Hyper-Eating: It’s All in Your Head (& You
Can Get It Out)
Why do Americans report gaining, on average, five pounds between
Thanksgiving and New Years? It’s easy to blame our annual belly
bulge on the abundance of high-calorie food. But David Kessler, MD,
author of The End of Overeating, says that some of us actually
have a brain programmed to “hyper-eat,” and the holidays
send it into overdrive. Here are the basic points in his argument:
■ Sugar, fat and salt make brain chemistry
go wild. All three
activate the brain’s production of dopamine, a neurotransmitter
that focuses human attention. Laboratory studies prove that dopamine
levels rise higher in some people than others when they consume any
of these unhealthy ingredients. And when any two are combined, the
spike is particularly high.
■ Such foods train the brain to stay hungry. They
neurologically arouse the
urge to consume unhealthy foods and, in some people, keep it aroused
too long. For example, soon after a healthy eater starts enjoying
a piece of chocolate cake, the brain’s dopamine production
shuts off. In hyper-eaters, it remains activated so they don’t
begin to feel full. Instead, they must consciously force themselves
to stop eating what they still crave.
■ Not everyone is equally vulnerable.
Ask yourself three questions. Do you lose control around
highly appealing foods? Is it hard for you to realize that you’re
full when you eat them? And do you think about these foods between
meals? The more you identify with the questions, the more programmed
your brain is to overeating.
■ Hyper-eating is not an eating disorder. It
impacts an estimated 70 million Americans and typically begins in
childhood. Here’s
how it works: if you give a 2-year old more calories than she normally
consumes, her body will compel her to eat less later in the day.
But if you feed her sugar, fat and salt frequently throughout the
day for a few years, her brain will begin to lose the ability to “compensate” for
the calorie splurge. And by age 5, she’ll probably be programmed
to overeat.
■ Environmental cues initiate addictive-like
desire. If every
Thanksgiving you’re exposed to unhealthy sugar, fat and salt
food choices, then everything surrounding the holiday ritual—from
the china plates to particular music, even the streets you travel
on your way to your relatives’ house—all become triggers
that activate your brain’s dopamine production, encouraging
you to eat too much of the wrong foods.
■ How can you stop the cravings? The same
way cigarette smokers inhibit their cravings, says Dr. Kessler. Instead
of looking at high-calorie, unhealthy holiday food as delicious,
deliberately think about its damaging effects on your body. Research
bears this out, says Dr. Kessler, “Attitudes do affect brain
impulses.”
That's a Portion?
Experts at Harvard Medical School say it’s not just that our
brains get hooked on unhealthy food. We also get accustomed to overly
large portions. This holiday season keep yourself in check with these
images of a single-portion size:
One Portion is… |
 |
It’s the size of… |
½ cup cooked rice or pasta |
|
a rounded handful |
1 small muffin |
|
a large egg |
1 pancake |
|
a compact disc |
¼ bagel |
|
a hockey puck |
1 cup salad greens |
|
2 cupped hands full |
1 baked potato |
|
a computer mouse |
1 piece of fruit |
|
a baseball |
2 oz processed cheese |
|
six dice |
3 oz. fish |
|
a checkbook |
3 oz. red meat or poultry |
|
a deck of cards |
1 tsp butter or margarine |

The (Long) Life of Hot Flashes
Hot flashes plague roughly 75% of all women in menopause.
The most effective treatment is hormone therapy, but health risks
associated with it have made many women hesitant to start treatment.
It turns out, their caution may be their good fortune… One
Australian study tracked 438 women from pre-menopause through menopause
and reported that hot flash duration was slightly longer in women
taking hormones: 5.8 years in hormone therapy patients and 5.2 years
in non-users. Amazing-Health Tip: This
same research group found that regular, moderately strenuous
exercise is linked to shorter hot flash duration.
Bottled Water, Friend or Foe
Half of all Americans regularly drink bottled water. But according
to the Natural Resources Defense Council, as much as 40% of it is
just treated tap water. (Unfortunately, bottling plants are not legally
obligated to disclose their water source. You can call the company
and ask, but you may find them uncooperative.) Meanwhile, a University
of Texas study has found that the bacterial content in an opened water
bottle can jump 38-fold in 48 hours if exposed to warm temperature.
So once you open a bottle, refrigerate what’s left and finish
the bottle within two days. Amazing-Health Tip: Why
not consider a water purifying system for your home. For purchasing

Exercise Can Prevent a Cold
A team of Seattle researchers recently concluded that 45 minutes
of moderate exercise, done 5 days a week, may help you avoid
catching winter colds. The investigators enrolled 115 study participants.
Half exercised five days a week for a year; the other half stretched
for 45 minutes once a week. Those who stretched came down with
three times as many colds as the exercisers. Amazing-Health Tip: The
researchers suspect that regular exercise is preventive because
it boosts the immune system
Cinnamon May Lower Blood Sugar
Studies show that even small amounts of cinnamon can lower blood
glucose and improve insulin resistance in people with diabetes.
That’s
the news out of the federal government’s Diet, Genomics and Immunology
Lab. The investigators also found that cinnamon aids digestion
and increases fat metabolism (making it easier to lose weight).
One study found benefit from consuming as little as one-half teaspoon
per day, sprinkled over fruit, on toast or added to cooked meats
and casseroles. Amazing-Health Tip: Some
scientists suspect that cinnamon could affect the
efficacy of prescription drugs; so consult your doctor before trying
this regimen.
FROM OUR READERS:
When using melatonin (or anything that is calming to people with
sleep problems), remember the following precaution… If
you have Central Sleep Apnea (CSA), consult your doctor before
taking anything that affects the nervous system. Anything that
represses the Central Nervous System can affect CSA adversely
and involve a risk . . .
