An Engineering Guide to Chronic Disease Avoidance
Ivor Cummins
Ivor Cummins BE(Chem) CEng MIEI PMP® completed a Biochemical Engineering degree in 1990. He has since spent over 25 years in corporate technical leadership and management positions, with a specialty in leading large worldwide teams through complex problem-solving activity. Since 2012 Ivor has been intensively researching the root causes of cardiovascular disease, diabetes and obesity. He now entertains and informs laypeople and medical practitioners at health conferences all over the world. Ivor’s recently published book “Eat Rich, Live Long” (co-authored with preventative medicine expert Jeffry Gerber MD, FAAFP) covers the gamut. It comprehensively addresses the actions needed to reverse our modern disease epidemics. Ivor lives in Dublin, Ireland, with his wife and five children.
The aim of this talk is to give a high-level overview of heart disease and other chronic condition root causes. It will also zero in on who is really at the greatest risk, and needs to take the most decisive actions to avoid heart attack or an early death. How do we identify and save these people? Luckily there is a science-based strategy to do so. It's not too hard to achieve it either - but only when you know how.
If you don't measure it, it doesn't get fixed. Heart disease is resolvable, and you can live long and strong because it is a disease that you can impact massively with what you eat and how you live your life.
Summary
- Focus on root cause measurements rather than misleading markers like LDL; the coronary calcium scan is the most accurate predictor of heart disease risk and future mortality. - Insulin resistance and hyperinsulinemia are the primary drivers of modern chronic disease, yet they often remain undiagnosed by standard medical blood tests. - Metabolic health is determined by adipose tissue function rather than weight alone; many "thin outside, fat inside" individuals are at high risk due to inflamed visceral fat. - Prioritize a low-carb, high-healthy-fat diet of ancestral foods while eliminating refined carbohydrates, sugar, and industrial vegetable oils to stabilize arterial plaque. - Implement high-impact lifestyle interventions such as intermittent fasting, strength training, and optimizing levels of magnesium, vitamin K2, and vitamin D to improve insulin sensitivity.

An Engineering Guide To Chronic Disease Avoidance
At Biohacker Summit 2018 Tallinn, Ivor Cummins Delivered A Stark Message About The Diseases Modern Medicine Too Often Missed
On 15 September 2018, at **Biohacker Summit 2018 Tallinn** in **Tallinn, Estonia**, the engineer and health researcher **Ivor Cummins** stepped onto the stage with a proposition that was as provocative as it was methodical. Chronic disease, he argued, should be approached less like an inscrutable fate and more like a systems failure. The task was not to chase fashionable markers or vague reassurance. It was to find the root cause, measure it accurately, and intervene before catastrophe arrived.
His presentation, **“An Engineering Guide To Chronic Disease Avoidance: Root Causes & Measurement,”** was built around a simple but unsettling premise: millions of people were being told they were healthy while silent atherosclerosis progressed unseen.
The Case Against Comforting Numbers
Cummins framed his talk through the lens of engineering, where imprecise measurement is not a technical flaw but a pathway to disaster. In medicine, he suggested, the same principle applied. If clinicians measured the wrong variables, they could miss the process that actually killed people.
“**Focus on the best places where there is the biggest bang for the buck,**” he said. “**Twenty percent of the root causes in any particular problem will account for eighty percent of the improvement you can get.**”
For Cummins, that meant giving less weight to standard cholesterol readings, particularly LDL in isolation, and far more attention to direct evidence of arterial disease. His preferred instrument was the **Coronary Artery Calcium scan**, or CAC scan, a quick imaging test that can detect calcified plaque in the coronary arteries.
He described it as a Pareto-style diagnostic, inexpensive, rapid, and disproportionately revealing.
The Scan That Changed Everything
To make the point vivid, Cummins turned to the story of Irish businessman **David Bobbett**, whom he described as slim, active, and apparently protected by every conventional measure. Doctors had reassured him. Blood tests were unremarkable. Stress tests raised no obvious alarm. By mainstream metrics, he was low risk.
Then came the calcium scan.
In minutes, Cummins said, the test revealed a score of **906**, placing Bobbett among the worst affected for his age and indicating a dramatically elevated risk of heart attack or death in the following decade. It was a devastating contradiction of the medical comfort he had previously been given.
That, in essence, was Cummins’s indictment of current practice. The standard markers had not merely failed to predict danger. They had disguised it.
He offered a second example, a 42-year-old engineer named **Noel**, who had been told that his low cholesterol and normal blood work meant he had little to fear. Yet after pressing for a CAC scan against medical reluctance, Noel discovered that calcification was already present throughout his coronary arteries.
The warning was unmistakable. Disease could be advanced long before the body announced it in obvious symptoms.
Atherosclerosis As A Slow, Violent Process
Cummins described atherosclerosis not as a mysterious bolt from the blue but as a long inflammatory process inside the arterial wall. Early lesions, he said, begin as small disturbances that can gradually become enlarged, inflamed, and unstable. Over time, the body recruits calcium as a stabilising response, forming a bone-like matrix around dangerous plaque.
This matters because calcification is not random debris. It is evidence of an ongoing battle.
