Fat Chance
Robert Lustig
Sugar is addictive, toxic and everywhere. Find out how your sweet tooth might be nibbling you to death in this straight-talking exposé.
‘Fat Chance’, documents the science and the politics that has led to the pandemic of metabolic syndrome – which results in conditions like obesity, diabetes and heart disease. Dr Robert Lustig exposes how changes in the food industry and in our wider environment have affected our collective metabolisms and our waistlines, and he shows how industry and political forces, motivated by greed, don’t want things to change.
To help us lose weight and recover our health, Lustig presents personal strategies to readjust the key hormones that regulate hunger and reward and suggests societal strategies to improve the health of the next generation. Discover how every calorie is different and that cutting out sugar is not just about making us thin – it’s about making us healthier, happier and smarter.

Dedication
This book is dedicated to all the obese patients worldwide who suffer daily, and the family members who suffer with them. The children who will not know a normal childhood, who will endure an inhuman existence, and will die a slow and early death. The parents who are engulfed by guilt. The unborn children, who are already imprisoned by changes in their brains and their bodies. But most of all, I dedicate this book to those of you who are or have been my patients; for it is you who taught me the science of your affliction. You also taught me more than medical school ever did or could; and that each life is valuable, precious, and worth saving. You maintained your dignity in the face of the most adverse circumstances imaginable. You shared with me your misery, and your joy in small victories. We cried and we laughed together. I hope I was of some service and comfort.
This book is my way of returning the favor.
This book is written only for those of you who eat food.
The rest of you are off the hook.
INTRODUCTION: Time to Think Outside the Box
“We just eat too damn much.”
Governor Tommy Thompson (R-Wisc.), U.S. Secretary of Health and Human Services, Today, NBC, 2004
Indeed we do. That’s it, thanks for buying this book, you’ve been a great audience, I’m outta here.
Well, that’s what the U.S. government would have you believe. All the major U.S. governmental health agencies, the Centers for Disease Control (CDC), the U.S. Department of Agriculture (USDA), the Institute of Medicine (IOM), the National Institutes of Health (NIH), and the U.S. Surgeon General, say that obesity results from an energy imbalance: eating too many calories and not getting enough physical activity. And they are right – to a point. Are we eating more? Of course. Are we exercising less? No doubt. Despite knowing this, it hasn’t made any difference in the rates of obesity or associated diseases. More to the point, how did this epidemic happen and in such a short interval of just thirty years? People say, “The food is there,” and it is. But it was there before. People say, “The TV is there,” and it is. But it was there before, and we didn’t have this caloric catastrophe. There’s more to this story, way more, and it’s not pretty.
Everyone blames everyone else for what has happened. No way is it their fault. Big Food says it’s a lack of activity due to computers and video games. The TV industry says it’s our junk food diet. The Atkins people say it’s too many carbohydrates; the Ornish people say it’s too much fat. The juice people say it’s the soda; the soda people say it’s the juice. The schools say it’s the parents; the parents say it’s the schools. And since nothing is for sure, nothing is done. How do we reconcile all these opinions into a cohesive whole that actually makes sense and creates changes for the better for each individual and for all society? That’s what this book is about.
Food is not tobacco, alcohol, or street drugs. Food is sustenance. Food is survival. Most important, food is pleasure. There are only two things that are more important than food: air and water. Shelter’s a distant fourth. Food matters. Unfortunately, food now matters even more than it should. Food is beyond a necessity; it’s also a commodity, and it has been reformulated to be an addictive substance.
This has many effects on our world: economically, politically, socially, and medically. There is a price to pay, and we’re paying it now. We pay with our taxes, our insurance premiums, and our airline fares – nearly every bill we receive in the mail has an obesity surcharge that we underwrite. We pay in misery, worsening school scores, social devolution, and we pay in death. We pay for all of it, one way or another, because the current food environment we have created does not match our biochemistry, and this mismatch is at the heart of our medical, social, and financial crisis. Worse yet, there is no medicine for this. There is no edict, ordinance, legislation, tax, or law that can solve this alone. There is no quick fix, but the problem is resolvable if we know what’s really going on – and if we really want to resolve it.
