Do you always feel hungry, no matter what (or how much) you eat? Constant hunger can be a sign of insulin resistance. When your blood sugar levels are too high, your pancreas produces more insulin in an attempt to get the insulin out of your bloodstream. But when too much insulin bombards your cells, you can develop insulin resistance. Other symptoms include intense carb cravings, difficult losing weight, and always feeling tired after meals.
