I had the same problem. I think the missing piece of the puzzle for me was this part:
I should have mixed it up some, a "carb refeed" I guess. I was just doing it for too long of periods at a time, I think.0-50 grams per day: Ketosis and I.F. (Intermittent Fasting) zone. Excellent catalyst for rapid fat loss through I.F. Not recommended for prolonged periods (except in medically supervised programs for obese or Type 2 diabetics) due to unnecessary deprivation of plant foods.

So it wasn't until I read this for like the 6th time, that it finally sunk in. (and then later re-reading some of Mark's advice and some of the posts here, were saying the same thing. Just not sinking in)

So I have switched my macros around, mostly to a 3 way split, but no more than 40% fat. It is working for now. I do go lower carbs on some days, like earlier this week I thought it would help me get my Thanksgiving water off, and it did.
But from CW dieting to primal, or 30% fat to 60% fat, the weight loss cut in half. BUT... I was full and more satisfied, and no longer going to bed hungry every.single.night. And I was learning lots of valuable information. But the higher the fat, the slower the weight loss, and then a gain around 85%. So it might not work so well for me to lose the weight, but it is nice to know that I can eat that way and not gain so it will be good to know for maintenance
And it didnt really seem to matter where my calories were. In fact perhaps they might have been chronically too low. I still dont know how I feel about that science yet. Some ppl fast for long term and still lose weight, so I dont know. But just seems like when most of my calories come from fat, however many calories that might be, when they come from fat, my weight loss slows to stops.
Mostly the only thing I had to do to hit these macros, was to cut out the extra fat. Not avoiding fat in meat, etc but the extra fat - Like the butter on top of the steak. I also added in starchy carbs. I just don't eat them with butter and sour cream or cream cheese.
