dr. thomas farley. thank you for coming in.his became public, and the biggest headline for those who criticize this idea is that this is just nanny nation, stay out of my business. why is anybody wrong to tell you to stop telling them what to do? >> any time you have a new idea it takes some time for people to adjust to it. we have smoke free bars and restaurants in new york city and don't have transfats in our food. we have a crisis in obesity in new york city and the nation as a whole and think putting a cap on the default size of sugary beverages makes sense. if people want more than that they can but the default size would be promoting of health than we are now. >> are you targeting the right thing? the reason i ask is because there's a cdc study that people tend to get small amounts of sugar from soda, less than 10% of sugar coming from soda so i sort of am curious about why you chose soda. look at the stats on the screen, kids between the ages of 2 and 19 are getting up to 8.2% from sugar and adults that goes up to 8.8%.

dr. farley did is they went right at portion size them said 32 ounces is ridiculous.is but a metaphor for what's important. >> is interesting when you know the the exercise and calorie because there's -- the traditional way of understanding, there's input and outputs and two sides of the lemoner in terms of obesity. one of the things we have seen is a shift in emphasis in michelle obama's campaign from food, from calories to exercise. and there is no stroint other side telling people to exercise. one of the things about big food -- >> yeah. >> one ways the couch industry comes up with ads -- >> barcalounger. >> i think it is critical. that is she looked at food as preventive medicine but include exercise. not very often do you hear the whole concept, that it is not -- stood necessary but not sufficient we need the other side of the coin, which has to do with the deficit. >> thank you for bringing are throw produce. >> the tray itself is the shape of the county. >> thank you, we will enjoy strawberries. >>> what we should know for the week ahead, right after this. i'm

dr. thomas farley was talking on "early start" to get more specific about the ban. >> there are a number over the last few years that demonstrate people are influenced by the portion sizes given to them. if you give people twice as much they'll consume more and won't notice and feel any different about it. if you give people a 16 ounce cup they'll probably consume less. the studies suggest this would have a big impact. >> mayor bloomberg downplayed the impact on msnbc, here is what he said there. >> we're not taking away your right to buy a soda in a supermarket, you can buy a 32-ounce can of full sugared drinks or bottle but in a restaurant they can't serve more than 16 ounces in any one cup. >> the other side comes from dr. rona applebaum, vice president of science and regulatory affairs for coca-cola. thanks for being with us. appreciate it. the mayor's point it sounds like, this is a policy that's intended to make people stop and think, not necessarily go with the big one if they want the big one or the equivalent of the big one they'd have to buy multiple sugary drinks or sodas. why
