Can You Be Thin and Fat?
By Steve Edwards and Denis Faye
Two stories about body fat have hit the wires recently and both deserve
a deeper look than the headlines may indicate. The first is about a
condition referred to as "skinny fat," which means that though
your body mass index (BMI) may be normal, you're really out of shape. The
second is about a book called Rethinking Thin: The New Science of
Weight Loss—and the Myths and Realities of Dieting, which basically
lays the blame of obesity on your family history. So read on and we'll
save you some time by getting to the skinny on being skinny.
The inside scoop on inside fat
It turns out that those "lucky" people you know who eat junk
food all day and still keep their figures may not be as lucky as you
think. A study from London's Imperial College shows that they may appear
skinny to the naked eye, but in truth, they're fat on the inside, which
could lead to a rash of health problems.
Since 1994, Dr. Jimmy Bell and his team at the college have done MRIs
on nearly 800 people, creating "fat maps" that show where they
store fat. As it turns out, people who don't maintain their weight with a
combination of exercise and diet keep huge fat deposits around their
internal organs.
The exact consequences of this inner blubber aren't clear yet, but it
doesn't look good. We all have some of it, which tends to increase with
age in order to "protect" our organs. But scientists theorize
that excessive inner fat can confuse the body's communication systems,
leading to heart disease, insulin resistance, or type 2 diabetes.
What is clear is that fat, active people have a much lower mortality
rate than the skinny and sedentary. This means that, as far as your health
is concerned, a fitness test is a much better indicator than a scale or
what size dress you fit into. As Bell explained to the Associated Press,
"the whole concept of being fat needs to be redefined."
I blame my parents!
And while we're talking about redefining the concept of fat, could it
be your parents' fault that you're obese? That seems to be the theory of a
new book by Gina Kolata titled Rethinking Thin: The New Science of
Weight Loss—and the Myths and Realities of Dieting. The book
references a handful of studies that show that those who are genetically
predetermined to be obese have greater rates of obesity than those who
aren't, and that diet and exercise can't change that fact. It cites some
good science and interesting studies—especially those involving
separated twins—to make its case. The book also cites some studies where
those who had lost a lot of weight all seemed to gain it back. It's
compelling reading, for sure, even for people like us who know full well
from firsthand experience that a piece of the puzzle was being omitted.
But before we could say "Hey, wait a minute... ," an interesting
thing happened. The New York Times ran an excerpt from the book a
few weeks back and opened up a forum for Kolata herself to field questions
on the article. The results of this forum may make you want to think twice
about purchasing Kolata's book or, at least, to read it with a skeptical
eye and an open mind.
In the book, Kolata's premise is that genetics play a larger role in
determining body shape and mass than diet and exercise possibly can. And
while she provides scientific examples, she really hasn't covered the
entire process in a thorough manner. In the forum, she began refuting
feedback with science, but as the onslaught of responses became more
technical and from varying points of view, her responses reverted to her
own anecdotal evidence. For instance, she used the fact that her son only
lost three pounds when he trained for a marathon as a reason exercise
can't make someone thin. Faced with many individuals who had succeeded in
greatly altering their body masses or inherited fitness states, her tone
ranged from first sounding incredulous to just plain being shocked at the
results people had gotten. Finally, under a mounting wave of pressure from
contradictory opinions, she stopped answering altogether.
This is hardly shocking news to the folks at Beachbody. If it were
true, we wouldn't be in business. Kolata states that "very few people
lose substantial amounts of weight and keep it off for good," but we
have thousands of examples that have proven her wrong. In fact, if we were
to scour the Message Boards, we'd be hard pressed to find any
scenario—injury, sickness, genetic obesity—that our clients have not
conquered. While it's true that you can't change your body type, your
natural athletic ability, or the genes you were born with, we have yet to
find people who can't be made fitter and healthier and who can't change
the way they look, with the proper prescription of diet and exercise. Our
answer is to let 'em manufacture excuse science all they want, but until
our Success
Story pool stops growing, nothing is going to "prove" our
methods don't work.
