Contributors to the Pediatric Obesity Epidemic Part 5: Risk Factors I Missed

by Travis Saunders, MSc in Obesity Panacea

Today we will look at other potential contributors to the pediatric obesity epidemic which I didn’t include in my paper. There are a few reasons for that – some risk factors are ones that I just felt didn’t have much evidence behind them, others were similar to ones that were included, and some just didn’t fit within the space constraints (since this paper was originally written for my comprehensive exams, it was limited to 15 pages)....

In Part 1 we examined the impact of changes in physical activity and sedentary behaviour, in Part 2 we looked at changes in food intake, and in Part 3 we looked at sleep, breastfeeding, maternal age and pollution. Today we look at the evidence (or lack thereof) linking adult obesity with the pediatric obesity epidemic, then examine the relative contributions of all of the risk factors we’ve discussed so far....

Xocai and the Chocolate Weight Loss Diet - Where's the Evidence?

by Travis Saunders, MSc in Obesity Panacea

If you spend any time following the "super" foods that are currently promoted on websites and daytime talk shows, you will certainly have heard about the "miracles" of dark chocolate, one of the super-est of all the super foods. If the Super Foods were the Super Friends, chocolate would probably be Batman (second only to Super Man, a role currently filled by Acai Berry).... Read more »

Sedentary Physiology Part 5 – Future Directions

by Travis Saunders, MSc, CEP in Obesity Panacea

Image by kaibara87
Welcome to our 5-part series delving into the fascinating research being performed in the emerging field of sedentary physiology.  In Part 1 we discussed the basics of sedentary physiology, in Part 2 and Part 3 we looked at the association of sedentary time with both death and disease, and in Part 4 we looked at the mechanisms underlying these relationships.  Today we will look at where future work in the field of sedentary physiology is heading.
Given the research that we........ Read more »

The Science of Starvation: How long can humans survive without food or water?

by Peter Janiszewski, Ph.D. in Obesity Panacea

Rita Chretien, a Canadian woman survived being stranded inside a vehicle in Nevada for 48 days, by eating only some trail mix and candy, and drinking water from a stream.  Apparently, she and her husband were following their GPS instructions on their way to Las Vegas from British Columbia when they took a rural road that essentially turns to a bog in the winter months. Their van eventually got stuck in the mud in the middle of nowhere, and they both waited for help for 3 days without sighting a........ Read more »

Turn down your thermostat to lose weight, suggests new study! (Dripping with sarcasm)

by Peter Janiszewski, Ph.D. in Obesity Panacea

So now that I’ve got your attention, let me tell you off the bat that making your home cold is not the most viable weight-loss strategy  -  despite what the headlines might suggest.
A recent study was published in the International Journal of Obesity which looked at a number of uncommonly explored potential contributors to obesity, including sleep restriction, house temperature, television watching, consumption of restaurant meals , use of air conditioning and use of antidepressant/antipsych........

Does sexual intercourse affect athletic performance?

by Peter Janiszewski, Ph.D. in Obesity Panacea

A commonly held belief among many athletes and coaches (particularly male ones) is that sexual intercourse the evening before a competition spells disaster on the big day. Thus, many high-level athletes practice abstinence prior to competition. Muhammad Ali was an outspoken proponent of this rule, as was Marv Levy, head coach of the Buffalo Bills, who separated his athletes from their partners leading up to the SuperBowl.

Sneezing your way to a big belly: Do allergy medications make you fat?

by Peter Janiszewski, Ph.D. in Obesity Panacea

“Achoo!!”
Some folks have seasonal allergies.
But if you’re like me, battling your allergies is a year-round affair.
Some days are certainly better than others, but overall, I have been a chronic user of anti-histamines since my teens. Cleratin, Reactine, Aerius, and Life Brand versions thereof have all at one point or another helped me breathe.
So you may imagine my concern when I came across a recent paper published in the journal Obesity discussing a possible link between the us........ Read more »

How much salt is in your fast food?

by Peter Janiszewski, Ph.D. in Obesity Panacea

Way too much, according to a study by Johnson and colleagues, published in the Archives of Internal Medicine.
Personally, I love salty foods. While I have never been too fond of sweet things (chocolate, candy, etc.), just a few years ago I could have easily gone through a bag of chips or pretzels in one sitting. Just writing about that crunchy/salty goodness makes my mouth water.
However, since hypertension runs in my family, I have recently made a concerted effort to limit my sodium intake R........ Read more »