In his 2004 book Food Fight, Kelly Brownell of Yale University talks about obesity and the “toxic environment” we now live in, a euphemism for our collective bad behaviors. I am going a step further. I’m interested in whether there is something actually toxic, I mean poisonous, going on here. Even laboratory animal colonies have been getting fatter over the past twenty years!
Every good story needs a villain. While I am loath to reveal it this early in the book, I won’t keep you in suspense. It’s sugar – the Professor Moriarty of this story, a substance that now permeates nearly all food and drink worldwide. It’s killing us…slowly, and I’ll prove it. Every statement throughout this book is based on scientific study, historical fact, or recent statistics.
I’m a physician. We take an oath: primum non nocere (first do no harm). But there’s a paradox in this statement: when you know the final disposition – that the outcome is going to be bad – then doing nothing is causing harm.
I certainly did not start out as an advocate. I wasn’t looking for a fight. I didn’t come to this controversy with a preconceived agenda. Indeed, I was fifteen years into my medical career before I stepped up to deal with obesity as an issue. Until 1995, like my medical colleagues, I did my best to avoid seeing obese patients. I had nothing to tell them except “it’s your fault” and “eat less and exercise more.” At that time, seeing an obese child with type 2 diabetes was an anomaly. Now it is an almost everyday occurrence. The problem of obesity is now inescapable in medical practice. You can’t avoid it any more.
The concepts elaborated here didn’t just wake me from sleep one day in a divine revelation. This book is the culmination of sixteen years of medical research, medical meetings, academic discourse with colleagues, journal clubs, policy analysis, and a whole lot of patient care. I have no conflict of interest in espousing the information here; I am not a pawn of the food industry or a mouthpiece for any organization. Unlike many authors addressing the devastation of obesity, I don’t have a product line designed to enrich my bank account. I came by these views honestly and through rigorous data analysis. And the data are out there for everyone to examine. I’m just putting them together somewhat differently.
As a scientist, I have personally contributed to the understanding of the regulation of energy balance. As a pediatrician, I get to watch the interaction between genetics and environment that causes obesity play out in my examining room every day. And now, as a fledgling policy wonk, I have seen how the changes in our society have sprouted this global pandemic. It is this panoramic view that allows me to connect the dots for you, and they don’t connect in the way you’ve been told.
To blame obesity on the obese is the easy answer, but it is the wrong answer. The current formulation of gluttony and sloth, diet and exercise, while accepted by virtually everyone, is based on faulty premises and myths that have taken hold in the world’s consciousness. Obesity is not a behavioral aberration, a character flaw, or an error of commission. When we think about the ravages of obesity, our minds often go first to adults. But what about kids? One quarter of U.S children are now obese; even infants are tipping the scales! Children don’t choose to be obese. They are victims, not perpetrators. Once you understand the science, you realize what applies to children also applies to grown-ups. I know what you’re thinking: adults are responsible for their own choices and for the food they give their children. But are they?
An esteemed colleague involved in the obesity wars once said to me, “I don’t care what’s causing the obesity epidemic. I just want to know what to do about it.” I respectfully disagree. In order to pull ourselves out of this ditch, we have to understand how we drove into it. Indeed, our current thinking is based on correlation, supposition, and conjecture. I wrote this book to persuade you, the reader, to take up this cause, for your own health and for our country’s. However, you can’t truly advocate for a cause unless you know what is going on. And you can’t disagree with me until you know all the facts. And that means the science. After you’ve read this book, if you think it’s a crock or that I’m a crank, tell me. I want to know. In fact, I’ll make a promise to you right now: there is not one statement made in this entire book that can’t be backed up by hard science. My reputation in the field is built on the science. It’s also my protection against those who would try to discredit me, including the food industry and, as you will see, the federal government. Indeed, it’s the only reason I haven’t been discredited yet. And I won’t be, because I stick to the science. Now and forever.
However, in four places in the book, I let my imagination run wild. I will try to explain how obesity fits within the process of evolution, how our evolutionary biochemistry works to keep us alive, and finally how our food environment has altered that biochemistry to promote this global catastrophe. These fits of speculation will carry the section heading “Deconstructing Darwin.”
