[EX Q]: (CNN) -- I've written quite a bit about medical myths, so I'm always a bit skeptical about medical "knowledge." But one thing I, and I'm sure many of you, think we understand is obesity. After all, weight issues crop up in media constantly. Just last night, Gov. Chris Christie was joking about donuts and his weight on The Late Show with David Letterman, and the First Lady's weight is once again a subject of discussion in the Washington Post--even though by any objective standard she's in great shape. We know how people gain weight, and we think we know how to lose it. Except a study in this week's New England Journal of Medicine shows us that's just not right. Pretty much everything we "know" about obesity and weight loss is wrong. Let's start with some things that are true. More than a third of Americans are obese. Many more are overweight. The Centers for Disease Control and Prevention estimates that obesity-related medical costs were almost $150 billion in 2008, and the cost in health related expensed for an average person who was obese was more than $1,400. This doesn't count the physical, mental or quality-of-life toll that obesity can levy on a person. Few of us dispute that we need to do something about this problem. There are plenty of experts (present company included) who will tell you what needs to be done. The sad truth, though, is that lots of that advice (even mine) turns out to be mistaken. I know I've told people that making small, sustained lifestyle changes is the best way to lose weight over time. But it turns out that making such changes, say by deciding to walk a mile every day for five years, results in far less weight loss than you'd expect. Coca-Cola weighs in on obesity fight . I've lectured people about the importance of physical education in schools, and I've seen countless reports declaring that the decrease in PE nationwide is one of the reasons that more children are obese or overweight today. It turns out that studies don't show that's the case. My family loves watching "The Biggest Loser." But I've found myself telling my kids again and again that what's shown on TV isn't the best way to lose weight. I tell them that slow and steady works better in the long-run than rapid weight loss. I also tell them that setting unrealistic weight goals can actually sabotage your efforts. So imagine my shock to discover that what evidence exists in this new study hints towards ambitious goals being a good thing, and that quicker weight loss isn't less likely to be kept off in the long-term. People will say eating breakfast is a good idea when you're trying to lose weight, because it will keep you from binging later. But studies show that there's no protective effect from eating breakfast at all. People will say that eating more fruits and vegetables is a great way to lose weight. But studies show that, on their own, eating more of them without making other behavioral changes doesn't result in any weight loss. There's no magic to fruits and vegetables. Eatocracy: Chefs with Issues: Farm-to-table should still be on the table . People will say that snacking in between meals can lead to weight gain. But studies don't show that to be the case either. In general, people compensate for snacking throughout the rest of the day. In other words, it's not necessarily bad to snack outside of usual meal times. It's all enough to cause one to despair. But just because so much of what we believe is wrong doesn't mean we still can't do something about the issue. Studies do show that you can absolutely overcome genetic and familial factors to lose weight. They show that significant physical activity can help with weight loss, and that it has the added bonus of making you healthier in general. Reducing your caloric intake works overall, especially if it's done in a way to change your overall eating habits. Getting the whole family involved is important. And finally, for some, bariatric surgery can result in life-changing outcomes. Over the past five years, my wife and I have lost quite a bit of weight. I'm down somewhere between 15% to 20% of my high of more than 200 pounds. My wife lost even more, although I'm not going to give you any numbers (I like being married). Now that I look back, if I'm going to be honest about it, I did it in bursts over a few months here and there, each time gaining back less than I had lost. 7 weight loss myths (sort of) debunked . Each time, I had ambitious goals of 15 pounds or more in two to three months, and each time I really restricted my caloric intake. But I've kept the weight off by radically changing my overall eating habits. My breakfast consists of just coffee, I eat very light lunches, such as salads, and dinner is usually a healthy home-cooked meal with the family. My wife cooks way more than she used to and is obsessed with finding ways to make meals healthier. I avoid fried foods almost entirely, and I can't remember the last time I ate in a fast food restaurant. I also get to the gym two to three times each week. I don't tell you this because I think this is what you should do, or because I think it's the key to getting thinner. I tell you this because more and more, I think that the journey to sustained weight loss is a very personal and individual path. Perhaps our problem is we're trying to find a one-size-fits-all solution. I'm not sure that exists. Lastly, what was left out of this new scientific paper was prevention. The single best way to fight obesity is to avoid it in the first place. That has to start when kids are young, and it's a lifelong journey. But one thing I doubt will ever be proved false is that it's much easier not to gain the weight in the first place than to take it off later.

