Hi WeeOne,
First of all I think it would be a great idea to read Protein Power. It has a lot of information you'll find useful.
However, I wonder if you are perhaps stressing a little unnecessarily about the fat with Atkins. Many of us find that we do best on 65-70% fat, but that is by no means necessary. In fact Dr Atkins never mentions how much fat, just carbs.
How many carbs are you having at the moment? By now, on Atkins you should be well past 20g. Did you know that a lot of people find their weight loss improves when they increase their carbs? Sounds odd, but it's true! And bear in mind that Protein Power starts on 30g. In fact there is not a huge difference between the two plans, other than the Drs Eades emphasis on getting sufficient protein.
Read the book, and see what you think. You sound as though you may be more comfortable with PP, and in that case, I'd say go for it!
As for your weight loss, you're actually doing well, believe it or not. It is very, very common, to plateau for about a month after an initial loss. It's unfortunate that LC is touted as a quick loss programme, because it is not unless you have a large amount to lose. From the stats here, most people (on whichever plan) can expect to lose 10% of the weight they wish to lose during the first 2 weeks, followed by 5 to 10% a month after that. And remember that this is now a way of life, not just a "diet."
I hope that helps you a little, Wee!
