CAhardcore has it right your body needs carbs in a growth cycle. Of course you want to stay lean we all want to be lean but if your building muscle you need to be taking in more calories than your burning and clean carbs makes this easier, plus it gives you plenty of energy in the gym where it counts. So yes eat lots of brown rice, beans, legumes, etc and as was mentioned avoid the processed carbs like crackers, cereal, most types of bread even whole wheat if you can... watch out for high fructose corn syrups etc... read up on some of the site info especially the pre-cycle nutrition guide... cheers
