It depends on the condition of the person. If the person is overly fat, I do not think it's necessary and the person can likely just drop fat by eating less with the same calories everyday. However, for the most efficient and fastest fat loss, then I say it's the thing to do.
You don't have to read tons of articles or books. Read a few articles and a book or two, and that's it! Get Shelby Starnes Carb Rotation e-book (I think it's ten bucks) or Tom Venuto's Feed the Muscle Burn the Fat (30-something bucks, I think) to get a rundown on how it's done. Or read an article or two from here.
I know you'd like answers, but if you want to do this on your own, it's going to take some initiative. Either that or you can pay someone to guide you through it.
What is your condition like now? Do you have a picture? What's your weight?
