Every 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

Now a study by Peter Nordström and colleagues, published in JAMA Internal Medicine, reports that a higher BMI in identical twins is associated with a greater risk for type 2 diabetes but not myocardial infarction or death.
The researchers looked at data from 4,046 monzygous twin pairs with discordant BMIs (difference >0.01 units) from the nationwide Swedish twin registry.
During a mean follow-up of 12 years, the rate of myocardial infarcts and deaths were similar in the twins with lower BMI compared to their higher BMI co-twin (5.0% vs. 5.2% and 13.6% vs. 15.6%, respectively).
This lack of difference remained true even when the researchers compared the extremes of BMI discordance and only considered twins with BMI greater than 30.
In contrast, both higher BMI and greater increase in BMI since 30 years before baseline was associated with greater risk of incident diabetes.
Given that diabetes is such a powerful risk factor for cardiovascular disease, one can only wonder why this did not translate into a higher cardiovascular risk in the higher weight twins.
One possible explanation, offered by the authors is that cardiovascular risk may have been well managed in these individuals thus minimizing any increased risk due to diabetes (or other BMI associated risk factors such as dyslipidemia or hypertension).
Indeed, it would probably have required a far larger group of twins (or much longer follow-up) to fully rule out higher cardiovascular risk in these twins.
Let us also not forget that BMI is a rather lousy measure of overall cardiovascular risk.
Thus, which the study is certainly compatible with the (genetics-independant?) role of higher BMI in the risk for diabetes, it certainly should not be interpreted as demonstrating that this increased risk in benign in terms of cardiovascular disease.
No doubt, obesity is a serious global issue, affecting millions of people worldwide.
However, the focus of World Obesity Day appeared to be almost entirely on childhood obesity – particularly on its prevention through policy measures.
While that is not an unreasonable goal (no doubt food advertising to kids needs to be reigned in and the global consumption of sugar needs to be reduced), the almost exclusive focus on childhood obesity in the announcement and materials released in support of obesity day, may deserve critical analysis.
Although increasing childhood obesity is no doubt an important issue, it cannot be seen in isolation from the far more prevalent adult obesity. Indeed, most of the current obesity epidemic is attributable to weight gain in adulthood – not to weight gain in kids.
Moreover, one could very well argue that much of childhood obesity is simply a direct consequence of adult obesity.
Thus, while the focus on childhood obesity may be strategically motivated (there is indeed very little public empathy for adults living with obesity), in my opinion, the almost exclusive focus on kids sends the wrong message.
For one, while I wholeheartedly support the public health policies to address obesity, I believe that adults with obesity are as deserving of our attention as are their kids.
By ignoring the adults living with obesity in their message, I fear the World Obesity Federation is sending (or rather reinforcing) the wrong message about adult obesity.
I cannot help but read between the lines, that while governments must urgently step in to eradicate childhood obesity, the millions of adults living with this chronic disease are perhaps less worthy of our attention.
Is this because we continue to feel that adults have done this to themselves? Is it because we believe that adults should be able to conquer obesity on their own? Or, Is this because we have essentially written them off as a lost cause?
I very much do believe that the millions of mothers, fathers, husbands, wives, friends, colleagues, and neighbours living with obesity, are as deserving of our compassion and our support as are their kids.
Rather than singling out kids as apparently the only (or even most deserving) group worthy of intervention, I would have liked to see the World Obesity Federation rally around the need for world-wide recognition of all of obesity as a chronic disease.
Indeed, I would have loved to see the World Obesity Federation declare discrimination of people living with obesity in health care, education, and other settings a human rights issue.
Most importantly, I would have hoped that the World Obesity Federation would have explicitly called for an end to the widespread practice of excluding obesity treatments from medical coverage in almost all health systems, and a rallying call for better education of all health professionals (and policy makers) in the basics of obesity medicine.
Like it or not, many of the kids and adolescents with obesity that the World Obesity Federation appears so concerned about will soon be young adults with obesity, with no access to obesity treatments, confronted by a generation of health professionals who still think obesity is a “lifestyle choice”.
While I do understand that initiatives like the World Obesity Day need to focus on an issue that is most likely to garner media interest and support, I also recognise that the focus on prevention of childhood obesity is merely going after the low-hanging fruit – the least controversial topic of all.
A bolder statement, one worthy of an organisation like the World Obesity Federation, would have addressed the main issue currently facing the millions of people living with obesity every day – the fact that their problem continues to be pooh-poohed publicly and institutionally as merely a “lifestyle” issue that they can easily solve by simply deciding to eat less and move more.
It is perhaps time that the World Obesity Federation takes all of obesity seriously – that would indeed be a message that I could rally behind.
The biguanide metformin is widely used for the treatment of type 2 diabetes. Metformin has also been shown to slow the progression from pre to full-blown type 2 diabetes. Moreover, metformin can reduce weight gain associated with psychotropic medications and polycystic ovary syndrome.
Now, a randomised controlled trial by M P van der Aa and colleagues from the Netherlands, published in Nutrition & Diabetes suggests that long-term treatment with metformin may stabilize body weight and improve body composition in adolescents with obesity and insulin resistance.
The randomised placebo-controlled double-blinded trial included 62 adolescents with obesity aged 10–16 years old with insulin resistance, who received 2000 mg of metformin or placebo daily and physical training twice weekly over 18 months.
Of the 42 participants (mean age 13, mean BMI 30), BMI was stabilised in the metformin group (+0.2 BMI unit), whereas the control group continued to gain weight (+1.2 BMI units).
While there was no significant difference in HOMA-IR, mean fat percentage reduced by 3% compared to no change in the control group.
Thus, the researcher conclude that long-term treatment with metformin in adolescents with obesity and insulin resistance can result in stabilization of BMI and improved body composition compared with placebo.
Given the rather limited effective options for addressing childhood obesity, this rather safe, simple, and inexpensive treatment may at least provide some relief for adolescents struggling with excess weight gain.
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.”