[EX Q]: PARIS, France (CNN) -- Three French journalists charged in an alleged plot to kidnap African children for adoption in Europe arrived in Paris on Sunday, hours after French President Nicolas Sarkozy held emergency talks in Chad. But 14 other people remained in custody in the African nation, some facing serious charges that could send them to jail for up to 20 years. The journalists were among seven Europeans a Chadian judge released Sunday, including a Spanish flight crew, whom Sarkozy dropped off in a brief stop in Madrid on his way back from Chad. All were arrested last week after workers from Zoe's Ark -- a French-based charity group -- were accused of trying to fly 103 children out of Chad in a kidnapping and adoption operation.  Watch a report on how the events unfolded » . Some of the children may never return to their families because it is too difficult to determine their backgrounds, Red Cross spokeswoman Inah Kaloga told CNN on Friday. Those who remain under arrest in Chad are six members of the French charity, four Chadians and four remaining members of the flight crew. Some face kidnapping and fraud charges. Zoe's Ark leader Eric Breteau testified Saturday to a court in the Chadian capital that the three journalists and the flight crew of seven Spaniards and a Belgian were not involved in the alleged plot, court witnesses told CNN. At least some of the flight crew are scheduled to testify before a judge on Monday. The three journalists initially had been charged with complicity in the alleged kidnapping attempt. It's not clear if the charges against them have been dropped.  Watch the freed Europeans leave Chad » . In a joint news conference with Spanish Prime Minister Jose Luis Rodriguez Zapatero on Sunday at Madrid's Torrejon Air Force Base, Sarkozy expressed satisfaction that some of those detained had been released. At the same time, however, he told reporters, "We should respect the sovereignty of Chad." Zapatero thanked Sarkozy for dropping the four Spanish flight crew members off in their home country, and thanked Chadian President Idriss Deby for allowing them to return. After his emergency talks in Chad, Sarkozy stressed the scandal would not affect the strong relations between the two countries or affect the planned deployment of a European force to protect refugees from Sudan's Darfur region who have fled to Chad and the neighboring Central African Republic. Sarkozy also said he hoped the six remaining French nationals -- all from Zoe's Ark -- would face trial in France. The charity says that the children were orphans from the Darfur region -- where the United Nations estimates 200,000 people have been killed in four years of conflict -- and that the group was taking them to host families in France. But after preliminary interviews with the children, aid agencies said Thursday it appeared most of them probably are not orphans and not from Sudan, but instead come from villages on the Chadian side of the border with Sudan. The children are staying in an Abeche orphanage while aid agencies and government officials try to find out where they came from -- a challenge hindered by the number of children, their youth, and the volatile situation in the region. A father of three of the children allegedly kidnapped told a French newspaper he put his children into the charity's care after he was told they would be educated at a school under construction in a nearby town. The Chadian man, who gave his name as Arbab, told Le Parisien on Sunday that workers from Zoe's Ark had visited his village three times. "They never said they would take away our children," he told the newspaper. E-mail to a friend . CNN's Nic Robertson and Al Goodman contributed to this report.

[EX Q]: (CNN) -- You've been thinking about it for weeks. Mounds of turkey piled high with buttery mashed potatoes, dripping with gravy. Green bean casserole and pumpkin pie. Or sweet potato casserole and pecan pie. Cranberries. Collard greens. Stuffing. Every year, we spend hours making the traditional Thanksgiving favorites just like our mom used to do, like her mom did before that. "When you do something repeatedly over the years, it builds up a kind of power," nutritional psychologist Marc David says. "It creates its own momentum. To make the same dish year after year, decade after decade, there's something in that that connects us to the past." Nostalgia comes from the Greek word for homecoming (nostos) and pain (algos). But experts say feeling nostalgic is actually good for your mental health. Anything can bring on that special moment -- music, smells, photos. We play the same songs, cook the same recipes, take the same family photo in the same spot next to the same fireplace because we're human, David says. Our biological functions are based on repetitive rhythms. Our brains are hardwired to relax when surrounded by the familiar. "Emotional eating has gotten a bad name," David says. "We're emotional people. We are emotional beings. We're built for pleasure." Nostalgic products fill a need to belong and feel socially connected, according to an Arizona State University study published in the Journal of Consumer Research last year. That's why this time of year, TV and radio ads are filled with smiling families sitting around a large table in holiday sweaters, passing the dinner rolls. Even if you're far away from home, companies want you to believe that buying those same dinner rolls will fill your heart with holiday joy. Turns out, it works. Dr. Clay Routledge works with other researchers from the University of Southampton's nostalgia project. He recently published an article in the Journal of Personality and Social Psychology titled "The past makes present meaningful." Nostalgia, Routledge found, increases a person's self-esteem. Daily activities like going to class or attending meetings are routine, even boring. When we engage in nostalgia, we tend to think of the things that are really important to us. That makes us feel like our life is meaningful. Taste of Home's sweet potato tart recipe . "What's amazing about autobiographical memory is that bad memories fade faster than positive memories," Routledge says. "One thing that's interesting about nostalgia is that it's not 100% detail accurate -- it's more the highlights." Nostalgia is largely social. Routledge' s studies found that people who are alone or disconnected feel better after engaging in nostalgia. Yet you're probably dreaming right now about your grandfather's deep-fried turkey, not about him, right? "Is it really about the food?" Routledge asks. "Or is the food just sort of a trigger or cue for what the holidays are really all about, which is relationships. We don't eat these foods other times of the year because we've segmented them off as special. They go with this occasion. They go with the relationships." For Taste of Home editor Catherine Cassidy, Thanksgiving means cooking for the ones she loves. She gets satisfaction in putting good food on the table for her family. So many of our best moments from the past, she says, are rooted in our sense of smell. "We call them food memories. When it comes to the holidays we are always trying to recreate the magic and the specialness we experienced when we were children." So indulge in a little Thanksgiving daydream. Long for the oyster stuffing. Sniff the air in anticipation of mom's pumpkin pie. Then on the big day, enjoy your holiday feast, and all the benefits that come from the power of nostalgia.