This book is targeted at the patients who suffer, the doctors who suffer along with them, the U.S. electorate who pays for this debacle, the politicians who must take up arms to dig us out of the mess that has been created out of our economy and our health, and the rest of the world, so they don’t make the same mistakes (although they already have).
In Part 1 of this book, I will challenge some of the theories you’re used to hearing in the media, and indeed from the medical profession. Parts 2 and 3 will focus on the science of obesity, and how the body deals with energy burning versus storage. No, you don’t need to be a biology or medical expert to understand the science. I’ve worked hard to reduce it down to its essence, and to keep it interesting, light, and accessible. In Part 2, I’ll also explain how your brain has developed, evolutionarily and in utero, to thwart your attempts at dieting. You truly are hormonal when it comes to the foods you crave, just not in the ways you think. Part 3 will elaborate on the science of fat tissue, and when and how it can make you sick. In Part 4, I will prove that our current environment is indeed “toxic.” I will show how the “American diet,” which is now the “industrial global diet,” is killing us…slowly. I will identify the poison and the antidotes, why those antidotes work, and why they’ve been added to or removed from our diet for the food industry’s purposes. Part 5 elaborates what you, as an individual, can do to protect yourself and your family by changing your “personal environment.” Finally, in Part 6, I argue that governments around the world have been co-opted by the food industry, and I will outline how they must instead partner with the populace and exert influence over the food industry to stop the obesity pandemic before we all reach the medical and financial Armageddon now within sight.
PART I
The Greatest Story Ever Sold
Chapter 1
A Fallacy of Biblical Proportion
Juan, a 100-pound six-year-old Latino boy whose mother is a non-English-speaking farm worker from Salinas, California, comes to my clinic in 2003. He is wider than he is tall. I ask the mother in my broken Spanish, “I don’t care what your kid eats, tell me what he drinks.” No soda, but a gallon of orange juice per day. On calories alone, this accounts for 112 pounds per year of body fat. Of course, some of that is burned off, and it might influence total food intake. I explain to the mother, “La fruta es buena, el jugo es malo (the fruit is good, the juice is bad). Eat the fruit, don’t drink the juice.” She asks, “Then why does WIC [Women, Infants, and Children, a government entitlement program for the poor run by the U.S. Department of Agriculture] give it to us?”
One kid, one mother, one question, my life was changed – and the need for this book was born. Why does WIC give it to them? There is real science behind our worldwide obesity catastrophe. And science should drive policy, but as you will see, the politics get in the way. This is the most complex issue facing the human race this side of the Middle East conflict. And it has become incrementally more complicated over time, with multitudes of stakeholders with set agendas, and bigger than the individual parties involved. Devoid of simple solutions, it has destroyed families and claimed the lives of countless people.
You can’t pick up a newspaper or log on to the Internet without seeing some new statistic on the obesity pandemic. It’s all obesity, all the time. And how many of them have something good to report? You can bet that any tabloid headline is about one of two things – either the statistics are getting worse or another obesity drug was denied or withdrawn by the Food and Drug Administration. I’m sure you’re sick of it. I know I am. And weight loss has turned into a blood sport – just tune in to The Biggest Loser.
In 2001, Newsweek reported that six million kids in America were seriously overweight. We have tripled that number in a decade, and the numbers are now surpassing twenty million. Yet for all the media attention, visibility, discussion, and weight loss programs, even Michelle Obama can’t put the genie back in the bottle.
While we’re getting fatter, we’re also getting sicker. Our risk for illness is increasing faster than the increase in obesity. Indeed, the cluster of chronic metabolic diseases termed metabolic syndrome – which includes obesity, type 2 diabetes, hypertension (high blood pressure), lipid (blood fat) disorders, and cardiovascular (heart) disease – is snowballing by leaps and bounds. And then there are the other obesity-associated metabolic diseases, such as nonalcoholic fatty liver disease, kidney disease, and polycystic ovarian syndrome. Add to that the other comorbidities (related medical conditions) associated with obesity, such as orthopedic problems, sleep apnea, gallstones, and depression, and the medical devastation associated with the obesity pandemic is staggering. Every one of these diseases has become more prevalent over the past thirty years. What’s more, all of them are now found in children as young as five years old. We even have an epidemic of obese six-month-olds![1 - J. Kim et al., “Trends in Overweight from 1980 Through 2001 Among Preschool-Aged Children Enrolled in a Health Maintenance Organization,” Obesity 14 (2006): 1164–71.]
