What is commonly believed to be “Fact” about weight loss, including weight-loss and health, has no basis in evidence from Scientific Research.

No matter how many people believe a lie, it will never become the truth.

Repeating an untruth as though it were true, over and over, will never make it true. 

Also, wishing, hoping, or believing that something is true won’t magic away objective facts.

A current event along that line occurred when aides of the new president recently denied the reality of certain specific objective facts even though photographic and other verifiable evidence proved that those facts were True.  Even though the truth was clearly visible, the White House denied it.  One aide even defended their false statements as being an offer of “Alternative Facts”.  After that new political term was used to justify Falsehoods, Lies, and Untruths, it was corrected by a tweet from the Merriam-Webster Dictionary saying: “A fact is a piece of information presented as having objective reality.”

Below is an accurate article showing how the marketing of  “Alternate Facts” has been effectively applied to Weight-Loss isues.


When We Talk About Weight Loss Research
                    
              by Ragen Chastain of Dances with Fat

One of the reasons that I’m no longer interested in attempting weight loss is that my review of the literature informs me that it simply has no basis in evidence as being an effective way to either lose weight or become more healthy (which are two separate things).  When I say that, people often object insisting that there are studies where people have lost weight.

The problem is that any old research where a couple of people lost weight won’t do (go ahead, review the literature.  I think you’ll be shocked to find how often the average participant lost a few pounds, gained back half of it before they stopped tracking, and then the authors declare the study a success.)

The research we would need for weight loss to meet the criteria of an evidence-based medical intervention is twofold.  First, we would need a study where the majority of the participants lost the amount of weight that we are told we need to lose to change our health and maintain that weight loss long term (over 5 years).  If we had those studies – and we don’t –  we would then need some proof that weight loss actually caused health improvements – and this study already brings that into question.

This rules out the National Weight Control Registry because they’ve chosen to study 10,000 people who experienced weight loss while completely ignoring the up to 800,000,000 failed attempts that happened in the same time frame.  Then they just look for things that the 10,000 have in common. So when they say things like “eating breakfast contributes to weight loss” what they actually mean is that they asked the 10,000 people who succeeded what they did, and a majority of them said that they ate breakfast.  Note that they didn’t ask how many of the up to 800,000,000 people who did not lose weight also ate breakfast – that would be important information to have since if a majority of the people who didn’t lose weight also ate breakfast then breakfast may have absolutely nothing to do with it.

Imagine if I got together everyone who had survived a skydiving accident when their parachute didn’t open and started looking for things they have in common.  Even if every single one of them wore a green shirt and had oatmeal for breakfast, I cannot say that wearing a green shirt and eating oatmeal will allow you to survive a skydiving accident, nor can I ethically start Ragen’s School of No Parachute Skydiving “free green shirt and oatmeal with every jump!”  When your entire sample is a statistical anomaly, your research is useless. When all you’re looking for is random coincidence among a select group of outliers, you’d be better off using your research money on lottery tickets.

Other times, people bring up studies where phase 1 was weight loss and phase 2 was maintenance, the study lost between 40% and 70% of participants during or after phase one, and then the researchers continued on as if the remaining people were the complete study group.  Not ok. Why did all of those people quit?  How will their experience be accounted for?

Often the remaining subjects start gaining back the weight they lost so that at the end of phase 2 the average participant has gained back half of their weight with a net loss of less than 10 pounds.  Or they only follow up for a year or two when we know that most people gain their weight back by year 5.

People list study after study and all of them have one or more of the above problems, which I or someone else in the discussion points out.  At that point, the person listing the studies often gets frustrated and says something like “Why don’t you like my studies?” or “You just don’t want to believe.”   If they examined it, I think they’d find that their frustration isn’t with me, it’s with the fact that they’ve been sold a lie and they bought it at full retail price.

I certainly know that frustration, when I did my first literature review of weight loss research I expected to find that all diets worked – I was just looking for the “best” one, the one that had the most solid success.  I was so shocked at what I found that I read through all of the literature again.  I simply couldn’t believe that this thing – weight loss – that had been marketed to me more aggressively than anything else in my life had no basis in evidence. 

