The Chariot jogging/cycling/skiing stroller is what every parent needs to stay active

A few months ago my wife gave birth to our first baby.  It’s been a steep learning curve.  As expected, getting much physical activity has been tough at times.

However, the single most helpful tool we’ve had has been our Chariot jogging stroller (disclosure: this fawning review is completely unsolicited).  It can be used as a jogging stroller, a bike trailer, and the wheels can even be swapped out for skis if you want to take it snowshoeing or skiing.

See the video below for a quick overview of the Chariot (this is the two-seater version, although I personally have the 1 seater, which is considerably more narrow, which makes it more useful as an actual stroller).

Dear Parents/Grandparents: Your Toddler Does Not Need a Screen for Christmas

The end of civilization as we know it. (The iPotty. Source)

Christmas is upon us.  If you are a parent/grandparent/relative, you are likely scrambling for that last minute item that your child will love.  One thing I urge you to avoid: screens, and toys that incorporate screens.  Your toddler does not need a huggable iphone case, or a learning tablet, or (does this need to be said?!) an iPotty.

The research is absolutely clear: the more time that kids spend in front of screens, the worse their physical and mental health (a full review of the evidence is available here, and concluded that excess screen time was associated with excess body fat, reduced fitness, worse grades, and worse behaviour).

3 tricks for preventing holiday weight gain

holiday dinnerAlthough only 1 in 10 individuals will gain 5 lbs or more during the holidays, most of us will put on some weight that tends to stay with us during the course of the following year. Thus, to help you avoid becoming that 1 in 10 who puts on more weight than average during the next couple of weeks, here’s a list of 3 easy tricks to curb overindulging.

1. Drink 1-2 glasses of water prior to all big meals
A study published online in the journal Obesity randomized overweight/obese older men and women to either a hypocaloric diet alone or a hypocaloric diet plus increased water consumption for a duration of 12 weeks. The hypocaloric diet consisted of 1200 calories for the women and 1500 calories for the men. Those in the diet + increased water group were required to consume 500 ml of water (2 cups) 30 minutes prior to each of the 3 large daily meals (breakfast, lunch, dinner).

While participants in both groups lost a significant amount of weight (5-8kg) in response to the diet, those who also consumed more water before their meals lost an additional 2 kg in comparison to the diet only group.

The greater weight loss in the group consuming pre-meal water was likely the result of smaller caloric intake during each meal (~40 calories less per meal).

Drinking more water will also have the added bonus of forcing you to take bathroom breaks, thereby increasing your level of physical activity.

The truth about holiday weight gain

Today I’d like to revisit an issue which is becoming a bit of a holiday tradition here at Obesity Panacea. How much weight do people gain over the holidays?  

If you ask many people, they will say that the average person gains somewhere around 10 lbs, which is a pretty substantial amount (over a 10 year period, that would mean people were gaining roughly 100 lbs from the holiday season alone!).  This idea has taken root in the public imagination – see the above poster that was posted in a prominent Canadian gym chain in previous holiday seasons.

When I first heard about the above poster a few questions immediately jumped to mind:

  1. Where does this information come from? Who is the “average” person they are speaking of? Aged 18-80? Does it include kids? Seniors? Different ethnicities?
  2. If the average person gains 7-10 pounds, that means that some people are gaining much more. Is that even physically possible over a 1 or 2 week period (the definition of ‘holiday season’ varies pretty widely from person to person)? Canada has a population of roughly 33 million – if we gained an average of 9 lbs over the holidays, as a nation we are about to put on 297 million lbs this year alone!  In the USA, it would mean a collective holiday weight gain of roughly 3 billion lbs!!

This 7-10 lb weight gain statistic seems a bit strange, so I decided to look it up. Fortunately, I came across an excellent article from the New England Journal of Medicine which examines this very issue.

In defense of Santa’s weight

santa“Santa’s behaviour and public image are at odds with contemporary accepted public health messages,” argues a British Medical Journal editorial written by Dr. Scrooge and colleagues. Given Santa’s tremendous popularity, particularly among children, the authors of the editorial argue the public should become aware of some of the less-than-ideal lifestyle practices advocated by jolly St. Nick.

The first issue they raise in support of their argument is the pervasive use of Santa Claus to advertise basically everything during the holidays, especially unhealthy food choices such as Coca-Cola products (fair enough). Apparently, it was the Coca-Cola company in the 1930s that developed the contemporary image of Santa Claus that we all recognize today, including his obesity.

And just how obese is Santa?

