ONE NEWS CAPTIONS BY CONOR WHITTEN AND TRACEY DAWSON. CAPTIONS WERE MADE POSSIBLE WITH FUNDING FROM NZ ON AIR. COPYRIGHT TVNZ ACCESS SERVICES 2013 DUE TO THE LIVE NATURE OF SEVEN SHARP, WE APOLOGISE FOR THE LACK OF CAPTIONS FOR SOME ITEMS. GIDDAY. WELCOME TO SEVEN SHARP. IT'S BOYS ONLY IN THE STUDIO TONIGHT. IF YOU'RE WONDERING WHERE ALI IS, SHE'S HAVING A NIGHT OUT AT THE VIADUCT. TEAM NZ IS LIFTING THE BOAT OUT OF THE WATER IN AUCKLAND TONIGHT AND PACKING UP FOR SAN FRANCISCO. ALI IS THERE TO HELP WAVE THEM GOODBYE. ALSO TONIGHT ` FIRST THERE WAS DRUG ADDICTION, THEN SEX ADDICTION, THEN INTERNET ADDICTION. BUT YOU MIGHT FIND THIS LATEST ONE A BIT HARD TO GET YOUR HEAD AROUND. FIVE YEARS AGO, WE WEREN'T CONVINCED. BUT NOW WE ARE. WE ARE CONVINCED. THE ADDICTIVE SUBSTANCE WHICH IS IN EVERY KIWI HOME, AND WHY YOU MIGHT NOT EVEN KNOW YOU'RE ADDICTED. ALSO TONIGHT, AN INTERNATIONAL AIRLINE HAS ANNOUNCED THEY'LL BE CHARGING OVERWEIGHT PASSENGERS EXTRA TO GET ON THEIR PLANES. I THINK IT'S ABSOLUTELY RIDICULOUS. WHY? BECAUSE I DON'T THINK PEOPLE SHOULD BE DISCRIMINATED AGAINST BECAUSE OF THEIR WEIGHT. SO, IS THE RULE AN OUTRAGE OR JUST COMMON SENSE? IT'S WEDNESDAY NIGHT. WELCOME TO SEVEN SHARP. AFTER ALL THE SECRECY, TESTING AND TENS OF MILLIONS OF DOLLARS, TEAM NZ'S ABOUT TO HEAD OFF TO TRY AND LIFT THE OLDEST TROPHY IN SPORT, THE AMERICA'S CUP. ALI'S AT THE TEAM NZ BASE AS THEY PACK UP FOR THE LAST TIME. ALI WHAT'S GOING ON? The boat has just come in. They are about to put on a big crane. One thing comes out of the water, that is the last time that will see Auckland harbour in a while. Louis Vuitton Cup, then hopefully the America's Cup. This may be the last time we get the opportunity to do that. Bosses have said it is just getting too expensive to compete. The campaign costs up to $100 million. I'll chat to Grant Dalton shortly. DRUGS,... ALCOHOL,... AND IF YOU'RE AN IMAGINATIVE CELEBRITY, SEX. THREE ADDICTIONS WE ALL HEAR PLENTY ABOUT, BUT ANOTHER ADDICTION'S CONTENTIOUS. SOME SAY IT'S NOT AN ADDICTION AT ALL. A FIVE-YEAR STUDY'S UNDERWAY IN CHRISTCHURCH, BUT THE ADDICTS THEY'RE STUDYING AREN'T SMOKING, DRINKING OR ACTING LIKE TIGER WOODS AT AN OUT-OF-TOWN HOTEL. IN FACT, IF YOU WERE UNKIND, YOU MIGHT SAY THEY'RE NOT ADDICTED, JUST GREEDY. GILL HIGGINS EXPLAINS. IT FEELS LIKE EVERY CELL IN MY BODY IS OBSESSED. IN THE SCIENTIFIC FIELD, THIS IS A RELATIVELY NEW AREA OF RESEARCH. IT FEELS SHAMEFUL AND EMBARASSING. THE ESSENTIAL THING THAT WE NEED TO SURVIVE CAN ACTUALLY BE SOMETHING THAT WE CAN BE ADDICTED TO. IT FEELS SCARY TO KNOW THE CONSEQUENCES OF OBESITY AND YET NOT BE ABLE TO CONTROL MY OVEREATING. OVEREATING USED TO BE... OVEREATING. NOW SOME CALL IT ADDICTION. TRUE OR FALSE, WHAT'S CERTAIN IS IT'S NOW THE SUBJECT OF INTENSE SCIENTIFIC RESEARCH. THERE'S EVEN A FOOD ADDICTION INSTITUTE IN THE STATES. BUT NZ IS JOINING THE PARTY. FIVE YEARS AGO, WE WEREN'T CONVINCED. BUT NOW? WE ARE. WE ARE