Why Stress Makes You Eat
Stress is any
change in your normal routine or health. Stress occurs when bad things happen,
as well as happy things. Getting a raise or promotion is stress, just as getting
fired from your job is stress. Speculative changes cause just as much stress as
veritable changes. Pensiveness or anguish about whether you will get that new
job is stress the same as being offered a new position is stress.
Often
people use food to comfort themselves, relieve stress and have something to do
when they're bored or sad. Many people mistakenly use food to accommodate
certain basic needs, such as getting rest, expressing feelings, being
intellectually stimulated and receiving comfort. Food isn't going to supply any
of that. While many people use food in response to emotions like anger,
frustration, loneliness and sadness, stress is felt to be the main cause of
emotional eating.
Imagine that it is mid-
morning and you encounter
unexpected stress. Your boss e-mails you about a huge accounting error
you've made, or your pediatrician calls to tell you your 6-year-old's
lab results are abnormal. Your body goes into fight-or-flight mode.
During a fight-or-flight reaction, your cells demand sugar for fuel
-- and quickly. Unfortunately, on this particular morning, you skipped
breakfast, and supper the night before was ice cream and a diet Coke. |
You
have a minimal amount of circulating blood sugar available to handle your
stressful event. So, your liver releases part of its stockpile of stored blood
sugar. When the stressful event is over, your blood sugar is low and depleted.
Low blood sugar, known as hypoglycemia, causes weakness, anxiety, nervousness,
shakiness and confusion. You feel weak, tremulous and irritable. You reach for a
doughnut or a candy bar because your body craves sugar.
That was not the
best choice. Eating simple sugars and junk foods will indeed raise your blood
sugar, but only for a short time. As soon as that ingested burst of sugar is
metabolized, your circulating levels of blood sugar drops back precipitously
low. And, the cycle of irritability and poor mental performance continues.
So, What can you do?
1. Understand the Stress Response. When
faced with a stressful situation, your brain signals the adrenal glands to
release a hormone called cortisol. Cortisol, in turn, releases glucose and fatty
acids into the bloodstream to provide energy to the muscles. High cortisol
levels result in increased appetite and fat deposits, typically in the cervical
area, trunk and abdomen.

2. Learn How
Stress Impacts Eating. Stress can increase your appetite and make you crave
foods that contain high calories and few nutrients. Unfortunately, researchers
have not yet determined why stress-eaters tend to gravitate toward certain
types of food.
3. Don't Worry, Be Happy. So, what can you do to decrease
stress? Instead of seeking comfort in food, engage in a pleasurable activity
that doesn't involve calories! You might get a massage, visit a friend, read a
book, watch an old movie or play games with your child.
4. Take Charge.
When faced with a stressful event, ask yourself what you can change to minimize
the pressure. Elect to take charge of the situation instead of being victimized
by it. In the process, your body will reduce the amount of cortisol it produces,
which can minimize the harmful effects of prolonged hormone release.
5.
Eat a Variety of Foods. Because stress affects blood sugar, it is important to
eat healthy meals throughout the day to maintain blood sugar levels.
Stress-eaters tend to reach for sugary carbohydrates, so be sure also to
include the recommended amounts of protein and fat in each meal.
6. Eat
Breakfast. A well-balanced breakfast provides protein, carbohydrate and fat
that helps keep blood sugar levels steady throughout the day, reducing the
tendency to reach for a candy bar or soft drink.
7. Replenish Vitamin
and Mineral Stores. Stress causes the body to "burn" more vitamins and minerals,
specifically vitamin B complex, magnesium and zinc; these nutrients are needed
for blood sugar balance. When their levels drop, stress levels increase. Also,
the adrenal glands require more vitamin C and pantothenic acid (part of the
vitamin B complex) during stressful times. To offset these needs, eat fresh
vegetables and fruits daily.
8. Get Physical. Moderate exercise can help
reduce the body's production of cortisol during stressful times. Numerous
studies have shown that moderate physical activity helps modulate mood, reduce
stress, improve self-esteem and program the brain for optimism instead of
pessimism. Do aerobic and anaerobic training on a regular basis, but don't
overdo it. Taking your frustration out during a vigorous workout will further
increase cortisol production.
9. Get Plenty of Rest. Sleep deprivation
affects blood sugar levels, increases cortisol and reduces the production of
leptin (a hormone that signals that you are full). Go to bed a little earlier
each night during trying times and aim for eight hours of sleep.
How do
you know if you're really hungry or if it's stress induced?
There are
several differences between emotional hunger and physical hunger. Emotional
hunger tends to come on suddenly, while physical hunger occurs more gradually.
When you're eating for emotional reasons, you tend to crave a specific food like
ice cream, candy or pizza, and only that food will meet your need. When you're
actually hungry, you're more open to options. Eating for emotional reasons tends
to leave us feeling guilty when eating for physical hunger does not.
Since stress is here to stay, everyone needs to develop methods for
invoking the relaxation response -- the natural unwinding of the stress
response. Relaxation lowers blood pressure, improves respiration, lowers pulse
rates, releases muscle tension and eases emotional strains. This response is
highly individualized, but there are certain approaches that seem to work,
including: exercise, deep breathing, muscle relaxation, meditation and having a
good network of social support.