How inactive are today’s kids?

by Peter Janiszewski, Ph.D. in Obesity Panacea

I was hoping to not begin this post with the following phrase, but its useless fighting the urge. I have reached an age at which I believe I am now entitled to do so.
Back in my day, when I was still in elementary school, I don’t think my parents or those of my friends ever had to worry about us being physically inactive.
Sure we had Nintendo, and Super Nintendo had just come out, but really how many hours could one spend with Duck Hunt?
At the same time, it feels like people were generall........ Read more »

What Hurts Fitness More: 30 Years of Aging or 3 Weeks of Bed Rest?

by Travis Saunders, MSc, CEP in Obesity Panacea

I recently came across a very interesting study published in Circulation in 2001. In it, authors Darren McGuire and colleagues perform the 30-year follow-up on a group of 5 men who had taken part in the Dallas Bed Rest and Training Study (DBRTS). The DBRTS took place in 1966, when all 5 men were healthy 20 year-olds. They were assessed extensively at 3 different time points: baseline, following 3 months of bed rest, and following 8 weeks of physical training. In 1996 these same 5 men were as........ Read more »

Liposuction does not permanently remove fat

by Peter Janiszewski, Ph.D. in Obesity Panacea

Due to the increasing obsession with quick solutions to excess fat mass, liposuction has become one of the most popular cosmetic procedures.
And as far as simply removing large volumes of subcutaneous fat from one’s body, it just may be the most effective method – certainly, far superior to diet/exercise or bariatric surgery.
But there are a few catches.
As I have previously discussed, in contrast to losing weight via lifestyle modification or bariatric surgery, liposuction does not make an ........ Read more »

Human Chorionic Gonadotropin (HCG) for Fat Loss: "Fallacy and Hazard"

by Travis Saunders, MSc in Obesity Panacea

One of the great things about this site is that people often bring products or research to our attention that we otherwise might have missed. This occurred yesterday in the comments section of Peter's recent post on Acai berry scams, when one of our readers brought up the use of Human Chorionic Gonadotropin (HCG) in the treatment of obesity. The website that we were provided smacks of weight loss gimmickry - notably the promise of an obesity "cure" and "near 100% ........ Read more »

Exercise and Body Weight

by Travis Saunders, MSc in Obesity Panacea




Image by atomicjeep


I came across a very interesting article in the Ottawa Citizen this weekend, unpleasantly titled "For Canada's obese, exercise alone isn't going to cut it". The crux of the article is this - exercise will not help you lose weight. Every few months it seems that this issue pops up, including a cover article in TIME magazine last year, which Peter has previously dissected. This is a complicated issue, and given the sensational title, I wasn't expecting much from the Cit........ Read more »

Increased Physical Activity Prevents the Accumulation of Abdominal Fat

by Travis Saunders, MSc in Obesity Panacea

One of the most interesting things about exercise is that it results in important health improvements even in the absence of weight loss. For example, just a single session of exercise can result in improved insulin sensitivity, increased levels of HDL cholesterol (aka the "good" cholesterol) and reductions in plasma triglyceride levels - all tremendously important markers of disease risk. In addition to these metabolic changes, new research by our friend and former labmate Lance Dav........ Read more »

Physical activity protects our body from cognitive stress

by Peter Janiszewski, Ph.D. in Obesity Panacea

There are few of us who can honestly say they are not stressed out at least some of the time. Too much to do, not enough time, looming deadlines, financial concerns, health problems, etc. can all cause us to feel on edge.
Your heart rate and blood pressure soar, you start perspiring, sleeping becomes a challenge, you’re irritable, and so on.
As you might have imagined, chronic psychological stress negatively impacts on your physical health, increasing the chances of countless chronic diseases......... Read more »

Canadian Health Authorities Release New Physical Activity Recommendations

by Travis Saunders, MSc in Obesity Panacea

Last week ParticipACTION and the Canadian Society for Exercise Physiology (CSEP) released recommendations for updated Canadian Physical Activity Guidelines. The previous guidelines were released between 1998 and 2002, and although they were based on the best research available at the time, from what I understand there simply wasn't a tremendous amount of evidence to draw on in some situations. Since then there have been a number of advances in physical activity research, allowing for the........ Read more »