The human damage in this scourge of metabolic syndrome is showing. In 2005 one study showed that despite the increased availability of medical care, our children will be the first generation of Americans who will die earlier than their forebears.[2 - S. J. Olshansky et al., “A Potential Decline in Life Expectancy in the United States in the 21st Century,” New Engl. J. Med. 352 (2005): 1138–45.] The study placed the blame squarely on the obesity epidemic. In the United States, quality-adjusted life years lost to obesity have more than doubled from 1993 to 2008. Emergency rooms are taking care of forty-year-old heart attack victims. Teens with type 2 diabetes used to be unheard of; now they are one third of all new diagnoses of diabetes. In the United States alone, 160,000 bariatric surgeries (to reduce the size of the stomach) are performed per year, at an average cost of $30,000 per surgery. Over 40 percent of death certificates now list diabetes as the cause of death, up from 13 percent twenty years ago.
The loss in American productivity due to time off from work is staggering, the waste in medical expenditures ($147 billion per year) is breaking the bank, and this amount is predicted to increase to $192 billion by the end of the decade. Guess what? There’s no money to pay for it all. The Affordable Care Act (ACA, or “Obamacare”) is going to put thirty-two million sick people on the insurance rolls by 2019. The president says we’ll make up for the costs in savings from preventative care. However, it is unlikely to improve our health in any significant way, as there are no provisions for the prevention of chronic disease, most notably those that attend obesity. How do you prevent all the ravages of chronic metabolic disease when we bust the scales and when the statistics show no sign of improvement? It’s often been said that we wouldn’t need health care reform if we had obesity reform.
It would be one thing if obesity were an isolated problem in America, but it’s happening everywhere. The obesity pandemic has expanded the world’s collective waistline. The World Health Organization (WHO) has shown that the percentage of obese humans globally has doubled in the past twenty-eight years. In fact, obesity’s contribution to the burden of chronic disease has been equal to if not greater than that of smoking. Even people in developing countries are obese. After only one decade, there are now 30 percent more people who are obese than are undernourished worldwide. The WHO reported in 2008 that approximately 1.5 billion adults were overweight and at least 400 million were obese globally[3 - World Health Organization, Fact Sheet: Obesity and Overweight (2011), www.who.int/mediacentre/factsheets/fs311/en/.]; these numbers are projected to reach about 2.3 billion and 700 million, respectively, by 2015. In September 2011 the UN General Assembly declared that non-communicative diseases (diabetes, cancer, and heart disease) are now a greater threat to world health than are infectious diseases, including in the developing world (see chapter 22). Is the whole world now composed of gluttons and sloths? Over the next fifteen years, these diseases will cost low- and middle-income countries more than $7 trillion.[4 - UN General Assembly, “Prevention and Control of Non-Communicable Diseases,” New York, 2010.] People are dying earlier, and national economies are losing billions of dollars in lost productivity while governments pay for the medical expenditures. Millions of families end up in poverty, guaranteeing that the cycle will not be reversed.
For the 55 percent of adults who are overweight or obese, listen up. I’m talking to you, at a doctor-to-patient level, at a person-to-person level. Obesity is not an automatic death sentence. A full 20 percent of morbidly obese persons are metabolically healthy and have normal life spans.[5 - J. M. Chan et al., “Obesity, Fat Distribution, and Weight Gain as Risk Factors for Clinical Diabetes in Men,” Diabetes Care 17 (1994): 961–69.] As for the other 80 percent, you don’t have to be in poor health; everyone has it within his reach to improve his health and regain those years the actuaries say will be lost. But success in doing so depends on identifying the cause of the problem, assessing your metabolic risk, and changing your biochemistry. Okay, full disclosure: despite your best efforts, you may never lose your stubborn subcutaneous fat (the fat that pads your thighs and derrière). And if you do, you’ll gain it back in short order – unless you become a gym rat, because vigorous exercise is the only rational way to prevent weight regain (see chapter 13). In fact, if you lose meaningful amounts of subcutaneous fat and keep it off for more than a year, I’ll be shocked. Pleasantly so, but shocked nonetheless.
