If you want to help control obesity. Just stop buying the damn junk food no matter the price or tax on it. Eat your F'N veggies, fruits and lean meats. Do some REAL work and exersize. Get outside and play with your kids or grandkids, play some sports, go for a hike, ride a bike. Lead by example and set the guideslines for our youth, I didn't eat all that crap as a kid and neither does my son now. Sure he gets some candy, cake and ice cream eveynow and then but not junk eveyday. He won't even touch soda. Best thing I can say is get off yer a$$ and stop putting that crap in your face.
