Mainstream Medicine Is Starting To Wake Up

November 14th, 2008

NOT a self portrait

Yesterday, media outlets around the world ( here, here and here) discussed a new scientific study, published in the New England Journal of Medicine,  which reaffirmed the notion that a large waist can almost double your risk of premature death.

This shouldn’t come as news to anyone who takes an active interest in their health.

Us health nuts have known for years that visceral fat is a killer.

Because of this, I usually just skim these articles to make sure that I am not missing any new breakthroughs.

Surprisingly, in this case, I did find something interesting.

But it wasn’t the research.

It was the response to the research.

I noticed two things:

  1. The Main Stream Media can be pretty stupid, and
  2. Doctors have drastically improved their understanding of how our lifestyle (physical activity, nutrition, thoughts and feelings) impacts our health

So, why do I think that the MSM is stupid?

.

To explain this, I need to tell you a little story.

Yesterday afternoon, a client of mine asked me if I had heard about this new study which claimed that having love handles doubled your risk of premature death.

Love handles?

I told him that he was be mistaken.

Belly fat or visceral fat is bad news.

But love handles?

love-handles-vs-visceral-fat

Love handles may not look very sexy, but they aren’t a killer.

But he was pretty adamant and pointed me to this BBC headline:

Love handles’ raise death risk

Whoops, the BBC screwed up.

The study looks at waist circumference and visceral fat, not love handles.

Love handles, in colloquial or slang speech, are a layer of fat that is deposited around a person’s midsection, especially visible on the sides over the abdominal external oblique muscle. They are called “love handles” because they provide a soft place to rest one’s hand while one’s arm is around a person, or perhaps because they can serve as places to hold on while copulating.

So, before anyone else starts thinking that their love handles are out to get them:

Love Handles: Squishy / Not a Killer

Visceral Fat: Less squishy / Big Time Health Risk

Interesting Observation # 2

Doctors have drastically improved their understanding of how our lifestyle (physical activity, nutrition, thoughts and feelings) impacts our health.

Just check out this video.

What I want you to notice is the doctor’s closing statement.

As he discusses treatment options for patients with a large waist (caused by visceral fat), he says:

“We can ask them to consider exercising more, reducing their carbohydrate intake, taking more fruit and vegetables in their diet, and by that way, we can help them reduce the risk and live longer and happier.”

He doesn’t say:

He says:

And considering that fruits and vegetables are carbohydrates, I think it’s fair to assume that the good doctor is telling us to reduce our consumptions of GRAINS.

Tell me it’s not true.

Eat less bread, corn, pasta and rice…how will I ever survive?

Wii Fit – A Workout for the Fattest Generation

June 19th, 2008

Being a personal trainer, I can’t begin to tell you how many times I have been asked about Nintendo’s Wii Fit.

Is it a good workout?

Will it help me lose fat?

Will I be sucked into the Wii Fit like Jeff Bridges in the movie Tron?

My answers:

It depends

Probably not

Highly unlikely…I hope

What is Wii Fit?

For those readers without children, the Wii Fit is a video game developed by Nintendo for the Wii console. The Wii Fit is unique in that it uses the Wii controller and the Wii Balance Board to enable the user to play a variety of “exercise” games.

In an attempt to market this product as a quasi health device, the Wii Fit calculates your BMI and after a few balance and reaction tests, assigns you a Wii Fit Age.

The goal of the Wii Fit is that by exercising with the Wii Fit, you will be able to lower your BMI and Wii Fit Age.

Is the Wii Fit a good workout?

As I mentioned above, it depends.

If you are even moderately physically fit, the Wii Fit is a waste of time.

In an article published in the National Post, the Wii Fit was tested in the exercise physiology lab at McGill University. Researcher Tania Taivassalo put the Wii Fit through it’s paces to see what sort of workout you can get with it.

The researchers tested the Wii Fit running game and the hula hoop game.

“According to Jean-Philippe Marchand, a kinesiology master’s student who tested the product in the lab, both the running and hula hoop game required the testers to work out at the equivalent of 60% of maximum aerobic power for children. These results classify the games as light physical activity with the potential to improve fitness among those new to exercise, but with little potential to do the same among the fit population”

Even worse than the low level of intensity was the fact that both games offer only short bursts of activity (under five minutes).

Low intensity plus short duration does not equal Olympic marathon champion.

The researchers’ final word on the Wii Fit: “It is definitely meant for sedentary people or for kids to have fun while exercising — as opposed to sitting and moving their thumbs only.”

So, if you, or someone you love is a video game junkie and really, really, really needs to get in shape, the Wii Fit may be a good place to start.

It’s not too intense for a beginner, and it addresses most of the aspects of physical fitness:

Muscular strength, aerobic energy system training, balance and co-ordination.

Will it help me lose fat?

Without changing your eating habits, it is very unlikely that you will lose much body fat with your Wii Fit workout. Period. Sorry.

So, should I buy the Wii Fit?

Unless you are very desperate, I would hold off on buying the Wii Fit.

While it is incredibly popular right now, I have a strong feeling that in a few months, there will be quite a few gently used Wii Fits being offered for sale on Ebay.

Canada: A Nation of Short, Fat Liars

May 15th, 2008

According to Statistics Canada, Canadians are not as tall or thin as they think say they are.

This has caused Stats Can much consternation.

The data that Stats Can collects through it’s Canadian Community Health Survey and the National Population Health Survey rely on Canadians to provide their height and weight.

In 2005, 16% of Canadians were classified as obese; according to their self reported info.

But according to actual measurements, 8% of Canadians are not only fat, but big fat liars to boot.

Oh My God!

What could happen next?

Do you think Canadians lie about their age?

Their income?

Their penis size?

The Horror…..

BMI effectiveness questioned

April 11th, 2008

A study conducted by researchers at the Mayo Clinic says that excess body-fat is associated with early signals of heart disease, EVEN in people whose BMI is considered normal.

Their findings, presented at the American College of Cardiology’s Annual Scientific Session, put into question the effectiveness of the BMI as the primary measure of obesity.

It is amazing that it has taken this long.

The main limitation of this measure of obesity is not the BMI itself, but in it’s implementation. The medical community made a mistake by relying on a ‘one size fits all’ tool like the BMI. Obesity is not a ‘one size fits all’ problem.

The BMI index was meant to be used as “a simple means of classifying sedentary (physically inactive) individuals with an average body composition”.

The key word is average. Not tall people. Not short people. Not muscular people. Not “big boned” people.

AVERAGE people.

I have been helping people eliminate their body-fat and transform their bodies for over 15 years, and I have never had a client who was an AVERAGE person. There is no ‘one size fits all’.

Current research shows that obesity has a very strong genetic component. Like most medical conditions, having a genetic propensity towards obesity does not mean that you will be fat. The lifestyle that you choose to live will determine whether or not you fulfill your genetic predisposition.

Instead of using a BMI, I track my clients’ progress with individualized tools like circumference measurements or calipers or electrical impedance scales.

Note – I was made aware of this study by an article available at this blog. Take a look.
