Study Proves Having Fat Friends Makes You Fat
Xemu writes "Having fat friends makes you fat, researchers from Harvard Medical School and the University of California says after after examining 12,067 individuals and 38,611 of their relatives and friends. In same-sex friendships, people were 71 per cent more likely to put on weight if a friend of theirs became obese. "It's not that obese or non-obese people simply find other similar people to hang out with. Rather, there is a direct, causal relationship," says Harvard professor Nicholas Christakis."
I'm suspicious of this fat-friends-make-you-fat story. Heard 'experts' on radio this morning repeating this story, using words like 'infectious', 'contagious'. Smacks of Sensationalist Journalism, and Susy Public will go away thinking she'll get fat if she sits next to a fat person.

This on the other hand is a much better story:

It's an interview with Dr Robert Lustig, Professor of Pediatric Endocrinology at the University of California, San Francisco. He says, yes, we're getting fat, but the question is why our bodies don't enact a defense against this. One of the culprits: Fructose (Corn Syrup) which food and drink manufacturers have been putting in everything. Your body has real problems regulating this. Fructose with Fibre is ok (an Orange), but without Fibre it's very bad (Orange Juice). Apart from the vitamins, you might as well be drinking pop. Very interesting link: transcript and MP3.
High fructose corn syrup is definetly part of the problem. But of course, so are portions. "Do you want to make it a mega-lard-ass size for 15 cents more?" A portion of McDonalds fries (regular size) was 230 kCals in the 60s, now its over 400. A chipolte buritto is about 2/3s of the energy a health 20-40 year-old male needs in a day (granted he is the typical office worker who gets 20-30 minutes of excersize 4 times per week).
EVERYWHERE foods potions have gotten larger. Few people realize that A.) It takes 10-15 minutes to feel full. B.) Thirst is often mistaken for hunger C.) What tastes awesome (like McDonalds, candy, steak, etc) isn't an acceptable meal choice. Eat a pack of star-bursts over 2-3 days, not 10 minutes.
Basically, people are either too ignorant, apathetic, or lazy to make good nutrition choices. You really shouldn't even give little kids that much juice, becauses its nutritional content (high simple carbs) is similar to soda-pop.
BTW, all this came from the M.S. nutrition teacher I had last semester.
It's just an easy way to get a general assessment. Body fat percentage, resting heart rate, heart rate during exercise, etc., are much better metrics of one's overall fitness and health.
I could not justify my existence if I were a turkey farmer. Would I terminate myself? Undoubtably, yes.
Being fat is a choice. You choose to start the day with bacon and eggs, you choose to drink soda and other high-calorie beverages, you choose to stuff those cheeseburgers into your fat face. You choose not to get up off your ass and get some exercise.
I didn't really "choose" to be fat. I did choose to take medicine whose side effect was major weight gain but the alternative was death, and I'd rather get through the issue and work off the weight later than be worm food. After gaining 110 lbs, I've seen exactly how fat people live life and the work required to get that weight back off.
As a fat person, you can still vote, still have a job, still do generally "everything" you expect. Except be comfortable in airplanes, or ride some of the rollercoasters at the amusement park. Oh, and be listened to as attentively as the thin person next to you. Or be taken as seriously at a job interview as the next thin person. It's subtle but real, and my thin friends don't see it at all. In that way it is similar to being a middle-class black person at a white-collar job.
(Of course the "oppression" isn't nearly as bad as actual black middle class experience these days. But it mirrors the lighter end of it, and for many middle-class white people it's the closest they'll come to it. See Ellis Cose's excellent book "The Rage of a Privileged Class: Why Do Prosperous Blacks Still Have the Blues?" for good discussion covering the entire spectrum of black oppression including the "not being taken seriously" part.)
As for losing weight, once your body has gained a huge amount of weight and kept it on for more than a few months, losing the weight becomes a real challenge. Dieting means not eating with friends and family anymore which here in America means instant social isolation. No more potlucks at church, no more barbecues, and no more food at parties. Your life is literally: work, exercise, count calories, and find individually fulfilling things to do in the 2 remaining evening hours of the day while your friends are out having a life.
Exercise also requires a lot more thinking than most people are used to. For instance, if you weigh more than 300 pounds you simply cannot run or use a stairmaster machine because you risk permanent knee injury, and you cannot really "walk" on the treadmill either as that doesn't burn enough calories to benefit you. However, you can use an elliptical trainer, stationary bike, and punching bag to kick the heart rate up. A personal heart rate monitor only costs $70 and goes a long way to ensuring the workout intensity remains high.
Losing serious amounts of weight requires the kind of dedication we normally associate with martial arts. A fat person who is seriously losing weight (and I've lost 30 of my 110 extra pounds so far) needs to know as much about fitness as an amateur bodybuilder. It requires money to buy healthier food, gym membership and/or personal training, and equipment, and it also requires enough free time to actually use those fitness resources and shop for food correctly. Finally, it requires a lot of not fucking caring about the world because even your closest family might not notice the first six months and 30 pounds and you'd better stick with it despite all the negative reinforcement around you. The world will always think I suck (because I "chose" to eat crap) until that magic moment I stop looking fat and people start seeing me as a real person again.
Having been in the fat shoes, I have a lot more sympathy for people who have little free time and money and aren't quite introverted enough to handle the social isolation.
Comparing yourselves to minorities who have actually been oppressed is sickening.
Now that's rich: here on Slashdot, the enclave of middle-class white privilege, we're finally told that minorities really are oppressed!
The study is talking about probabilistic causation.
= 300 about indeterminism= 228 about causal analysis
Read on wikipedia about regression, gaussian distribution (central limit theorem) and explained variance and it should become clearer.
A good book about causal modelling is: http://bayes.cs.ucla.edu/BOOK-2K/
It's not like we experience determinism in the real world. here are two of the many papers patrick suppes wrote on this topic:
