00:01
does sleep affect
00:03
weight management the global health cost
00:06
of obesity
00:07
is estimated to be more than two
00:09
trillion studies show
00:11
that the less you sleep the more you are
00:13
likely to eat
00:15
studies have found that when they
00:17
compare individuals to themselves
00:19
when they've either slept eight hours or
00:20
slept four or five hours a night
00:22
those same individuals will report
00:25
stronger hunger pangs
00:26
and increased appetite even when they've
00:29
been fed the same
00:30
amount and given the same amount of
00:31
activity so it seems that
00:33
inadequate sleep decreases
00:36
concentrations of the hormone leptin
00:38
which signal to our body
00:39
that we feel full inadequate sleep also
00:42
increases the levels of the hormone
00:44
ghrelin
00:44
which signal to our body that we are
00:46
hungry
00:48
and it's not just about eating more when
00:50
you haven't slept well
00:51
research also shows that we tend to
00:54
crave
00:55
more sweet carbohydrate-rich foods and
00:58
salty snacks
00:59
when we haven't slept well it seems that
01:02
the lack of sleep
01:03
impacts the areas of our brains that are
01:05
associated with self-control
01:08
as the more emotional areas of the brain
01:10
then amplified and take over
01:12
the more high calorie foods become more
01:15
desirable
01:16
and we have more trouble stopping
01:18
ourselves from eating them
