You don't really need a book. There is so much information available on the internet. First off, you need to be sure you know what a carb is. My BIL's doctor told him to cut back on carbohydrates but he doesn't know what a carb is. Everything he eats is a carb.
I would start out cutting back on sweets, bread, pasta, rice, fruit, the obvious starchy carbs and drink a lot of water. If you can comfortably start at 100 gm an day, do that and see if you start to lose. If, not, cut back by 10 grams at a time, until you find the level where you can lose, but not feel deprived. Everyone is different and everyone will lose at a different carb count.
IF not now, when?
