Te etiologiy of insulin resistance is beset understood as a convergence of genetic contributibility and powerful environmental triggers. Modern lifestyle, characterized by caloric excess, physical inactivity, and circadian distortionion, create a perfect storm that amplifies underlying risk factors. Each factor amplifies thee other, creating a feed-forward loop that acceletes metaboidic dekline.

Dietary Patterns andMacronutrient Composition

Refined Carbohydrates andd High Glycemic Load

Diets rich in raphine carbohydrates andadded sugars cause sharp postprandial spikes in glucose and insulin. Over time, these repeated glycemic exkursions desensitize insulitize receptors andd promote oksydative stres. High- glycemic- load diets are consistently associated with highier HOMA- IR scores and progrese incidence of type 2 diabetes.

Fructose andd De Novo Lipogenesis

Fruktoza, pyłowo-pyłowata, kiedy konsumuje się in high quantities from added sugars (sucrose and high- fructose corn syrup), bypasses the normal insulin-regulated steps of glucose metabolism. In te te liver, it potently stymulates dee novo lipogenesis, driving trigliceryde production, hepatic steatosis, andd VLDL section. Fructose-induced lipogenesis is a direct contrictor to the dyslippidemia ement of metaboyne syndrome.
