#1 Most Important Test Your Doctor Refuses To Check

He argues that this test is the single most undervalued tool in preventive medicine. Because insulin is the body’s ‘key’ that lets glucose into cells, measuring it reveals how hard the pancreas is working to keep glucose normal. He shares that hundreds of his audience members have been denied the test or told it’s useless, reflecting a systemic blind spot. He sees it as a cheap, actionable marker that could slash the $5.6 trillion US healthcare bill if widely adopted.

He contrasts ancestral eating patterns (1–2 meals per day, infrequent insulin spikes) with today’s constant eating (3 meals + snacks + sugary drinks, 10–20 insulin spikes). This overload overwhelms cells, causing insulin resistance. Intermittent fasting mimics the pattern our bodies evolved for, giving cells a break from insulin. He says longer gaps between meals significantly drop insulin, allowing the body to tap into stored fat and break the hunger cycle.

He explains that the combination of sugar and insulin creates fat, especially in the liver. A low‑carb diet minimizes insulin spikes after meals, which not only reduces fat storage but also allows the body to access stored fat for energy. He notes that this approach works because it targets the underlying hormonal problem, not just calories.

He walks through the typical scenario: glucose stays within normal range (65–99) while insulin progressively doubles over years, keeping glucose controlled. A patient can appear “fine” for 20 years, then suddenly be flagged as pre‑diabetic or diabetic—the entire window for reversal has been missed. He highlights widespread doctor resistance, noting that hundreds of his viewers have been met with anger or dismissal when asking for the test. He contrasts the $5.6 trillion US healthcare spending with the $25–$35 cost of the test, arguing that widespread insulin screening could cut the bill dramatically.

He explains that glucose is a tightly controlled variable; the body prioritizes its regulation. Insulin can double or triple before glucose drifts outside the normal range. He gives an example: starting with glucose 85 and insulin 3, over years glucose creeps to 99 while insulin soars, but no red flags appear. Only when glucose hits 101 does a pre‑diabetes flag appear, and within 4–5 years full‑blown diabetes (126) occurs. This means that by the time glucose is high, insulin resistance has been damaging blood vessels, organs, and metabolism for decades. He argues that measuring glucose alone is ‘useless’ for early detection and that insulin testing would catch the problem when it’s reversible. He further notes that cardiovascular disease, cancer, dementia, and obesity are caused by insulin, not blood glucose, so glucose monitoring misses the root cause.

He details the mechanisms: (1) High insulin increases sodium reabsorption in kidneys, raising blood pressure, damaging vessel walls and kidneys, leading to kidney failure. (2) Chronic inflammation from high insulin directly damages endothelium, causing the body to send LDL cholesterol to patch rough spots, which over time forms plaques that can rupture (heart attack, stroke). (3) Insulin elevates fibrinogen and clotting factors, making blood stickier and promoting clots that cause heart attacks and strokes. (4) Insulin is mitogenic—speeding cell division—and suppresses immune surveillance (NK cells, T cells), increasing cancer initiation and metastasis, especially breast, colon, pancreatic. (5) In the brain, insulin resistance makes neurons deaf to insulin, starving them of glucose despite high blood sugar, leading to degeneration; it also increases beta‑amyloid plaques. (6) Osteoarthritis is worsened by chemical inflammation changing joint fluid chemistry and by obesity adding mechanical load. (7) PCOS arises from excess insulin raising testosterone, disrupting female hormones and fertility. (8) NAFLD is driven by de novo lipogenesis from sugar and insulin, creating fat in liver and fueling further inflammation and insulin resistance.

He likens high insulin to putting money in a vault and throwing away the key—every day, fat is stored and locked away. Because the body cannot access its stored energy, it signals hunger to get more fuel, creating a vicious cycle: eat more → more insulin → more storage/lock → more hunger. This makes calorie‑counting diets fail long‑term; the body fights against the deficit because the fat reserves are hormonally inaccessible. He argues that intermittent fasting and low‑carb diets succeed because they lower insulin, lifting the lock and allowing the body to burn stored fat.
