Do it. Our kids eat this way and they are calm and well-behaved and healthy and, best of all, not picky. If they eat too many carbs, they start having attention and behavioral issues and illness. In addition to eating Atkins and traditional foods (hopefull you are not planning on giving them Atkins bars), keeping to the Feingold diet principles can really help. The main ones we follow are no apples, no Red dye #40, low pesticide. We have a friend who is using this way of eating to gain weight and stabilize blood sugar.
