I never said you'd lose three days of weight progress, I said it would take three days to get back into ketosis, as that is the average time it takes for the metabolism to change up it's preferential fuel, again. That is completely independent of what your weight may actually be doing.
I highly, HIGHLY suggest you read up on ketosis and get your hands on as much information as possible, as you seem to be doing a diet without understand the nutrition or physiology involved in it. Atkins New Diet Revolution is good, the Perfect Health Diet is excellent, many different ways of eating utilize ketosis or ketogenic fasts and explain the science behind it (or in the case of the Perfect Health Diet, why you may not want to persist in long term ketosis unless the health benefits outweigh the disadvantages, it depends on the person).
Do a bunch of reading and pick a plan. If you want to stick to Ideal Protein then do, but do stop wasting money to have someone berate you instead of educating you. I'd say 90% of the successful maintainers around this site, myself included, are doing free programs with no centers or support. There's some weightwatchers, JC/nutrisystem peeps, and yes, IP. But I don't think it is a coincidence that those who are keeping it off aren't paying for food or support. Just something to think about
