I have been health-conscious for as long as I can remember.

As a teenager, I lifted weights, watched what I ate, and tried to follow what I understood to be “healthy eating.” Later, as a physician, I assumed that my medical education had given me reliable guidance on nutrition. Like most doctors, my formal training in this area was limited and heavily influenced by the old USDA food pyramid.

Grains were supposed to be the base of our diet. Fat was to be minimized. Carbohydrates were presented as the primary fuel.

With years of experience and a much deeper understanding of metabolic health, I can say plainly: the nutritional framework I was taught in medical school did not help prevent disease. In many ways, it drove it.

How the Old Food Pyramid Set Us Up to Fail

The most damaging feature of the food pyramid was its insistence that grain-based foods be the foundation of daily intake. In practice, this meant large servings of bread, cereal, pasta, rice, and other grain products. For many Americans, that turned into a diet dominated by refined carbohydrates.

From a biological and evolutionary perspective, this is a strange choice.

For hundreds of thousands of years, no primate regularly ate cultivated grains. Suddenly, in the last ten thousand years—and especially in the last hundred—we built a food system in which highly processed grains supply a huge percentage of daily calories.

Grains, particularly when refined, are rapidly absorbable carbohydrates. They spike blood sugar quickly. Their seed coats contain proteins and compounds that plants evolved to discourage animals from eating them. Compared with nutrient-dense foods like vegetables, high-quality proteins, and whole fruits, they offer relatively little in the way of vitamins and minerals per calorie.

When you anchor your diet in high-glycemic grain products, you are effectively choosing a pattern of eating that drives repeated sugar spikes, repeated insulin surges, and eventual insulin resistance. That is the metabolic backdrop for obesity, type 2 diabetes, fatty liver, cardiovascular disease, and a long list of downstream problems.

How High-Glycemic Eating Drives Overeating and Disease

One of the simplest ways to understand the problem is to walk through what happens after a typical high-carbohydrate meal.

Imagine breakfast as a couple of slices of white toast with jelly. The bread and the added sugar both break down quickly. Your blood sugar rises rapidly, sometimes to very high levels, especially if you are already a bit insulin-resistant. In response, the pancreas releases a significant amount of insulin to clear the sugar out of the bloodstream and into muscle, liver, and fat cells.

Insulin sticks around longer than the sugar spike. As insulin continues to drive sugar out of the blood, your levels drop – not just back into the normal range your brain likes, but often below it. Once your brain senses that blood sugar has fallen past its comfort zone, it interprets this as an energy deficit and sends you looking for more quick fuel.

That is the moment when cravings hit. You feel like you “need” more sugar or starch. So you go back to the pantry or the break room and repeat the cycle.

If you do this day after day, insulin becomes a constant presence. The more you flood your system with insulin, the less sensitive your cells become. This is insulin resistance. Over time, your pancreas has to work harder to move the same amount of sugar. Eventually, it cannot keep up, and your average blood sugar starts to rise.

This is the road to type 2 diabetes.

We see a parallel in agriculture. How do we fatten livestock before slaughter? We confine them, minimize movement, and feed them grain. They stand still, eat high-glycemic feed, and become metabolically sick and obese very quickly. At a biochemical level, many humans are doing a similar thing to themselves – just with nicer branding on the packaging.

Facing My Own Genetic Risk

When I moved into age-management medicine and took full advantage of the diagnostic tools we use at Cenegenics, I learned something important about myself.

Genetically and by family history, I carry a high risk of metabolic syndrome and type 2 diabetes. My father and grandfather both became overweight and ended up on insulin. My genomic analysis shows multiple variants that predispose me to insulin resistance, obesity, and type 2 diabetes. I also carry APOE-related risk for dementia.

On paper, I could easily have been that 61-year-old who is overweight, hypertensive, insulin-resistant, inflamed, and quietly building vascular disease and cognitive decline.

In reality, I have none of those conditions. My body composition is optimized. My blood pressure is normal. My average blood sugar is low. My inflammatory markers are essentially zero. The only piece that reflects my genetics is a tendency toward less favorable cholesterol particle patterns, and even that risk is mitigated by everything else I do.

The difference is not luck. It is strategy and consistency.

Rebuilding My Nutrition and Movement From the Ground Up

The core of that strategy is simple, though not necessarily easy.

I stopped treating grains and refined carbohydrates as the base of my diet. Instead, my nutrition now focuses on whole foods that do not drive huge sugar and insulin swings. My plate is built around proteins, healthy fats, and lower-glycemic vegetables and fruits, with an eye toward micronutrients and satiety rather than pure calorie counting.

I also pay attention to when I move. I am intentional about getting up and moving – often just a short walk – after I eat. That small habit dramatically improves how my body disposes of glucose, lowers post-meal insulin stress, and makes it easier to stay lean over time.

Resistance training remains non-negotiable. I do not train for hours a day. I train for minutes a day, but I train consistently. Maintaining and building muscle mass is part of my metabolic insurance policy. Muscle is not just about aesthetics; it is a glucose sink, a protective organ, and a critical component of healthy aging.

On top of those foundations, I layer hormone optimization and targeted supplementation that is personalized to my labs and genetics. These elements do not replace nutrition and movement. They enhance my ability to carry out the lifestyle prescription and recover from it.

What We Teach at Cenegenics – and Why It Works

Most patients who come to us have tried at least one diet and often many. They have been told to “eat less and move more.” They have been handed a generic low-fat meal plan or told to follow a resource that was never designed for their unique physiology.

At Cenegenics, we start from a different place. We look at your biomarkers, your body composition, your cardiovascular capacity, your genetics, your sleep, your hormones, and your history. Then we build a nutritional strategy that respects your biology instead of fighting it.

We teach you why controlling insulin matters, why certain carbohydrate patterns trigger overeating, why muscle is part of your metabolic health, and why short movement after meals can be so powerful. We show you how to eat in a way that works in the real world and can be sustained over years, not weeks.

When you combine that with hormone optimization and smart exercise programming, something important happens: you feel better. When you feel better, compliance stops being an act of willpower and becomes an act of common sense. The “snowball” of positive change starts rolling downhill.

That is how someone with my genetic and family risk profile ends up with none of the diseases he was statistically supposed to have.

From Disease Management to Health Creation

In the traditional medical model, we wait until blood sugar is high enough, arteries are stiff enough, or symptoms are severe enough to justify a diagnosis and a prescription. That model is good at managing crises, but it is not designed to build health.

What we are doing in age-management medicine is different. We are not waiting for the heart attack, the stroke, the dementia, or the diabetes. We are reading the early signals in your labs, your genetics, your body composition, and your performance metrics.

Then we use nutrition, movement, hormones, and supplements to change your trajectory.

The old food pyramid and its modern descendants did not save us. For many, they accelerated the very diseases we are now trying to avoid.

Relearning nutrition – and aligning it with how your body actually works – is not just a vanity project. It is one of the foundations of a longer, stronger, clearer life.

That is what we are building at Cenegenics. And it is absolutely within your reach.
