Granted this is strictly my opinion based on the advice of my own nutritionist, but some people's metabolism do need carbs. Carbs are energy. I just try to eat "good" carbs- like whole grain bread, whole wheat pasta, brown rice, and potatoes. I try to stay away from carbs that are white (except potatoes) or anything with the words "bleached" or "enriched" on the label. For me, it works.
