Today we look at the many factors related to why we seem to over eat when we are overtired.
If we sense that sleep deprivation makes us crave fattier or sugary foods, we are not imagining it. There are both biological and psychological factors messing with our brain.
The hormones that are triggered when we are either hungry or full will be on altered with only one or 2 nights of sleeplessness.
There are a few articles that I mentioned in this podcast.

They are:

The Mayo Clinic article on sleeplessness and weight gain

The New York Times article on sleep deprivation and weight gain.

There is an excellent podcast episode on this subject. It is Dan Harris is podcast called "10% happier", episode 21, with Arianna Huffington.