For the 45 percent of adults who are normal weight, pay attention. You either sneer at or pity the other 55 percent of your brethren who take up two seats on the bus. You look down on them as weak, overindulgent, and lazy. You resent them, and you show it financially and socially. You’re indignant that they cost you money. And you think you’re out of the woods and home free. You’ve been told that you’ll live a long and happy life. Whatever you’re doing, it must be right. For those of you who are “naturally” thin, you’ve been told that you have great genes and can consume all the soft drinks and Twinkies you want without gaining a pound or getting sick. Would that it were true. A few years ago, you were the majority of Americans. Now you’re the minority. And you’re losing your percentage year by year.
This means that many of you are flipping – that is, gaining weight and going over to the dark side. Indeed, current projections suggest that by 2030, the United States will be 65 percent overweight and 165 million American adults will be obese.[6 - S. L. Gortmaker et al., “Changing the Future of Obesity: Science, Policy, and Action,” Lancet 378 (2011): 838–47.] The 2008 movie Wall-E is a prophecy: that’s where we’re all headed. We’ll all be so fat, we’ll have to ride around on little scooters, just like at Walmart. And as you get older, your risk for gaining weight keeps going up. Your genes won’t change, but your biochemistry will. So, if you’re flipping (which more and more of you are), something must be sending you over to the “dark side.” And if that’s not your fate, it will be that of your children. Nobody knows this better than I, because I take care of those children every day.
Here’s the kicker. Being thin is not a safeguard against metabolic disease or early death. Up to 40 percent of normal-weight individuals harbor insulin resistance – a sign of chronic metabolic disease – which will likely shorten their life expectancy. Of those, 20 percent demonstrate liver fat on an MRI of the abdomen (see chapter 8).[7 - K. C. Sung et al., “Interrelationship Between Fatty Liver and Insulin Resistance in the Development of Type 2 Diabetes,” J. Clin. Endocrinol. Metab. 96 (2011): 1093–97.] Liver fat, irrespective of body fat, has been shown to be a major risk factor in the development of diabetes. You think you’re safe? You are so screwed. And you don’t even know it.
The overriding thesis of this book is that your fat is not your fate – provided you don’t surrender. Because people don’t die of obesity per se. They die of what happens to their organs. On the death certificate, the medical examiner doesn’t write down “obesity”; instead it’s “heart attack,” “heart failure,” “stroke,” “diabetes,” “cancer,” “dementia,” or “cirrhosis of the liver.” These are diseases that “travel” with obesity. They are all chronic metabolic diseases. But normal-weight people die of these as well. That’s the point. It’s not the obesity. The obesity is not the cause of chronic metabolic disease. It’s a marker of chronic metabolic disease, otherwise known as metabolic syndrome. And it’s metabolic syndrome that will kill you. Understanding this distinction is crucial to improving your health, no matter your size. Obesity and metabolic syndrome overlap, but they are different. Obesity doesn’t kill. Metabolic syndrome kills. Although they travel together, one doesn’t cause the other. But then, what causes obesity? And what causes metabolic syndrome? And what can you do about each? Read on.
I wrote this book to help you and your kids get healthy and improve your quality of life, increase your productivity, and reduce the world’s waste of medical resources. If you get thin in the process, great. But if that’s what you expect, go find your own diet guru, and good luck with that. Want to get healthier? Want to get happier? Want to get smarter? It’s your visceral (around your abdominal organs) fat and hepatic (liver) fat that’s keeping you down. And getting rid of visceral fat is not as hard as you might think. This is the more metabolically active fat, and there’s plenty you can do to shrink it.
