day, your health is your most valuable equity.




Thanks Dennis, such great advice. I am definitely on-track for the movement and exercise you recommend, and I don't have too much sugar, but I really would struggle without caffeine, I think. I have kind of okayed it though, as it is pretty much my only vice (teetotal and non-smoker).
Great advice Dennis. I love my desserts THE most, but try to simultaneously be aware and move around, eat less sugar!
