What happens when the winners of reality show The Biggest Loser go home? Researchers followed a set of contestants for 6 years and came to a disheartening conclusion: losing weight lowers your metabolism (possibly permanently) and increases the hormones that make you hungrier. (SLNYT) [more inside]
A year ago, Des Moines Register columnist Daniel Finney was about to turn 40 and weighed 563 pounds. After he was offered a wheelchair when he became short of breath on a routine reporting assignment, he made up his mind to try to lose weight. When the column he wrote about his decision went viral, he decided to chronicle his efforts in a blog called Making Weight. A year later, 95 pounds lighter, and significantly fitter and healthier, he looks back on the effort in today's paper. Previously [more inside]
In 1972, a British scientist sounded the alarm that sugar—and not fat—was the greatest danger to our health. But his findings were ridiculed and his reputation ruined. How did the world’s top nutrition scientists get it so wrong for so long?
As debate rages about whether to introduce a sugar tax, this is the story of how Mexico defied its own powerful fizzy drinks industry to impose a tax on soda. [more inside]
Reducing consumption of added sugar, even without reducing calories or losing weight, has the power to reverse a cluster of chronic metabolic diseases, including high cholesterol and blood pressure, in children in as little as 10 days, according to a study by researchers at UC San Francisco and Touro University California.

Yoni Freedhoff is an assistant professor of family medicine at the University of Ottawa and the founder of the Bariatric Medical Institute which is a multi-disciplinary, ethical, evidence-based nutrition and weight management centre. Dr. Freedhoff has been referred to as Canada's most outspoken obesity expert and the Canadian Medical Association Journal once dubbed him a Canadian "nutritional watchdog". In other words, he's a respected professional - and he's using that power for good. [more inside]
Medical Fat Shaming Could Have Killed Me Sex educator Rebecca Hiles (Frisky Fairy) details the years of being told to lose weight to deal with her persistent cough before doctors finally diagnosed her with lung cancer. Part I of her cancer story.
The 2015 Dietary Guidelines Advisory Committee (DGAC) report, submitted to the U.S. Department of Health and Human Services and the U.S. Department of Agriculture, makes a historic change: for the first time since 1980, the report no longer recommends the restriction of dietary cholesterol nor of total dietary fat. An article published today in JAMA calls on HHS and USDA to heed the DGAC report. The article goes on to praise the report's new emphasis: reducing consumption of sugar and refined carbohydrates, and increasing consumption of whole foods (even those high in fats).
I'm fat," Daniel P. Finney wrote in an April 12 column in the Des Moines Register. "Scratch that. I'm morbidly obese." Finney, the Register's Metro Voice columnist, was 39 years old and weighed more than 500 pounds. Facing excruciating pain, type II diabetes, and concern that he would soon lose the ability to walk, he decided to make a serious effort to lose weight. He has been chronicling that effort in a blog, Making Weight. [more inside]
Our waistlines aren’t expanding because people aren’t exercising intelligently or vigorously enough. You don’t need a new personal trainer, another Insanity workout video or a more aggressive CrossFit regimen. What you need is the truth, and here it is: Exercise — no matter how many gym memberships you buy or how often you wear your Fitbit — won’t make you lose weight. [more inside]
How Obesity Became a Disease [The Atlantic] And, as a consequence, how weight loss became an industry.
The team gathered samples over the course of a year from sewage treatment plants in 71 different cities in 31 states, chosen for their geographic spread and range of obesity rates. The leanest city sampled was Steamboat Springs, Colorado, with an obesity rate of 13.5 percent, while the heaviest was St. Joseph, Missouri, with a rate of 37.4 percent. ... "If we had a city with a higher percentage of obese people, we would see a higher percentage of the kinds of bacteria associated with obesity,"
Ever wondered what a days worth of calories looks like in fast food form? Well wonder no more!
Here, we show you what roughly 2,000 calories looks like at some large chains. (Depending on age and gender, most adults should eat between 1,600 and 2,400 calories a day.) Researchers have long understood that people are more likely to finish what’s on their plate than to stop eating because they’ve consumed a given amount of food. It’s “the completion compulsion,” a phrase coined in the 1950s by the psychologist Paul S. Siegel.[more inside]
Your body is home to about 100 trillion bacteria and other microbes, collectively known as your microbiome. Naturalists first became aware of our invisible lodgers in the 1600s, but it wasn’t until the past few years that we’ve become really familiar with them. This recent research has given the microbiome a cuddly kind of fame. We’ve come to appreciate how beneficial our microbes are — breaking down our food, fighting off infections and nurturing our immune system. It’s a lovely, invisible garden we should be tending for our own well-being. But in the journal Bioessays, a team of scientists has raised a creepier possibility. Perhaps our menagerie of germs is also influencing our behavior in order to advance its own evolutionary success — giving us cravings for certain foods, for example.[more inside]
“This is not your grandmother’s hunger,” says Janet Poppendieck, a sociologist at the City University of New York. “Today more working people and their families are hungry because wages have declined.”
"... trolling wasn’t the work of just a few bad apples. Instead, there were many, many people who sent us mean messages saying that they simply thought the blog shouldn’t exist." Amanda Levitt of FatBodyPolitics.com writes about the role that trolling, up to and including threats of violence and doxxing, plays in maintaining privilege and furthering oppression.
IF you walk into a farm-supply store today, you’re likely to find a bag of antibiotic powder that claims to boost the growth of poultry and livestock. That’s because decades of agricultural research has shown that antibiotics seem to flip a switch in young animals’ bodies, helping them pack on pounds. Manufacturers brag about the miraculous effects of feeding antibiotics to chicks and nursing calves. Dusty agricultural journals attest to the ways in which the drugs can act like a kind of superfood to produce cheap meat. But what if that meat is us?
Neurobiologist Stephan Guyenet provides two video introductions to his intriguing hypothesis about the cause of obesity: frequently eating highly palatable processed foods (foods with high "reward" effect in the brain) alters the hypothalamus, raising the body's homeostatic set point. [more inside]

