Another Canadian Obesity Summit Exceeds Expectations

Wow, what a week!

Just back from the 5th Canadian Obesity Summit, there is no doubt that this summit will live long in the minds (and hearts) of the over 500 attendees from across Canada and beyond.

As anyone would have appreciated, the future of obesity research, prevention and practice is alive and kicking in Canada. The over 50 plenary review lectures as well as the over 200 original presentations spanning basic cellular and animal research to health policy and obesity management displayed the gamut and extent of cutting-edge obesity research in Canada.

But, the conference also saw the release of the 2017 Report Card on Access to Obesity Treatment for Adults, which paints a dire picture of treatment access for the over 6,000,000 Canadians living with this chronic disease. The Report Card highlights the virtually non-existant access to multidisciplinary obesity care, medically supervised diets, or prescription drugs for the vast majority of Canadians.

Moreover, the Report Card reveals the shocking inequalities in access to bariatric surgery between provinces. Merely crossing the border from Alberta to Saskatchewan and your chances of bariatric surgery drops from 1 in 300 to 1 in 800 per year (for eligible patients). Sadly, numbers in both provinces are a far cry from access in Quebec (1 in 90), the only province to not get an F in the access to bariatric surgery category.

The presence of patient champions representing the Canadian Obesity Network’s Public Engagement Committee, who bravely told their stories to a spell-bound audience (often moved to tears) at the beginning of each plenary session provided a wake up call to all involved that we are talking about the real lives of real people, who are as deserving of respectful and effective medical care for their chronic disease as Canadians living with any other chronic disease.

Indeed, the clear and virtually unanimous acceptance of obesity as a chronic medical disease at the Summit likely bodes well for Canadians, who can now perhaps hope for better access to obesity care in the foreseeable future.

Thanks again to the Canadian Obesity Network for hosting such a spectacular event (in spectacular settings).

More on some of the topics discussed at the Summit in coming posts.

The Weight Of Living

weight-of-livingIn its approach to addressing weight bias and discrimination, the Canadian Obesity Network recently launched the “Weight of Living” (WoL) project on its facebook page.

Modelled on “Humans of New York”, WoL presents images and stories of Canadians living with obesity in all their diversity and variation.

After all, nothing is more effective in breaking down stereotypes and barriers than realizing that people living with obesity are no different from everyone else, in their hopes, their dreams, their challenges, their aspirations – doing their best to cope and overcome what life throws at them.

Rather than promoting a culture of fat-shaming and blaming, the Canadian Obesity Network seeks to destigmatise those living with obesity by encouraging them to share their real stories in their own words.

Thus, this project seeks to dismantle the stereotypes that surround the lives of people who live with obesity, including the notion that everyone who has overweight or obesity wants to lose weight because they are unhappy with themselves.

Many of the stories you will see in the upcoming weeks do not reflect this. The Canadian Obesity Network hopes that, by sharing these experiences, we all will realize that people who have overweight or obese have goals, dreams, and aspirations just like everyone else, and that their weight is not necessarily a barrier to achieving these, nor is it something that needs to be a source of fear and shame.

In contrast to many other “weight-loss” sites, the Canadian Obesity Network will not publish stories that glorify weight loss journeys, commercial programs or products, or extreme weight loss attempts.

“While we respect the importance and validity of each story we receive, publishing stories like these only serve to reinforce the idea that people who are overweight or obese are living unhappy, unfulfilling lives – and we know you are worth so much more than that.”

Check out the first WoL stories here, herehere, and here

Arguments For Calling Obesity A Disease #2: It Is Driven By Biology

feastContinuing in my miniseries on reasons why obesity should be considered a disease, I turn to the idea that obesity is largely driven by biology (in which I include psychology, which is also ultimately biology).

This is something people dealing with mental illness discovered a long time ago – depression is “molecules in your brain” – well, so is obesity!

Let me explain.

Humans throughout evolutionary history, like all living creatures, were faced with a dilemma, namely to deal with wide variations in food availability over time (feast vs. famine).

