Sleep impacts how your body functions physically, mentally
and emotionally and has dramatic effects on your ability to lose weight.
In the book "Why We Sleep" by Matthew Waker he describes an experiment
where they took healthy people and compared how they ate when
given 8 hours of sleep a night vs. 4-5 hours.
What they found out was shocking. When sleep deprived the participants ate
an average of 300 more calories a day compared to when they were fully rested.
There are 3 key reasons this happens when sleep deprived...
First, your body produces more Ghrelin, which is the hormone your
body releases to signal you to eat, making you hungrier.
Second, your body produces less Leptin, the hormone that lets
your body know you've eaten enough, keeping you hungry.
Finally, the Amygdala (a part of your brain responsible for strong emotions such as anger)
showed a 60% amplification in emotional reactivity, leading to more emotional eating.
All of these things make it more difficult for you to lose weight.
But, if you get the proper amount of sleep, your body begins supporting you, making it easier.
To a good night's sleep.