I couldn’t believe that doctors had been giving me an intervention which had been shown repeatedly to almost always end in failure, and the majority of time had the exact opposite of the intended result.  When I found out that there weren’t even any studies that showed that weight loss caused changes in health I was just stunned.

It took me a lot of time and a lot of work to accept the truth.  It was hard to find out that I’d been lied to (on purpose and inadvertently), it was hard to find out that the thing that I’d been promised would solve all of my problems was never going to happen. 

In many ways, at least for me, Health at Every Size was about giving up, but that’s what I do when I find out that I’ve been harboring a mistaken belief.  That’s what scientists (well, good scientists) do when their research does not support their hypothesis (however strongly held or widely believed it might be.)  They don’t suspend the rules of research and logic and argue for a belief that they can’t support with evidence.

After’The Biggest Loser,’ Their Bodies Fought to Regain Weight
by Gina Kolata,   - New York Times, May 2, 2016

Danny Cahill stood, slightly dazed, in a blizzard of confetti as the audience screamed and his family ran on stage. He had won Season 8 of NBC’s reality television show “The Biggest Loser,” shedding more weight than anyone ever had on the program — an astonishing 239 pounds in seven months.

When he got on the scale for all to see that evening, Dec. 8, 2009, he weighed just 191 pounds, down from 430. Dressed in a T-shirt and knee-length shorts, he was lean, athletic and as handsome as a model.

“I’ve got my life back,” he declared. “I mean, I feel like a million bucks.”

Mr. Cahill left the show’s stage in Hollywood and flew directly to New York to start a triumphal tour of the talk shows, chatting with Jay Leno, Regis Philbin and Joy Behar. As he heard from fans all over the world, his elation knew no bounds.

But in the years since, more than 100 pounds have crept back onto his 5-foot-11 frame despite his best efforts. In fact, most of that season’s 16 contestants have regained much if not all the weight they lost so arduously. Some are even heavier now.

Yet their experiences, while a bitter personal disappointment, have been a gift to science. A study of Season 8’s contestants has yielded surprising new discoveries about the physiology of obesity that help explain why so many people struggle unsuccessfully to keep off the weight they lose.

Kevin Hall, a scientist at a federal research center who admits to a weakness for reality TV, had the idea to follow the “Biggest Loser” contestants for six years after that victorious night. The project was the first to measure what happened to people over as long as six years after they had lost large amounts of weight with intensive dieting and exercise.



The results, the researchers said, were stunning. They showed just how hard the body fights back against weight loss.

“It is frightening and amazing,” said Dr. Hall, an expert on metabolism at the National Institute of Diabetes and Digestive and Kidney Diseases, which is part of the National Institutes of Health. “I am just blown away.”

It has to do with resting metabolism, which determines how many calories a person burns when at rest. When the show began, the contestants, though hugely overweight, had normal metabolisms for their size, meaning they were burning a normal number of calories for people of their weight. When it ended, their metabolisms had slowed radically and their bodies were not burning enough calories to maintain their thinner sizes.

Researchers knew that just about anyone who deliberately loses weight — even if they start at a normal weight or even underweight — will have a slower metabolism when the diet ends. So they were not surprised to see that “The Biggest Loser” contestants had slow metabolisms when the show ended.

What shocked the researchers was what happened next: As the years went by and the numbers on the scale climbed, the contestants’ metabolisms did not recover. They became even slower, and the pounds kept piling on. It was as if their bodies were intensifying their effort to pull the contestants back to their original weight.

Mr. Cahill was one of the worst off. As he regained more than 100 pounds, his metabolism slowed so much that, just to maintain his current weight of 295 pounds, he now has to eat 800 calories a day less than a typical man his size. Anything more turns to fat.

‘A Basic Biological Reality’

The struggles the contestants went through help explain why it has been so hard to make headway against the nation’s obesity problem, which afflicts more than a third of American adults. Despite spending billions of dollars on weight-loss drugs and dieting programs, even the most motivated are working against their own biology.



Their experience shows that the body will fight back for years. And that, said Dr. Michael Schwartz, an obesity and diabetes researcher who is a professor of medicine at the University of Washington, is “new and important.”

“The key point is that you can be on TV, you can lose enormous amounts of weight, you can go on for six years, but you can’t get away from a basic biological reality,” said Dr. Schwartz, who was not involved in the study. “As long as you are below your initial weight, your body is going to try to get you back.”

The show’s doctor, Robert Huizenga, says he expected the contestants’ metabolic rates to fall just after the show, but was hoping for a smaller drop. He questioned, though, whether the measurements six years later were accurate. But maintaining weight loss is difficult, he said, which is why he tells contestants that they should exercise at least nine hours a week and monitor their diets to keep the weight off.

“Unfortunately, many contestants are unable to find or afford adequate ongoing support with exercise doctors, psychologists, sleep specialists, and trainers — and that’s something we all need to work hard to change,” he said in an email.

The study’s findings, to be published on Monday in the journal Obesity, are part of a scientific push to answer some of the most fundamental questions about obesity. Researchers are figuring out why being fat makes so many people develop diabetes and other medical conditions, and they are searching for new ways to block the poison in fat. They are starting to unravel the reasons bariatric surgery allows most people to lose significant amounts of weight when dieting so often fails. And they are looking afresh at medical care for obese people.

The hope is that this work will eventually lead to new therapies that treat obesity as a chronic disease and can help keep weight under control for life.

Most people who have tried to lose weight know how hard it is to keep the weight off, but many blame themselves when the pounds come back. But what obesity research has consistently shown is that dieters are at the mercy of their own bodies, which muster hormones and an altered metabolic rate to pull them back to their old weights, whether that is hundreds of pounds more or that extra 10 or 15 that many people are trying to keep off.

There is always a weight a person’s body maintains without any effort. And while it is not known why that weight can change over the years — it may be an effect of aging — at any point, there is a weight that is easy to maintain, and that is the weight the body fights to defend. Finding a way to thwart these mechanisms is the goal scientists are striving for. First, though, they are trying to understand them in greater detail.

Dr. David Ludwig, the director of the New Balance Foundation Obesity Prevention Center at Boston Children’s Hospital, who was not involved in the research, said the findings showed the need for new approaches to weight control. He cautioned that the study was limited by its small size and the lack of a control group of obese people who did not lose weight. But, he added, the findings made sense.

“This is a subset of the most successful” dieters, he said. “If they don’t show a return to normal in metabolism, what hope is there for the rest of us?”

Still, he added, “that shouldn’t be interpreted to mean we are doomed to battle our biology or remain fat. It means we need to explore other approaches.”

Slimmer and Hungrier

Some scientists say weight maintenance has to be treated as an issue separate from weight loss. Only when that challenge is solved, they say, can progress truly be made against obesity.

“There is a lot of basic research we still need to do,” said Dr. Margaret Jackson, who is directing a project at Pfizer. Her group is testing a drug that, in animals at least, acts like leptin, a hormone that controls hunger. With weight loss, leptin levels fall and people become hungry. The idea is to trick the brains of people who have lost weight so they do not become ravenous for lack of leptin.

While many of the contestants kept enough weight off to improve their health and became more physically active, the low weights they strived to keep eluded all but one of them: Erinn Egbert, a full-time caregiver for her mother in Versailles, Ky. And she struggles mightily to keep the pounds off because her metabolism burns 552 fewer calories a day than would be expected for someone her size.

“What people don’t understand is that a treat is like a drug,” said Ms. Egbert, who went from 263 pounds to just under 176 on the show, and now weighs between 152 and 157. “Two treats can turn into a binge over a three-day period. That is what I struggle with.”

Rebecca Wright and her husband, Daniel Wright, have gained back a lot of the weight they lost six years ago on Season 8 of “The Biggest Loser”.  They are featured in the VIDEO at the bottom of this Article.

Six years after Season 8 ended, 14 of the 16 contestants went to the N.I.H. last fall for three days of testing. The researchers were concerned that the contestants might try to frantically lose weight before coming in, so they shipped equipment to them that would measure their physical activity and weight before their visit, and had the information sent remotely to the N.I.H.

The contestants received their metabolic results last week. They were shocked, but on further reflection, decided the numbers explained a lot.

“All my friends were drinking beer and not gaining massive amounts of weight,” Mr. Cahill said. “The moment I started drinking beer, there goes another 20 pounds. I said, ‘This is not right. Something is wrong with my body.’”

Sean Algaier, 36, a pastor from Charlotte, N.C., feels cheated. He went from 444 pounds to 289 as a contestant on the show. Now his weight is up to 450 again, and he is burning 458 fewer calories a day than would be expected for a man his size.

“It’s kind of like hearing you have a life sentence,” he said.

Losing a Key Hormone

Slower metabolisms were not the only reason the contestants regained weight, though. They constantly battled hunger, cravings and binges. The investigators found at least one reason: plummeting levels of leptin. The contestants started out with normal levels of leptin. By the season’s finale, they had almost no leptin at all, which would have made them ravenous all the time. As their weight returned, their leptin levels drifted up again, but only to about half of what they had been when the season began, the researchers found, thus helping to explain their urges to eat.

Leptin is just one of a cluster of hormones that control hunger, and although Dr. Hall and his colleagues did not measure the rest of them, another group of researchers, in a different project, did. In a one-year study funded by Australia’s National Health and Medical Research Council, Dr. Joseph Proietto of the University of Melbourne and his colleagues recruited 50 overweight people who agreed to consume just 550 calories a day for eight or nine weeks. They lost an average of nearly 30 pounds, but over the next year, the pounds started coming back.




Dr. Proietto and his colleagues looked at leptin and four other hormones that satiate people. Levels of most of them fell in their study subjects. They also looked at a hormone that makes people want to eat. Its level rose.

“What was surprising was what a coordinated effect it is,” Dr. Proietto said. “The body puts multiple mechanisms in place to get you back to your weight. The only way to maintain weight loss is to be hungry all the time. We desperately need agents that will suppress hunger and that are safe with long-term use.”

370, 400, 460, 485

Mr. Cahill, 46, said his weight problem began when he was in the third grade. He got fat, then fatter. He would starve himself, and then eat a whole can of cake frosting with a spoon. Afterward, he would cower in the pantry off the kitchen, feeling overwhelmed with shame.

Over the years, his insatiable urge to eat kept overcoming him, and his weight climbed: 370 pounds, 400, 460, 485.
“I used to look at myself and think, ‘I am horrible, I am a monster, subhuman,’” he said. He began sleeping in a recliner because he was too heavy to sleep lying down. Walking hurt; stairs were agony. Buying clothes with a 68 waist was humiliating.

“I remember sitting in a dressing room one day, and nothing would fit. I looked at the traffic outside on the street and thought, ‘I should just run out in front of a car.’”

He eventually seized on “The Biggest Loser” as his best chance to lose enough weight to live a normal life. He tried three times and was finally selected.

Before the show began, the contestants underwent medical tests to be sure they could endure the rigorous schedule that lay ahead. And rigorous it was. Sequestered on the “Biggest Loser” ranch with the other contestants, Mr. Cahill exercised seven hours a day, burning 8,000 to 9,000 calories according to a calorie tracker the show gave him. He took electrolyte tablets to help replace the salts he lost through sweating, consuming many fewer calories than before.

Eventually, he and the others were sent home for four months to try to keep losing weight on their own.

Mr. Cahill set a goal of a 3,500-caloric deficit per day. The idea was to lose a pound a day. He quit his job as a land surveyor to do it.

His routine went like this: Wake up at 5 a.m. and run on a treadmill for 45 minutes. Have breakfast — typically one egg and two egg whites, half a grapefruit and a piece of sprouted grain toast. Run on the treadmill for another 45 minutes. Rest for 40 minutes; bike ride nine miles to a gym. Work out for two and a half hours. Shower, ride home, eat lunch — typically a grilled skinless chicken breast, a cup of broccoli and 10 spears of asparagus. Rest for an hour. Drive to the gym for another round of exercise.

