The blame for fat shaming

The main reason why obesity is such an emotionally charged issue is simply that it has become entangled with all kinds of aspersions on a person’s willpower and character. It is completely different from almost every other disease because there is always the unspoken accusation that you did it to yourself. There is always the feeling that you could have done something about it if you weren’t such a weak-willed glutton.

Many physicians unconsciously engage in “fat shaming” is that they believe that this gives patients extra ‘motivation’ to lose weight. As if the whole world was not reminding them every single day. So, who deserves the blame? The “calories in, calories out” (CICO) crowd – those physicians and researchers who have strenuously and constantly cried that “a calorie is a calorie” or “it’s all about the calories” or “eat less, move more”. Because what they actually mean, but don’t say, is “it’s all your fault”. The CICO crowd took the disease of obesity and instead of treating it with compassion and understanding, infused it with personal shame. I’m here to tell you that it’s all just a huge pack of lies.

Starch structure If you develop breast cancer, for example, nobody secretly thinks that you should have done more to prevent it. Nobody condescendingly tells you to “get with the program”. If you have a heart attack, you simply don’t face those hidden accusations. Obesity has become a disease singularly unique in its association with shame. The CICOpaths imply that it’s all your fault and if you weren’t such a loser and just listened to them, you, too could look like Brad Pitt or Julia Roberts. It’s not true. They’re really just trying to deflect the blame for the obesity epidemic from their own horrible dietary advice they’ve peddled for decades.

The problem with CICO

This CICO belief stems from a foundational error in logic. We have understood the problem of obesity as a fundamental imbalance of energy, calories. In my opinion, this is a crucial, crucial mistake. I’ve argued in my book, The Obesity Code, that this obsessive fixation on calories is incorrect. Let’s think about this. Up until the 1970s, there was little obesity. Yet people had virtually no idea how many calories they ate. They also had virtually no idea how many calories they burned. Exercise was not something you did for fun. Yet, without effort people all around the world lived without obesity. They largely ate whatever they wanted when they were hungry, and didn’t eat when they weren’t.

If almost every single person in the world was able to avoid obesity without counting calories, then how is counting calories so fundamental to weight stability since 1980? People’s bodies were able to avoid obesity for over 5,000 years, but since 1980, we need calorie counters and step counters? Hardly.

There are two main changes in the American diet since the 1970s. First, we were advised to lower the fat in our diet and increase the amount of carbohydrates. This advice to eat more white bread and pasta turned out NOT to be particularly slimming. But there’s also another problem that has largely flown under the radar. The increase in meal frequency.

In the 1970s, people largely ate three times per day – breakfast, lunch and dinner. If you were not hungry, then it was perfectly acceptable to skip a meal. That was your body telling you that you didn’t need to eat, so you should listen to your body.

By 2004, the number of meals per day had increased closer to six per day – almost double. Now, snacking was not just an indulgence, it was encouraged as a healthy behavior. Meal skipping was heavily frowned upon. What kind of Bizarro world was this? Do you need to constantly eat to lose weight? Seriously? If you don’t eat, you’ll gain weight? Seriously? It sounds backwards because it is backwards.

Survey calories

The admonishments against meal skipping were loud. Doctors and dieticians with the heavy backing of corporate $$$, told patients to never, ever skip a meal. They warned of dire consequences. Magazines blared out warnings of the problems of meal skipping. From a physiologic standpoint, what happens when you don’t eat that is really so bad? Let’s see. If you don’t eat your body will burn some body fat in order to get the energy it needs. That’s all. There’s nothing else. After all, that is the entire purpose the body carries fat in the first place. We store fat so that we can use it. So if we don’t eat, we’ll use the body fat.

As people gained more weight, the calls for people to eat more and more frequently grew louder. It didn’t actually work, but that was beside the point. As people became obese, doctors would say to cut calories and eat constantly – graze, like some dairy cow in a pasture.

