is a whole other level of complexity but doesn't invalidate my statement. Also if we are being nitpicky your comment about insulin "causing" weight gain is silly. It isn't as if giving someone insulin will cause their bodies to defy the laws of physics. The reason that most people gain weight when they start insulin is that once insulin therapy begins and blood glucose levels come down towards normal, the excess urination and loss of glucose through the urine comes to a stop. Our cells resume storing all of our food in the form of fat or glycogen, and our weight returns to a level that is appropriate for our food intake and calorie expenditure. In other words, insulin simply restores healthy blood glucose levels and allows us to weigh what we should based on our diet and exercise patterns.
