Mythbusting Garcinia cambogia

>> Sunday, December 8, 2013





There are a kajillion substances, herbs, and naturopathic remedies that are all over the internet, purporting their magical abilities to cause weight loss, but which do not have evidence to support that they actually work.  You can add Garcinia canbogia to this list.

Garcinia cambogia extract comes from a type of tamarind tree native to Asia.  In addition to being available as an extract, it is also an ingredient in Hydroxycut, which has been associated with cases of liver toxicity.  Now that Dr Oz has been throwing his weight behind Garcinia, it's getting more attention than ever before.  (More on my thoughts re Dr Oz here.)

We can put to rest the controversy behind Garcinia simply by looking at the science.  A randomized controlled trial was conducted long ago, back in 1998, showing that Garcinia cambogia failed to produce significant weight loss compared to placebo.

Friends, today's blog is short and not so sweet: Garcinia cambogia has been proven NOT to work, and it may be harmful.

A little Friday Fun.  Check it out - as part of a campaign to make Russians healthier, and also to promote the Sochi Olympic Winter Games, the Moscow Metro is offering metro tickets for 30 squats (instead of the usual price of 30 rubles).  I love it!!

Thanks to both Mark and Erin for the double heads' up on this awesome campaign.

Taking On Dr Oz And His 15 Superfoods

>> Sunday, October 6, 2013



My colleague Dr Yoni Freedhoff pointed out a great article on his blog this week, speaking out against Dr Oz and his health claims. The article is written by pharmacist Scott Gavura, who started his own blog in response to frustrations with the growing use of pseudoscientific products and practices - in other words, use of (usually expensive) supplements and products for betterment of health that do not actually have any substantial science to support their use.

Scott goes on to do a reality check on all 15 items on Dr Oz's list of Superfoods, from raspberry ketones to green tea to chia, acknowledging the benefits of some of these substances, but also pointing out where data are lacking, and where there may also be some potential harms.

Scott echoes my own concerns about Dr Oz:

What frustrates me the most about Dr. Oz is that he should know better. He’s a heart surgeon, (who continues to treat patients), an academic, and a research scientist, with literally hundreds of publications to his name. He has gone through the peer review process more times than most health professionals. There is little reason to expect, based on his pre-television history, that he’d be willing to build a platform to offer demonstrably bad health advice. And that’s a shame, because with a show in 118 countries that reaches over 3 million viewers in the USA alone, it could be a powerful tool for providing good health information to those seeking it. And more often than not, that opportunity is squandered.

Out of respect for a colleague, I think, our profession has been quiet about Dr Oz for too long.  However, more and more, we are seeing all manner of health care professionals speak out about his inappropriate use of his title as a physician to tout supplements and substances that do not have scientific evidence behind them, and in some cases (such as in the case of the HCG diet) could do harm (read here about the potential harms of HCG).  

The sad reality is that the voice of medical bloggers speaking out against these practices is diminutive in comparison with Dr Oz's capital backing and marketing power.

A Horrifying National Post Article - Dr Sue's Radio Interview on Obesity Stigma

>> Wednesday, September 18, 2013






I was asked to interview on the Kingkade & Kelly radio talk show this week, in response to a recent article in the National Post.  The article, titled (brace yourself) 'Fat acceptance is not the answer to obesity', states that (AND I QUOTE):

"Doctors rightly resent spending time and expertise helping people whose health problems are self-inflicted"

and 

"health professionals who judge their patients are doing them a favour"

Really??  REALLY??  The National Post should be categorically ashamed of themselves for publication of such complete and utter trash.  I had a mouthful of things to say about this topic (as I'm sure you can imagine) - check out the recorded interview here!

I welcome your comments.

The Facts and Farce of Before and After Photos

>> Sunday, August 18, 2013




We've all seen them - those ads that make it look SO easy to shed pounds... just join this exercise program!  Try this supplement!  Follow this diet!  The before and after testimonial photos that show how one person's body changed on the program seem... well, too good to be true.

The truth of the matter is, these before & after pictures are often fake, and mislead the consumer to believe that they will get results that are often unrealistic.  Ways in which these pictures are made to represent something other than reality include:


  • using poor lighting for the before photo with unflattering poses, vs great light and professional modelling stances afterwards
  • having the people posing to breathe out, relax muscles, and even frown for the before photo, with a gleaming smile and all muscles taut for the after photo
  • photoshopping
  • there are reports of bodybuilders being paid to stop working out and gain as much fat as possible to take 'before' photos, then resume their regular eating habits and workouts to get buff for the 'after' shot
  • models being given potentially dangerous fat burners or supplements while they are on a particular diet or exercise program
  • models being given diuretics to dehydrate them for the after photo (to make the muscles look more 'cut')

And let's not lose track of the fact that it's not about getting that perfectly cut body.  It's about obtaining our Best Weight - a realistic weight goal (which is different for everyone) that optimizes metabolic health and overall wellbeing.  Remember that for people who struggle with obesity, a 5% to 10% sustained weight loss decreases the risk of a host of complications associated with obesity such as diabetes, obstructive sleep apnea, osteoarthritis, and high blood pressure - now there's something to be proud of!

The World's First All-Diabetic Professional Athlete Team!