But this horrible advice didn’t work. So there are two potential sources of the problem. Either the dietary advice for weight loss was bad, or the advice was good, but the person was not following it. On one hand, the problem was the doctor’s advice. On the other, it was a patient problem. Let’s break it down to the basics. Physicians and other nutritional authorities believe religiously that excess calories cause weight gain. They advise patients to eat fewer calories. Either:

  1. The “eat fewer calories” advice is wrong and doesn’t work
  2. The advice is good, but the patient could not follow it. The spirit is willing but the flesh is weak. You’ve got the dream but not the drive. Etc. Etc.

I believe that #1 is correct. Therefore, patients with obesity are victims of poor advice to eat more often, lower dietary fat in a desperate effort to reduce caloric intake. Their weight problems are a symptom of a failure to understand the disease of obesity. I do not believe they have low willpower or character. It is not different to me than treating a patient with cancer.

Blaming the victim

Many physicians and researchers believe option #2. They think the problem is not the advice. They believe the problem is the patients. Therefore, a healthy dose of fat shaming may give them the motivation to get healthy. I believe it’s the “a calorie is a calorie” people who are to blame for the phenomenon of fat shaming. They are blaming the victim because it exculpates their own failed understanding of weight gain. They believe that the obesity epidemic was the result of a worldwide collective simultaneous loss of willpower and character.

The name of this game is “blame the victim”. That way, doctors can go on believing that the advice they give is perfect. It was the patient’s fault. Does this make sense? Somewhere around 40% of the American adult population is classified as obese (BMI>30) and 70% are overweight or obese (BMI>25). Was this obesity crisis actually a crisis of weak willpower?

Drown less

Consider an analogy. Suppose a teacher has a class of 100 children. If one fails, that may certainly be the child’s fault. Perhaps they didn’t study. But if 70 children are failing, then is this more likely the children’s fault, or is it more likely the teacher’s fault? Obviously the teacher. In obesity medicine, the problem was never with the patient. The problem was the faulty dietary advice patients were given. But the CICOpaths, in their denial, have heaped the blame onto those obese patients that were the very victims of the doctor’s failure to understand obesity as a disease, and not a personal character failing.

This is why obesity is not only a disease with dire health consequences but comes with a huge slice of shame. It is a disease with dire psychological consequences. People blame themselves because everybody tells them it was their fault. Nutritional authorities throw around the euphemism ‘personal responsibility’ when what they really mean is ‘It’s your fault’. But it’s not.

The real problem is the acceptance of the underlying assumption that obesity is all about “calories in calories out”. This failed CICO mentality has pervaded our entire universe and the natural conclusion of this line of thinking is that if you are obese “it’s your fault” that you “let yourself go”. You either failed to control your eating (low willpower, gluttony) or did not exercise enough (laziness, sloth). But it is not true. I believe obesity, as I’ve written about in The Obesity Code, is not a disorder of too many calories. It’s a hormonal imbalance of hyperinsulinemia. Cutting calories when the problem is insulin is not going to work. And guess what? It doesn’t.

Not only do people with weight problems suffer all the physical health issues – type 2 diabetes, joint problems, etc., but they also get the blame for it. Blame that is unfairly targeted toward them because the advice they received to lose weight had a 99% failure rate. Should people get angry about it? Absolutely.

    The more fat that I eat, the more fat I lose. The fewer carbs I eat, the clearer my mind gets. I got healthy by not listening to medical advice.

    False information. Fact check. If you over eat you, gain weight. Period. it is not a valid comparison between weight gain and cancer.

    I've suffered depression and anxiety from other's opinions of my weight since I was a teen. Now at 60 I've finally managed to move on with the help of low carb and the knowledge from posts like this. We owe it to ourselves and others to up the compassion. This is a critical part of dealing with the obesity crisis. And likely most other issues in our lives. Thanks Dr Fung.

    If you listen to your body, while being on low carb, you will never over eat. Your body tells you when to stop. Go elsewhere with your negative comment please. There are lots of people who are happy with this information and thankful for it.