A proverb says, “A journey of a thousand miles begins with a single step.” This book is a journey into the workings of the body. It is a journey into the biochemistry of our brains and our fat cells. It is a journey into evolution, the mismatch between our environment and our biochemistry. And it is a journey into the world of business and politics, too. This journey starts with a single but very large step, in which we abandon our current thinking of obesity by challenging the age-old dogma “a calorie is a calorie.”
Chapter 2
A Calorie Is a Calorie – or Is It?
“If folks want to maintain a healthy weight, they have to be sensitive to the calories in and calories out…Not every calorie is the same.”
Governor Tom Vilsack (D-Iowa), U.S. Secretary of Agriculture, upon release of the 2010 Dietary Guidelines, January 13, 2011
Wait a second. If people have to be sensitive to calories in and out, then why aren’t calories the same? Does anyone see the contradiction here? This was the first time that any government official had even remotely hinted that calories might not be interchangeable, and it was buried in this cryptic double-speak.
Everyone is a dietitian. Everyone thinks he or she understands obesity. Believe it or not, this is one of the harder medical conditions to comprehend. Why? Obesity is a combination of several factors: physics, biochemistry, endocrinology, neuroscience, psychology, sociology, and environmental health, all rolled up into one problem. The factors that drive the obesity pandemic are almost as myriad as the number of people who suffer from it.
The Venus Von Willendorf is an eleven-inch statue carbon-dated to 22,000 BCE that was unearthed in Austria in 1908 (see figure 2.1). It depicts the torso of a morbidly obese adult woman. This shows us that the ancients knew about obesity long before they knew about fast food. There are other ways to gain weight aside from potato chips and pizza, soda and suds. The medical literature lists at least thirty diagnoses that include obesity as a symptom. These include problems of the brain, liver, and adipose (fat) tissue; genetic disorders; various hormonal imbalances; and the effects of certain medications.
But none of these medical causes explain what’s happened to the world’s population over the last thirty years. Until 1980, statistically only 15 percent of the adult population had a body mass index – or BMI, an indicator of body fatness that is calculated from a person’s weight and height – above the eighty-fifth percentile, indicating either overweight or obesity. Now that statistic is 55 percent. And by 2030 it’s expected to be 65 percent.[8 - S. L. Gortmaker et al., “Changing the Future of Obesity: Science, Policy, and Action,” Lancet 378 (2011) 838–47.] Something’s happened in the last thirty years, but what?
Fig. 2.1. A Venus FatTrap. The Venus von Willendorf is an 11-cm-high statuette of a female that carbon-dates to between 24,000 and 22,000 BCE. It was discovered in 1908 in Austria, and is on display in the Naturhistorisches Museum in Vienna. It shows that obesity is as old as man (or woman) himself.
The First Law
In order to understand obesity, and energy balance in general, we must acquaint ourselves with the first law of thermodynamics, which states, “The total energy inside a closed system remains constant.” For you math and science geeks:
U = Q – W
where U is the internal energy of a system, Q is the heat supplied by the system, and W is the work done by the system. Work and heat are due to processes that either add or subtract energy; when work = heat, the internal energy stays constant. The first law is a law. It is elegant and airtight. If you don’t like it, file a grievance with Sir Isaac Newton. I subscribe to the first law. The basis for our current understanding of the causes and consequences of the obesity pandemic lies not with the first law itself, but rather in how you interpret it, for, as with all laws, there is plenty of room for alternative interpretations.
The prevailing wisdom on the first law can be summed up by one widely held dogma: a calorie is a calorie. That is, to maintain energy balance and body weight (the U in the equation), one calorie eaten (the Q) must be offset by one calorie burned (the W). The calorie eaten can come from anywhere, from meat to vegetables to cheesecake. The calorie burned can go to anywhere, from sleeping to watching TV to vigorous exercise. And from this dogma comes the standard and widely held interpretation of the first law: “If you eat it, you had better burn it, or you will store it.” In this interpretation, the behaviors of increased energy intake and decreased energy expenditure are primary (and presumably learned); therefore, the weight gained is a secondary result. Thus, obesity is routinely thought to be the natural consequence of these “aberrant behaviors.” As you will see hereafter, virtually all the stakeholders in the obesity pandemic have signed up on the side of personal responsibility.
