Agreed.  I've been there, my parents aren't obese (my mom is most likely in the "overweight" BMI category) and they never did it intentionally but I always had a sweet tooth.  I was never educated about this sort of thing, and I was a latchkey kid so the afternoon snack for me was a few oreo cookies.  The best part is that my family had close ties to the Great Depression and were raised that way, both my father and mother came from somewhat low income families, so "finish all the food on your plate or no dessert" was the mantra.  Did more harm than good, and to this day, 20+ years later, I just CAN'T throw food away.  It's one of the hardest things I do.
