Too many carbs is bad, but zero carbs is counterproductive too. The goal is to get some protein and some carbs, but fewer carbs when you are losing and not exercising enough for your body to turn them into energy right away.
If you are eating a lot of fruits & vegetables and exercising, then a serving or two of rice and beans eat day will be used as your body needs to and the calorie reduction will take care of the weight loss.
