I stayed on Induction for about six months, and would have done it for longer but I had an unrelated health problem, then a bunch of travel afterward. I lost about 60 pounds during that time.
Then I lost about 20 more, then I added more carbs for a few months, but stopped losing. A couple of weeks ago I went back on Induction, and now I have lost three pounds (I haven't been as strict as I was the first six months I did it, but I am not trying to lose as fast as I did then). I still have 30 - 50 pounds to lose (haven't decided on a final goal yet - my intermediate goal is 15 more pounds for nice ROUND number of 100 pounds lost!)
You are doing great - keep up the good work!
