Overly high blood sugar levels can also cause rapid weight loss, say 10 to 20 pounds over two or three months—but this is not a healthy weight loss.

Because the insulin hormone isn't getting glucose into the cells, where it can be used as energy, the body thinks it's starving and starts breaking down protein from the muscles as an alternate source of fuel.
