5 Major Causes of Insulin Resistance Revealed: Avoid Diabetes Risk Now

• Dr. Sudhir Kumar identifies 5 key, largely reversible causes of insulin resistance, a major driver of Type 2 diabetes.
• Belly fat, specifically visceral fat around organs, disrupts insulin signaling, even in seemingly thin individuals.
• An inactive lifestyle reduces muscle glucose absorption, forcing the body to produce more insulin and leading to resistance.
• Ultra-processed foods and high-glycemic carbs cause rapid spikes in glucose and insulin, damaging receptor sensitivity over time.
• Lack of sleep and chronic stress elevate cortisol, impairing insulin sensitivity; genetic factors also increase risk, especially for South Asians.
