Insulin is secreted every time you eat. It's not a bad thing, it's a very fundamental part of regulating your blood sugar. (Ask someone with type I diabetes -- it's a royal pain to control blood sugar manually.) It's released whether you're active, sedimentary, eating a healthy diet, or junk food. When you eat breakfast in the morning, you're most certainly replenishing glycogen. While you sleep, it's the primary source of blood glucose. Your body will prefer to replenish the glycogen before beginning lipogenesis.