CONVINCED, AND, LIKE I SAY, PART OF THAT IS FROM LISTENING TO OUR PARTICIPANTS AND OUR RESEARCH. THEY HAVE THIS RELATIONSHIP WITH FOOD WHERE THEY CAN BE TORTURED BY FOOD AND AT THE SAME TIME TOTALLY IN LOVE WITH THEIR FOOD. RATS TOO. IN A STUDY THEY WERE OFFERED THE LIKES OF BACON AND CHEESECAKE FOR JUST ONE HOUR A DAY. THEY LOVED IT. THEY SNUBBED THE 24-HOUR HEALTHIER OPTIONS. EVEN THE THREAT OF ELECTRIC SHOCKS DIDN'T STOP THEM. BUT ANIMAL STUDIES CAN ONLY TELL US SO MUCH. SO FROM RATS... TO MALL RATS. JUST KIDDING. AND YET, LOOK AT THIS. YOU HAVE TO ASK YOURSELF ` WHY DO WE CONSTANTLY SPEND GOOD MONEY ON FOODS WE KNOW AREN'T THAT HEALTHY? THERE ARE THE SAME PATHWAYS, THE SAME KIND OF THINGS THAT HAPPEN IN YOUR BRAIN WHEN OTHER DRUGS ARE INTRODUCED ` THE SAME WHEN PEOPLE ARE OVEREATING. SO SUGAR, SALT, COCAINE ` THEY'RE JUST AS BAD AS EACH OTHER? YEAH. THINGS LIKE THESE CHIPS. FIZZY DRINKS ` SO MUCH SUGAR IN FIZZY DRINKS. THIS CHICKEN IS POTENTIALLY A VERY HEALTHY, NUTRITIOUS FOOD, BUT WHEN IT'S COOKED IN HUGE AMOUNTS OF FAT, THAT'S SOME OF THE INGREDIENTS THAT TEND TO MAKE IT MORE ADDICTIVE. NOT ALL OBESE PEOPLE ARE THOUGHT TO BE ADDICTS. BUT SCIENTISTS HAVE SCANNED THE BRAINS OF THOSE SHOWING SIGNS OF ADDICTION AND FOUND THAT MANY LACK RECEPTORS LINKED WITH REWARD, MEANING THEY KEEP EATING LONG AFTER THE JOY IS GONE. YOU CAN'T JUST TELL THOSE PEOPLE TO EAT LESS AND EXERCISE MORE. WHAT WE NEED TO UNDERSTAND IS THAT THERE'S SOMETHING DRIVING THEIR WEIGHT. IT FEELS LIKE MY THOUGHTS AND IMPULSES SABOTAGE MY ATTEMPTS TO` WELL, CONTROL MY EATING AND USE FOOD IN A REASONABLE WAY. THE WORDS WE'RE USING ARE THOSE OF A SELF-CONFESSED ADDICT, BUT ONE WHO FEELS TOO ASHAMED TO BE SEEN OR EVEN HEARD. WHY? BECAUSE NOT EVERYONE SWALLOWS THE IDEA THAT STUFFING YOURSELF IS AN ADDICTION. IT'S POTENTIALLY LOOKING AT OVERWEIGHT AND OBESITY IN SOME PEOPLE AS A DISORDER OR ILLNESS. I THINK IT WILL HELP PEOPLE WITH OBESITY TO BE LESS STIGMATISED, TO BE LESS JUDGED AND TO BE BETTER SUPPORTED. AND SO THE CHRISTCHURCH STUDY OF 25 PEOPLE ` MAKE THAT LARGE PEOPLE. OUR STUDY IS VERY EXPERIMENTAL ` REWIRING THE BRAIN, CHANGING YOUR RELATIONSHIP WITH FOOD IN A WAY THAT ENABLES YOU TO CONTROL YOUR FOOD INTAKE. OPRAH HAS SHOWN US HOW QUICK FIXES AREN'T LASTING. SO HAS KIRSTIE ALLEY. THE CHRISTCHURCH APPROACH OF IDENTIFYING PROBLEM FOODS AND WORKING OUT WAYS TO REPLACE THEM WILL HOPEFULLY BE MORE SUCCESSFUL. THE ONE THING WE'RE REALLY CONVINCED OF IN OUR STUDY IS THAT CHANGE TAKES TIME. RIGHT NOW, MORBIDLY OBESE PEOPLE CAN GET THEIR STOMACH STAPLED. BUT AS FAR AS HELP GOES, THAT'S GENERALLY ABOUT IT. WE DON'T HAVE GOVERNMENT-FUNDED OBESITY PROGRAMMES OUTSIDE WHAT IS HAPPENING FOR BARIATRIC SURGERY AT THE MOMENT. SO IT IS VERY DIFFICULT FOR PEOPLE WITH OBESITY TO GET PUBLICALLY FUNDED HELP, BUT I REALLY THINK THEY SHOULD. IT FEELS LIKE A SITUATION THAT I'M TRAPPED IN, AND IT TERRIFIES ME THAT I HAVE MODELLED THIS BEHAVIOUR TO MY DAUGHTER. Not