5th Canadian Obesity Summit – Four More Days To Submit Your Abstracts!

banff-springs-hotelEvery two years the Canadian Obesity Network holds its National Obesity Summit – the only national obesity meeting in Canada covering all aspects of obesity – from basic and population science to prevention and health promotion to clinical management and health policy.

Anyone who has been to one of the past four Summits has experienced the cross-disciplinary networking and breaking down of silos (the Network takes networking very seriously).

Of all the scientific meetings I go to around the world, none has quite the informal and personal feel of the Canadian Obesity Summit – despite all differences in interests and backgrounds, everyone who attends is part of the same community – working on different pieces of the puzzle that only makes sense when it all fits together in the end.

The 5th Canadian Obesity Summit will be held at the Banff Springs Hotel in Banff National Park, a UNESCO World Heritage Site, located in the heart of the Canadian Rockies (which in itself should make it worth attending the summit), April 25-29, 2017.

Yesterday, the call went out for abstracts and workshops – the latter an opportunity for a wide range of special interest groups to meet and discuss their findings (the last Summit featured over 20 separate workshops – perhaps a tad too many, which is why the program committee will be far more selective this time around).

So here is what the program committee is looking for:

  • Basic science – cellular, molecular, physiological or neuronal related aspects of obesity
  • Epidemiology – epidemiological techniques/methods to address obesity related questions in populations studies
  • Prevention of obesity and health promotion interventions – research targeting different populations, settings, and intervention levels (e.g. community-based, school, workplace, health systems, and policy)
  • Weight bias and weight-based discrimination – including prevalence studies as well as interventions to reduce weight bias and weight-based discrimination; both qualitative and quantitative studies
  • Pregnancy and maternal health – studies across clinical, health services and population health themes
  • Childhood and adolescent obesity – research conducted with children and or adolescents and reports on the correlates, causes and consequences of pediatric obesity as well as interventions for treatment and prevention.
  • Obesity in adults and older adults – prevalence studies and interventions to address obesity in these populations
  • Health services and policy research – reaserch addressing issues related to obesity management services which idenitfy the most effective ways to organize, manage, finance, and deliver high quality are, reduce medical errors or improve patient safety
  • Bariatric surgery – issues that are relevant to metabolic or weight loss surgery
  • Clinical management – clinical management of overweight and obesity across the life span (infants through to older adults) including interventions for prevention and treatment of obesity and weight-related comorbidities
  • Rehabilitation –  investigations that explore opportunities for engagement in meaningful and health-building occupations for people with obesity
  • Diversity – studies that are relevant to diverse or underrepresented populations
  • eHealth/mHealth – research that incorporates social media, internet and/or mobile devices in prevention and treatment
  • Cancer – research relevant to obesity and cancer

…..and of course anything else related to obesity.

Deadline for submission is October 24, 2016

My Critical Review Of Critical Fat Studies: Obesity In Canada

obesity-in-canada-coverA few weeks ago, I was invited by the Editor of The Lancet Diabetes & Endocrinology to review Obesity in Canada, a collection of articles by Canadian and Australian authors, who identify themselves as “fat scholars” engaging in “critical fat studies”. (Edited by Jenny Ellison, Deborah McPhail, and Wendy Mitchinson).

Obviously, I have had multiple interactions with “fat scholars” over the years and have certainly always learnt a lot.

Indeed, I would be the first to admit that many of my own ideas about obesity, including the issue of whether or not obesity is a disease and, if so, how to define the clinical problem of obesity in a manner that does not automatically label a quarter of the population as “diseased”, has been shaped by this discourse.

Similarly, my own notions about obesity management, with a primary goal to improve health and well-being rather than simply moving numbers on the scale, are clearly influenced by ideas that first emerged from the “fat acceptance camp” (not exactly the same, but close enough).

Thus, there was certainly much in this compendium that I was already quite familiar with – which certainly made the reading of this 500 page volume most enjoyable.

Nevertheless, it is important to realise that “fat scholars” do not just see themselves as “scientists” – rather, they see the practice of “fat studies” as a political work, tightly (some might say dogmatically) bound to a frame of reference that is reminiscent of political “activism” rather than “science”.

Fat scholars (at least the ones represented in this volume) are not just critical of, but also appear most happy to discard the entire biomedical and population health discourse around obesity, as nothing more than (I paraphrase), “a thinly-veiled conspiracy by the biomedical establishment to create a moral panic that justifies the reassertion of normative identities pertaining to gender, race, class, and sexuality.

Accordingly, some fat scholars appear to be of the rather strong opinion that there is in fact no “global obesity epidemic” and even if there are perhaps a few more fat people around today than ever before, the health consequences of obesity are vastly overblown, and any recommendations or attempts to lose weight are not only ineffective but actually harmful.

Now, before you simply roll your eyes and decide to file away the whole exercise in the drawer that you reserve for global-warming deniers and anti-vaxxers, let me assure you that there is indeed a lot to be learnt from the discourse (at least I did).

