Your goal should be to reduce your insulin resistance, and improve your insulin sensitivity, by getting the fat out of your cells. Hopefully, you are already aware that insulin resistance is caused by extra fat in cells that are not designed to store fat, primarily muscle and liver cells.
What you are seeing is result of your insulin resistance. This is to be expected. It will reduce and disappear as the insulin resistance goes away. Don't expect to see this immediately. This could take months. But you should be seeing progress in weeks, including weight loss and normalization of blood pressure and blood cholesterol, for example.
