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 control and
lose
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.
