New data published in JAMA Internal Medicine paints a dire picture of health in the US based on the increasing prevalence of overweight and obesity.1
In 2007, a research team at Johns Hopkins University predicted that if
current trends in weight gain continued, 75 percent of US adults would
be overweight by 2015.
Here we are in the year 2015, and researchers used data from the
National Health and Nutrition Examination Survey (NHANES) gathered
between 2007 and 2012. The data, which is based on more than 15,000
adults, revealed the John Hopkins predictions were spot on.
Today, about 75 percent of US men and 67 percent of US women are
either overweight or obese. This has risen significantly from figures
gathered between 1988 and 1994, when “just” 63 percent of men and 55
percent of US women were overweight or obese.2
Fewer Than One-Third of Americans Are at a Healthy Weight
The NHANES data revealed that about 35 percent of men and 37 percent
of women are obese, while another 40 percent of men and 30 percent of
women are overweight.
This means less than one-third of US
adults are at a healthy weight. Lin Yang, a postdoctoral research
associate at Washington University School of Medicine in St. Louis, told
Medicine Net:3
"Obesity is not getting better. It's getting worse, and it's really scary. It's not looking pretty…
This
generation of Americans is the first that will have a shorter life
expectancy than the previous generation, and obesity is one of the
biggest contributors to this shortened life expectancy because it is
driving a lot of chronic health conditions.”
The findings are based on body mass index (BMI), which divides a person's weight by the square of his height.
When
you have your height and weight recorded at your doctor's office, for
instance, it will give him or her an automatic calculation of your BMI,
classifying you as underweight if your BMI is below 18.5, normal if it's
18.5-24.9, overweight if it's 25-29.9, and obese if it's 30 or over.
BMI is a flawed measurement tool, in part because it uses
weight as a measure of risk, when it is actually a high percentage of
body fat that increases your disease risk.
BMI also tells you nothing about where fat is located in your body,
and the location of the fat, particularly if it's around your stomach
(visceral fat), is more important than the absolute amount of fat when
it comes to measuring certain health risks.
In 2012, researchers compared BMI measurements to body fat percentage
(using a DEXA scan, which is a FAR more accurate method to assess body
fat percentage) among 1,400 people.4
For women, about half of those who were not classified as obese according to BMI were considered obese according to body fat.
Among men, one-quarter of those not identified as obese by BMI were
found to be obese by body-fat measures. In all, nearly 40 percent of
participants whose BMI classified them as overweight were actually obese
when their percentage of body fat was taken into account.
What this means is that using BMI as a measurement tool may actually be underestimating the obesity epidemic. As noted in PLOS One:5
“…BMI presents as an inaccurate obesity classification method that
underestimates the epidemic and contributes to failed treatment.”
Average US Woman Now Weighs as Much as a Man in 1960s
Recent data from the US Centers for Disease Control and Prevention
(CDC) similarly shows that Americans have been packing on extra pounds
since the ‘60s. The average US woman now weighs just over 166 pounds,
which is what the average US man weighed in the 1960s. In 1960, the
average woman weighted 140 pounds.
Men, meanwhile, have gained about 30 pounds over the last several
decades, increasing in weight from 166 pounds in the 1960s to an average
of over 195 pounds today.6
While some of the difference is due to changes in height – both men
and women have grown about one inch since the ‘60s – this isn’t enough
to account for the entire weight gain, which amounts to an overall
increase of nearly 19 percent in women and 18 percent in men since 1960.
Americans now represent the world’s third-heaviest people, behind
only Tonga and Micronesia, which are both Pacific Island countries.7 As reported by CBS Atlanta:8
“The average U.S. adult is 33 pounds heavier than the average
Frenchman and 70 pounds heavier than the average Bangladeshi citizen. To
compile a ton of total mass, it would require only 12.2 Americans in a
room versus 20 average citizens of Bangladesh.
A 2005 BMC Public Health study revealed that the world’s adult human
beings make up 287 million tons of biomass, but if every country was as
large as the U.S., Earth would be 58 million tons fatter.”
What Is Driving Rising Rates of Overweight and Obesity?
Obesity, and its causes, is complex. Often, it is not simply the result of eating too many calories and not exercising enough.
