I don't think there is an easy "sugarless kid equals bingeing adult" rule thingy. I think it depends a lot on what else was being cooked in the house and the emotional conditions at mealtimes, the teachings (overt and subtle alike) of the parents on body image and nutrition, any food allergies or intolerances and how those are handled, peer and media pressure as it relates to food and "treats", and the individualness of each kid in personality and metabolism and tastes in food... So - lots of variables.
In your case, I think Primal is helping because you are finally getting truly nutritious food, eaten joyfully, that is delicious. All three are important in the food and nutrition training of a kid. Pass that on to your kids, and they won't have the same negative food attitudes as you did, which can only benefit them!
I have a mantra that I have spouted for years... "If I eat right, I feel right. If I feel right, I exercise right. If I exercise right, I think right. If I think right, I eat right..." Phil-SC
