I've done Anabolic Diet in the past with limited success. It tends to be a little easier than the others to follow since it doesn't really have set times or amounts to follow. I'd call Anabolic Diet modified Atkins, or cyclical keto. The problem I ran into was not knowing how much to eat on carb loading days. While it worked in the beginning, after awhile I found I was just spinning my wheels, couldn't get past a certain weight.
BodyOpus is a GREAT read and Dan writes it in a manner that makes it easy to read. Great for getting the concepts and learning the how's and why's, but it's out-of-date. It's a pretty strict diet when you break it down, I'm not sure I could recommend this to anyone starting out. I highly recommend reading it though, just to learn of things like glycogen depletion, supercompensation, and such is worth it all.
Ultimate Diet 2.0 tends to be a mix of AD and BO but more up-to-date. It's a strict diet as well, but not quite as strict as BO. Honestly, if you learn about BO, you have to read UD2 to update it. I like some parts of UD2, again the information is invaluable, but I think it needs a little updating as well. I would say this diet probably works the best but needs to be updated, modified or mixed with BO. Not sure I could suggest BO or UD2 for starting out.
My personal experience (also having lost lots of weight) is that strict cyclical keto diets aren't very helpful and can be mostly counter productive until you get closer to 20-25% bodyfat. You'll lose the most weight on straight keto without losing much muscle. If you don't lift often, you probably won't lose any muscle and will even gain some in the beginning. As suggested before, I'd probably throw a carb loading day similar to BO or UD2 in once every month. You'll find on straight keto you really start to slow down after a month and a carb load day will not only replenish you mentally, but can really kick off the weight loss again. High protein keto diets are easy to follow and produce OK results (to a point), but high fat keto diets will produce more weight-loss. They're not as easy to follow.
