WHY SUGAR MAKES YOU FAT
by Ben Greenfield
Look at how many grams of sugar are in what you're eating (on the nutritional label). Now divide that number by 4. That's how many teaspoons of pure sugar you're consuming. Kinda scary, huh? Sugar makes you fat and fat-free food isn't really free of fat. I've said it before in multiple articles, but occasionally, I've had someone lean over my desk and say "How in the heck does sugar make you fat if there's no fat in it?". This article will answer that puzzler, and provide you with some helpful suggestions to achieve not only weight loss success, but improved body health.
First, let's make some qualifications. Sugar isn't inherently evil.
Your body
uses sugar to survive, and burns sugar to provide you with the energy
necessary
for life. Many truly healthy foods are actually broken down to sugar in
the body
- through the conversion of long and complex sugars called
polysaccharides into
short and simple sugars called monosaccharides, such as glucose. In
additions to
the breakdown products of fat and protein, glucose is a great energy
source for
your body.
However, there are two ways that sugar can sabotage your body and
cause fat
storage. Excess glucose is the first problem, and it involves a very
simple
concept. Anytime you have filled your body with more fuel than it
actually needs
(and this is very easy to do when eating foods with high sugar content),
your
liver's sugar storage capacity is exceeded. When the liver is maximally
full,
the excess sugar is converted by the liver into fatty acids (that's
right -
fat!) and returned to the bloodstream, where is taken throughout your
body and
stored (that's right - as fat!) wherever you tend to store adipose fat
cells,
including, but not limited to, the popular regions of the stomach, hips,
butt,
and breasts.
As an unfortunate bonus, once these regions are full of adipose
tissue, the
fatty acids begin to spill over into your organs, like the heart, liver,
and
kidneys. This reduces organ ability, raises blood pressure, decreases
metabolism, and weakens the immune system.
Not good!
Excess insulin is the second problem. Insulin is a major hormone in
the body,
and is released in high levels anytime you ingest what would be
considered a
"simple" carbohydrate, which would include, but not be limited to: fruit
juice,
white bread, most "wheat" bread (basically white bread with a little
extra
fiber), white rice, baked white potato, bagels, croissants, pretzels,
graham
crackers, vanilla wafers, waffles, corn chips, cornflakes, cake, jelly
beans,
sugary drinks, Gatorade, beer, and anything that has high fructose corn
syrup on
the nutritional label.
Two actions occur when the insulin levels are spiked. First, the
body's fat
burning process is shut down so that the sugar that has just been
ingested can
be immediately used for energy. Then, insulin takes all that sugar and
puts it
into your muscles. Well, not quite! Actually, most of us, except those
random
Ironman triathletes and 8000-calories-per-day exercisers, walk around
with
fairly full energy stores in the muscles. As soon as the muscles energy
stores
are full, the excess sugars are converted to fat and, just like the
fatty acids
released from the liver, stored as adipose tissue on our waistline.
But that's not all. After the blood sugar has been reduced by going
into the
muscles or being converted to fat in the liver, the feedback mechanism
that
tells the body to stop producing insulin is slightly delayed, so blood
sugar
levels fall even lower, below normal measurements. This causes 1) an
immediate
increase in appetite, which is usually remedied by eating more food; 2)
the
production of a stress hormone called cortisol. Cortisol triggers the
release of
stored sugar from the liver to bring blood sugar levels back up, which,
combined
with the meal you eat from your appetite increase, begins the entire
"fat
storage, metabolic decrease" process over again.
This process of destabilizing blood sugar levels and sending your
body on a
roller coaster ride can occur throughout an entire day, week, or month.
The
excessive cortisol that accumulates in the body eventually distresses
your
hormonal system and results in other problems, including a further
decrease in
metabolism, obesity, depression, allergies, immune weakness, chronic
fatigue
syndrome and other serious side effects.
So what kind of carbohydrates can you eat to avoid de-stabilizing
blood sugar
levels, constantly sabotaging your weight loss, and spending hundreds of
thousands of dollars in health care as you get older? Here is a list of
carbohydrates do not trigger such a strong insulin response and instead
provide
long-term, stabilized energy: apples, oranges, pears, plums, grapes,
bananas
(not overly ripened), grapefruit, oatmeal, brown rice, whole wheat
spaghetti and
egg fettuccine, whole- wheat pasta, bran cereal, barley, bulgur,
basmati, Kashi
and other whole grains, beans, peas (especially chick and black-eyed),
lentils,
whole corn, sweet potatoes, yams, milk, yogurt (preferably low-fat or
fat-free)
and soy. Stay away from processed and packaged foods as much as
possible,
because they are highly likely to include artificial sweeteners (which
basically
have a similar effect as sugar), as well as simple and refined sugars.
Keep your
eye out for ingredients that include sucrose, maltose, dextrose,
fructose,
galactose, glucose, arabinose, ribose, xylose, deoxyribose, lactose, and
other
fake names for sugars. Even "healthy" juice and many health food
products will
need to be avoided if they contain high levels of sugar.

elite@pacificfit.net, and I'll give you some suggestions on how a
personal
trainer can help you with your nutrition. My new book, Shape21, includes
21 days
of nutritional intake that completely stabilizes blood sugar levels,
which, when
combined with the perfect exercise program that I've detailed in the
book,
leaves you with a lean, athletic body. You can check it out at my
website, www.pacificfit.net, or at a gym near you. E-mail elite@pacificfit.net for more information.
