Sleep and Weight

Getting a good night’s sleep has a significant impact on health, energy and even your weight.  Not getting enough sleep will not only will make your body and mind tired, but will also increase your appetite and your waistline.

Research has shown that sleep deprivation:

  • Elevates cortisol levels, which increases appetite and fat deposition.  (Studies show markedly elevated cortisol levels even after just one night of poor sleep.
  • Increases Ghrelin production.  (Ghrelin is your hunger hormone.) The more Ghrelin you produce, the hungrier you are.
  • Impacts insulin production, which can increase appetite and fat storage.
  • Is inversely related to BMI.  Meaning the less sleep we have the more likely our BMI will be high.
  • Makes us more susceptible to immediate gratification eating behaviors.  It can be more difficult to stick to our plan if we feel tired and are just trying to make it through the day – a quick treat looks really tempting!

So how much sleep is enough?

Most research states that 7 hours is the minimum.  While we are not sleep experts, we recommend asking yourself if you are well rested in the morning and going from there. You might need 8 or 9 to feel fully rested.