    If you fat shame somebody who already hates how they look, what do you think it accomplishes for their already broken self-esteem? Many overweight people actually eat less than many normal weight people, yet they are made to feel guilty for every bite they eat. Some people develop eating disorders, and others due to the addictive nature of high carb foods find themselves comfort eating to deal with the pain.

    Education and the proper tools to help them turn it around, and support to keep going is what's needed. Knowledge is starting to trickle out, but so many people don't even know that there is an answer and don't know where to look, and are confused by conflicting information by those in the weightloss industry.

    'Now, snacking was not just an indulgence, it was encouraged as a healthy behavior. '

    I don't know where you got this idea. If you are referring to the multi-meal plan(more than 3 times a day), that is not the same as 'snacking'. This is not encouraged nor endorsed by health professionals around the world. Snacking is never encouraged as a healthy behavior and in fact, most professionals would argue against it.

    'Let’s see. If you don’t eat your body will burn some body fat in order to get the energy it needs. That’s all.'

    Whilst it is correct that your body will burn body fat to compensate for the energy, you failed to mention the physiological change your body undergoes when you don't eat for more than 8 hours - gluconeogenesis kicks in and you might not only sacrifice fat but muscle too.

    'The real problem is the acceptance of the underlying assumption that obesity is all about “calories in calories out”.'

    Calories in calories out is not an assumption. It is just pure physical analysis derived from the law of conservation - energy can neither be created or destroyed. If you take in more energy in your body and spend less, then those additional energies must stay in your body. No one forces another individual to count exact calories in their diet, neither.

    Obesity is a far more complex issue then what you have just described. A lot of people cannot lose weight due to a variety of issues; both genetic and environments play a role. You cannot simply attribute this to the wrongness of 'calories in calories out'. You also blame excessively on other professionals and authorities who work in the same field as you, whilst subtlely promoting your own book and your own products. You describe obesity as something only you understand and can fix, whilst '99%' of other professionals who dedicated their lives of studying obesity cannot do. Sorry, you did a great job for marketing but sometimes giving out real science and information doesn't necessarily hurt your career, whilst fake ones certainly will ruin your reputation in the long run. Reputation will net you money in the future. Maybe you should do focus more on medicine and less money-greed next time.

    Dear Dr Fung,
    Thank you for trying to figure this out. I was in an automobile crash two week post op from a liver resection surgery in July of 2015. I am still trying to figure out the last issues with my neck. I finally went to an orthopedic doctor for answers today, because I have tried everything else. Instead of offering solutions, he said it was because I was overweight?! Because everyone knows being overweight is bad for your neck. Incidentally, my neck is not fat. But I felt pretty depressed having waited for months to see him, only for him to fat shame me in front of my husband and have no solutions. I was feeling a bit suicidal thinking that my life will not be any better at 53 years old.
    My father has continually harassed me about my weight, since high school (even though he was the overweight one). In high school I weighed 120 lbs and was 5'6". Funny how I eat once per day (a normal meal) I walk at least 2 Miles per day average( some days up to4 or 6) and feed cows, cats and dog, mow grass, try to
    push snow ( my thumbs have nerve damage affecting my grip and I can't lift it anymore). I have vertigo, and facial numbness and limb weakness. I needed help but what I got was fat shaming. If doctors were so smart, they would've found a solution to this problem. But they don't care. They did their 8 years of school and they're done learning. They just act like they know everything.
    You seem very nice and I appreciate the work you're doing. Maybe it can help me too?

    “People’s bodies were able to avoid obesity for over 5,000 years“
    You do realize that there have been obese people throughout history correct? In medieval times it was seen as a status symbol because it meant that you were able to afford plenty of food. People in medieval ages were able to understand the more you eat, the fatter you get. The fact you think that because peasants who worked in the field all day and could not afford an excess of food were not overweight somehow proves a “foundational error in logic” in the laws of Thermodynamics is truly terrifying. Your stupidity and ignorance is putting peoples’ lives at risk. Please rethink your life choices and never reproduce.