While
it is part of the equation, environmental and lifestyle factors appear
to play a far more significant role in this trend. Part of the problem
is that many people don’t realize they’re affected by these stealthy
factors and therefore fail to address them. This includes:
- Overuse of antibiotics in food production and medicine
- Growth-enhancing drugs used in food animals
- Endocrine-disrupting chemicals, including pesticides
- Artificial sweeteners
- Aggressive marketing of harmful junk food
Highly processed genetically modified (GM) foods are the primary
culprit, as they’re chockfull of ingredients that both individually and
in combination contribute to metabolic dysfunction and hard-to-control
weight gain.
The 300+ members of the pro-GMO Grocery
Manufacturers Association (GMA) include chemical/pesticide (i.e.
Monsanto), GM (genetically modified) seed, and processed food
industries.
While they claim GM crops are "necessary" to feed a growing population,
they rarely show their actual results of FATTENING the world.
They
make no progress with starvation due to distribution issues, and
instead look for profitable ways to get more people eating the GM diet
staples of corn syrup, trans fats from soybean oil, and sugar, which
together fuel the rising obesity rates around the globe.
The safety of the entire GM “food” production is a boldfaced lie when you look at these primary food crops sickening Americans:
- High fructose corn syrup—one of the primary sources of calories in the American diet—is made from GM corn (Bt corn), registered with the US Environmental Protection Agency (EPA) for producing its own internal pesticide
- Hydrogenated vegetable oils (trans fats) known to cause heart and
cardiovascular disease is made from GM soy that is resistant to
pesticide. This allows it to soak up much more of it than non-GM soy
- Sugar beets are also genetically engineered, ensuring that even
foods sweetened with "regular sugar" fall into a more toxic category,
courtesy of elevated pesticide contamination
Corn syrup, trans fats, and sugar – along with heavily processed
refined grains -- these ingredients are now foundational in the US diet,
and there is virtually no doubt that they are primary contributors to Americans' failing health and rising rates of obesity.
What Are the Health Risks of Obesity?
According to a report by The McKinsey Global Institute, the global
cost of obesity is now $2 trillion annually, which is nearly as much as
the global cost of smoking ($2.1 trillion) and armed violence (including
war and terrorism, which also has a global cost of $2.1 trillion).9
For comparison, alcoholism costs are $1.4 trillion annually, road
accidents cost $700 billion, and unsafe sex costs $300 billion. What’s
more, if current trends continue, the McKinsey report estimates that
nearly half of the world's adult population will be overweight or obese by 2030.
Along with excess body weight comes a wide range of other health problems. In the US, eight obesity-related diseases account for a staggering 75 percent of healthcare costs. These diseases include:
The four diseases in the left column are associated with metabolic
syndrome, which is a common factor in obesity. However, several other
diseases fall within this category as well, which are listed on the
right. And many more could be added to that list. According to the
Surgeon General, in addition to the diseases mentioned above, obesity
increases your risk for asthma, sleep disorders (including sleep apnea),
depression, pregnancy complications, and poor surgical outcomes.11
Last year, a systematic review and meta-analysis that included data from
more than 61,000 people found that obese individuals were more likely
to die sooner or have heart-related problems than people of normal
weight – even if they were otherwise healthy. The researchers concluded:12
"Compared with metabolically healthy normal-weight individuals,
obese persons are at increased risk for adverse long-term outcomes even
in the absence of metabolic abnormalities, suggesting that there is no
healthy pattern of increased weight."
‘No Single Intervention’ Will Solve the Obesity Epidemic
As reported by The McKinsey Global Institute, “existing evidence
indicates that no single intervention is likely to have a significant
overall impact.”13 Instead, they recommended a “systemic, sustained portfolio of initiatives,” which include such options as:
- Reducing default portion sizes
- Changing marketing practices
- Restructuring urban and education environments to facilitate physical activities
- Reformulating food products
- Workplace wellness
Rather than wait for the “perfect proof” of what works, the report
urges experimenting with solutions immediately, especially when the
interventions are low cost and low risk. The changes, according to their
findings, should “rely less on conscious choices by individuals and
more on changes to the environment and societal norms.” This, they say,
is important because education and personal responsibility are not
sufficient on their own to reduce obesity.
This is a stance I can’t completely agree with. Societal changes are
indeed important, but so is personal choice and, absolutely, education
-- spreading the truth about what really works to maintain a healthy
body weight. Starchy, carb-rich, highly processed (and typically
genetically modified) foods, along with being in continuous feast mode,
are primary drivers of the rising obesity and overweight statistics.
