Basically after phase 1 I eat carbs that are good for me. Whole wheat breads, crackers, popcorn, fruit, sweet potatoes, whole wheat pasta or multi-grain.
You just want to stay away from processed stuff that has no real food value and is loaded with sugar. Most healthy carbs are low in calories and high in essential fiber and protein. Healthy carbs also help your brain to function correctly and give you energy and stamina to exercise and function.
If you eat a carb and notice that it triggers cravings or makes you want to overeat then you should stay away from that food. Sometimes, not always, crackers, like triscuits eaten with a lowfat dip will make me tend to eat to many of them. Not always though. I just watch myself with it.
