Over ten years ago, I sounded the alarm on sugar and cognitive decline in Grain Brain. At the time, many considered it radical or fringe thinking.

What surprises me now is how clearly the latest research shows that even natural sugars, like those in fruit and milk, can influence brain health when over-consumed. This is a wake-up call that sugar isn’t just a metabolic concern, it’s a cognitive one.

Your meals are more than just fuel. They shape how your brain and body perform.

Choosing nutrient-rich, anti-inflammatory foods can boost focus, energy, and long-term health.

Here’s a recipe Leize and I have been enjoying frequently as of late:

93% of health issues are not genetic. They’re not your “fate” or “bad luck.”

They’re the result of what you’re exposed to every single day. That means most chronic illness isn’t inevitable, it’s a reflection of your environment, your habits, and your daily choices.

I tell my patients: your genes may load the gun, but the environment pulls the trigger. The Pima Indians prove this perfectly. A century ago, they had zero diabetes, obesity, or heart disease. Today 80% develop diabetes by age 30. Same DNA, completely different outcomes.

What you control every day: the food you eat (it’s literally genetic code that reprograms your cells), how you move, your sleep quality, stress management, environmental toxin exposure, and even your thoughts. Yes, your thoughts actually transform your biology at the cellular level.

When I nearly died from a spinal infection this past December, I couldn’t walk or care for myself. But I understood that the body is designed to heal. I applied every principle I teach my patients, gave my body the right inputs, and came back stronger than I was before the illness.

Here’s the reality: 93% of Americans are metabolically unhealthy because we consume a pound of sugar and flour daily while 73% of grocery store shelves contain ultra-processed fake food. It’s not genetics causing this epidemic.

You’re not a victim of your DNA. You’re the architect of your own health, and your body responds to every choice you make.

Inflammation plays a central role in many chronic conditions, including those that affect the brain. While we can’t control everything, we do have influence over many of the factors that drive inflammation.

Daily choices—what you eat, how you move, how you rest—can help create an internal environment that supports healing and long-term health.

I often recommend starting with simple, sustainable habits: eat more omega-3 rich foods, avoid processed sugar, move your body regularly, prioritize sleep, and make space for mindfulness or meditation.

These actions may seem small, but over time, they help build a strong foundation for brain and body health.

Sleep isn’t just about feeling rested. It plays a powerful role in how your body manages blood sugar.

Research shows that even one night of poor sleep can drive insulin resistance up by 25 percent—similar to what’s seen in early-stage type 2 diabetes. In one study, healthy young adults who slept only four hours per night for six nights experienced this shift.

This is a reminder that rest is not optional. It is an essential part of caring for your brain, your metabolism, and your long-term health.