Wherever a highly processed food diet becomes the norm, obesity
inevitably follows.
Are You Ready to Reach and Maintain Your Healthy Weight?
Most overweight Americans have some degree of insulin and leptin
resistance. Generally, in order for you to significantly gain weight,
you must first become leptin resistant. Leptin is a hormone that helps
you regulate your appetite. When your leptin levels rise, it signals
your body that you're full so you'll stop eating. However, as you become
increasingly resistant to the effects of leptin, you end up eating
more. Many people who are overweight also have an impairment in their
body's ability to oxidize fat, which leads to a low-energy state.
Dr. Richard Johnson's research clearly shows that refined sugar (in
particular fructose) is exceptionally effective at causing leptin
resistance in animals, and it's very effective at blocking the burning
of fat. If you are insulin or leptin resistant, as long as you keep
eating fructose and grains you're programming your body to create and store fat...
This
is one of the key reasons why, if you are overweight (which means you
are also likely insulin or leptin resistant), it would be prudent for
you to restrict your fructose consumption to about 15 grams of fructose
per day from all sources. Not only will this help you to avoid
additional weight gain, it will also help you to avoid further metabolic
dysfunction.
You may find this fructose chart
helpful in estimating how many grams of fructose you are consuming each
day. Dietary sugar, especially fructose, is a significant "tripper of your fat switch," however, if you are serious about losing weight, you'll need a comprehensive
plan that includes the following. This plan will help most people lose
weight but, also, it will help you to gain metabolic health. So even if
your weight is normal, you can follow this plan to ensure that you're
metabolically healthy as well.
- Eliminate or strictly limit fructose in your diet, and follow the healthy eating program in my comprehensive nutrition plan.
- You can also use intermittent fasting
strategically with this program to greatly boost your body's
fat-burning potential. Intermittent fasting helps reset your body to
use fat as its primary fuel, and mounting evidence confirms that when
your body becomes adapted to burning FAT instead of sugar as its
primary fuel, you dramatically reduce your risk of chronic disease. Exercising in a fasted state (such as first thing in the morning) will bring it up yet another notch.
A simple way to get started with intermittent fasting is to simply
omit breakfast, making lunch the first meal of your day. Alternatively,
stop eating earlier in the day so you have a longer natural fasting
period from early evening until the morning.
- Engage in high-intensity Peak Fitness exercise
to burn fat and increase muscle mass (a natural fat burner). Also,
strive to sit less (much less, such as only three hours a day) and
walk 7,000 to 10,000 steps a day in addition to your regular exercise program.
- Address the emotional component of eating. For this I highly recommend the Emotional Freedom Technique (EFT), which helps eliminate your food cravings naturally.
How to Determine What Your Healthy Weight Is…
As mentioned earlier, BMI is a flawed measurement tool, so branding
yourself as unhealthy or overweight (or vice versa) simply based on your
BMI is not recommended. Your waist-to-hip ratio is a more reliable
indicator of your future disease risk because a higher ratio suggests
you have more visceral fat.
Excess visceral fat—the fat that accumulates around your internal
organs — is far more hazardous to your health than subcutaneous fat (the
more noticeable fat found just under your skin) – a measure that BMI
tells you nothing about.
The danger of visceral fat is related to the release of proteins and
hormones that can cause inflammation, which in turn can damage arteries
and enter your liver, affecting how your body breaks down sugars and
fats. To determine your waist-to-hip ratio, get a tape measure and
record your waist and hip circumference. Then divide your waist
circumference by your hip circumference. For a more thorough
demonstration, please review the video above.
| Waist-to-Hip Ratio |
Men |
Women |
| Ideal |
0.8 | 0.7 |
| Low Risk |
<0.95 | <0.8 |
| Moderate Risk |
0.96-0.99 | 0.81 - 0.84 |
| High Risk |
>1.0 | >0.85 |
In addition, your fitness level is also a far better predictor of
mortality than your BMI. One study found that people who rarely
exercised had a 70 percent higher risk of premature death than those who
exercised regularly, independent of their BMI.14
If you want a simple test to gauge your fitness level, try the
abdominal plank test (for a demonstration of how to do a plank, see the
video below). If you can hold an abdominal plank position for at least
two minutes, you're off to a good start. If you cannot, you're likely
lacking in core strength, which is important for overall movement
stability and strength.