Study may bust myth of 'fat and fit' healthy obesity. Being healthy and obese is a myth, researchers say. People who are obese and have normal blood pressure, cholesterol and blood-sugar readings will still be unhealthy and die sooner compared with people who have a normal body weight, according to researchers.

What No One Tells You About Losing Lots of Weight. For at least some newly thin people, there’s a meta-dissatisfaction in feeling that significant weight loss has made life anything other than perfect: Any discomfort you may feel with your body is compounded by a sense of shame at not feeling unmitigated pride at a moment you expected to be triumphant.

Myths, Presumptions, and Facts about Obesity, from the New England Journal of Medicine. Among the myths discussed: Small sustained changes in eating or exercise make a big difference in weight; losing big amounts of weight quickly is less effective long-term than slow and gradual loss; that PE classes help reduce weight; and, tragically, that "a bout of sexual activity burns 100 to 300 kcal for each participant." But take heart! The authors point out that presumptions around the badness of snacking and yo-yo dieting are not supported! (There is also a correction to the original article, because the issue of breakfast remains contentious.)
In 1954, Life magazine published an article entitled "The Plague of Overweight" with a series of photos of a woman named Dorothy Bradley. The story features some now-familiar tropes about fat people ("197-pound Dorothy ... covered up embarrassment by being jolly and gregarious"; "Dorothy envies slim girl's milkshake"). It is also notable as an early appearance of the concept of an obesity "epidemic".
In a remarkable paper Allison et al. (2011) gather data on the weight at mid-life from 12 animal populations covering 8 different species all living in human environments. Dividing the sample into male and female they find that in all 24 cases animal weight has increased over the past several decades.
A layperson-friendly analysis of a seminal (1100+ cites) study on obesity that found no correlation between environment/upbringing and obesity, whilst finding very strong correlation between genetic heritage and obesity. To sum up: adopted children's body weight matches their biological parents, not their adoptive parents.
"The story of American families facing food insecurity is as frustrating as it is heartbreaking, because the truth is as avoidable as it is tragic. Here in the richest country on earth, 50 million of us — one in six Americans — go hungry. More than a third of them are children. And yet Congress can’t pass a Farm Bill because our representatives continue to fight over how many billions to slash from the Supplemental Nutrition Assistance Program, better known as food stamps. The debate is filled with tired clichés about freeloaders undeserving of government help, living large at the expense of honest, hardworking taxpayers." Bill Moyers spends an hour with two of the creators of the documentary "A Place at the Table." [more inside]