wanting to be Mr judgey trousers, but with booze and drugs, you can easily go, 'ooh, this is moreish'. But with food there is nothing impairing your decision-making ability. If you go cold turkey with food, you actually eat cold turkey. It looks like either food addiction tonight in this cardigan. We have a list coming up later of the seven most addictive foods in your kitchen. Guess what they are. AFTER THE BREAK ` THE AIRLINE GIVING A WHOLE NEW MEANING TO WAIT LISTS. WELCOME BACK. BEFORE THE BREAK, WE ASKED IF YOU KNEW WHAT THE MOST ADDICTIVE FOODS IN YOUR PANTRY ARE. WE'LL SHOW YOU VERY SHORTLY. BUT FIRST LET'S CROSS LIVE TO ALI, WHO'S DOWN AT THE AUCKLAND VIADUCT WITH TEAM NZ. This boat is coming out of the water at any second. We will bring that drama to you. Here's Ray Davies, tactician on the boat. You have just had a day sailing. And the technical director for team NZ. What happened last time you took the boat out? We were attempting to put it in. We had a nasty little squall come through. We lost control of it. A certain amount of damage. It'll all be go by the time we get to San Francisco. Not too bad? What is about to happen now? We are all hooked up. Everyone has hard hats on. 35 people involved in this. The whole boat will be lifted on top. We are to keep the boat perfectly lined up if there is any breeze. The wing is lifted off the top of the boat, slowly packed away and put to bed. You then shrink-wrapped the boat and put it on a container ship? Yes, we do. This is the first step in a breakdown and disassembly process. They'll take two weeks to get it on the ship. 16 containers worth of equipment to move up to San Francisco. We take these tents down where we work and reassemble them before we can put the boat back together. A lot of logistics for the shore crew. Ray, you are the model of a modern sailor. Can you talk us through what you're wearing? Touch shoes. A wetsuit. A lightweight kid. I have the computer here to provide real-time darter of what is happening out there. The boat is on the move right now. You're wearing a helmet. It is quite dangerous on the boat. We are now required to wear headgear. You look like a Navy Seal. What's this? Oxygen, just in case we flipped upside down and you end up underneath the trampoline, stuck 2 m underwater. Your rig to the boat. So this gives you time to...? Literally 2 min of air to gather yourself and find the way out. One last thing to ask you. When you realised you might go into the drink at some point ` Oracle's incident ` what did you do training wise? This really hit home that is the reality. It is a long way down. We've been into the swimming pool along there. We were held under by a rope around our ankles. We had to cut ourselves free. We're going through that drill. If you go through that in real life, that training gives us the chance of surviving. Things are joining us this evening. As we can see, the boat is almost on the