America is getting fatter... advocates predict that more than half in 39 states will be obese by the year 20-30.
but regulators are hoping changes in the way food is marketed will help americans lose weight.
NBC's Brian Burnell reports.
According to yale university's rudd center for food policy and obesity, over 2-thirds of americans are overweight or obese.
in an effort to help the american weight problem mcdonald's has decided to start listing calorie information on menus in 14-thousand restaurants.
a new law requiring that takes affect next year and mcdonald's is getting a head start.
and in new york the board of health has voted to ban the serving of sugary drinks in containers bigger than 16 ounces over the objection of some.
Eliot Hoff, new yorkers for beverage choices: "we do not believe that restricting the size of one product in certain establishments in the city is the comprehensive approach that we need to deal with this issue."
the ban applies to ballparks, restaurants, movie theaters and food trucks and its something mayor michael bloomberg has pushed.
Mayor Michael Bloomberg, (R) - New York" "this is the single biggest step any city i think has ever taken to curb obesity."
but will it work? will posting calorie counts and banning big gulps really help americans lose weight?
Kelly Brownell, Rudd Center Director: "we don't know specifically whether these things will work until they're tried."
kelly brownell is the director of the rudd center. he says there are some studies that suggest moves like these may be effective.
Kelly Brownell, Rudd Center Director: "one thing that's nice is that different cities and states are trying different plans and this provides lots of natural experiments that you can use to converge on a small set of bets practices."
and, he adds, the conversation alone is healthy.
Kelly Brownell, Rudd Center Director: "people are paying more attention to the obesity problem and at all levels of government officials are now thinking what can we do, what should we do, what do we need to do in our locality and those conversations will lead to good things."
