Do you fell that you need to lose weight? Well then don’t
just count calories. You might want to count sheep as well.
Recent studies have shown that sleep deprivation disrupts a series
of metabolism and hormonal processes. It causes increased hunger
and affects the body’s metabolism making it difficult to lose
and control weight.
Lack of sleep causes a hormone called cortisol, which controls
the appetite, to take excess calories and store them as excess body
fat. In addition, sleep loss interferes with carbohydrate metabolism
which may cause high blood glucose levels. The excess amount of
glucose encourages the overproduction of insulin, which may lead
to diabetes or even obesity.
Furthermore, sleep deprivation can promote weight gain by affecting
our behavior. People who lack sleep tended to crave sweets or high
carbohydrate, high fat food with low nutrient value. They tend to
snack on chips, cakes, pastries, burgers, fries, soft drinks, etc.
Though the short-term rise in blood sugar, brought on by these snacks,
gives a surge of energy, the extra calories are not needed by the
body and must be stored as body fat.
These calories are not so easily shed than taken. When they are
sleep deprived, people are often too tired to exercise or they work
out less intensely than usual. They commonly feel exhausted and
lack the energy and motivation to do even simple exercises. They
rather go to sleep, or eat, than go physical. In due time, the calories
that are gained and not easily burned are deposited in the body
as fat.
Some people may require less hours of sleep to be in top condition
during the day; while others need more than 10 hours. But experts
agree that most people need at least eight hours of sleep each night
to give themselves enough energy to exercise, eat right and keep
off those unwanted pounds. Yet, according to a poll sponsored by
the National Sleep Foundation, only 30 percent of adults get eight
or more hours of sleep on weeknights; while 52 percent do on weekends.
A third of adults reportedly sleep no more than six-and-a-half hours
nightly.
In fact, disruption in the sleeping patterns in the United States
and in the industrialized world is thought as one of the main reasons
that people are getting overweight. People should start making behavioral
and lifestyle changes now for a better, healthier tomorrow.
