 carbon hydrates are an important source of energy, but if you eat too many carbs, it can leads to health problems like obesity¹. that issue is the focus of this week's weight of the nation conference. A new report was released² at the meeting, it estimates³ that by the year 2030 42% of the US population will be obese⁴. that's 30 million more americans than right now.  the medical cause associated with that increse would total up to nearly 550 billion dollars. Solida? Obrian talked with CNN's doctor Sanjay Guteb about some of the reasons behind this issue. 

Sanjay before we get to the numbers explain to me why are we getting that fat so quickly? 

well, you know, if there is any good news in this and i'm not sure there's a lot ??.  the number are actually originally? expected to be worse. they said 51%, at one time they predicted, of the nation would be obese. this is adults by the year 2030. so 42% is still nothing great obviously⁵. 11% they think will be severely⁶ obese. look, So?? you'll hear a lot of the same sort of things you've heard for some time, i mean you've been covering this for a long time, as have i, too many fast food restaurants too inexpensive to get unhealthy calories, there's not enough park , too many roads. all those things that keep coming up and despite the fact that those messages have been heard and understood problems just keep getting worse. i think, you know, there's a lot to, at the individual level, i think simple things can help, you know, simply eating more food in the morning they find, they getting up and walking around, but i think there's a larger problem. and that is, it's just not how much we eat but what we are eating as well, you know, sugar for example, just give you a quick example probably behaves differently in the body than just about any other calory, makes you gain weight but also creates these lipids?? that are really bad for the heart raises insulin levels that makes you store even more fat. so for a long time we thought health food for example were low fat high sugar foods. and as we became that country that eat that kind of diet the problem just became even worse. 

All right you heard dr. Gu?? talked about some ways the individuals can work to prevent obesity. at the weight of the nation conference experts had some other ideas, some other solutions. some of those include a shift⁷ in foreign polycies, so there's more focus on fruits and vegetables. there's also a suggestion for a possible tax on sugary drinks though there are some controversy⁸ associated with that. another idea is to start the fight against obesity at school. for instance⁹ requiring schools to provide an hour of physical education or activity everyday. 

now picture this scenario¹⁰ your team is moving through a building the possibity of danger all around, you need to complete your objective¹¹ to get everyone out safely sounds like a video game it's also a situation that firefighters rutinely find themselves in. brook¹² Bal?? explains how new technology can help them.