The Seating Chart at the Table of Blame
The Head of the Table: The Gluttons and the Sloths
Personal responsibility occupies the biggest seat at the Table of Blame. The common assumption in obesity hinges on its being a personal choice: We control what we eat and how much we exercise. If you are obese, it must be because you chose to either eat more, exercise less, or both. Over the past twenty-five years, various government agencies have accumulated ample evidence of the increased caloric intake during that time frame, both in children and in adults. During this time, the CDC has documented that Americans have increased their caloric consumption by an extra 187 calories per day for men, 335 calories per day for women. The behaviors associated with the rise in obesity include increased consumption of sugar-sweetened beverages and decreased consumption of whole fruits, vegetables, and other sources of dietary fiber. On a societal level, obesity is also associated with less breastfeeding, skipped breakfasts, fewer family meals, and more fast food dining. Alternatively, a wealth of evidence supports a role for decreased physical activity and increased “screen time” (TV, computers, video games, and texting) in causing obesity.
It is from this perception of choice that we derive our current societal mantras around obesity: gluttony and sloth, two of the original “seven deadly sins.” I should note here that people exhibiting the other five deadly sins (greed, pride, lust, envy, and wrath) have gotten a pass in the press and in society as a whole. They are frequently extolled in the media – just watch the reality shows The Apprentice (envy, greed, pride, wrath—“You’re Fired!”), Millionaire Matchmaker (lust, greed, pride), or Jersey Shore (all known sins and then some).
We’ve found absolution for nearly every vice and sin we can commit, except for these two. They continue to defy our society’s ability to forgive. This despite the fact that 55 percent of Americans are either overweight or obese. Thin people are now in the minority, yet our culture continues to punish the majority. The average woman in the United States wears a size 14, yet many stores do not carry anything above a size 10. Although many women’s clothing stores now have “vanity sizes” (what was a size 10 in 1950 is now labeled a size 6), a large percentage of the population still can’t find anything on the rack. Approximately ten years ago in San Francisco, a billboard advertising the local 24-Hour Fitness health club depicted an extraterrestrial with the tag line “When they come, they’ll eat the fat ones first.”
Our society continues to glorify thinness even though it appears to be less achievable every year. Those of us who are overweight or obese are immediately assumed to be gluttons and/or sloths. The obese are passed over for employment because it’s assumed they’ll be as lazy on the job as they are in caring for their bodies. They are among the last groups about which you can still make pejorative comments in public. From this condemnation, it’s a quick jump to the determination that obese people became so due to a behavioral defect. This formulation serves many purposes. It certainly justifies society’s desire to place blame.
Even the obese have bought into the thesis of personal responsibility (see chapter 20). They would prefer to be portrayed as “perpetrator” rather than “victim.” If you’re a perpetrator, you maintain control and make your own choices, which is more hopeful than the alternative. If, instead, you’re a victim, you have no power, obesity is your fate, and there is no hope. You’re doomed, which is far more depressing. Finally, “personal responsibility” serves as the cornerstone of both the government’s and the insurance companies’ restriction of obesity care delivery.
Seat 2: The Health Insurance Industry
Much of the public views doctors as moneymaking mountebanks who care less for their patients than for their wallets. Well, we lose money on every patient we see. While our hospital’s general pediatric health insurance reimbursement averages 37.5 cents on the dollar (a pittance), our pediatric obesity clinic collects only 29.0 cents per dollar billed. The reason for this? The health insurance industry refuses to pay for obesity services, saying, “Obesity is a behavior, a flaw in your character, a psychological aberration. And we don’t pay for behavior.” This is the reason that, despite having enough business many times over, childhood obesity clinics and treatment programs are closing across the country. The insurance industry has decided that obesity is a lifestyle choice; therefore, it won’t pay. And when insurance companies do pay, they pay the absolute minimum.
The insurance industry hates this obesity epidemic almost as much as we doctors do. They are hunkering down for a long siege. Why do they continue to deny reimbursement for obesity services? Because if they paid for all the services required by today’s pandemic, it would break their piggybank. Instead, they keep plugging holes in the dike by ascribing blame to the individual. They know that if they ever admit that obesity is the fault of no one person, the waters will engulf them all.
