I have borrowed this book from the library and had to return it two weeks ago because someone else had it on hold. Please someone, help me remember how to calculate carbs. I do remember the book saying to take the carb grams and divide by 4 to know how many teaspoons of sugar eaten per day.  What I don't remember is if under the total carbohydrates is dietary fiber grams and sugars subtracted from the total or only the dietary fiber?