According to NORAD, Santa Claus weighs in at 260 lbs and has a height of 5’7, putting him at a BMI of 40.7 kg/m2. Then again, we know BMI isn’t all that useful anyway.

The authors worry that Santa’s image “promotes a message that obesity is synonymous with cheerfulness and joviality.”

The past US surgeon general is quoted as saying: “It is really important that the people kids look up to as role models are in good shape, eating well and getting exercise. It is absolutely critical.”

Time to combine physical activity, sedentary behaviour and sleep guidelines into one holistic guideline?

Sitting is bad for you.  Exercise is good for you.  Sleep is too.

At present, we have 3 separate guidelines targeting these 3 separate behaviours.  However, when combined these behaviours make up the full 24 hour period, so it seems a bit strange to separate them out into separate and distinct constructs, especially since they all interact and influence each other (e.g. more screen time means less sleep, more activity means more sleep, more sleep means more activity, etc).  As a result, Canada is in the process of creating guidelines which integrate sleep, activity, and sedentary behaviour to give more holistic and less fractured advice to the public/policymakers/physicians/etc.

I’ve spent the past 3 days at a meeting learning about the development of these new guidelines, and I think they are a very interesting and relevant idea.  Drs JP Chaput, Val Carson, Casey Gray and Mark Tremblay (full disclosure: friends and colleagues all) have recently released a commentary outlining the rationale for these new guidelines, which has been published in the International Journal of Environmental Research and Public Health. The article has an open access license, so I have included it in full below.  It’s only a couple typed pages long, and worth the read.

I’m interested to hear what people think of this idea, as I think it represents a very different approach to thinking about activity/inactivity than has been employed in the past.

1. Introduction

Human movement has been a necessity for survival throughout evolution. However, sitting has become the new norm in today’s environment despite the fact that we have not genetically adapted to this sedentary lifestyle (1). It is now common to refer to physical activity as having “health benefits”, even though the active state is the normal biological condition for metabolic processes (2,3). Lack of human movement should rather be perceived as “abnormal” and associated with numerous health risks (4,5).

Physical inactivity and childhood obesity represent pervasive, and arguably the greatest, health challenges to our children today (6,7). There is no easy solution to these serious public health threats and they need to be addressed by a range of strategies to maximize success. One of the strategies is to find ways to increase overall physical activity of children. However, health research has mainly focused on the impact of moderate-to-vigorous physical activity (MVPA), or even high-intensity physical activity, on various health outcomes. Although this approach has resulted in important contributions to the field, emerging evidence indicates that a broader, more inclusive and more integrated approach to understanding and promoting human movement is required to better address the current public health crisis of physical inactivity and childhood obesity.

There is no doubt that MVPA provides many important health benefits. However, MVPA only accounts for a small proportion (<5%) of the 24 hour day, even among active children and youth. In contrast, sleep (~40%), sedentary behavior (~40%) and LPA (~15%) make up approximately 95% of the day (Figure 1). Ignoring other components of the movement continuum while focusing efforts on MVPA limits our understanding of how habitual movement behaviors interact to impact children’s health. Indeed, recent efforts to address the single-minded focus on MVPA have led to a proliferation of sedentary behavior research and to the creation of the world’s first sedentary behavior guidelines for children and youth (8-10).

There is accumulating evidence that excessive sedentary behavior, particularly screen-based sedentary behavior (e.g. television viewing), has unfavorable effects on various health indicators, independent of MVPA (8,9). Likewise, short sleep duration is associated with many adverse health outcomes including obesity, type 2 diabetes, depression, suicidal ideation, and poor academic performance (11-14). This issue is of particular concern since a decrease in sleep duration has been observed over the past decades in children and adolescents (15,16). Finally, a growing body of evidence indicates that spending more waking hours in LPA compared to sedentary pursuits can provide health benefits (17-19). Reallocating sedentary time to LPA (e.g. TV watching to active play) is of substantial public health interest given that it is not feasible to participate in MVPA during all waking hours. Breaking up sedentary time with LPA is a more achievable and viable goal for increasing movement (i.e. number of steps per day) and acquiring associated health benefits than focusing solely on MVPA. However, current physical activity guidelines only focus on MVPA (and recently sedentary behavior) and do not take into consideration other important movement/non-movement behaviors that occur throughout the day. This issue is important because having one “unhealthy” movement behavior can moderate the health benefits of another. For example, the health benefits of MVPA can be mitigated if children have poor sleep habits and/or engage in excessive sedentary behavior (20). Conversely, increased physical activity could well decrease the detrimental effects of insufficient sleep and/or extended periods of sitting in some individuals (21,22).
