I didn't speed it up - it was fairly slow-going all the way. The thing is, after the first six months or so, it's pretty much slow-going for everyone, so after that point, we were all pretty much in the same boat. I just stuck to the plan, that's all. It came off slowly but surely. I almost never went off my plan - I suspect I was more compliant than a lot of others in my group, so I had great success with it (losing 100% of my excess weight). And yes - I did have two or three major stalls along the way (some people have more than that). My first one lasted two weeks (it was weeks 2 & 3 post-surgery. My weight loss started up again week 4 post-surgery - I dropped like 6-8 lbs within a couple of days, then the "slowly but surely" thing started up again). I don't remember how long the other stalls lasted - maybe 2-4 weeks? I remember thinking during those times that this was it, I wasn't going to lose anymore, but then....it would start up again.
I did work out (still do), but I'm not a gym rat. I mostly went to water aerobics a couple times a week and yoga a couple times a week. A lot of it was weighing & measuring my food, tracking, weighing myself several times a week, and not going off plan. I was determined to lose as much as humanly possible!!
