People who get around eight hours sleep a night and reduce their stress levels have double the chance of LOSING WEIGHT
This is directly linked to spike in cortisol levels which in turn leads to creation of glucose and consequently stimulating insulin .
Why Fat is important
Fat in its entirety in your body actually produces hormones that your body depends
on, and one of those very important hormones is called leptin.
Leptin is simply referred to as the Satiety hormone . and when sleep deprived its production is cut leading us to crave unhealthy foods.. ( That may be the reason why I always feel like a Macdonalds after a night shift!!!)
Leptin has a function all over your body, it's correlated to brain size. So people who
are anorexic, their brains actually start shrinking because they don't have enough fat,
they don't have enough leptin to maintain brain mass.
