A third of the U.S. population is now overweight, making it just a matter of
time before normal-size people are actually in the minority. Americans have so
ballooned in size, government safety regulators worry that airline seats and
belts
won't
restrain today's men who average 194 pounds and women who average 165
pounds, in a crash.
Not everyone agrees that obesity is always a
health
problem. You can be overweight and still have normal blood pressure, blood
sugar, HDL cholesterol and other metabolic markers if you exercise, say some,
pointing to U.S. Surgeon General Regina Benjamin, who
hiked the Grand Canyon in 2010 despite
her extra poundage.
But others say fitness and exercise will not reverse the health effects of
obesity. The British medical journal
The Lancet recently reported that
rising obesity in the U.K. will cause an
extra
half a million cases of heart disease, 700,000 cases of diabetes and 130,000
of cancer by 2030. And the overweight and obese are 80 percent more likely to
develop dementia writes
Kerry
Trueman on AlterNet.
And there are other obesity "negatives." The obese are less likely to be
employed, earn less than people of normal weight and "have more days of absence
from work, a lower productivity on the job and a greater access to disability
benefits," reports the Paris-based policy group
Organisation for Economic
Co-operation and Development.
Obesity raises Medicare, Medicaid and private insurance costs and affects
national security, writes David Gratzer on
KevinMD.com,
"since thousands of recruits are turned away from military service because of
failed physicals and poor overall health." It also shortens "the lifespan of
millions of decent Americans who deserve better," he writes.
Yet eating too much and exercising too little, considered the root of
obesity, are not the only probable culprits. Here are some other factors that
are often overlooked.
1. Depression and Depression Drugs
Classic depression is characterized by a decrease in appetite, weight loss
and general despondency. But in 1994, "atypical depression" debuted, a subtype
of depression characterized by an
increase in appetite and
weight
gain (as well as
oversensitivity
to rejection by others). Unfortunately, both types of depression are often
treated with popular antidepressants like Prozac, Zoloft, Lexapro and Paxil and
antipsychotics like Seroquel, Zyprexa and Risperdal, all of which can pack on
the pounds.
To keep the weight gain from affecting Pharma sales, the pro-pill site,
WebMD,
tells patients that keeping the pounds off is
their responsibility
since only "healthy eating and exercise help control your weight gain." But it
also counsels if the pill weight gain is "so strong that it simply can't be
offset by any amount of calorie restricting or even exercise," the psychoactive
medication "to help overcome your depression is far more important." To
whom?
2. Artificial Sweeteners
Artificial sweeteners, found in soft drinks, many diet foods and an
astounding number of children's cereals for unclear reasons, may do more harm
than good. While marketed and perceived as helping people avoid calories, they
can have two insidious side effects: because they are sweet they encourage sugar
craving and sugar dependence just like salty foods train people to crave salt,
says research in the
Yale Journal of
Biology and Medicine.
And, because sweetness is "decoupled from caloric content," they fail to
satisfy the sweets reward system and actually further fuel "food-seeking
behavior," wrote the researchers. See: giving hungry dog rubber bone. One
artificial sweetener, Splenda, also has molecular similarities to endocrine
disrupter
pesticides,
say food safety advocates.
3. Antibiotics
Noting that the average child in the U.S. and other developed countries "has
received 10–20 courses of antibiotics by the time he or she is 18 years old,"
microbiologist Martin Blaser published some disturbing suggestions in the
journal
Nature last
year. By killing "good" bacteria with important roles in the body, "Overuse of
antibiotics could be fuelling the dramatic increase in conditions such as
obesity, type 1 diabetes, inflammatory bowel disease, allergies and asthma," he
reports.
Yes, obesity. Mice given low-dose antibiotics that mimic farm use and
high-dose antibiotics that mimic infection treatment in children exhibited
preliminary "changes in body fat and tissue composition," says Blaser. Mice
developed as much as a 40 percent increase in fat and a 300 percent increase in
fat when given a high-fat diet too, extrapolated
Alice
Wessendorf on the research. Denmark researchers found eerie parallels in
humans.
Babies given antibiotics within six months of birth were more likely to be
overweight by age 7.
