Recently I was able to get back to weight-lifting at the gym. Back in March this caused my bg level to drop. 4 months and about 8lbs later, the exercise puts my bg levels up. But as I drop weight (mine not the exercise) the increase is gradually getting less. I put weight on around my waist first and this seems to be a good source for my liver to add glucose. I understand that the liver receives stimulation from the pancreas when glucose levels drop so part of this organ is working!
