Insulin Resistance
A state where cells respond poorly to insulin, forcing higher levels — the engine of prediabetes and a brake on fat loss.
In insulin resistance, muscle, liver, and fat cells grow deaf to insulin's signal, so the pancreas shouts — producing more — to keep glucose controlled. Blood sugar can look normal for years while insulin runs high, quietly promoting fat storage, driving post-meal energy crashes, and straining the pancreas toward type 2 diabetes.
It is both cause and consequence of weight gain, which makes it the loop worth breaking. Weight loss, resistance training, sleep, and fiber all improve insulin sensitivity; GLP-1 and dual-agonist therapy improve it directly and via weight. For many patients, "insulin resistance improving" is the lab-report translation of why the same effort finally produces results.
