It didn't stop him from getting elected governor. Believe it or not--sometimes Americans do listen to someone's ideas."I am not Jon Corzine" is not an "idea".
"The implications were clear. There is a reason that fat people cannot stay thin after they diet and that thin people cannot stay fat when they force themselves to gain weight. The body's metabolism speeds up or slows down to keep weight within a narrow range. Gain weight and the metabolism can as much as double; lose weight and it can slow to half its original speed."posted by muddgirl at 12:32 PM on October 3, 2011 [14 favorites]
"Maintenance of a reduced or elevated body weight is associated with compensatory changes in energy expenditure, which oppose the maintenance of a body weight that is different from the usual weight."
These studies show that one third to two thirds of dieters regain more weight than they lost on their diets, and these studies likely underestimate the extent to which dieting is counterproductive because of several methodological problems, all of which bias the studies toward showing successful weight loss maintenance. In addition, the studies do not provide consistent evidence that dieting results in significant health improvements, regardless of weight change. In sum, there is little support for the notion that
diets lead to lasting weight loss or health benefits.
In two papers published this week in the Archives of Pediatrics and Adolescent Medicine, scientists found that preschool-age children who had trouble with self-control and the ability to delay gratification gained more weight by the time they were preteens than those who were better at regulating their behavior.posted by pracowity at 1:09 PM on October 3, 2011
"I've tried every other crazy method in the world, but you just lose weight and you gain it back," he told Imus.Not surprising, considering study after study shows that diets don't work for the vast majority of people. Until science figures out a method to beat the body's set point system and metabolic damage occurring over many years, I don't think it's wise to tell people that they can get thin by eating better. That said, Christie appears to still be on the dieting rollercoaster and is STILL trying, despite failing several times already.
So Hirsch and his colleagues, including Rudolph Leibel, who is now at Columbia University, repeated the experiment and repeated it again. Every time the result was the same. The weight, so painstakingly lost, came right back. But since this was a research study, the investigators were also measuring metabolic changes, psychiatric conditions, body temperature and pulse. And that led them to a surprising conclusion: fat people who lost large amounts of weight might look like someone who was never fat, but they were very different. In fact, by every metabolic measurement, they seemed like people who were starving.Even while weight loss was being sustained, it had a host of side effects, including ratcheting down metabolic rate to oppose the weight loss -- a protective effect that you would see in a starving person of normal weight. And to top it off, as soon as the subjects were released from the study they quickly rebounded to their previous weight. I don't know, maybe this counts as "working" to you, but I sure wouldn't call it that.
Before the diet began, the fat subjects' metabolism was normal - the number of calories burned per square meter of body surface was no different from that of people who had never been fat. But when they lost weight, they were burning as much as 24 percent fewer calories per square meter of their surface area than the calories consumed by those who were naturally thin.
Is Christie robust? Then fine.
T. Roosevelt had already proven himself robust in the Rough Riders. He was the original tough guy before the bullet.
Christie's clinical obesity certainly raises the probability that he will be incapacitated/die in office.
His weight is actually a concern. The presidency is a very stressful job and I can't stand the thought of him keeling over dead...
According to the researchers, it is easy to gain weight unwittingly from a very small imbalance in the number of calories consumed over calories used. Just 10 extra calories a day is all it takes to raise the body weight of the average person by 20 pounds in 30 years, the authors wrote.posted by Forktine at 6:04 AM on October 4, 2011 [2 favorites]
Furthermore, the same increase in calories will result in more pounds gained by a heavier person than by a lean one — and a greater proportion of the weight gained by the heavier person will be body fat. This happens because lean tissue (muscles, bones and organs) uses more calories than the same weight of fat.
In an interview, Dr. Hall said the longstanding assumption that cutting 3,500 calories will produce a one-pound weight loss indefinitely is inaccurate and can produce discouraging results both for dieters and for policy changes like the proposed tax on sugar-sweetened beverages.
If the 3,500-calorie rule applied consistently in real life, it would result in twice the weight loss that the new model predicts, the authors wrote. This helps to explain why even the most diligent dieters often fail to reach weight loss goals that were based on the old rule.
A more realistic result, he said, is that cutting out 250 calories a day — the amount in a small bar of chocolate or half a cup of premium ice cream — would lead to a weight loss of about 25 pounds over three years, with half that loss occurring the first year. ...
Still, obese people would have to cut out more calories to lose weight than it took to gain the extra pounds. Although reaching a weight of 220 pounds may have been caused by consuming, say, 250 calories more than were used each day, losing that weight requires much larger reductions in calorie intake. According to Dr. Hall’s calculations, an extra 220 calories a day are now maintaining the new higher weight.
For the population to return to average body weights of the 1970s, obese individuals, who now represent 14 percent of the population, would have to cut out more than 500 calories a day, the new model shows.