If he had not burned enough calories to hit his goal, he went back to the gym after dinner to work out some more. At times, he found himself running around his neighborhood in the dark until his calorie-burn indicator reset to zero at midnight.

On the day of the weigh-in on the show’s finale, Mr. Cahill and the others dressed carefully to hide the rolls of loose skin that remained, to their surprise and horror, after they had lost weight. They wore compression undergarments to hold it in.

Mr. Cahill knew he could not maintain his finale weight of 191 pounds. He was so mentally and physically exhausted he barely moved for two weeks after his publicity tour ended. But he had started a new career giving motivational speeches as the biggest loser ever, and for the next four years, he managed to keep his weight below 255 pounds by exercising two to three hours a day. But two years ago, he went back to his job as a surveyor, and the pounds started coming back.



Soon the scale hit 265. Mr. Cahill started weighing and measuring his food again and stepped up his exercise. He got back down to 235 to 240 pounds. But his weight edged up again, to 275, then 295.

His slow metabolism is part of the problem, and so are his food cravings. He opens a bag of chips, thinking he will have just a few. “I’d eat five bites. Then I’d black out and eat the whole bag of chips and say, ‘What did I do?’”

Brain Sets the Calories

Dr. Lee Kaplan, an obesity researcher at Harvard, says the brain sets the number of calories we consume, and it can be easy for people to miss that how much they eat matters less than the fact that their bodies want to hold on to more of those calories.

Dr. Michael Rosenbaum, an obesity researcher at Columbia University who has collaborated with Dr. Hall in previous studies, said the body’s systems for regulating how many calories are consumed and how many are burned are tightly coupled when people are not strenuously trying to lose weight or to maintain a significant weight loss. Still, pounds can insidiously creep on.

“We eat about 900,000 to a million calories a year, and burn them all except those annoying 3,000 to 5,000 calories that result in an average annual weight gain of about one to two pounds,” he said. “These very small differences between intake and output average out to only about 10 to 20 calories per day — less than one Starburst candy — but the cumulative consequences over time can be devastating.”

“It is not clear whether this small imbalance and the resultant weight gain that most of us experience as we age are the consequences of changes in lifestyle, the environment or just the biology of aging,” Dr. Rosenbaum added.

The effects of small imbalances between calories eaten and calories burned are more pronounced when people deliberately lose weight, Dr. Hall said. Yes, there are signals to regain weight, but he wondered how many extra calories people were driven to eat. He found a way to figure that out.

He analyzed data from a clinical trial in which people took a diabetes drug, canagliflozin, that makes them spill 360 calories a day into their urine, or took a placebo. The drug has no known effect on the brain, and the person does not realize those calories are being spilled. Those taking the drug gradually lost weight. But for every five pounds they lost, they were, without realizing it, eating an additional 200 calories a day.

Those extra calories, Dr. Hall said, were a bigger driver of weight regained than the slowing of the metabolism. And, he added, if people fought the urge to eat those calories, they would be hungry. “Unless they continue to fight it constantly, they will regain the weight,” he said.

All this does not mean that modest weight loss is hopeless, experts say. Individuals respond differently to diet manipulations — low-carbohydrate or low-calorie diets, for example — and to exercise and weight-loss drugs, among other interventions.

But Dr. Ludwig said that simply cutting calories was not the answer. “There are no doubt exceptional individuals who can ignore primal biological signals and maintain weight loss for the long term by restricting calories,” he said, but he added that “for most people, the combination of incessant hunger and slowing metabolism is a recipe for weight regain — explaining why so few individuals can maintain weight loss for more than a few months.”

Dr. Rosenbaum agreed. “The difficulty in keeping weight off reflects biology, not a pathological lack of willpower affecting two-thirds of the U.S.A.,” he said.

Mr. Cahill knows that now. And with his report from Dr. Hall’s group showing just how much his metabolism had slowed, he stopped blaming himself for his weight gain.

“That shame that was on my shoulders went off,” he said.
