Is Fat Gain a Problem or Solution?

Question mark signEarlier this year Dr Jean-Philippe Chaput and I published an editorial in the journal Bioenergetics: Open Access examining whether weight gain should be seen as a physiological problem or as merely a logical adaptation to our current environments.

JP is a prolific researcher and writer, so it was a lot of fun to be able to work with him on the paper (he gets the vast majority of credit for the article – I was very much the second author on this one).  JP is also a collaborator on several of my thesis projects, and I’m looking forward to sharing some of our other work in the near future.

Since the article is open access, I have re-published it in full below.  The original article with citation information can be found here.  And for more on this topic, be sure to check out JP’s recent paper in Obesity Reviews titled Obesity: A Disease or a Biological Adaptation.

Build your own bike desk for $4.99

Two years ago Peter reported on our friend and colleague Katya Herman, who had built herself the above bike desk for about $40 (bike not included).  All you needed was a bike, a wind/mag trainer, and the secret ingredient:

the special secret ingredient to the Herman Cycling Computer Desk is…..an ironing board. That’s right – the ironing board is not just for ironing your socks, as it can also double as a laptop stand. In case you don’t own one (like yours truly – really who irons anymore?) then you can purchase this archaic device online for under 40 dollars.

Recently Katya emailed to let us know that she has improved her design, and I thought it would be worth sharing here.

Equipment needed:

  1. Nylon strong
  2. Bungee cord
  3. IKEA Brada laptop support

Sitting for just a couple hours has measurable (and negative) health impact

Last week a fascinating study was published by SBRN member David Dunstan and colleagues in Australia, which examined the acute (e.g. short-term) impact of uninterrupted sitting on metabolic health.  In this new study, individuals with overweight or obesity were asked to perform 3 separate conditions in random order.

  1. Uninterrupted sitting – participants sat for 5 consecutive hours
  2. Sitting plus light intensity breaks – similar to the uninterrupted sitting condition, except that participants had a 2 minute walk break at a light intensity every 20 minutes throughout the day
  3. Sitting plus moderate intensity breaks – similar to the light intensity breaks condition, except that the breaks were at a moderate intensity

The figure below nicely demonstrates the basic protocol for the three conditions.

Canada Releases Physical Activity and Sedentary Behaviour Guidelines for Kids Aged 0-4

Travis’ Note: This morning the Canadian Society for Exercise Physiology released the first official national guidelines for sedentary behaviour and physical activity for pre-school aged children (0-4 years old).  Below we have a post by one of the authors of the new guidelines papers, Allana Leblanc (more on Allana can be found at the bottom of the post).  This post describes the physical activity guidelines – for a similar post outlining the sedentary behaviour guidelines please visit the Sedentary Behaviour Research Network.

The full text of the guidelines papers can be accessed for free via the Applied Physiology, Nutrition and Metabolism website (the sedentary behaviour paper is here, while the physical activity paper is here).  Additional information can also be found on the CSEP website at www.csep.ca/guidelines.

Background

Until recently, only one set of physical activity guidelines was available for children under the age of 5 years (National Association for Sport and Physical Education, 2009). These guidelines were useful recommendations for parents and caregivers with advice on healthy living, but were informed largely on expert consensus and not by the rigor of a systematic review.  Last year, Australia and the United Kingdom (UK) were the first to release evidence-based guidelines and recommend that preschoolers be physically active for at least 180 minutes per day (Department of Health and Ageing, Australia 2011; Start Active, Stay Active, United Kingdom, 2011). The full guidelines can be found here and here. However, a systematic review was still not publicly available to inform the development Canadian guidelines for this age group.

New Study: Ottawa Participants Needed

Just a quick note to let people know about a study taking place in the Ottawa region that may be of interest to anyone with kids aged 8-10.

The study is looking at “what children know and  like about physical activity, with the intention of gaining a deeper understanding of how to help more children engage in healthy and active lifestyles”.  The study takes about 3 hours total, which is spread out over 2 visits.

I have embedded the study recruitment pdf below (email subscribers can view the pdf by clicking on the title of this post), feel free to look it over or send it around to anyone who may be interested.  To get involved with the study, contact research assistant Mike Borghese at mborghese [at] cheo [dot] on [dot] ca or 613-737-7600, extension 4191.

The health-impact of juice is a contentious issue. Yes, it’s full of vitamins and minerals. But it’s also full of sugar.  How much sugar?  The below graph compares the calories and sugar content in a 12-ounce can of Coca-Cola, Pepsi, and Tropicana Orange Juice.  I’ve hidden the names.  Which one is the “healthy” orange juice?