The tragedy, as Cummins presented it, is that the process often remains silent until rupture, clotting and infarction turn hidden disease into a public emergency. Half of those struck by sudden heart attack, he warned, may never stand up again.
And yet his talk was not fatalistic. If the process could be identified early, it could also be slowed or stabilised.
“**You can implement the fixes and stabilize your plaque so it is no longer growing,**” he said. “**It is the growth of the process that causes the events. By taking action, you can stay healthy and get to see your grandchildren after all.**”
Why LDL Was Not His Chosen Villain
One of the more combative moments in the presentation came when Cummins challenged the cultural dominance of LDL cholesterol as the chief object of cardiovascular fear. He did not argue that blood markers were irrelevant. Rather, he argued that many were misread and overvalued.
Using data he cited from population studies, Cummins noted that people with drastically different calcium scores could present with similar LDL values. In his formulation, this made LDL an unreliable standalone guide to actual disease burden.
“**Most markers on a cholesterol panel are actually being driven by insulin resistance syndrome,**” he said. “**It is not really a cholesterol thing at all, and that is one of the primary drivers of heart disease today.**”
The more powerful thread, in his telling, ran through insulin, glucose regulation, adipose dysfunction, and metabolic health.
The Elephant Disease Of The Modern World
If the scan was the instrument of revelation, **hyperinsulinemia** was the central culprit of the story Cummins told. He called it “the elephant disease” of modernity, the enormous pathology hiding in plain sight while public discourse remained fixated on fat, salt, grains and simplistic cholesterol narratives.
“**Hyperinsulinemic syndrome is the elephant disease of our modern world,**” he said. “**Two-thirds of older adults are now essentially diabetic, and this is completely preventable.**”
What made the argument particularly forceful was his insistence that metabolic dysfunction did not belong only to the visibly obese. Some of the most endangered people, he said, were those who looked healthy from the outside but were metabolically compromised within.
He described the now familiar but still poorly understood profile of the **“thin outside, fat inside”** patient: lean in appearance, but carrying inflamed visceral fat and disordered insulin signalling. These people could pass through ordinary screening largely untroubled while remaining at high risk.
Fat, Inflammation And The Body’s Hidden Threshold
Cummins gave considerable attention to the biology of adipose tissue, presenting body fat not as passive storage but as an active endocrine organ involved in complex hormonal crosstalk with the liver, pancreas and other systems.
The crucial distinction, in his account, was not simply between fat and thin, but between **healthy subcutaneous fat** and **inflamed visceral fat**. Some individuals, he said, could store excess energy relatively safely. Others crossed a “personal fat threshold” beyond which fat tissue became dysfunctional, inflammation rose, insulin resistance deepened, and chronic disease pathways accelerated.
In this framework, body weight alone became a poor moral and medical shorthand. The central issue was whether the body’s metabolic buffering system had begun to fail.
What Traditional Populations Seemed To Show
To argue that chronic disease was not an inevitable companion of ageing, Cummins pointed to ancestral or non-industrialised populations such as the **Tsimane** and the **Kitavans**. In the data he cited, these groups exhibited strikingly low levels of coronary calcification, low insulin, low glucose, minimal metabolic syndrome, and blood pressure that did not rise in the now familiar modern pattern.
The implication was not romantic nostalgia, but comparative evidence. If populations living under different dietary and environmental conditions experienced radically lower cardiovascular burden, then the epidemic seen across industrial societies could not be explained away as natural ageing alone.
The Prescription: Ancestral Food, Fasting, And Strength
Cummins’s practical recommendations were rooted in metabolic repair. He advocated a **low-carbohydrate, high-healthy-fat diet** based on ancestral or minimally processed foods, with the elimination of **refined carbohydrates, sugar, and industrial vegetable oils** taking priority.
He also endorsed **intermittent fasting**, **strength training**, and attention to nutritional status, particularly **magnesium, vitamin K2, and vitamin D**. Fatty fish and cod liver oil, he suggested, were useful tools for improving fatty acid balance and delivering fat-soluble nutrients.
The through line of the advice was not dietary purity for its own sake. It was the reduction of insulin resistance and the stabilisation of the metabolic processes that, in his view, were driving arterial injury.
A Test For Middle Age, And A Challenge To Act
The presentation ended where it began, with measurement. Cummins argued that men over **40 to 45** and women over **50 to 55** should consider CAC testing as a way to move beyond guesswork and identify real cardiovascular risk.
A low score, he said, could function as a kind of warranty. A high score, by contrast, demanded urgent and disciplined response.
“**If you find you have a high risk score, you have to do the job,**” he said. “**You have to do it for yourself, for your family, and for your future. It is up to you to take control of your health and find the root cause of your problem.**”
That final note captured the spirit of the talk at **Biohacker Summit 2018 Tallinn**. Cummins was not offering reassurance. He was offering a challenge: that modern chronic disease, especially cardiovascular disease, should be treated less as destiny and more as a measurable, modifiable system under strain.
Whether one accepted every plank of his argument or not, the power of the presentation lay in the unease it created. It forced a difficult question into the open. If the most dangerous disease is the one we fail to measure, then what else, in all our confidence, are we still not seeing?
