I personally feel like a good nights sleep is one of the most over rated and under utilized weight loss tools. Without it we’re cranky, moody, unstable and can’t perform our best – but have you thought about the physical repercussions?
Plus, more and more studies are linking sleep with weight loss, and I get it. So much so, that I wanted to write about it.
These are the top 5 reasons why sleep is imperative for weight loss.
#1: The less sleep we have, the hungrier we are.
I don’t know about you, but after a crappy nights sleep I’m not only tired but I also tend to have an unusually bigger appetite. Yeah? You too?? We can blame this on a hormone called ghrelin, also known as the hunger hormone. Gherlin stimulates appetite, increasing food intake and promotes fat storage. Current studies show the more sleep we get, the less ghrelin we have in our systems. So let’s put sleep first and get a solid 8 hours, k?
#2: Cortisol is also regulated by sleep.
Cortisol is responsible for regulating blood sugar and metabolism. Without the proper amount of sleep, cortisol levels are too high increasing hunger then blood sugar, while slowing our metabolism. Double freaking whammy.
#3: We burn less fat.
Researchers have found that even after just 2 weeks of less sleep, fat loss is reduced by up to 55% – it’s the end result of having too much cortisol in our system.
I have no shame in going to sleep when the sun is still up. None at all. This article is making me feel so much better about my 8PM bed time.
#4: Insulin resistance occurs.
Within as little as a few days of reduced sleep, our bodies are unable to use insulin effectively, causing more insulin to be produced to make up for it. Over time, this extra insulin will be stored as fat, instead of being used. Not only will this cause weight gain, but also paves the road to type 2 diabetes.
#5: It ruins our gym effort.
Who can go slay the gym when they’re exhausted? Not me!
