Pick the 'Diet' That Works For You!

>> Sunday, February 22, 2015




For those of you who have been following my blog posts about some of the popular diet plans out there, you may be wondering.... where does this leave you?!

To round out this discussion, I'd like to draw your attention to a recent meta-analysis of data in the Journal of the American Medical Association, which compared data on a wide range of weight loss diets of 3 months' or longer duration.   They found that there was very little difference between the weight loss on each diet, on the order of a couple of pounds or less.

The point is that there is no one particular diet plan that works best for everyone - it is a matter of finding the diet plan that will work for you, on a permanent basis.  To engage in a temporary diet is most often pointless and often even a setback in the longterm, as most often these efforts result in weight regain (and then some) after the diet plan is stopped.

So, when you are looking at permanent lifestyle changes to make, ask yourself - are these changes that you can make and stick to for the rest of your life?  Finding the right personalized formula for you, to best answer this question, is key.  Bringing a nutritionist or dietitian on board can be helpful to get you set in the right direction.  Remember to speak with your family doctor before making any changes, particularly if you take medication to treat diabetes, or if you have any medical problems such as kidney or heart problems.

Sniffing Out Inhaled Insulin

>> Monday, February 16, 2015






In an effort to find alternative ways to administer insulin apart from the current standard of injecting it under the skin, a new inhaled insulin has recently been made available in the United States.

Called Afrezza, the inhaled insulin is taken at mealtime, and is used instead of fast-acting insulin injection at mealtimes (it does not replace the need for long acting insulin in those who need it).  It is rapidly absorbed by the lungs, has its peak action at under an hour, and is gone in 2.5 to 3 hours (a little faster than the fast acting mealtime injectable insulins currently available).

While clinical trials have been done, showing that the inhaled insulin is comparable in efficacy to mealtime injectable insulin in type 1 and type 2 diabetics, these studies have been criticized in that diabetes control in these studies was not as tight as recommended by diabetes guidelines (ie, hemoglobin A1C of 7% or less).  


There are a number of additional concerns with inhaled insulin, including:

1.  Dose increments are large (it has to be adjusted by 4 unit increments, whereas injectable insulin can be adjusted by as little as 0.5 unit increments).  This makes it harder to fine-tune blood sugar control.

2.  Inhaled insulin cannot be used in smokers or people with lung disease (such as asthma).

3.  Inhaled insulin causes a small decrease in lung capacity (forced expiratory volume).   Lung function has to be monitored in people using inhaled insulin.


My take:  Due to the concerns above, I don't see this as a game changer in diabetes care.  Should this inhaled insulin become available in Canada, I will continue to recommend the currently available injectable mealtime insulins to my patients.  That being said, for people who are very resistant to the idea of taking an injectable mealtime treatment, this could offer an (inferior) alternative way to give insulin to those people - ie, it may be a better alternative to no mealtime insulin at all in people who need it.

Jenny Craig - Dr Sue's Review

>> Sunday, February 8, 2015







This week, I’m reviewing one of the most popular diet plans out there – Jenny Craig. 

Jenny Craig essentially works by taking the thinking out of eating – you eat prepackaged food in accordance with a planned menu that is provided to you.  Members have access to individualized, private counselling sessions, and a combination of recommendations for both nutrition and physical activity is provided.

As members move along in the program, the diet loosens up a little bit, allowing 1-2 days per week with non-Jenny foods.

The Jenny program has been shown to be effective in clinical trials.  A two year randomized clinical trial has shown that the Jenny diet is effective to reduce weight compared to a control group who received standard dietary counselling.   Jenny Craig has also been studied in type 2 diabetics, showing better diabetes control and more weight loss at 1 year, compared to a group receiving standard care.

The biggest plus I see about the program is that it teaches portion control, in that members can see from the portions provided what an appropriate meal size should be.  It is also a balanced diet, with the menu plans created in accordance with the USDA Dietary Guidelines.

The biggest downside I see is that this is not a permanent lifestyle change.  A person cannot order Jenny's food for the rest of their lives (nor would it be recommended to, particularly re the salt content).  So what happens when a person stops the diet?  The vast majority return to previous cooking and eating habits, and the weight goes back up.  Yes, if a Jenny Craig graduate takes the learnings about portion control into the future and continues this in a lifelong fashion, it may be possible to keep the weight off afterwards – but this isn’t the reality for most.

Another concern is cost.  There’s an enrolment fee of about $50, followed by a monthly fee of about $30, and the daily food cost comes in between $15-22 according to the website.  Another down side is salt intake, which is quite high in some of the meals that are provided.

Dr Sue's bottom line: While it is clinically proven in the short term and does teach portion control -  it's not a permanent lifestyle change, so I don't recommend it.

Canadian Obesity Task Force Guidelines: What's Missing

>> Sunday, February 1, 2015








Last week, new guidelines for the prevention and management of obesity in primary care in Canada were published by the Canadian Task Force on Preventive Health Care in the Canadian Medical Association Journal.

Unfortunately, it is not exactly a 'solutions based' document.   The main recommendations are as follows:

1.  Body mass index (BMI) should be calculated by family doctors to help prevent and manage obesity.

2.  Structured programs should not be offered to adults of normal weight, to prevent weight gain.

3.  For adults with overweight or obesity, structured programs should be offered to help with weight loss.

4.  Medications should not be used to treat obesity.


While I could pick apart their focus on BMI, or that not offering preventive programs was (in their words) a weak recommendation based on very low quality evidence, I want to focus on their recommendation not to use medications to treat obesity.

Advising us against using medications to treat obesity may be short sighted.  While Canada currently has very little in terms of medications to treat obesity, several medications have been approved in the last three years by the FDA in the United States to treat obesity, some of which may become approved for use by Health Canada as well.  Will the guidelines be hastily rewritten if/when these medications become available to us? Advising against medications to treat obesity leaves us with lifestyle measures on one end of the spectrum, and bariatric surgery on the other end.  While the US and Europe move forward in accepting obesity as a medical problem with medication options to treat it, is Canada going to stay in the dark ages on this?  Note that while our Task Force is telling us not to use medications to treat obesity, that the Endocrine Society in USA simultaneously released their Clinical Practice Guideline about how to treat obesity with medications.  While I agree that the current singular medication available to treat obesity in Canada (orlistat) is not very useful, a note that options may change in the near future may have given this section a little more balance.

Another concern I have with these guidelines: Discussion of bariatric surgery was conspicuous in its complete absence.  While bariatric surgery is an extreme treatment measure for obesity, it is a valuable one, and of great benefit for some patients.  It is stated that these guidelines are not intended for patients with a BMI over 40 (bariatric surgery is considered an option if BMI is >40, or >35 with complications of obesity), but I feel that at least a head nod to the existence of bariatric surgery should have been given in this document.

And - how does one exclude people with BMI >40 from the guidelines, when one in eight Canadian adults who struggle with obesity fall into this category?

The procedure that leads to creation of guidelines is a rigorous review of evidence, and I get that this is why these guidelines look the way they do - lifestyle intervention studies and evidence are poor, medication options in Canada are currently limited, and availability of bariatric surgery is minimal compared to the number of people who could benefit from these procedures.

However, as an advocate (warrior?) for my patients who struggle with excess weight, I will continue to remain optimistic that more options and accessibility will ultimately become available to Canadians to treat this condition.
