Obesity police

In all the articles and propaganda I have read about obesity in children, there is one word that has been conspiculously absent: parents. Shouldn't the PARENTS be responsible for their children's weight? Aren't THEY the primary caregivers their first 5 years? The articles all act as if the kids become 200 pounds overnight. Where are the parents? Stop blaming vending machines and fast food, and start making the parents responsible for a change.
