How Late Night Eating Makes You Fat
Nerd
Alert! This
article is a bit technical, so please skip it if you're adverse to words
like "neuron" and "circadian rhythm."
This month’s issue of The Scientist magazine
has an interesting article on how our bodies are designed to eat at
certain times of day and rest during others. Break this pattern and there
are serious consequences.
“Originally, it was thought
that our circadian rhythm” (sleep-wake cycle) “was attributed entirely to
about 20,000 neurons in the brain known as the suprachiasmatic nucleus
(SCN). The SCN was believed to be the master clock that dictated the
body’s 24-hour rhythms.” But
new research indicates that many of the body’s tissues can tell time as
well."
The significance of this is
that the master
clock tells the body how and when to burn or store energy (think
metabolism).
You want your body to burn
reserves like fat during the day and store energy at night.
But if you eat at night when
the body should be sleeping, your
cells gets confused and your body get’s conflicting
messages.
The end result is that your body ends up storing excess
energy (i.e. fat) and doesn’t burn it as efficiently
during the day. More research needs to be done to determine which part of
your body is really in charge (your brain or the individual tissues), but
it’s clear that the master clock needs to be honored for your metabolism
to work as it was designed.
