This is an animated gif that shows the change i the prevalence of obesity in the US over 18 20 years.
Amazing, and kinda off-putting.

Prevalence of Obesity in the USA | Incredimazing

What are the underlying reasons for this? Probably many, from video game playing/television babysat kids, to the fact that we, as a nation are getting older (baby-boomers anyone?), to the fact that good food is getting more expensive (why fix a nice healthy meal with expensive veggies, when that box of mac and cheese only costs $.50?)
(There’s a chart I saw somewhere with food prices/obesity rate transposed, I’ll see if I can find it and post it later.)
Here it is:

WTF?
There are several reasons for this, not the least of which is farm subsidies, which pay farmers to not grow food. Imagine that.
Check this out: Food Without Thought(pdf) (It’s a pdf–you’ll need a pdf reader like Adobe Acrobat Reader, or Evince, on Linux.)
Looks like 2008 is going to be even worse on food prices. Time to plant a garden, and grow you own damn chickens, I guess.

…it could be in your genes.

Happiness May Be in the Genes

People tend to be hardwired for happiness, and new genetic research may help explain why. Past studies suggest that while 50% of happiness is due to situational factors like health, relationships, and career, the other 50% is due to genes. The new research identified largely inherited personality traits that researchers say are responsible for much of the genetic influence on happiness.

The findings do not mean that people who don’t inherit happiness traits are destined to lead miserable lives, Bates says.
Bates, Weiss, and Luciano are studying whether adopting the traits associated with happiness can make people happy. Early findings suggest it can.
Since setting and achieving goals is a common trait in conscientious people, and conscientiousness is linked to happiness, study participants were asked to set five achievable goals that could be accomplished in a week.

“As soon as people started working toward these goals their happiness scores went up,” Bates says. “When they were no longer working toward a goal their happiness scores dropped.”

“As soon as people started working toward these goals their happiness scores went up,” Bates says. “When they were no longer working toward a goal their happiness scores dropped.”
So while some people are genetically predisposed to being goal-oriented and others are not, the research suggests that it is the behavior that drives happiness, whether or not it comes naturally.
People who stay physically active and socially connected also tend to be happier, so adopting these traits is important for people who are naturally introverted, Bates says.

Situational factors do matter, Bates says, but they don’t tend to affect happiness long term. Studies consistently show that rich people are not much happier than poor people, and even people with severe physical disabilities tend to find happiness over time, he says. “This is what led to the thinking that certain people must have some reserve that allows them to remain at a fairly stable level of happiness despite their situation,” he adds. The research also suggests that happiness is tied to a sense of responsibility and achievement. “The way to pursue happiness is surprisingly virtuous,” Bates concludes. “A sense of humility, working for the things you want, counting your blessings, being sociable, and staying active all play a part.”

So says a report in the New York Times: Midnight Meals – New York Times

“Eating a big meal just before going to bed has been found in studies to elevate triglyceride levels in the blood for a period of time,” Dr. Aronne said. A higher triglyceride level “has been associated with metabolic syndrome and insulin resistance,” both related to weight gain, he said.
Dr. Aronne suggested a theoretical framework for why late meals may stay with you. “If you ate 500 calories during the day but walked around afterward, your muscles would be competing with your fat cells for the calories and could burn them up as energy for physical activity,” he said. “But if you consume it at bedtime, with no physical activity, the body has no choice but to store the calories away as fat.”
