There seems to be a great deal of energy being spent in this thread attempting to show that people can lose weight if they just eat less and move more. I'm certainly not going to argue against that, as it is most obviously true.
However, something I'm not seeing addressed much here is that there is a $160 Billion industry spending approximately $5 Billion/year to convince Americans that they should eat MORE fast food. Counter to the $116 Million spent advertising fruits and vegetables. Every one hour of television, (on most channels) contains 21 minutes of ads offering enticing fast food and crap food,
Don't you want tacos right now? How about these crackers? Doesn't a pizza sound good? Crunchy crunchy chips! Our fried chicken is the best! Oooooohhh Ice cream!! $5 Foot longs! And the calorie content of these fast food meals has gone up year by year. Burgers are bigger, the size of the fries gets larger, the pizzas get heavier each year with more toppings and more cheese. (Some of which is due to help and encouragement from our own US Dept of Agriculture:

Add to that the proliferation of frozen ready meals available at the average grocery. Not only can you get PF Changs entrees, or TGIF loaded potato skins, or name brand pizzas in the freezer aisle, the deli now is filled with cooked and ready to eat meals, almost all of which are designed from a seller's point of view, meaning full of hidden fat, salt and sugar, which people gobble up, that are certainly not “healthy alternatives”, even though it's easy to think that they might be better for you. All of these options get extra end space, extra advertising, and better placement in the store in order to make sure people notice them, because there's bigger money in advertising and more profit for the grocers in selling them vs regular old raw meat, fruit and vegetables. Even good old milk is doing its best to make us all just a smidge fatter by offering all sorts of sweetened and flavored products.
I don't think too many people would argue that the better funded campaign usually wins in this country. As I said above, there's almost Five Billion Dollars being spent advertising fast food. Not counting the chips, crackers, sweets and snack food industry, which are all pushing their own version of high calorie low nutrition snacking.
The question is, How does one counter this campaign? Are we really expecting the 70% of our population that is overweight to just individually choose to ignore this constant barrage of messaging and suddenly choose healthy eating? And succeed? Can someone provide an example of any time Billions of dollars were spent on any kind of messaging campaign, but the majority of Americans ignored it or chose against it?
Again, fast food is a $160Billion industry. The entire weight loss industry, including diet books, diet drugs, and weight loss surgeries is $20Billion.
Where and how is this Eat Less Move More message to compete with that?
I'd also like to add that we are working longer hours and have less free time, and that constant budget cuts and higher testing requirements in our schools are making more and more schools reduce PE and recess time, as well as eliminate some after school sports.
