Having not viewed this book, it's hard for me to comment, but...
Just in general, "carbs are not inherently bad." There are "good" carbs - the complex carbs found in whole grains, fruits, veggies, beans, legumes... these kind of carbs are necessary for good health. Then you have the "refined/processed" carbs - the sort of stuff like candy, white bread, french fries, soda - that tend to be "empty calories" and which north americans tend to eat in excess, that have given "carbs" as a food group, kind of a bad rap.
If the book focuses on vegetarian/low-meat recipies, these WILL be higher in carbs. Because non-animal protein has to come from plant sources, which - contain, carbs.
It is a myth that "eating too many carbs will give you belly fat" - too many CALORIES will plump you up, but it doesn't really matter if you overconsume on fat, protein or carbs. Too much is too much. It's just that the "typical north american diet" is VERY carb-centric, the "addictively appealing fast foods and processed snacks" are VERY carb-centric. So it gives the appearance that carbs are the culprit - when really, the culprit is simply "excess."
