Obesity Epidemic A Sign of Prosperity

Over the last several posts I have discussed a few aspects of obesity that I think are important in understanding the condition.  There is no doubt that obesity is a multi-factorial issue in adults--I've always contended that.  But I do not feel that way when it comes to kids, because children often do not have the same mental factors, which I believe play such a strong role in chronic obesity (the factor most involved in the I-just-can't-seem-to-lose-weight-no-matter-what-I try-syndrome).  More on this in a future post.

But we already defined obesity--a medical condition in which excess body fat has accumulated to the extent that it may have an adverse effect on health, leading to reduced life expectancy and/or increased health problems--so the question should now be: How has obesity become epidemic?  How have so many people gained weight to such degree as to be detrimental to their health?  The numbers today are harrowing--in the U.S. no state has a prevalence of obesity less than 20%, with some states having 30% or more of their population obese.

This is a fairly new phenomenon, as the numbers in the U.S. have gone through their most dramatic increase only over the last twenty years.  This is one reason I do not buy into the genetic or hormonal-cause theories.  Gene pools don't change that quickly, especially not with regard to a trait that has neither survival nor reproductive advantages.

One major benefit we are experiencing as a result of the current obesity epidemic is that we have learned quite a bit about human physiology, particularly the changes in autonomic function.  What is particularly interesting for me is to see the body's response to an extreme change in condition--an excess weight gain.  It shows, once again, the incredible intelligence of the human body.  The body responds to to a perceived stress in a very predictable way, it tries to reestablish balance, and it does so through the autonomic nervous system (ANS).

These observations have some in the field excited that they have now found the real underlying cause of obesity.  ANS changes and their associated hormonal imbalances are not the cause of obesity.  Emotional or economic stressors are not the cause of obesity.  While these issues are likely factors in the long-term maintenance of obesity, the reason why "weight stays relatively constant," they are not in and of themselves what causes obesity.  Taking in more energy than what is used is the primary cause of obesity.  This phenomenon is predominantly due to one or more of the following factors: 

• Eating more than is needed (we've all done this at one time or another, so it shouldn't be too hard to conceptualize how it could happen repeatedly, leading to a form of conditioning)
• Eating nutritionally-poor foods (more than occasionally)
• Chronic inactivity (which includes constantly challenging oneself)

Yes, hormonal issues like hypothyroidism can cause weight gain, so can medication side-effects, and genetics probably leaves some people more susceptible than others.  But these factors are not responsible for 20-30% obesity rates in the U.S.  No way.

So, once again, how has obesity become epidemic in the U.S. and other western societies?  As far as I can see, obesity is a consequence of prosperity.  When food is abundant, when we do not have to grow, hunt, trap or kill our own food sources, when high-energy foods (not in vibrancy, but calories: think pizza) is just a phone call away, 24-7, what do you think is going to happen?  Poor nations don't have obesity epidemics.  Oh they may have obese people...but not an epidemic.  Think about it.  Obesity is mostly a condition of abundance.

Obesity is also a consequence of population growth.  The more mouths we have to feed in rich, industrialized nations, the more we have to manufacture foods that will preserve long-term storage, transport and shelf-life.  Simple as this: To feed millions of people, foods are tweaked to prevent their perishing, and as a result we get chemical- and preservative-laden foodstuff, as well as the now prevalent, yet highly controversial, genetically-modified organisms (GMOs).  Ingesting these food-like substances, as I like to call them, in large quantities or over long periods can lead to excessive weight gain.

Sorry to foolish skeptic, but sodas do cause weight gain, plain and simple. It's no surprise to me that obesity has run concurrently with both American power and prosperity in the world, but also with the explosion of the food industry, particularly processed  foods (and junk food, and fast food, and soda consumption...)

As I've hinted in a previous post, I also believe a very strong mental component is involved in the obesity epidemic.  No doubt the psychological makeup of society is contributing to this massive inflation.  The coddling of the obese by searching for an it's-something-outside-of-you cause is no small factor in making obesity an epidemic.  Next post, I will discuss weight loss and what I think is a better approach to decreasing the prevalence of obesity in modern society.