>> Thursday, July 18, 2013






Here's an inspirational story to make you smile today: The recent BC Superweek's cycling race included an all diabetic racing team!

Anyone who lives with diabetes or cares for people with diabetes knows that managing diabetes in the context of exercise can be a challenge.  Managing diabetes in the context of a gruelling multi-day race is nothing short of impressive and admirable.

The attitude of this go-get-em team reflects exactly how we guide and teach our patients with diabetes:  to learn adapt their diabetes medications to fit their lifestyle, rather than have to change or restrict their lifestyle to fit their diabetes medications or insulin regimen.   Learning how to adjust certain diabetes medications or insulin doses to fit differences in activity levels and eating patterns from day to day can be a very freeing and satisfying experience!

Google's New Nutrition Search

>> Thursday, June 13, 2013





This week, Google has added a new feature to its search engine - a new nutrition database.

Now, if you type in for example 'chicken breast nutrition', you'll see the usual list of links pop up, but now, in the right of the screen, you'll also see nutrition information automatically pop up.  From there, there is a drop down menu if you want to select a different type of chicken (eg chicken thigh), and there's also a drop down box to select the desired portion size (eg per 100g, per half breast, etc).

The data is pulled mainly from the US Department of Agriculture's database.

My review so far?  Mixed at best.  It appears to be a fairly accurate (based on my searches so far) and convenient resource for searching singular/simple food products such as 'halibut', 'orange', and so forth.   However, if you search for example 'hamburger', it spits out 354 calories for 1 burger.  Of course, we know that the number of calories in a burger varies wildly, depending on the size, patty thickness, where it is purchased from, etc.  They have also not yet added any brand information, so if you try to search 'All Bran nutrition' or 'Starbucks nutrition', nothing comes up (other than the usual links).

I do give kudos to Google for taking this step in helping the public find nutritional information, but their database is currently only really useful for ingredients for recipes or very simple, singular food products.  I'd suggest not relying on any meal information (eg burger, burrito, taco etc), as these cannot be relied on due to the huge variation in the marketplace.

I know Google is working hard to improve the database, and hopefully it will become more useful for combination meals as their hard work continues.

What the World Eats

>> Thursday, June 6, 2013






I'm excited to share with you an article from The Daily Mail UK which very poignantly shows the difference in how different families eat (and what they spend on food) around the world.   Journalists visited 30 countries and asked regular families to take photos of what they would bring home from the grocery store to eat in a typical week.


One of the top scores for a balanced diet, in my books, goes to the Egyptian family pictured above.  Note the proportion of veggies relative to meat!  Leaner cuts of meat (or fish) would be preferred, and I'd switch up the pop for water (or diet pop at least), but overall they are doing pretty well.  I must say that when I travelled Egypt years ago with my best friend Deb, I remember enjoying lots of healthy (and very tasty) meals - it's amazing what Bedouins can whip up in the middle of the desert under a starlit sky.




Now let's visit a family in Bhutan (above).  Again, lots of veggies, but definitely lacking in protein sources, likely due to lack of accessibility.  (Thankfully, the WHO Bhutan program has been working on improving nutritional issues in this country including anemia and protein energy malnutrition.)





Family Japan (above) is doing a great job, with excellent protein sources (lots of fish), though they could go a little heavier on the vegetables.  Japan has one of the lowest obesity rates in the world. There are many things we can learn from how the Japanese prepare their food as well, and how this thoughtful preparation can result in lower calorie intake - see my thoughts re the bento box here.




Now let's contrast family USA (above) with family Egypt (at the top).  Note the dramatic difference in prepackaged foods, sore lack of vegetables in the US family's weekly shop, and the carbs, fat, and fast food that dominate the American diet.  Notice also how much food the US family of 4 consumes in a week, compared to the food consumed by Egyptian family of 12!  USA has one of the highest obesity rates on the planet.



And how did family Canada do?  Interestingly, the journalists chose a family from Nunavut, represented above.  I'm pleased to see not too much packaged food, some great fish protein, but again, vegetables fill far less of the table than many other countries' families studied.


Clearly, these families are just one from each country, and what different families consume in each country will vary greatly.  What families around the world are able to purchase also depends heavily on both physical accessibility, as well as the cost of food.  Note from the article that the cost of family Egypt's food was 43 GBP (about $66 USD) for the week, whereas the green peppers and tomatoes on that table alone would cost at least that much in Canada. (This cost has to be balanced against the typical income in each country as well, so.... it's complicated!)  However, it is very interesting and educational to have a flip through all of the countries studied in the article itself, and to ponder how the typical food choices of each family relate to the prevalence of obesity in each of their countries.


Enjoy!

New York Soda Size Ruling - Politics Win Over Sound Health Policy

>> Sunday, April 7, 2013









In the midnight hour (literally), a restriction on sugary drink size that was about to go into effect in New York was struck down by a judge.  Health care providers across the continent heaved a sigh of disappointment and sadness, as this move was widely viewed as a leadership step in making some important societal changes to help manage the obesity endemic.

The New England Journal of Medicine published an excellent editorial discussing the decision.  I'd love to hear what you think about this - please submit your comments and ideas by clicking on the comments link at the bottom of this blog! (subscribers, you'll need to click on the title link of this email to go to my website to do this)