Biologically, this means that they were driven in times of plenty to take up and store as many calories as they could in preparation for bad times – this is how our ancestors survived to this day.

While finding and eating food during times of plenty does not require much work or motivation, finding food during times of famine requires us to go to almost any length and risks to find food. This risk-taking behaviour is biologically ensured by tightly linking food intake to the hedonic reward system, which provides the strong intrinsic motivator to put in the work required to find foods and consume them beyond our immediate needs.

Indeed, it is this link between food and pleasure that explains why we would go to such lengths to further enhance the reward from food by converting raw ingredients into often complex dishes involving hours of toiling in the kitchen. Human culinary creativity knows no limits – all in the service of enhancing pleasure.

Thus, our bodies are perfectly geared towards these activities. When we don’t eat, a complex and powerful neurohormonal response takes over (aka hunger), till the urge becomes overwhelming and forces us to still our appetites by seeking, preparing and consuming foods – the hungrier we get, the more we seek and prepare foods to deliver even greater hedonic reward (fat, sugar, salt, spices).

The tight biological link between eating and the reward system also explains why we so often eat in response to emotions – anxiety, depression, boredom, happiness, fear, loneliness, stress, can all make us eat.

But eating is also engrained into our social behaviour (again largely driven by biology) – as we bond to our mothers through food, we bond to others through eating. Thus, eating has been part of virtually every celebration and social gathering for as long as anyone can remember. Food is celebration, bonding, culture, and identity – all features, the capacity for which, is deeply engrained into our biology.

In fact, our own biology perfectly explains why we have gone to such lengths to create the very environment that we currently live in. Our biology (paired with our species’ limitless creativity and ingenuity) has driven us to conquer famine (at least in most parts of the world) by creating an environment awash in highly palatable foods, nutrient content (and health) be damned!

Thus, even without delving any deeper into the complex genetics, epigenetics, or neuroendocrine biology of eating behaviours, it is not hard to understand why much of today’s obesity epidemic is simply the result of our natural behaviours (biology) acting in an unnatural environment.

So if most of obesity is the result of “normal” biology, how does obesity become a disease?

Because, even “normal” biology becomes a disease, when it affects health.

There are many instances of this.

For example, in the same manner that the biological system responsible for our eating behaviour and energy balance responds to an “abnormal” food environment  by promoting excessive weight gain to the point that it can negatively affect our health, other biological systems respond to abnormal environmental cues to affect their respective organ systems to produce illnesses.

Our immune systems designed to differentiate between “good” and “bad”, when underexposed to “good” at critical times in our development (thanks to our modern environments), treat it as “bad”, thereby creating debilitating and even fatal allergic responses to otherwise “harmless” substances like peanuts or strawberries.

Our “normal” glucose homeostasis system, when faced with insulin resistance (resulting from increasingly sedentary life circumstances), provoke hyperinsulinemia with ultimate failure of the beta-cell, resulting in diabetes.

Similarly, our “normal” biological responses to lack of sleep or constant stress, result in a wide range of mental and physical illnesses.

Our “normal” biological responses to drugs and alcohol can result in chronic drug and alcohol addiction.

Our “normal” biological response to cancerogenous substances (including sunlight) can result in cancers.

The list goes on.

Obviously, not everyone responds to the same environment in the same manner – thanks to biological variability (another important reason why our ancestors have made it through the ages).

But, you may argue, if obesity is largely the result of “normal” biology responding to an “abnormal” environment, then isn’t it really the environment that is causing the disease?

That may well be the case, but it doesn’t matter for the definition of disease. Many diseases are the result for the environment interacting with biology and yes, changing the environment could indeed be the best treatment (or even cure) for that disease.

Thus, even if pollution causes asthma and the ultimate “cure” for asthma is to rid the air of pollutants, asthma, while it exists, is still a disease for the person who has it.

All that counts is whether or not the biological condition at hand is affecting your health or not.

The only reason I bring up biology at all, is to counter the argument that obesity is simply stupid people making poor “choices” – one you consider the biology, nothing about obesity is “simple”.