deck. Now they take that wing off. Into the shed for checks and unpacking. Hopefully we can bring that to you in a minute and speak to Grant Dalton. Looking at that,it is the formula one of yachts. It has as much relevance to a normal yacht as a Formula One car has to your car. It is an incredible machine. SO LET'S GET BACK TO OUR ADDICTIVE FOOD STORY. YOU'VE BEEN SENDING IN THE FOODS YOU'RE OBSESSED WITH. Lots of guesses. People guessing the most addictive foods bread, pistachios, chocolate, Indian food. Well, we're bringing out the seven most addictive. Not the first time, this job feels like working at a bad restaurant. Hot chips, pies, cold chips, Afghans, muesli bars. Will anyone at home be surprised by this? The one surprising thing is muesli bars. Apparently loaded with sugar. University of Otago provided us with this information. This food is non-essential, energy-deficient. AND TUNE IN TOMORROW. WE'LL HAVE A REMARKABLE STORY ABOUT ONE MAN'S FOOD ADDICTION AND HOW HE MANAGED TO BEAT IT, LOSING MORE THAN HALF HIS WEIGHT. STICKING WITH THE THEME OF WEIGHT, WOULD YOU BE WILLING TO PAY FOR AN AIRFARE BASED ON HOW HEAVY YOU ARE? DO YOU THINK THAT'S FAIR? JEHAN CASINADER GRABBED A SET OF SCALES AND HEADED TO THE AIRPORT TO FIND OUT. UPBEAT MUSIC HOW MUCH DO YOU WEIGH? HUNDRED AND... WHAT WAS IT? 118. 118? THINK IT'LL BE ABOUT 75KG. I'M ACTUALLY 64 ON THAT. DO YOU KNOW THAT SAMOAN AIRLINES IS THINKING ABOUT CHARGING PEOPLE BASED ON HOW MUCH THEY WEIGH? I HAD HEARD. SOUNDS PRETTY RIDICULOUS. RIDICULOUS. ABSOLUTELY RIDICULOUS. WHY? BECAUSE I DON'T THINK PEOPLE SHOULD BE DISCRIMINATED AGAINST BECAUSE OF THEIR WEIGHT. HOW MUCH DO YOU WEIGH? 80. SO YOU'RE GONNA HAVE TO PAY MORE? YEAH, WAY MORE. WHAT ABOUT WHEN REALLY BIG PEOPLE SIT NEXT TO YOU ON THE PLANE? IS THAT UNCOMFORTABLE? YES. IT'S A BIT SAD WHEN YOU GET A PERSON WHO'S BEHIND YOU WHO'S GROSSLY OVERWEIGHT. BUT SOME PEOPLE CAN'T HELP IT. THEY HAVE GOT A HEALTH PROBLEM. IT'S JUST NOT FAIR. YES, YOU CAN SEE THE LOGIC, BUT I THINK IT WOULD BE VERY EMBARRASSING. BY THE LOOKS OF SOME OF THE PEOPLE THAT I SAW AROUND HERE TODAY, I THINK... I SAW AN AWFUL LOT OF LARGE PEOPLE. I THOUGHT, 'WELL, I WOULDN'T LIKE TO SIT NEXT TO THEM, I DON'T THINK.' DOESN'T REALLY MAKE MUCH DIFFERENCE HOW MUCH YOU WEIGH. PEOPLE SHOULD BE ALLOWED TO PAY FOR THE SEAT. THAT'S... I THINK THAT'S THE BASIC REQUIREMENT. YOU'D HAVE A VERY CHEAP FLIGHT. MAYBE THERE'S AN ELEMENT OF DISCRIMINATION. WEIGH OR NAY ` THAT'S THE QUESTION. JEHAN'S BACK AT THE AIRPORT NOW. JEHAN? I've spent most of the day at the airport. It is fitting in nicely with my part-time job as a baggage handler. TV NZ does not pay well. I have found one of the Laughing Samoans. Are Samoans laughing? I had a bit of a chuckle, because I thought was an April Fools' joke. Bit sad, you know. When was the last time you jumped on the scales? A while. When I was 5. Hop on the scales. It says you're 20kg. About right. That makes