How Sleep Affects our Brains
Even a single night of sleep deprivation makes fattening, high-calorie foods more attractive and at the same time interferes with the brain’s ability to override desire with rational decision-making.
How Sleep Affects our Calorie Burn
Your body burns the most calories during REM sleep. Your REM sleep increases the longer you sleep.
Therefore, if you sleep less hours, you miss that prime calorie burning window by cutting off the tail end of REM (or the longest period of REM where you could burn the most calories).
