Fat Loss 4 idiots is one of the more popular e-books out there on fat loss. I haven't read it, however, all successful fat loss programs have some things in common:
Sugar and grain addiction has to be addressed.
There has to be adequate protein.
Good fats need to be included.
Refeeds need to be built into the program.
The fat loss program needs to include resistance training and should not rely on excessive cardio.
I beleive if you have all those factors covered in your program, you will be lose fat, you will feel healthier and you will have no trouble staying with the program, and you will build habits you can live with for a lifetime. If you are missing any of these factors, you will fail.
I wouldn't suggest that you not read the book, as all reading is useful, however, you may be better off to visit your library and check out what's there fo free. There is a book list on this forum somewhere. Books I've read that I have found helpfual are:
"The Metabolic Advantage" - Berardi
"TNT Diet" - Volek
"Paleo Diet" - Cordain
"The No-Grain Diet" Mercola
