Machine learning research links insulin resistance is linked to higher risk across at least 12 cancer types, positioning metabolic dysfunction as an early warning signal rather than a late-stage problem.
Dr. Mercola's article highlights the serious risk of insulin resistance and cancer, and we also know the implications of insulin resistance in metabolic diseases in general, such as neurodegenerative and cardiovascular diseases, a true pandemic of the 20th century.
Insulin resistance (IR) is increasingly recognized as a significant factor for cancer development and progression. While the triglyceride-glucose (TyG) index and its derivatives (TyG-BMI (body mass index), TyG-WC (waist circumference), and TyG-WHtR (waist-to-height ratio)) have been developed as reliable and straightforward surrogate tools for reflecting IR status, their comparative associations with pan-cancer incidence and mortality remain unclear. This study aimed to systematically evaluate the associations of these four IR-related indices with pan-cancer incidence and cancer-specific mortality in a large prospective cohort.
IR-related indices, especially TyG-WC, are significantly associated with both pan-cancer incidence and cancer-specific mortality. Compared with TyG, TyG-BMI, and TyG-WHtR, TyG-WC demonstrated stronger associations, suggesting its potential utility for stratifying cancer risk and prognosis in clinical and public health settings.
At the end of 2025, I had a blood test, and my results were: fasting glucose 75, fasting insulin 2.1, and triglycerides 92. An ultrasound and liver elastography revealed a normal liver (no fatty liver or fibrosis).
Your value: 63 → correct (efficient without hyperinsulinemia)
5. TyG index (indirect hepatic marker)
TyG=ln (Triglycerides ×Glucose / 2= 92x75/2= 8.15 close to optimum
< 8.0 → optimum
8.0–8.5 → intermediate
Greater than 8.5 → risk
CONCLUSION:
Exceptional insulin sensitivity
Very efficient metabolism
Low pancreatic load
Low metabolic and hepatic risk
Hepatic risk: very low
Profile compatible with good mitochondrial function and low inflammation

This review draws attention to the link between IR and BC, particularly in post-menopausal women. According to the literature, IR, often associated with obesity, T2DM, and inflammatory mediators released from adipose tissue, is linked to both the occurrence and progression of BC. Mechanistic studies provide further evidence that hyperinsulinemia and dysregulated insulin/IGF signaling contribute to BC development by promoting tumor proliferation, survival, and progression. Given that both lifestyle and pharmacological insulin-sensitizing interventions (e.g., structured physical activity or metformin therapy) have evidence supporting improvements in metabolic health and BC outcomes, further study is warranted.
IR is clinically relevant not only for metabolic disorders but also for determining the prevention, prognosis, and treatment of BC. Future studies should help clarify the value of evaluating IR markers such as HOMA-IR and the TyG index to enable early identification of women who may be at high risk for BC and consider tailored prevention and treatment options. Because IR is modifiable through lifestyle and pharmacological interventions, the management of metabolic health in BC has the potential to serve as an inexpensive and practical approach to minimize the risk of recurrence and the morbidity burden among BC survivors. The clinical and research community is urged not only to recognize the metabolic aspect of BC but also to incorporate strategies to improve insulin sensitivity into prevention and overall cancer care. Identifying and targeting IR as a modifiable risk factor creates an avenue to connect metabolic health and oncology to improve patient outcomes.

This "selective IR" favors triglyceride accumulation in hepatocytes.
In adipose tissue, IR attenuates insulin-mediated suppression of lipolysis, increasing circulating free fatty acids (FFAs). Excess FFAs are transported to the liver, saturating oxidative and export pathways and increasing lipotoxicity. Simultaneously, inflammatory adipokines (leptin, resistin) and infiltrating macrophages reinforce systemic and hepatic inflammation, further impairing insulin signaling. Therefore, insulin resistance (IR) not only promotes lipid accumulation but also establishes a pro-inflammatory and pro-fibrotic environment that accelerates progression to mastitis and fibrosis. Taken together, these IR-driven mechanisms link systemic metabolic dysfunction with organ-specific pathomechanisms in mastitis and liver disease (MASLD). They illustrate how altered insulin signaling contributes not only to lipid accumulation but also to inflammation, oxidative damage, and fibrosis, reinforcing IR as a central orchestrator of MASLD progression, as depicted in Figure 1. The schematic in Figure 2 and Table 2 highlights the interconnected mechanisms linking systemic metabolic dysfunction with hepatocellular carcinoma (HCC). Insulin resistance and lipotoxicity promote chronic inflammation, oxidative stress, and mitochondrial damage, while gut microbiota dysbiosis amplifies immune activation via lipopolysaccharides (LPS) and altered bile acid signaling. Genetic and epigenetic alterations further destabilize genome integrity, facilitating malignant transformation. Unlike tables summarizing individual determinants, this figure provides a visual map of how these processes converge to create a pro-tumoral microenvironment, connecting molecular insights with clinical outcomes.

For decades it was promoted a calory is just a calory and it didn't matter what we ate and it didn't matter how or when we ate.
Well said, Just, highlighting the corruption in the ultra-processed food industry and its regulation. There is excessive influence from ultra-processed food manufacturers on committees that advise politicians. They participate in high-profile health promotion campaigns while simultaneously lobbying against regulatory measures. It is suspected that this reluctance to act extends beyond regulatory bodies, reaching the medical profession and healthcare systems. The ultra-processed food (UPF) industry is “replicating the political strategy used by tobacco, alcohol, and fossil fuel companies” to try to influence government policies, experts warn. Global experts are calling for urgent measures to curb the growing consumption of ultra-processed foods. “Only by combining stricter regulation of low-quality food products with realistic support for more nutritious options can we truly promote better diets for all,” said Gyorgy Scrinis, Associate Professor, Faculty of Agriculture, Food and Ecosystem Sciences, University of Melbourne. “This shift in eating habits is driven by powerful global corporations that generate enormous profits by prioritizing ultra-processed products, supported by extensive marketing and political lobbying to stifle effective public health policies that promote healthy eating.”
Urgent public health measures are needed to promote healthy eating habits and reverse the rising consumption of ultra-processed products. Changes to food labeling are essential, and we call for public health interventions to combat and minimize the consumption of ultra-processed foods. These interventions are especially vital for socioeconomically disadvantaged populations and children, who are increasingly consuming ultra-processed foods as attractive and cheaper alternatives to fresh produce. Urgent action is needed to promote healthier eating practices worldwide.
It is alleged that companies They knew their products were addictive and harmful, but promoted them as healthy. A massive lawsuit filed in late 2025, with updates in April 2026, is against Nestlé, PepsiCo, Coca-Cola, Kraft Heinz, Mondelez, and Mars. The central argument is that these companies used deceptive practices to conceal the fact that their ultra-processed foods alter metabolic and neurological mechanisms (addiction).
Lawsuits for childhood illnesses: Legal proceedings have been initiated linking the consumption of these foods to type 2 diabetes and non-alcoholic fatty liver disease in children, accusing the companies of failing to warn about internally known nutritional risks.
A recent report in The BMJ (April 2026) reveals how the food industry managed to reduce the scope of new nutrition labels in Canada after years of persistent pressure, obtaining exemptions for products that should carry "high in sodium or fat" warnings.
In several countries, the committees that draft public health guidelines have been criticized for having Members with direct financial ties to manufacturers of ultra-processed foods weaken warnings about consuming these products.
A March 2026 report revealed that more than 100 food chemicals entered the U.S. food supply without FDA review, exploiting loopholes that allow companies to declare their ingredients as "generally recognized as safe."
