Just keep doing the right things. Low carbohydrate, don't over-exercise, keep stress low, get plenty of sleep (up to 9 or 10 hours in winter) in a properly darkened room.... how do we break through?
For some people it seems to stop for awhile and then re-start. There's an interesting theory that this might be on account of trans-fats that they've eaten that can't be got out and burnt for energy, so that you have to wait for those cells to die. Maybe. At any rate, just keeping doing the right things seems to work for most people.
