Insulin is responsible for maintaining stable blood sugar levels by telling the body’s cells when
to absorb glucose from the bloodstream. Being
insulin resistant means your body stops responding to insulin, and instead grabs every calorie it can and deposits it as fat. So no matter how little you eat, you will gradually gain weight.
At the same time, your cells cannot absorb the glucose they need, so they signal your brain that you need more carbohydrates or sugars.