Arguments Against Obesity As A Disease #8: Promotes Helplessness And Hopelessness

sharma-obesity-depressionContinuing in my miniseries on arguments I hear against calling obesity a disease, I now discuss the objection, that doing so promotes a sense of helplessness or even hopelessness in people who carry extra weight.

First of all, as noted previously, carrying extra weight is NOT the definition of obesity. For someone to have obesity they need to be carrying weight that is actually due to excess or abnormal fat tissue AND there has to be some negative impact of that fat tissue on their health – otherwise they do not have obesity!.

That said, I am not sure how calling obesity on changes anything in terms of helplessness or hopelessness.

Yes, the effective options to better manage obesity are limited and most people will likely struggle simply not to gain even more weight – but that fact doesn’t change whether you call obesity a disease or not.

Indeed, there are many diseases for which we lack effective treatments (e.g. Alzheimer’s disease, multiple sclerosis), this does not make any of them any less of a disease.

As for hopelessness, just because you are diagnosed with a chronic disease doesn’t mean everything is hopeless.

In fact, there are many people living with chronic diseases that are controlled and well managed (e.g. diabetes, hypertension, sleep apnea), who do just fine (with treatment) and go on to live long and productive lives.

Obviously, we need better treatments for obesity but even without those,  people living with obesity can change the course of their disease by identifying and  addressing the root causes of their weight gain (e.g. depression, PTSD, emotional eating, etc.) and adopting behaviours, which even if not resulting in any noticeable weight loss, can markedly improve their health and well-being.

Again, whether you call obesity a disease or not is completely irrelevant to whether or not you feel helpless or hopeless – the management approach would be the same, except that hopefully it will shift attention to a chronic disease strategy that requires long-term sustainable management rather than an acute intervention that is unsustainable.

If we are serious about providing patients with help and hope, let us get serious about finding and providing better treatments for this disease.

Arguments Against Obesity As A Disease #5: Reduces Personal Responsibility

diet journalIn my miniseries on arguments that I often hear against calling obesity a chronic disease, I now turn to the objection that declaring obesity a disease would reduce or even abolish personal responsibility.

The argument being, that the term “disease” carries the connotation of being inevitable and will thus reduce motivation in patients to do anything about it.

This is complete nonsense!

When has calling something a disease ever taken away an individuals “responsibility” to do what they can to avoid or ameliorate it?

Take for example type 2 diabetes – a very avoidable and modifiable condition. Calling diabetes a disease does not mean that the individual can do nothing to prevent it or that, once it occurs, the patient can do nothing to change the course of the disease – of course they can and should and often do!

Or take people with a high risk of heart disease or lung disease or bone and joint disease or even cancer – in no instance do we expect less of patients to do their part in helping manage these conditions just because we call them “diseases”.

There is even a term for this – it is called “self-management” – a key principle of chronic disease management.

The course of almost every chronic disease can be changed by whether or not patients change their diet, follow their exercise program, monitor their symptoms, take their medications, come in for their visits – all a matter of “responsibility” if you so wish.

So just how exactly would calling obesity a disease take away from any of this?

Frankly, I cannot help but sense that people who use this argument most often, are erring on the side of “shame and blame” and probably still see obesity largely as a matter of personal “choice” rather than the complex multifactorial problem that it actually is.

Indeed, the opponents often appear “morally” opposed to the very notion of accepting obesity as a disease, as it now gives people the “excuse” to not do anything about it. Sorry, but this whole line of arguing reeks of nothing less than weight bias and discrimination.

As far as I can tell, calling something a disease often leads to exactly the opposite response – when obesity happens (and it can happen to anyone), it places a tremendous mental, physical and social burden on the people who get it – no matter what you call it.

People living with obesity have no greater or lesser “responsibility” of contributing to the self-management of their disease, than people living with hypertension, diabetes, depression, heart disease, or cancer – people living with any disease should be doing what they can – why would obesity be any different?