it seem that has gone all the way around and then it was gone around again. Your family are going on a trip with you. After weighing myself at check-in, I realised the price... It's the same as it would been if it was just me, so the family has gone home. I'm going alone. I have to courier my stuff to Samoa. You are paying more, but you're also getting a bit more space That's fair. A bit of extra space. I weigh only 56kg. Cheap flights. Fantastic, guys! You could have got in an under 12 rugby team. 56?! That's pretty light. It is about how much fuel people are going to use. We accept it for excess baggage, and it is a valid point. The heavier the wait, the more fuel burns to carry it. We accept it for baggage, but not with people. One comment from Facebook if Kim Dotcom gets prosecuted, it'll cost more to send him home than jail him. Another viewer said it's totally unfair. If you're tall, you have to pay extra. The All Blacks are officially obese. They're not fat, but they weigh a lot. Another viewer said they spill over their seat and they usually smell as well. AFTER THE BREAK ` ALI'S BESIDE A BOAT WHERE YOU HAVE TO BE BIG TO GET ON BOARD. SHE ASKS GRANT DALTON WHAT OUR CHANCES ARE OF WINNING THE AMERICA'S CUP, NEXT. LET'S GO BACK TO ALI NOW, WHO'S WITH TEAM NZ AS THEY PACK UP THEIR BOAT FOR THE AMERICA'S CUP IN SAN FRANCISCO. A lovely sight in the gathering dusk. Remember how passionate we were in the late 90s about the America's Cup? The red socks. Grant Dalton ` the good old days, eh? Why have you said that this is probably the last time we will do this? It'll be out of our reach financially. The public has probably had enough, especially if we don't win. A third of your money has come from the government. Do you feel some accountability? We feel an obligation to win. But whether we had government money or just sponsor money, we would think the same. Steve Hansen was here today talking about 2007 and 2011 World Cups. We feel the same. We were very close in 2007. This is it. How fast is the boat? It's very fast, but I don't know if it's faster than the other guys. We have been up at 80 K's. When will you know whether it's faster than the others? Dean said it would be your first day in San Francisco bay. We have a gauge on Prada. We've trained with them. In the end, ultimately, it's Oracle. They'll be really strong. There is a lot of skulduggery and spying the goes on. Oracle have been watching you. You've been watching them in San Fran. What do you learn from that? Heaps, and some of that we incorporate in our own boat. We do know that they are fast and getting faster. They have had some issues and mishaps, but they have got back together and getting fast. They have resources and talent. Thank you, Grant. The way to get Kiwis influenced again is to win it and bring it home. Best of luck. Go, Team NZ. THAT'S ALL FOR SEVEN SHARP. SEE YOU TOMORROW NIGHT. CAPTIONS BY RICHARD EDMUNDS AND HUGO SNELL.