Unhealthy Habits Age You by 12 Years

As important as practicing healthy habits is, discontinuing (or better yet never starting) poor health habits can add years to your life--twelve to be exact; this according to the findings of a recent study. Let's see, twelve years ago I was...DANG that's a long time! Check it:

The study tracked nearly 5,000 British adults for 20 years, and looked at the following four bad health habits:

• smoking
• drinking too much
• inactivity
• poor diet

Researchers found that people partaking in these habits had a substantially increased risk of death, and they seemed 12 years older than people in the healthiest group. Doh!

Of the research subjects having all four habits (314 people), 29% died through the study period. The subjects having none of the habits (394), only 8% had died. The people involved in the study were adults aged 18 and older, but 44 years old on average. The most common cause of death among subjects was heart disease and cancer, both caused by the unhealthy habits studied.

The healthiest group included never-smokers and those who had quit; teetotalers, women who had fewer than two drinks daily and men who had fewer than three; those who got at least two hours of physical activity weekly; and those who ate fruits and vegetables at least three times per day.

"You don't need to be extreme" to be in the healthy category, said lead researcher Elisabeth Kvaavik of the University of Oslo. "These behaviors add up, so together it's quite good. It should be possible for most people to manage to do it."

Tis true. It is one of the major premises in my book, The Six Keys to Optimal Health. Healthy habits are cumulative. Start slowly and add habits one by one. For example, start with bodywork, like chiropractic care, and get out of pain. Once pain starts to subside, start exercising. Cut out sodas next. Then start eating more fruits and vegetables, and so on. It doesn't have to all be done at once. Pick up a few healthy habits, then go for the more challenging ones, like quitting smoking or drinking or mainlining speed. Having a foundation of a handful of healthy habits will get you through a lot easier than trying to kick a habit cold turkey with nothing to fill the void.

By reducing faulty health habits you could add twelve years to your life--no small amount once you start getting up there. Add to that a few healthy habits and woo-boy you might even tack on another twelve. Think of that. What will you do with the time?

Couch Potatoes Gone Global

It's not just American children sitting on their rumps these days--children all over the world are chronically inactive. So says a recent study that looked at over 70,000 teens in 34 nations.

Children from Argentina to Zambia are not getting enough exercise, and are spending three or more hours a day watching TV or playing on computers. Whether a country was rich or poor made no difference to the inactivity of their youth; dismal news on the state of modern culture. No knock on technology, but parents of all nationalities need to limit the amount of boob tube and web surfing their children do, and push them more toward physical activity.

The study, published in The Journal of Pediatrics, looking at 72,845 schoolchildren aged 13 to 15 from North and South America, Asia, Europe, and the Middle East. The children were surveyed between 2003 and 2007. Children that spent three or more hours a day watching TV, playing on computers or chatting with friends--outside of school time or doing homework--were considered sedentary. Only 25% of boys and 15% of girls worldwide were getting enough exercise. Girls were overall less active than boys in every country except Zambia.

Some of the numbers:

• Uruguay had the highest percentage of active boys, at 42%, while Zambia had the lowest, at 8%.
• Girls from India were the most active, with 37% meeting exercise recommendations, while girls from Egypt were the least active, with just 4% getting adequate exercise.
• Children in Myanmar were the least sedentary, with 13% of boys and 8% of girls classified as sedentary.
  
• The most sedentary nations were St. Lucia and the Cayman Islands, with 58% of boys and 64% of girls spending at least three hours a day in sedentary activities.

Once again, parents would be wise to get the kids kicking, playing and using their bodies. Technology is a great thing; but with every great thing comes a downside, and in this case it's the risk of becoming couch potatoes. Inactivity and the associated risk of childhood obesity is no longer an American phenomenon--it's gone global. Time to change.