The true secret of Easter - but are toys replacing candy (or, more awfully, live animals) as the traditional Easter gift? And is that a bad thing?
Everyone's favourite shit-disturbing pediatric endocrinologist recently became a published author of popular science. He's not doing it for money, and given the upturned noses of some of his brethren, probably not for love, either. The parade of overweight kids passing through his clinic at UCSF's Benioff Children's keeps getting longer, and the man is angry. So angry, he's going to law school to help quarterback the fight against the processed food industry himself. Previously.
291 diseases and injuries + 67 risk factors + 1,160 non-fatal complications = 650 million estimates of how we age, sicken, and die

NYC Mayor Michael Bloomberg has proposed a ban on the sale of large sodas and other sugary drinks at restaurants, movie theaters and street carts. Mr. Bloomberg’s proposal requires the approval of the Board of Health, a step that is considered likely because the members are all appointed by him, and the board’s chairman is the city’s health commissioner, who joined the mayor in supporting the measure on Wednesday.
Consequences, Choices, Children in Crisis, Challenges. HBO’s multi-part research documentary The Weight of the Nation examines obesity in America in four parts, marshaling leading doctors, epidemiologists, economists, researchers, and community leaders to understand and explain the individual costs and public solutions to a multi-faceted social and individual problem. The documentary both explores large picture statistics, while giving voice “to those that often too seek to be invisible: members of the nearly 70 percent of Americans currently diagnosed as overweight or obese.

That the conventional wisdom of 3,500 calories less is what it takes to lose a pound of weight is wrong. The body changes as you lose. Interestingly, we also found that the fatter you get, the easier it is to gain weight. An extra 10 calories a day puts more weight onto an obese person than on a thinner one. [more inside]
Nichelle Gainer (whose Vintage Black Glamour blog was seen previously on MeFi) responds insightfully to a NY Times editorial by author Alice Randall called "Why Black Women Are Fat."
The food desert has been a regular topic here on MetaFilter, posts about which often highlight a particular narrative about the effects of meager food choices for poorer urban communities, negatively affecting health and choice among low income people. Though not always. Some new studies indicate the situation in the US might be more like the latter, not quite as dire as is usually asserted. [more inside]
A new study conducted by Dr. Eric Braverman, president of the nonprofit Path Foundation in New York City, and Dr. Nirav Shah, New York State’s Commissioner of Health suggests that the Body Mass Index significantly underestimates the rate of obesity in America, especially for women. Based on BMI, about one-third of Americans are considered obese, but when other methods of measuring obesity are used, that number may be closer to 60%. [more inside]
The Link Between Adult Obesity and Childhood Trauma (Time magazine article) Felitti wondered if there was something similar barring weight loss in other patients — or causing obesity itself. In the late '80s, he began a systematic study of 286 obese people, and discovered that 50% had been sexually abused as children. That rate is more than 50% higher than the rate normally reported by women, and more than triple the average rate in men....

Stark billboards and television commercials that feature overweight kids are part of a controversial anti-obesity campaign in Atlanta. The goal of the "Stop Sugarcoating It, Georgia" ads is to shock families into recognizing that obesity is a problem.
The Fat Trap (NYT pop review): Overweight individuals in Western nations (and, increasingly, beyond) face interpersonal and institutional stigma for their bodies*. Oftentimes, these stigmas are predicated on the belief that being overweight is a moral failure, that being overweight is usually a result of laziness, decadence, and/or characterlogical poor impulse control. However, an emerging consensus among obesity researchers points toward strong, common physiological and individual genetic factors as causative for heightened BMIs in the modern world and the general failure of dieting to produce BMI outcomes. A recent study in the New England Journal of Medicine (paywalled) adds to this body of evidence, suggesting that chemical messengers held to contribute to altered "efficient" metabolism and increased hunger in the wake of low-calorie dieting are (on average) significantly elevated up to a full year (if not longer) following a substantial drop in weight from dieting.> [more inside]
Obese monkeys lose weight by new drug that kills off fat cells. Adipotide is the newest weapon in the war on obesity. Unlike other weight-loss drugs that try to suppress appetite, boost one's metabolism, or block the absorption of fat, Adipotide blocks the blood supply that feeds fatty tissue. Studies show monkeys lost 11% of their body weight after 4 weeks of treatment.