Seat 3: The Medical Profession
Twenty years ago, obesity was a social issue, not a medical one. At the beginning of my career, a colleague in pediatric endocrinology (the study of hormones in children) would send a form letter to the parents of children referred for obesity that read, “Dear parent, thank you for your interest in our pediatric endocrinology division. Your child has been referred for obesity. Obesity is a problem of nutrition and activity, not one of endocrinology. We suggest that you seek general advice from your child’s pediatrician.” And despite the undeniable onslaught of patients referred, many of my colleagues still feel this way.
As the problems have soared and the research dollars have poured in, the American Diabetes Association (ADA), the American Heart Association (AHA), and countless others professional organizations have devoted a substantial portion of their agendas to the obesity pandemic. The standard mantra espoused by the medical establishment is, “Lifestyle causes obesity, and obesity causes metabolic syndrome.” We doctors recognize our role in mitigating the negative effects of obesity. But, again, for most physicians, the behaviors come first. The fault still lies with the patient.
Seat 4: The Obesity Profiteers
They say, “You’re weak. You’ve failed. Let us help you.” They profess to have the answer for your obesity problem and are peddling one solution or another. They are the obesity profiteers, and they represent large and vast industries, most of which are ostensibly trying to “do the right thing,” while making a fortune in the process. We have the otherwise reputable peer-group weight-loss programs such as Weight Watchers and Jenny Craig, which strongly recommend the option of buying their trademarked cuisine (often loaded with sodium) to bolster profits. There are the diet supplement people such as Nutri-System, who demand that you purchase their food if you want to see results. Gym programs such as Curves and 24-Hour Fitness charge initiation and renewal fees for membership. Then there are the companies that make home exercise equipment. Their late-night infomercials invariably show a buff guy stretching a rubber band with the implicit message, “You can look like this if you stretch a rubber band.” And then we have the “obesity authors” (gee, I’m one now!). Some are M.D.s, some Ph.D.s, some journalists, some pop culture phenomena, and some charlatans (none of which is mutually exclusive). All profess to have the answer to your obesity problem, peddling one diet or another. A few of these authors have developed corporations that want to sell you their food line, such as Atkins or the Zone. And each provides just enough science and nuggets of truth to hook the public.
Some weight-loss doctors and clinics peddle prescription appetite suppressants or other weight-loss remedies – all of which are paid for out of pocket. Some of these doctors are reputable and brilliant academics at medical universities who are trying to save people’s lives while studying the physiology of obesity. Some are surgeons who perform liposuction for cosmetic purposes and bariatric surgery for metabolic and cardiac rescue. But some of them are “cut-and-run” surgeons operating out of small airplanes and flying around to little towns to perform quickie lap-band surgeries or gastric bypasses. They take their victims’ money, have no quality control, never see the patient in follow-up, and sometimes leave medical catastrophes in their wake.
While the insurance companies refuse to shell out funds for this problem, the research money is pouring in. The pharmaceutical industry has spent a lot of money to come up with the “obesity blockbuster,” that magic bullet that will work long-term and for everyone. But that’s a pipe dream because, first, obesity isn’t one disease, it’s many; second, our bodies have many redundant pathways to maintain our critical energy balance, so one drug can’t possibly be effective for everyone; and third, there’s no one drug that will treat metabolic syndrome (see chapter 19).
Each of these people and industries have one thing in common: they are trying to make a buck off the misfortunes of the obese, to the tune of $117 billion a year. And they’re all charging retail. Out of pocket, cash on the barrelhead. No insurance reimbursements here. No discounts. In case you hadn’t noticed, the obese will do anything not to be obese, even throw their money away on “get-thin-quick” schemes. That’s why these industries are the obesity profiteers. Do any of their “solutions” work? Fat chance. If you just did what they told you, the fat would magically disappear. If it fails, it’s your fault – you must have been noncompliant! Yet another reason for the obese to be depressed. Think about it – if any of these books, diets, or programs actually worked for the entire population, there would be only one. The person who makes this discovery will likely win the Nobel Prize, move to a mansion in Tahiti, and be featured on Lifestyles of the Rich and Famous.