4. Endocrine Disrupters
Antibiotics are not the only widely used substances that may be associated
with a host of human problems. Chemicals called endocrine disrupters, found in
everything from canned foods and microwave popcorn bags to cosmetics and
carpet-cleaning solutions, are linked to breast cancer, infertility, low sperm
counts, genital deformities, early puberty and diabetes in humans and alarming
mutations in wildlife.
Many are aware of the endocrine disrupter BPA (Bisphenol A)
banned
in baby bottles and sippy cups in Washington state but given a pass by the
FDA
in March. But few realize that similar endocrine disrupters are found in flame
retardants like phthalates and PBDEs, thermal receipts given out at stores and
in "antibacterial" dish detergents and toothpaste, like
Tricoslan
found in Colgate's Total. Endocrine disrupters may also be linked to obesity.
Pregnant women with high levels of PFOA, one disrupter, were three times as
likely to have daughters who grow up to be overweight,
reported
the New York Times' Nicholas Kristof in May.
5. Start 'em Young Marketing
Bad eating is learned young and unfortunately some of the worst messages come
from TV, parents and school. In a
study
in the journal Pediatrics, 4- to 6-year-olds who tasted identical
graham crackers and gummy fruit snacks with and without cartoon characters
"significantly preferred the taste of foods that had popular cartoon characters
on the packaging."
Researchers who studied
500,000
California middle- and high-school students found those with schools near
fast-food outlets were heavier. And
another
study of kids 12 to 19 found
not one child ate a diet meeting all
five of the American Heart Association’s criteria. Even though almost a third of
U.S. children and teens are overweight,
84
percent of parents believe their children are at a healthy weight, say
researchers, which compounds the problem.
6. Hooked on Cookies…and Chips, Pizzas and Ice
Cream
For some overweight people, overeating is an actual addiction. Like
alcoholism, food addicts are "preoccupied with their drug (food). Whether they
are thinking about their next meal, trying to suppress their cravings, planning
their diet, feeling guilty about their last binge [or] hoping to find the
strength to say no to that dessert or second helping," writes Arya M. Sharma
on
KevinMD.com.
Like alcoholics, they dream their troubled relationship to food can
miraculously heal, perhaps if their brain readjusts its "setpoint" or they spend
"an hour in the gym each day," says Sharma. The increase in food addiction might
correlate with the decrease in family meals, indicates some research. Studies by
the
National
Center on Addiction and Substance Abuse reveal that food and other
addictions are less likely to develop in children of families who eat together
three times a week. Who remembers family meals?
7. Lifestyle Factors
There's another habit we learn (or don't learn) while growing up that can
contribute to obesity--a strict bedtime, which few adults or children observe
anymore. After just six nights of getting only four hours sleep, healthy young
volunteers showed signs of prediabetes, reports the
Chicago
Tribune.
Other studies show sleep-deprived adults are more likely to be fat,
regardless of how much they exercise and what they eat. Why? Researchers
hypothesize that sleep deprivation changes levels of the hormone ghrelin (that
tells the brain to eat), leptin (that tells the brain we're full) and the stress
hormone cortisol. There's even another lifestyle contribution to obesity: room
temperature. ABC News reported that
air
conditioning can add weight by sparing the body the need to regulate
temperature, which is a mechanism that burns fat.
8. Government Duplicity
Is the government really helping people to slim down and avoid foods that
pack on pounds and invite the risk of heart disease? High-saturated-fat foods
like cheese? Not according to a
New
York Times expose in 2010. A USDA group with 162 employees called Dairy
Management, mostly funded by farmers, is shamelessly committed to getting people
to
double and triple their cheese intake to replace profits from
falling milk sales.
According to the
Times, Dairy Management has supported Pizza Hut,
Taco Bell, Burger King, Wendy's and Domino’s in "cheesifying" their menu
options, putting dairy farmers' profits before consumer health. "If every pizza
included one more ounce of cheese, we would sell an additional 250 million
pounds of cheese annually,” rhapsodized the Dairy Management chief executive in
a trade publication. Dairy Management received $5.3 million from the USDA during
one year, for an overseas dairy campaign, which almost equals the
total $6.5
million budget of USDA's Center for Nutrition Policy and Promotion. That's
the group that tells people not to eat high fat milk and cheese!