For one, there are absolutely fascinating chapters on the history of fat activism in Canada (which apparently dates back to the early 70s), enlightening perspectives on Indigenous People’s encounters with obesity, the issue of “mother blaming”, and even a chapter on fat authenticity and the pursuit of hetero-romantic love in Vancouver.

There are stories about how kids and families experience childhood obesity intervention programs and how primary school teachers themselves struggle with being thrust into a role of being role models while struggling with their own personal response to the pervasive obesity messages.

Obviously, there are some ideas that may be harder to swallow than others.

Take for e.g, the notion that the “root cause” of fat phobia (at least according to fat scholars who rely on postmodern feminism, psychoanalysis, and queer theories), is simply a reflection of the femininity ascribed to body fat: because women need fat to menstruate, body fat can be seen as female reproductive material that, in patriarchy, must be contained, restrained, and ultimately eliminated.

Personally, I can no doubt think of a wide range of other “root causes” that would result in “fat phobia” and “weight stigma” without having to quite delve into feminism or queer theories – but that’s another story.

Or the notion that there is in fact no link between body fat and diabetes – something that is easily refuted by a host of experimental animal studies and clinical observations  (which, in the world of “fat scholars” do not appear to exist or are for some opaque reason deemed entirely irrelevant for the discourse).

Nevertheless, these “peculiarities” aside, I do admit that I found the book a very timely, relevant and enlightening read for anyone who is seriously interested in the issue of obesity and bold enough to step out beyond the typical biomedical discourse.

I would most certainly recommend this volume to people working in health policy and public health but also to clinicians, who seek to better understand some of the social aspects of the obesity discourse as it relates to their patients.

There is much in the volume that I perhaps disagree with or rather, see from a different perspective (I am after all a clinician) – however, openness to entertaining alternative views and ideas, and willingness to shift your own opinion and beliefs when new evidence emerges, is the defining characteristic of good scholarship – and I certainly remain a lifelong student.

Stereotypical Stigmatizing Case Histories Are Not Useful For Teaching Doctors About Obesity

living-in-usa-spiral400bYesterday, I posted about the “Clinical Discussion” of obesity management, presented to us by the venerable New England Journal of Medicine.

I wrote about how the ignorant and moralizing “opinion” of one of the discussants, devoid of even the smallest insight in to the complex sociopsychobiology of this chronic disease, is exactly the kind of “thinking” that is holding back the field (and has been for decades).

But these are not the only problems with the “Clinical Discussion”.

Rather, the problems start with the very choice and description of the “case”.

Indeed, the case warrants a careful line-by-line analysis, to reveal just how the use of the “stereotypical” depiction paints a picture of what (as we will see in a later post), could well turn out to be a much more complicated case than either of the discussants acknowledge.

As we are told,

Ms. Chatham is a 29-year-old woman who recently joined your practice; this is her second visit to your clinic.

In other words, this is a young woman, whose life you know virtually nothing about, not that this should ever stop you from stating your sound medical opinion.

She made today’s appointment to discuss how she can lose weight and whether there are medications that she can take to aid in weight loss.

In other words, a typical “fat” patient looking for a “quick fix” via “diet pills”?

She is relatively healthy, except for a history of childhood asthma.

Did the asthma play any role in her weight gain? Did it limit her physical activity as a kid? Was she on anti-allergic drugs or even systemic steroids that may have led to weight gain? Your guess is as good as mine.

She says that she has been told indirectly, by her friends and family, that she is “overweight.”

Because, obviously, she does not own a mirror, never shops for clothes, and has probably never given her shape or size a second thought, and therefore, needs to be “told” by the good people around her (and perhaps on occasion by perfect strangers she may just happen to meet on the street), that she has a serious health problem and needs to urgently see a doctor.

She has tried several popular diets without success; each time, she has lost 4.5 to 6.8 kg (10 to 15 lb) but has been unable to maintain the weight loss for more than a few months.

Which, I’m guessing, simply goes to prove her lack of motivation and effort. Obviously, like most “fat” people, she is just too weak-willed to maintain weight loss and apparently always gives up far too soon. Never mind, that this is exactly what happens to 95% of people (skinny or fat) who lose weight and never mind, that (as some of us now realise) there is in fact a complex neurohormonal physiology, which tightly regulates body weight and is there solely for the purpose of effectively “defending” against weight loss.

She does not have a history of coronary artery disease or diabetes.

Which would in fact be surprising, given that she is a 29 year-old woman!

She has a regular menstrual cycle.

Which means what exactly? Are we supposed to rule out PCOS or fertility issues based on this clinical “pearl”?

She does not take any medications or nonprescription supplements.

So at least we know that she cannot simply blame her weight gain on any current medications.

She does not smoke but does drink alcohol, occasionally as many as 4 or 5 drinks in a week, when she is out with friends.

Which you could also say about millions of other people (including myself), irrespective of their BMI or health status – it’s what people do!

She tells you that she “watches what she puts in her mouth”…

Which, of course we should have a hard time believing, because as we all know, “fat” people are habitual liars when it comes to what they “tell” us about their diets.

…and reads the nutritional labels on food packaging.

or, at least that’s what she “tells” us – you’re welcome to believe her or not.

However, she enjoys eating out and orders take-out meals 8 to 12 times a week.

Wow! Here we have a “fat” person who actually “enjoys” eating out – as many times as (hold your breath) once or twice a day – and that, despite claiming to read food labels! Never mind that this is exactly how 99.9% of the US population happens to eat (no matter what their size or health status) – clearly, this irresponsible behaviour must change if there is to be any hope for her!

She works as a computer programmer and spends most of her day sitting in an office.

There we have it – typical “sedentariness” a well-known “cause” of obesity (or so we are told), because (as should be obvious to anyone who understands the complexity of energy homeostasis), all people who sit in offices (not to mention the now immortalised 400 lb “hacker”), struggle with their weight.

She belongs to a fitness club and tries to go there about once a week but notes that her attendance is inconsistent.

Because, of course, it’s typically the fat people with gym memberships, who never show up for training. Also relevant, because most of us continue to believe that exercise is the best way to lose weight.

On physical examination, her vital signs are unremarkable except for a blood-pressure measurement of 144/81 mm Hg.

Which we must obviously assume to be reliable, as the docs have certainly ruled out the presence of “White-Coat” hypertension and bothered to ensure that they are indeed using an appropriate cuff size.

She is 1.7 m (5 ft 7 in.) tall and weighs 92 kg (203 lb), and her body-mass index (BMI; the weight in kilograms divided by the square of the height in meters) is 32.

Which contains about as much clinically valuable information as telling us that she is a size 16.

Her waist circumference is 94 cm (37 in.).

Another piece of useless information, especially in an otherwise healthy woman.

There is no peripheral edema.

Which, I guess, clearly tells us that she can forget about using “fluid retention” as an “excuse” for her weight.

The rest of the examination is unremarkable.

There you have it – with this information in hand, we are now clearly poised to give her meaningful clinical advice to help her better manage her weight.

What surprises me about this (apparently “typical”) case history, is that the editors of the New England Journal of Medicine, otherwise so concerned with brevity, did not simply decide to shorten the “case” to the following:

“Ms. Chatham is a pretty healthy 29-year-old working woman, who happens to live in the USA.”

That one line would in fact contain about all of the information we now have about Ms. Chatham, the difference being, that this statement is actually better, in that it is elegantly crafted to avoid the use of “stereotypical” fat-shaming language and imagery.

Furthermore, this sentence, quite like the “case”, is also void of any indication of the actual complexity that even “simple obesity” can present in clinical practice (which, I perhaps mistakenly, assumed would have been the whole point of the Clinical Discussion in the first place).

Is anyone curious as to the information that I would really liked to have about Ms. Chatham to come up with advice that would actual help her?

Then, please stay tuned for tomorrow’s post.

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 #9: Medical Education

sharma-obesity-medical-students1Next in my miniseries on the pros and cons of calling obesity a ‘disease’, I turn to the issue of medical education.

From the first day in medical school, I learnt about diseases – their signs and symptoms, their definitions and classifications, their biochemistry and physiology, their prognosis and treatments.

Any medical graduate will happily recite the role and function of ADH, ATP, ANP, TSH, ACTH, AST, ALT, MCV and a host of other combinations of alphabet soup related to even the most obscure physiology and function – everything, except the alphabet soup related to ingestive behaviour, energy regulation, and caloric expenditure.

Most medical students and doctors will never have heard of POMC, α-MSH, PYY, AgRP, CART, MC4R, or any of the well studied and long-known key molecules involved in appetite regulation. Many will have at best a vague understanding of RMR, TEE, TEF, or NEAT.

The point is, that even today, we are graduating medical doctors, who have at best a layman’s understanding of the complex biology of appetite and energy regulation, let alone a solid grasp of the clinical management of obesity.

Imagine a medical doctor, who has never heard of β-cells or insulin or glucagon or GLUT4-transporters trying to manage a patient with diabetes.

Or a medical doctor, who has never heard of renin or aldosterone or angiotensinogen or angiotensin 2 trying to manage your blood pressure.

How about a medical doctor, who has never heard of T3 or T4 or TSH managing your thyroid disease?

Elevating obesity to a ‘disease’ means that medical schools will no longer have an excuse to not teach students about the complex sociopsychobiology of obesity, its complications, prognosis, and treatments.

As I mentioned in a previous post, suddenly, managing obesity has become their job.

No longer will it be acceptable for doctors to simply tell their patients to control their weight, with no stake in if and how they actually did it.

Thus, if there is just one thing that calling obesity a ‘disease’ can change, it is expecting all health professionals to have as much understanding of obesity as they are currently expected to have of diabetes, heart disease, lung disease, and any other common disease they are likely to encounter in their medical practice.

Apparently, simply treating obesity as a ‘lifestyle’ problem or ‘risk factor’ was not enough – hopefully, recognising obesity as a  ‘disease’ in its own right, will change the attention given to this issue in medical training across all disciplines.
